    Grid Congestion Is Holding Back Business. Virtual Power Plants Could Help

    Get in touch - leave me a message

    Grid congestion is no longer just a utility headache. In places such as the Netherlands, it can obstruct business expansion just as AI data centres add pressure to electricity networks.

    I speak with Marco Krapels, Senior Vice President and CMO at Enphase Energy, about a counterintuitive idea: homes equipped with solar, batteries and bidirectional EV charging could help provide the grid flexibility businesses increasingly need.

    We explore what would make these virtual power plants dependable enough for utilities to trust, why stored energy is not the same as guaranteed capacity, and whether more efficient data centres actually mean lower emissions. The engineering matters. So do the incentives and regulations.

    Listen now to discover what could ease grid congestion, what could stop it working, and why energy flexibility belongs in business infrastructure planning.

    The Island Power Trap: Expensive Diesel and the Renewable Finance Gap

    Get in touch - leave me a message

    Caribbean islands pay a steep price for electricity generated from imported diesel. Solar and storage offer an alternative, but cheaper technology alone won't overcome the financing barriers keeping projects and households out.

    I speak with David Gumbs, Director of RMI's Global Islands Programme and former CEO of Anguilla's electricity utility, about what volatile fuel costs mean for businesses, government budgets and energy security.

    Why can promising renewable projects struggle to attract investors simply because an island is small? We examine Grenada's approach to project finance, community-funded solar in the Dominican Republic, and the difference between clean power and hurricane-resilient power. Kismet: isolated island grids can expose integration challenges that larger electricity networks have more room to absorb.

    Listen now to understand which financing, policy and grid decisions could turn abundant renewable resources into affordable, reliable island electricity.

    The Lithium Isotope Bottleneck Between Nuclear Breakthroughs and Power Plants

    Get in touch - leave me a message

    Advanced nuclear could have a lithium isotope problem long before it has a commercial power plant. Promising reactor designs need specialist materials that are barely produced at industrial scale.

    John Elling, CEO of Molten Salt Solutions, joins me to explain why isotope separation matters to both advanced fission and fusion. Getting enough of the right lithium, at a price developers can plan around, is an engineering and investment challenge - not simply a procurement exercise.

    We explore the surprising reason some fission reactors want to avoid lithium-6 while many fusion designs depend on it. We also examine how material prices can change reactor design, and the dilemma facing suppliers asked to invest in production capacity before customers can commit to buying it.

    Listen now to understand what needs to happen between a nuclear breakthrough and a power plant delivering electricity to the grid.

    AI’s Power Boom Could Pull Factory-Built Nuclear Down the Cost Curve

    Get in touch - leave me a message

    AI data centres are creating an extraordinary new demand for electricity. The harder question is whether clean, firm power can be built quickly enough to meet it, without falling back on gas.

    My guest in this episode is Matt Loszak, co-founder and CEO of Aalo Atomics, which is developing small, factory-built nuclear reactors initially for AI data centres. The bet is that nuclear can move from bespoke megaprojects to repeatable manufactured products, cutting deployment time while preserving the reliability these facilities require.

    We examine what that shift would actually demand: why standardisation changes nuclear construction, why data centres may provide the high-paying early market needed to bring costs down, and why reaching criticality is very different from proving a commercially viable power plant. We also get into the harder engineering test - operating reliably at high capacity factor, and whether SMRs can scale without recreating the problems of conventional nuclear.

    Listen now to hear what factory-built nuclear still has to prove, and why AI’s appetite for power may give it an unusually significant opportunity to do so.

    Enhanced Rock Weathering’s Scaling Bottleneck Is Proof, Not Rock

    Get in touch - leave me a message

    Enhanced rock weathering looks deceptively simple: crush suitable rock, spread it on farmland and let chemistry remove CO₂. The harder question is whether you can prove that removal reliably enough to make the economics work.

    I speak with Chris Zair, Director of Partnerships at UNDO, about what happens when enhanced rock weathering moves from controlled trials into real fields. For buyers, investors and policymakers, the stakes are practical: measurement and verification can account for roughly half the cost stack, and weak data can stop credible carbon removal from becoming financeable infrastructure.

    We look at why disappearing rock creates an unusual MRV problem, what changes when carbon-credit contracts pay only on delivery, and why having plenty of rock and farmland still does not guarantee scale. We also examine the trade-off between durability, cost and speed - including why particle size can radically alter how quickly CO₂ is removed.

    Listen now to understand what is really holding back enhanced rock weathering - and what has to change for carbon removal to become measurable, financeable and repeatable at scale.

    The 15-Litre Engine Opens Heavy-Duty Trucking to RNG—Economics Decide What Scales

    Get in touch - leave me a message

    For years, renewable natural gas had a basic problem in heavy-duty trucking: it lacked a 15-litre engine capable of doing the work fleets expect from diesel. That barrier is disappearing. The harder question now is whether the economics and infrastructure stack up.

    My guest is Scott Brinner, Executive Vice President of RNG Solutions at NoPetro Energy, who works across RNG production, fuelling and fleet deployment. We look at the real decision facing operators: can fuel savings overcome a $70,000–$90,000 truck premium without creating new operational risk?

    We examine why high-mileage, return-to-base fleets may be the strongest early fit, what fuelling and maintenance infrastructure can quietly derail adoption, and why the climate case depends on feedstock, methane leakage and lifecycle accounting—not the label on the pump. We also test where RNG belongs alongside battery-electric trucking rather than treating every route as the same problem.

    Listen now to understand where renewable natural gas can genuinely work in heavy-duty trucking—and what fleets need to prove before scaling it.

    Carbon Removal’s Real Bottleneck Isn’t Technology. It’s Demand.

    Get in touch - leave me a message

    Carbon removal is often framed as a technology problem. But what if the harder constraint is demand, and what if waiting decades to remove a tonne of CO₂ carries a climate cost of its own?

    My guest is Barclay Rogers, founder and CEO of Graphyte, a durable carbon removal company using agricultural and timber residues in a process it calls Carbon Casting. He brings a practical operator’s view of what it takes to move carbon removal from credible tonnes to meaningful scale.

    We examine the “time value of carbon”, challenge the assumption that removals should wait until every possible emissions cut has been exhausted, and look at what really constrains scale once the underlying process works. We also get into measurement and verification, project finance, community acceptance, wildfire mitigation, and the uncomfortable question of where biomass carbon removal stops making sense.

    Listen now to understand what could turn durable carbon removal from an emerging market into infrastructure — and what still stands in the way.

    Generation Is Not Delivery: The Grid Problem Behind Decarbonisation

    Get in touch - leave me a message

    Building more renewable generation is not enough if the grid cannot carry the electricity to where it is needed. Curtailment, connection queues and delayed infrastructure are turning grid capacity into a climate and competitiveness constraint.

    My guest today is Niklas Persson, CEO of Grid Integration at Hitachi Energy, with nearly three decades in electrification. We look at what happens as industry, transport and data centres demand more clean power while transmission infrastructure, permitting and grid connections struggle to keep pace.

    We examine why the grid may need to arrive before demand is certain, how interconnectors can reduce the cost of resilience, and whether energy independence could actually require greater cross-border interdependence. We also explore HVDC, the 600 MW ELMED link between Tunisia and Italy, and a harder policy question: when grid capacity is scarce, who should get connected first?

    Listen now to understand why electricity generation is only half the decarbonisation challenge, and what has to change if clean power is actually going to reach the businesses, vehicles and communities that need it.

    Solar, Batteries and EVs Are Turning Delay Into an Investment Risk

    Get in touch - leave me a message

    Solar, batteries and EVs are moving fast enough to change the risk calculus for energy investment. The bigger mistake may now be assuming today’s system, and its customers, will still be there tomorrow.

    I speak with Professor Ray Wills, Managing Director of Future Smart Strategies, who has been modelling technology adoption curves for years. We examine what accelerating clean-energy deployment means for capital allocation, electricity prices, new gas infrastructure and industrial competitiveness.

    We look at how batteries can reshape power-market economics before they dominate annual generation, why conventional forecasts may struggle with nonlinear adoption, and what China’s scale in solar, batteries and EVs tells Western leaders about where competitive advantage is moving. The harder question is no longer simply how fast these technologies can grow, but how costly it becomes to plan as though they won’t.

    Listen now to understand how rapidly changing energy economics could alter the investment decisions businesses and policymakers are making today.

    Long-Duration Energy Storage Is Ready. The Energy Markets Aren’t

    Get in touch - leave me a message

    Long-duration energy storage is increasingly ready to deploy. The harder problem is that electricity markets still struggle to value what duration actually provides - flexibility, reliability and power when the sun sets, the wind drops and demand peaks.

    My guest is Julia Souder, CEO of the Long Duration Energy Storage Council. She works across the policy, finance and deployment questions shaping this market, and brings a useful view of what is already happening in places such as China, Australia, the UK, Ireland and the US.

    We look at why storage is becoming an infrastructure and investment question rather than simply a technology question; what changes when markets pay for four hours of capacity but the grid increasingly needs eight, 12 or 24; and why revenue certainty may now matter more than another technical breakthrough. We also examine what China appears to be getting right about deployment, and why long-duration storage matters for data centres, industrial heat and renewable-heavy grids.

    Listen now to understand what is really holding back long-duration energy storage at scale, and what could shift the economics, policy and investment case.

    Buyer Pressure Helped Avoid 2 Million Hectares of Deforestation

    Get in touch - leave me a message

    Two million hectares of avoided deforestation is not a theoretical climate benefit. It is what Priscillia Moulin says can happen when companies stop treating supply-chain risk as somebody else’s problem. ClimateEpisode291.srtSRT

    Priscillia is Director of Strategy at MosaiX, working on deforestation-free commodity supply chains across palm oil and other high-risk materials. Her work sits at the intersection of traceability, satellite monitoring, supplier engagement and EUDR — where corporate commitments have to survive contact with real plantations, real contracts and real communities.

    What struck me most was how much leverage buyers can have once they know where products actually come from. We look at why satellite data still needs human verification, how a confirmed deforestation case can sometimes be stopped within days, and why simply dropping a non-compliant supplier may protect a brand while doing very little for the forest. We also challenge the habit of reducing forests to carbon alone.

    Listen now to understand how traceability and commercial pressure can turn deforestation policy into measurable change on the ground.
