Interchange Recharged

We're looking back at some of our most popular episodes of the year. Here is one from January this year.US data centre announcements are averaging 435MW a month, and there’s around 175GW of large-load capacity already committed or under construction. AI hyperscalers are looking for innovative ways to meet their energy demands. It’s one of the biggest infrastructure challenges in energy right now: how to deliver reliable, fast power without derailing climate and decarbonisation goals. Joining interim host Bridget van Dorsten is Akhil Batheja, Director of Technology Strategy at Bloom Energy, to unpack why fuel cells have moved from “interesting clean technology” to the epicentre of the data-centre power conversation - and what that shift means for utilities, energy projects, and energy policy.Together they discuss how solid oxide fuel cells differ from turbines, engines and batteries - from efficiency and permitting advantages to “Lego block” scalability - and why “time to power” is becoming the defining…

After more than a decade of flat demand, the US power sector is now facing explosive growth, arriving faster than grids, generation, and transmission can be built. In this episode, Interim host of Interchange Recharged Bridget van Dorsten is joined by Chris Seiple, Vice Chairman of Power & Renewables at Wood Mackenzie, to unpack one of the defining challenges facing the modern energy system: how utilities, developers, and policymakers are responding to an unprecedented surge in electricity demand driven by data centres, AI, and reshoring manufacturing. Bridget and Chris explore what makes this moment different, why planning cycles are colliding with short technology investment horizons, and how this mismatch is forcing a fundamental rethink of how the power business works, from energy policy to energy finance. The main point is that the difference between regulated and deregulated markets is widening, as vertically integrated utilities strengthen their advantage in managing large loads.New mechanisms like…

Colombia’s power system was built around a powerful advantage: abundant hydropower backed by domestic gas, delivering electricity that was relatively cheap, relatively clean, and largely local. But that model is coming under pressure from two directions at once. Climate volatility is making dry years more dangerous, and gas is no longer the easy fallback it once was. As a potentially severe El Niño approaches, the central question is no longer just how much installed capacity the country has on paper. It is whether the system has enough firm, flexible energy to meet rising demand without driving up prices or risking shortages.Host Sylvia Leyva Martinez is joined by Álvaro Villasante, Vice President of Business Management and Innovation at Grupo Energía Bogotá, to examine how that shift is changing the energy debate in Colombia. Their core argument is that hydropower remains a strategic strength, but it can no longer be treated as a sufficient foundation on its own. As gas production declines and imports…

The pressure on the power system is no longer theoretical. AI, data centers, electrification, and new industrial load are arriving faster than utilities can build generation and transmission through conventional timelines. One of the least glamorous but potentially most consequential answers to that problem is how to get more capacity out of the wires already in the ground and hanging overhead. Host Sylvia Leyva Martinez is joined by JD Sitton and Theodore Paradise of CTC Global to examine why advanced conductors are moving from a niche grid technology to a mainstream tool for utilities under pressure to deliver speed, affordability, and reliability at the same time. They explain how replacing traditional steel-core conductors with carbon-core alternatives can sharply reduce sag, increase thermal performance, and in many cases double capacity on existing rights-of-way without rebuilding towers or waiting a decade for a new line.The conversation explores why that matters now. As Theodore argues, the grid was…

After a decade of flat demand, power markets are being forced to absorb a very different problem: rapid load growth arriving faster than transmission, large-scale generation, and utility interconnection processes can respond. The focus shifts from utility-scale procurement to the distributed edge of the system, where commercial and industrial solar, community solar, batteries, and microgrids may prove to be some of the fastest tools available for adding capacity, managing costs, and improving resilience.Host Sylvia Leyva Martinez is joined by Tim Montague, host of Clean Power Hour and a longtime C&I solar operator and advisor, to unpack what distinguishes distributed generation from utility-scale solar in practice. Tim explains why the differences are not just about megawatts, but about interconnection, contractor capability, state policy, and execution risk. He also lays out how the phase-down of the ITC and the July 4 Safe Harbor deadline sharpened those differences: sophisticated developers with capital…

Electricity demand is rising, capital is tightening, and nuclear is back in the conversation as utilities, governments, and large power users look for firm low-carbon supply. But the central question is not whether advanced nuclear can attract interest. It is whether any new design can get far enough ahead on cost, manufacturability, and fuel strategy to break from the economics that have constrained conventional nuclear for decades.Host Sylvia Leyva Martinez is joined by Thomas Jam Pedersen, co-founder and CEO of Copenhagen Atomics, to examine one of the more unconventional answers now being put forward: thorium molten salt reactors built around low-pressure operation, standardized manufacturing, and a fuel strategy that could use spent nuclear fuel alongside thorium. Their core argument is that most of the nuclear sector is still trying to improve on a legacy light-water model that may remain too expensive, too complex, and too slow to scale against the pace of future energy demand.A large part of the…

Solar demand remains strong, storage is scaling fast, and inverter technology is becoming more central to how modern power systems actually function. But the conversation around inverters is no longer just about efficiency, bankability, or price. As these devices take on more intelligence — managing batteries, supporting grid stability, and communicating more directly with the wider system — they are also being treated as a new point of strategic vulnerability. In both Europe and the US, policymakers are starting to respond accordingly.Host Sylvia Leyva Martinez is joined by Joe Shangraw, research analyst at Wood Mackenzie covering solar inverter markets, to examine what that shift means in practice. Their core argument is that inverter policy is moving beyond trade protection and into a more complicated mix of cybersecurity, industrial strategy, and grid risk. They unpack why Europe’s March decision to block public EU funding for projects using Chinese-made inverters matters beyond its immediate scope, and…

Copper is moving from background commodity to frontline constraint. Demand is rising fast, high-grade deposits are getting harder to find, and the lead times for bringing new supply online remain brutally long. That matters not just for renewables and electrification, but for the basic energy resilience of modern life: the wires that keep lights on, water running, refrigeration working, and data centres scaling all depend on a metal the industry already knows is becoming harder to source.Host Sylvia Leyva Martinez is joined by Liz Dennett, founder and CEO of Endolith, whose career spans Wood Mackenzie, AWS, and NASA-linked astrobiology research, to explore a biological approach to one of mining’s toughest problems. Endolith uses microbial communities, what Dennett calls “the world’s oldest miners," to help recover more copper from low-grade ore in existing heap leach operations. The company’s core thesis is that copper supply can be made more elastic not by rebuilding mine sites from scratch, but by layering…

Wind remains fundamentally healthy: electricity demand is rising, decarbonised power is still needed, and both Europe and the US continue to pull new projects forward, albeit for different reasons. But the industry’s center of gravity is shifting. The conversation is no longer just about building faster or installing more megawatts. As turbines get larger, OEM competition broadens, and project economics tighten, the consequences of failure are becoming much harder to ignore.Host Sylvia Leyva Martinez is joined by Alexis Grenon, CEO of Onyx Insight, and Olly Litterick of Tokio Marine GX to examine what that shift means in practice. Their core argument is that the wind sector is moving from a development-at-speed mindset toward operational efficiency, where every dollar of ROI matters and risk has to be quantified far more precisely. They unpack why insurers still struggle with newer turbine classes despite two decades of renewables underwriting: the machines are scaling faster than the loss history, the…

As AI systems scale, the infrastructure challenge is no longer just about chips, models, and software performance. It is increasingly about the physical systems that allow computation to happen at all: power delivery, cooling, water access, and the speed at which new capacity can be brought online. Power conversion is becoming a much more important design question. As racks move from conventional power densities toward megawatt-scale configurations, every inefficiency in the electrical pathway becomes more consequential. For stakeholders across the energy sector, that makes AI infrastructure more than just a datacenter story. It is also a story about grid constraints, industrial load growth, thermal management, and how developers can design facilities that are efficient enough, flexible enough, and resilient enough to operate at the scale AI now demands.Host Sylvia Leyva Martinez is joined by Nick Wright, Vertical Solutions Manager at Siemens. Their conversation explores why the growth of the AI factory is…

A year ago the data centre conversation was about scale. Increasingly it is about what happens when the announcements meet the physical grid. New capacity is being announced at roughly 435 megawatts a month, enough to power a city of 400,000 people, but two-thirds of that committed load tends to disappear the moment utilities ask for a financial commitment behind it. AI training facilities create load profiles that drop 30% in five minutes, or 190 megawatts in three. The grid's mechanical inertia is retiring just as hyperscaler ambition accelerates, and regulation is lagging on both sides of the meter.In this episode, interim host Bridget van Dorsten returns the microphone to host Sylvia Leyva Martinez. The two recap six months of the show through clips from Chris Seiple (Wood Mackenzie), Tom Falcone (Large Public Power Council), Akhil Batheja (Bloom Energy), Kay Aikin (Dynamic Grid), Kristina Carlquist and Christian Payerl (ABB), Shannon Miller (Mainspring Energy) and Nick Chaset (Octopus US), and map out…

The energy transition conversation focuses on what connects to the grid. Far less attention goes to whether anyone is coordinating what those assets do once connected. AI training runs swing hundreds of megawatts in seconds as GPUs checkpoint and restart a profile that looks like a generator tripping offline. At distribution level, millions of inverter-based resources create localised variability that overwhelms individual circuits even when aggregate models look healthy. The planning tools in use today were designed for neither problem.Host Bridget van Dorsten is joined by Kay Aikin, CEO and Founder of Dynamic Grid, energy engineer, grid architecture advisor to the DOE-supported GridWise Architecture Council, and contributor to the UN Environmental Program's building decarbonisation work. Kay unpacks what an AI training facility actually does to the grid with full GPU load for hours or days, then a drop to ten percent in seconds during checkpointing. She talks about how at the scale now planned, the…

As coal and gas plants retire, the energy transition conversation focuses on replacing their generation capacity. What gets far less attention is the loss of the physical properties those machines provided for free: inertia that stabilises frequency, fault current that supports voltage during disturbances, and reactive power that regulates voltage across the network. These services come from the physics of enormous spinning rotors synchronised to the grid, responding instantaneously, without sensors, software or control loops. As inverter-based resources replace them, that mechanical immune system disappears, and a new, extreme stress test is arriving at the same time in the form of AI data centres whose loads can swing by hundreds of megawatts in a fraction of a second.Host Bridget van Dorsten is joined by Kristina Carlquist, General Manager of Synchronous Condensers at ABB, and Christian Payerl, Sales Manager of Synchronous Condensers at ABB, to unpack why a technology that has existed for as long as the…

Utilities are under pressure to deliver generation that is dispatchable, affordable, and clean enough to satisfy increasingly stringent environmental rules, notoriously hard to do in one asset. As renewables grow, the gas turbines and engines that have historically filled the gap come with a NOx problem, a CO2 problem, or both. Hydrogen offers a path through, but the supply isn't there yet. So what do you build today?Host Bridget van Dorsten is joined by Shannon Miller, CEO of Mainspring Energy, and Will Hazelip of National Grid Ventures, to dig into a technology most listeners haven't heard of and the first commercial hydrogen-powered deployment of it. Mainspring's 250-kilowatt linear generator is being installed at National Grid's 1,500 MW North Port facility on Long Island, in partnership with NYSERDA, the Long Island Power Authority, and Stony Brook University.Shannon explains how Mainspring redesigned the generator using the power electronics that drive solar inverters, batteries and EVs, replacing…

Empty gigawatt factories, product recalls, participation rates that never materialised, and a policy environment that has now stripped the green premium entirely. The electrolyzer industry has had a brutal few years and most of the companies that raised hundreds of millions on the back of the hydrogen hype cycle are now sitting with fixed costs they cannot sustain and field deployments they are not proud of. Host Bridget van Dorsten speaks with Raveel Afzaal, CEO of Next Hydrogen, one of the few electrolyzer manufacturers that chose to watch from the sidelines while competitors scaled into the storm. Raveel describes the decision in blunt terms: in 2021, when cost of capital went to near zero and capital discipline evaporated, Next Hydrogen looked at the macro signals; rising inflation, rising interest rates, a market telling them their Hyundai partnership was worth a 5% share price drop, and chose to extend their runway from 18 months to five years. That meant hard capital allocation decisions, and the…

Millions of enrolled devices, 60 utilities, and the participation rate gap that's been embarrassing the US market for a decade. US residential virtual power plants have been a promising idea that's consistently underdelivered — participation rates below 5%, fragmented apps, siloed programmes, and utilities that have simply never had to compete for a customer's attention. Meanwhile, Octopus Energy has built the world's largest residential VPP in the UK, with EV driver participation rates of 50 to 70%. The question has always been whether that model can travel to a market where most customers have no supplier choice at all. Bridget van Dorsten speaks with Nick Chaset, CEO of Octopus Energy US, about the acquisition that represents Octopus's biggest bet on answering that question: a majority stake in Uplight alongside Schneider Electric, giving Octopus access to established relationships with more than 60 US utilities — including eight of the ten largest. Nick argues the participation gap isn't really a…

Why nuclear has never been project financed and how that might finally be about to change.Every nuclear plant ever built has ultimately been backstopped by taxpayers or ratepayers. Not because the technology doesn't work, but because nobody has ever cracked the construction cost and schedule problem well enough to convince a bank to finance it without government support. Bridget van Dorsten is joined by Jake Jurewicz, Co-founder and CEO of Blue Energy, to explore why that has been so hard and what a credible path to fixing it might actually look like.Jake walks through the root cause of nuclear's cost overrun problem and it is not the reactor. The reactor equipment itself represents around 7% of total project costs. The real problem is what Jake calls nuclear construction overhead: the cost of mobilizing, training, and retaining the 10,000 or so skilled workers needed to build these plants in the field, the way we have been building them for 70 years, essentially the same way you would build a castle.The…

What two decades of flat demand means for a grid now expected to double in sizeThe US went from essentially zero load growth for twenty years to 3% national growth almost overnight. The supply chains, permitting pipelines, engineering workforce and regulatory processes were all calibrated for a different world. Bridget van Dorsten is joined by Tom Falcone, President of the Large Public Power Council, representing the 30 largest publicly owned utilities in the United States, collectively owning around 85% of public power assets and currently serving roughly 18% of all US data centre load. Tom explains what makes public power structurally different from investor-owned utilities: locally governed, not-for-profit, and built to minimise cost rather than earn a return on equity. That governance model turns out to matter a great deal when trillion-dollar hyperscalers come looking for power. Public power utilities have no financial incentive to favour their own assets over a customer's, and their local…

Carbon capture and storage has long been framed as a clean technology that’s forever five years away. Bridget van Dorsten speaks with Tim Vail, CEO of ION Clean Energy, to explore why a surge in AI data-centre demand is reshaping the market for decarbonised gas – and how viable a solution it really is.Tim argues we’ve entered a buyer-led era for carbon capture, driven by hyperscalers like Amazon, Google and Microsoft who need 24/7 power fast - but are still committed to climate and decarbonization goals. That creates a new question for the energy transition: can natural gas + CCS deliver competitive renewable energy-level carbon intensity, while supporting grid resilience and scaling quickly enough for near-term energy projects?A big part of the conversation is about measurement and credibility. Tim explains how “carbon intensity” has to be assessed across the full value chain - from wellhead to electrons - including methane leakage. The rise of methane monitoring (ground, aircraft and satellite) and…

After more than a decade of flat demand, the US power sector is now facing explosive growth, arriving faster than grids, generation, and transmission can be built.

AI is changing the energy system faster than almost anything we’ve seen in decades. Interim host, engineer and energy analyst Bridget Van Dorsten is joined by Ed Crooks, host of Energy Gang and Vice-chair of the Americas at Wood Mackenzie, for a wide-ranging conversation about what’s really driving energy decisions in 2026. From data centres and “speed to power” to energy affordability and US energy dominance, they unpack why reliability, cost and scale are now front of mind for governments, utilities and technology companies.Bridget and Ed discuss which technologies could step up to meet the demand, from long-duration storage and advanced nuclear to geothermal and grid-enhancing technologies, and whether AI itself could help accelerate innovation across the energy system. Then they debate the costs; how much does AI really cost us in emissions and capital that could arguably be better spent elsewhere. Are data centres out-competing the energy transition for capital and grid access? And what happens if…

At the start of the year things were looking uncertain for nascent renewables like hydrogen and geothermal. With policy support from the previous US administration they had boomed with the IRA, then came July 2025 and the Trump administration’s One Big Beautiful Bill, which tore up tax credits and removed incentives for those renewable technologies. As we approach the end of the year, has anything changed for the better? How are hydrogen, wind and geothermal looking as we prepare for 2026?Regular host Sylvia Leyva Martinez is on maternity leave until the middle of next year, so her fellow energy analyst Bridget van Dorsten is stepping up to keep the mic warm. Bridget is an analyst researching hydrogen, but she has an engineer’s understanding of technologies across the energy spectrum. She doesn’t just cover that ‘frustrating, inefficient, expensive-to-move-around molecule’ (as she calls it); she knows what’s real in the energy world and what’s just hype. To kick off her tenure as host she’s picked out a few…

Utility-scale clean energy projects in development are still facing connection queues and regulatory barriers. RE+ may be done for 2025, but the debate is still going. Host Sylvia Leyva Martinez, Research Director at Wood Mackenzie, sits down with three leaders who are driving progress from different corners of the energy transition, from utility-scale project development to digital grid optimisation and solar system reliability. Sylvia Leyva Martinez and her guests discuss how federal and state regulations shape project timelines and financing, the latest innovations in the grid and the future of interconnection studies, the supply chain outlook for developers and technology providers, and how policy and software are converging to accelerate the energy transition. In this episode you’ll hear from: Angela Amos from AES Clean Energy - As Director of Commercial Strategy & Innovation, Angela brings a unique vantage point that bridges policy, finance, and market execution. Drawing on her experience at AES,…

Electrification is surging, AI data centres are multiplying, and volatility is rising on both sides of the meter. Can storage step in as the flexible backbone the US grid now needs? Host Sylvia Leyva Martinez is joined by Joanna Martin Ziegenfuss, General Manager for Strategic Market Development (North America), and Ruchira Shah, General Manager of Software Product Management at Wärtsilä Energy Storage. Together they unpack how high-performance hardware paired with sophisticated control software delivers real-time flexibility, from synthetic inertia and fast frequency response to price arbitrage and microgrid operation. The conversation tracks the shift from treating storage as a bolt-on to renewables to viewing it as a core reliability asset. Sylvia, Joanna and Ruchi explore how AI-driven load growth and volatile demand profiles change planning assumptions; why interconnection queues are pushing some data centres toward on-site generation plus batteries; and how market rules and policy must evolve to reward…

This special wrap-up episode of Interchange Recharged takes listeners on a fast tour of the entire carbon capture value chain, from industrial emitters and LNG developers to UK transport and storage pioneers. Host Sylvia Leyva Martinez, Research Director at Wood Mackenzie, brings together three leaders shaping how CCUS moves from theory to reality.First, James Lopez, Subsurface CO₂ Storage Advisor at CEMEX, explains why cement’s process emissions make it one of the hardest sectors to decarbonise and why storage certainty is now the key enabler for investment. He shares how CEMEX is identifying and evaluating CO₂ storage hubs across global sites, and why capture without a permitted storage solution is a business risk few emitters can take. “CCUS doesn’t work if you only have the C,” he says, “you need the full chain.”Next, Glenn Wilson, Chief Financial Officer at Coastal Bend LNG, discusses how LNG economics and carbon capture can work hand in hand. Designed from day one as a low-carbon project, Coastal Bend…

Recorded live on day two of Wood Mackenzie’s CCUS Conference in Houston, this episode of Interchange Recharged explores how carbon capture is advancing from state-level regulation to real-world innovation and global market trends.Host Sylvia Leyva Martinez begins with Lily Barkau, Groundwater Section Manager at the Wyoming Department of Environmental Quality, who explains how Wyoming became one of the first states to secure Class VI primacy and why local leadership is key to building trust, speeding up permitting, and ensuring long-term stewardship of CO₂ storage.Next, Katherine Hough of GEVO connects policy with practice, describing how her team links biogenic CO₂, carbon sequestration, and sustainable aviation fuel to create a truly circular carbon economy. Her insights show how business models, not just technology, are making carbon management commercially viable.Finally, Sylvia sits down with Ed Crooks, Vice Chair, Americas at Wood Mackenzie and host of Energy Gang, for a wide-angle look at how policy…

This special episode of Interchange Recharged brings together finance, law, and technology leaders shaping the path to commercial carbon capture. Host Sylvia Leyva Martinez explores how capital, regulation, and innovation are converging to turn early-stage CCUS projects into bankable reality.The conversation opens with Omer Farooq, Head of Sustainable Asset Finance at Bank of America, on how one of the world’s largest banks is approaching carbon capture — from financing first-of-a-kind projects to assessing new business models and risk structures. Omer explains why point-source capture is already investable, why direct air capture still has hurdles to clear, and why incentives like 45Q remain the backbone of the economics. “Policy drives energy,” he says, “and transport and permitting are the next frontiers.”Next, Liz McGinley, Partner at Bracewell LLP, joins to unpack the evolving U.S. regulatory landscape. She discusses the expanded 45Q tax credit, the lingering uncertainty around the Greenhouse Gas…

As RE+ 2025 wrapped up in Las Vegas, the mood across the show floor was one of contradiction: anxiety, anger, optimism, and opportunity all rolled into one. In this episode, Sylvia Leyva Martinez – Research Director and analyst covering global solar markets - sits down with Chris Seiple, Vice Chair of Power & Renewables, and Kasim Khan, Senior Analyst at Wood Mackenzie, to unpack the forces shaping today’s energy market. From the shockwaves of OB3 and FEOC restrictions, to investors navigating the whiplash of shifting subsidy regimes, Sylvia, Chris and Kassim talk about the conversations they’ve had with developers and manufacturers. Everyone is facing the same dilemma: double down on building compliant supply chains or hold back in anticipation of yet another policy reversal? Meanwhile, the collapse of early-stage development activity and the race to prove FEOC compliance are reshaping priorities across the industry.But there’s more than just uncertainty, there’s also innovation. Utilities are experimenting…

Recorded live at RE+, Sylvia Leyva Martinez, Research Director at Wood Mackenzie, hosts Ryan Chen and Neil Bradshaw from Hithium to unpack the true costs of OB3, the constraints on innovation and fire safety as result of the bill, and the future possibilities for AIDC.Neil Bradshaw is Director of Global Applications Engineering, and takes the view that even US manufacturers aren’t immune from the OBBA’s sweeping impact on supply chains: “imagine you are a manufacturer based in the US but you're importing parts, and all of a sudden you have a policy that comes through that changes how you bring in parts and maybe you can't find local cells or you can't find a certain component,” he says. How are manufacturers responding to this uncertainty? How are they planning for the next few years, never mind decades?Ryan Chen is Chief of Staff to the Chairman at Hithium, and he shares with Sylvia how Hithium is betting big on Texas manufacturing, investing before they even had offtake agreements in place. You’ll hear how…

Despite the US adding 4.3 gigawatts of solar manufacturing capacity in Q2, there were no additions to the upstream components of polysilicon wafer and cell manufacturing. As gas prices continue to rise and the demand for alternative power supplies grows, get a detailed look at what big names in energy are doing to get over the hurdles. On her second day at RE+ in Las Vegas, Sylvia Leyva Martinez, Research Director at Wood Mackenzie, explores the trajectory of solar and storage. Alongside industry experts, this episode of Interchange Recharged discusses the exciting yet challenging future of solar energy and energy storage amidst changing policy landscapes and growing demand. Sylvia and her guests explore and explain the dynamics of solar capacity, regulatory and financial challenges such as One Big Beautiful Bill (OB3) accelerating the phase-down of key tax credits, and emerging technologies fueling the renewable energy sector. This episode includes an exclusive excerpt from Sylvia’s presentation with the…

In a year defined by uncertainty, this RE+ special episode of Interchange Recharged flips the script from “build more” to “get more from what you’ve got.” Sylvia Leyva Martinez, Research Director at Wood Mackenzie, is joined by Alex Bamberger, VP of Digital Solutions at RES, to look at how owners are squeezing extra megawatt-hours from operating wind, solar and storage, opening OEM-level data, pairing software with smart hardware, and retuning controls for site realities. You’ll hear real uplift figures (think low-single-digit AEP gains that add up to a year’s worth of new installs at fleet scale) that show how new tech is optimising renewable energy assets.Then we widen the lens to the grid itself. Systems architect and founder and CEO of Dynamic Grid Kay Aikin makes the case that smarter controls, storage and flexible demand can raise distribution utilisation far beyond today’s approximate 45%. Sylvia and Kay look at how performance-based models could unlock faster, cheaper reliability without waiting on…

The policy environment in the US at the moment is challenging, but developers, utilities, and investors are still moving forward with decarbonisation goals and climate action; they’re just talking about it and approaching it in a different way. As RE+ (North America’s biggest clean energy event) kicks off, Sylvia Leyva Martinez talks to veteran climate journalist and cleantech investor Molly Wood, about the ways in which the industry is navigating the uncertainty. Molly talks about the outdated forecasts of 1–2% load growth which are being blown apart by real demand increases of up to 30% in some regions, driven by electrification, AI, and data centers. If you can’t make it to the event this year, Interchange Recharged will bring you the key discussions and exclusive insights so you don’t miss out. You’ll hear why traditional load forecasts are being upended by surging demand from AI and data centers, and what that means for project planning and risk management. Despite policy headwinds, the money is still…

EV growth is moving, but is it moving quickly enough? Wood Mackenzie research projects battery electric vehicles to account for 58% of light vehicle sales globally by 2050. It won’t be until 2045 that EVs surpass ICE vehicles on the roads globally. So how can consumers be incentivized to get an EV? Manufacturers are addressing concerns around range anxiety and price, so what else is there to tempt buyers? Perhaps shifting the conversation from EVs as just low-carbon emitting cars to seeing them as energy assets might do the trick. Could vehicles reliably charge your house? Or even stabilize the grid during peak demand? To find out, host Sylvia Leyva Martinez speaks with GM Energy’s Aseem Kapur about their two-way charging EV project. They explore the potential of vehicle-to-home and vehicle-to-grid systems, the lessons from early pilots, the importance of interoperability standards, and how incentives and customer trust will drive EV adoption – something that needs to accelerate if we’re to stay on track for…

Way back in 2016, US energy storage capacity had just hit 336MWh, a 100% year-on-year increase. The growth forecast for storage was for 7.3GWh by 2022 – a US$3.3 billion market. It’s just one example of how far we’ve come; the IRA’s tax credits and incentives created a bullish environment for developers, and the renewable project pipeline grew and grew. Then came OB3, and the uncertainty around the future of the tax credits slowed everything down in the first half of 2025. However, a key market condition still exists: the ability to transfer tax credits. It’s a new market and one that could prove crucial for financing renewable projects. So how does it work? And what can it offer developers and financers? To find out, host Sylvia Leyva Martinez – a principal analyst at Wood Mackenzie covering global energy markets – is joined by Alfred Johnson, CEO of Crux. Crux facilitates the raising of capital, including the sale of tax credits and debt capital. Sylvia and Alfred review the last few years of clean energy…

The uncertainty rippling through the energy industry in the first half of 2025 hasn’t gone away. Utilities, developers, and manufacturers are still grappling with the fallout from the "One Big Beautiful Bill," the Trump administration’s reversal of parts of the Inflation Reduction Act, and the evolving tangle of trade tariffs.Sylvia Leyva Martinez, host and principal analyst at Wood Mackenzie, is joined by her colleague Kelsey Coffman, Vice President of Supply Chain Consulting at Wood Mackenzie, to analyse how clean energy producers and buyers are adapting to the changes.The cost of batteries and solar panels is skyrocketing; tariffs as high as 145% are disrupting billion-dollar projects. How did we get here? And what can be done? Plus, changing definitions of “foreign entities of concern” – the new rules could kill access to tax credits if suppliers have indirect links to China. Sylvia and Kelsey debate the best path through the FEOC minefield. And how big have the risks of project delays and cancelled…

Despite uncertainty for US clean energy investors, things are looking good for the geothermal sector. US$1.7 billion in public funding was pumped into geothermal projects in Q1 this year - 85% of 2024's entire annual allocation – as breakthrough technologies promise to transform untapped resources into commercially viable clean energy projects.Enhanced geothermal and advanced geothermal technologies are making geothermal energy accessible anywhere, not just at existing sites chosen for their high-temperatures.To explore the science behind EGS and AGS, host Sylvia Leyva Martinez is joined by John Plack, VP of engineering at Ameresco. John explains how techniques adapted from the oil and gas sector, like directional drilling and reservoir stimulation, are improving geothermal's commercial viability. John shares what’s changed since the IRA’s passage, the role of EGS, and why improved subsurface mapping is critical to unlocking investment.Geothermal is currently supplying less than 1% of global energy needs,…

In February this year BP announced it was cutting its investment in green energy ventures from $5B to $2B while reallocating $10B to fossil fuels, and abandoning its 2030 oil output reduction target. Shell has also scrapped its planned 20% carbon reduction cut for 2030. It’s not a good display of intent from the perspective of the energy transition. In a highly volatile and uncertain policy environment it’s troubling for investors and clean energy developers. The prioritisation of short-term profit at the expense of long-term climate impact has many implications.To find out, host Sylvia Leyva Martinez is joined by private investor Ben Dell, Managing Partner at Kimmeridge. He says that while “everyone wants low-cost energy on demand with a minimal carbon footprint, every dollar invested has to be cost-competitive. Philanthropy is not an investing strategy.” What does that mean in the context of clean energy deployment?Plus, Wood Mac analyst Tom Ellacott joins the show to look at the outlook for oil and gas in…

The Greenhouse Gas Protocol – the global gold standard for measuring corporate emissions – is under review, and the proposed changes could dramatically reshape how clean energy is bought, sold, and reported. New draft rules are expected by the end of the year.What changes could we see? And how will they impact the energy transition? To find out, Sylvia Leyva Martinez, principal analyst at Wood Mackenzie covering solar markets, speaks with Lee Taylor, CEO of Resurety – a leading provider of data and analytics for clean energy buyers. Lee has spent over a decade helping companies understand not just how to procure renewables, but how to do so with real carbon impact.Together, they explore what’s changing in Scope 2 emissions accounting, why location and timing of energy use now matter more than ever, and how voluntary clean power markets might evolve. They break down complex concepts like emissionality, 24/7 procurement, and consequential accounting – and what these mean for corporate net-zero strategies, PPA…

Nearly 150 days into President Trump’s second term, the outlook for wind energy in the United States - particularly offshore wind - is increasingly bleak. Trump had pledged to end offshore wind development, and now the House Ways and Means Committee is proposing a phase-out of tax credits for renewables by 2031 - a move that would severely impact an already struggling wind sector (over on our sister podcast Energy Gang, we discuss the bill and what it means for renewables – check out that episode once you’re finished here).Only three offshore wind projects have come online in US waters, with 4 GW currently under construction. In 2024, total wind installations reached a ten-year low at just 5.2 GW. By contrast, Europe has surged ahead, having built 35 GW of offshore wind capacity - ten times the US total – emphasising the stark differences in policy and financing frameworks.Still, there are glimmers of hope: President Trump recently lifted a stop-work order on a $5 billion offshore wind farm off the coast of…

The US is risking ceding global market share of clean energy to China, permanently.New tariffs, put in place one day then removed the next. Rising costs for everything along the supply chain. The US clean energy sector is navigating one of its most unpredictable phases yet. From solar to storage, how are developers and policymakers reacting to renewed trade tensions and their impact on the energy transition? “This isn’t just about clean energy deployment. It’s about whether the US will have a seat at the table in the future global energy economy,” says Leslie Abrahams, Deputy Director of the Energy Security and Climate Change Program at CSIS – the Center for Strategic & International Studies. She joins host Sylvia Leyva Martinez, a principal analyst covering global energy markets at Wood Mackenzie, to find out what the outlook is for US energy innovation. Escalating tariff policy is shaking investor confidence, altering supply chains, and putting the power firmly with China.Plus, in the second half of the…

“If you don't think in 15 years that we're going to value decarbonisation, or if you're worried about the 45Q, it's pretty tough to write that multi-billion dollar cheque,” says Peter Findlay, Director of CCUS Economics at Wood Mackenzie. In this week’s Interchange Recharged, Peter sits down again with host Sylvia Leyva Martinez to look at the challenges for new CCUS projects. It’s tough, as Peter says, because of the regulatory frameworks, financial mechanisms and incentives that currently exist in the US. To look at these and go deep on the legal barriers for CCUS deployment, Peter and Sylvia are also joined by Liz McGinley, partner at Bracewell Law Firm. Liz leads the firm’s tax practice and the energy transition team, and is renowned for her expertise in carbon capture and IRA tax credits. Liz discusses the intricate details of tax credits and regulatory updates while Peter reflects on the financial challenges of decarbonisation projects. In this episode:What will future legislative shifts mean for the…

The US is projected to add an additional 26 GW of solar capacity in 2025. Solar has been one of the energy transition’s biggest success stories, but there are dark clouds gathering. Uncertainty is the biggest barrier to deployment at the moment: there’s potential changes coming with federal tax credits and trade policies (some of which are already having an impact), and the perceived risks are high for investors of solar projects. To find out how developers and manufacturers are mitigating these risks, Sylvia Leyva Martinez, principal analyst covering solar markets at Wood Mackenzie, is joined by Mike Hall, CEO of Anza Renewables. Mike talks through the data he’s analysing; Anza is seeing supply chains diversify and financial incentives like the ITC Adder helping developers. Despite efforts to bolster domestic manufacturing, China continues to dominate the global solar market. What are the impacts of Trump’s tariffs on domestic manufacturing? With a quarter of the year already gone, what have we seen in…

In 2025, the US will consolidate its position as a blue-focused hydrogen market, driven by policy developments under a second Trump administration. A surge in blue hydrogen investment – with at least three large-scale blue hydrogen projects reaching FID – will see the US emerge as the world's leading blue hydrogen producer. So what about the much-hyped green hydrogen? Has the industry given up on it? To find out, host Sylvia Leyva Martinez, principal analyst at Wood Mackenzie, is joined by hydrogen analyst Bridget Van Dorsten. Bridget explains why, despite massive project announcements, only a fraction of hydrogen projects have actually moved forward. What are the biggest roadblocks to deployment? Already in 2025 we’re seeing financing hurdles, off-take uncertainty, and the challenges of scaling both green and blue hydrogen. To unpack the financial hurdles, Carl Cho - Director of Clean Energy Finance at Citibank – also joins the show. He breaks down the "hype cycle" surrounding hydrogen and why investors are…

Former President Biden's final days in office involved signing an US$840 million energy contract with Constellation - a statement of intent for the US’s largest nuclear supplier. Since then, what’s changed with nuclear policy? To find out, host Sylvia Leyva Martinez – a principal analyst at Wood Mackenzie – welcomes Maria Korsnick, President and CEO of the Nuclear Energy Institute to the show. Maria says that despite uncertainties, there's no reason large reactors couldn't achieve costs as low as US$60 to US$80 per megawatt-hour. Utilities are eyeing an additional 100GW of nuclear power by 2050 – driven in large part by demand from data centers and the tech giants. So how is the industry going to meet this demand? New technology? More permitting reform? More investment? Join us as Maria reveals the industry's strategic momentum and the pivotal role nuclear plays in providing round-the-clock, highly reliable and cleaner energy. Engagement with both state and tech sectors could shift nuclear from perceived…
