The fastest path to more power: How advanced conductors could unlock grid capacity without new transmission

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 generat

Speed to power: Why data-center load growth is creating a new opening for C&I solar, storage, and microgrids

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 generat

Thorium’s nuclear pitch: Can molten salt reactors cut cost, use waste, and scale faster than conventional designs?

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 sup

The inverter security turn: How Europe and the US are redrawing solar procurement around Chinese hardware

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

Why biomining might finally work: How Endolith is using microbes and data to unlock more copper from low-grade ore

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

Bigger turbines, bigger consequences: how wind is rethinking risk, insurance, and predictive maintenance

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, al

As racks scale, power must change: The AC-to-DC rethink inside AI factories

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 allo

Handing back the mic: Six months of data center reality, from Bragawatts to behind-the-meter, and the questions still open

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 announ

The grid's missing operating system: Why a $100,000 AI controller could defer trillions in hardware and why utilities won't buy it

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

The grid's immune system is retiring: Synchronous condensers, AI data centers and the physics gap that software alone can't close

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

Beyond combustion: Long Island's first hydrogen-powered linear generator and the fuel-flexible answer to the dispatchable emissions-free resource problem

Utilities are under pressure to deliver generation that is dispatchable, affordable, and clean enough to satisfy increasingly stringent environmental rules, notoriously h

The electrolyzer reckoning: Can disciplined product development deliver on green hydrogen's promise before the survivors run out of runway?

Empty gigawatt factories, product recalls, participation rates that never materialised, and a policy environment that has now stripped the green premium entirely. The ele

Flexibility as a service: Can Octopus's acquisition of Uplight finally make US residential VPPs work?

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

The muscle we forgot: SMRs, hyperscalers, and why this nuclear renaissance might actually be different

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

The grid nobody planned for: public power, hyperscalers and the race to rewire America for the AI age

What two decades of flat demand means for a grid now expected to double in size The US went from essentially zero load growth for twenty years to 3% national growth almo

Is hyperscaler demand finally giving CCS its moment?

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, t

Building the plane while it’s flying: data centers, utilities, and the new rules of power

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 thi

Fuel cells are powering AI data center demand: they’ve moved from interesting clean tech to major player. How are utilities using them?

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 loo

AI, and the battle for energy in 2026. What clean energy sources are going to meet demand?

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,

How are key renewable energies faring at the end of 2025? Guest host and energy analyst Bridget van Dorsten talks through developments in geothermal, hydrogen and wind.

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 h
