Forget cars, what does the transition to electric FREIGHT look like? How capable are HEAVY electric vehicles? What’s the future for shippers, logistics companies and charging infrastructure? I travel to Cambridge to ask David Cebon, a visionary in ...

Can carbon pricing incentivize a sustainable future? What lessons have early-movers learned? How to neutralize the politics? How will the EU’s Carbon Border Adjustment Mechanism shape our future? Prof. Cameron Hepburn answers these questions and more …

For 41 of the past 49 days, the fifth largest economy in the world has met >100% of electricity demand using solar, wind and hydro generation, frequently exceeding 140% of demand. What lessons can be learned? What does this tell us about future of energy? I asked Prof. Mark Jacobson, the most respected renewables voice on the planet …

What will the global energy mix look like in 2060? Which technologies will dominate in future, and which will dead-end? What about the toughest problems, like powering long range ships and aircraft? What happens to nuclear? I asked Michael Barnard, consultant to the biggest energy investors on the planet ...

If we allocated EIGHT TIMES all the renewable energy in the world to Direct Air Carbon capture (DAC), we still WOULDN’T REDUCE CO2 BY A SINGLE MOLECULE; we would ONLY just be keeping up with new emissions …

I love hydrogen. It burns clean. It can power long-distance trucks and ferries. It offers long-haul aviation a pathway towards a (nearly) net-zero future, and it gives us a way to make our steel without burning all that coking coal. But lovely hydrogen can only ever be a SMALL part of our future. Here’s why …

Has Martin Green done more than any other human to safeguard our future? For 50 years he has pushed the cost/efficiency boundaries of solar cells, setting world record after world record, and his technology is now imbedded in 91 percent of worldwide solar module production. Who better to sit down with to explore the myriad ways we will extend the solar contribution to our future ...

BRUCE MCCABE: So it's just at the commercial level we're sitting at 20% ? MARTIN GREEN: That’s right, yes. We hold the record for overall conversion of sunlight at 41%. It's proving difficult to translate that into a low-cost device, but I think eventually we'll be successful. So we have the potential for essentially doubling the efficiency …

The critical question about fusion is no longer, Will it work? but rather, Can we make a fusion power station that produces commercially-competitive electricity? And secondarily, assuming the answer to the above is ‘yes,’ then when is the earliest fusion could significantly impact the global energy system? I asked Alex Creely, the Head of Tokamak Operations at Commonwealth Fusion Systems, how things were progressing …

What comes after Lithium-ion? It’s one of the most important technology questions in the world! Everything in the future of electronics, road vehicles, renewables, distributed storage on the electricity grid and even the future of commercial aviation hinges on the answer. I visited Dr George Crabtree, Director of the Joint Center for Energy Storage Research (JCESR) at Argonne National Laboratory to find out …

George Crabtree: By 2030, the market and the sales of EVs will go up by a factor of ten, which is huge. So all experts agree there is enough lithium in the earth's crust to handle a global exclusive EV market. The question is, can you get it out fast enough? If demand goes up by a factor of ten in ten years …

I asked someone who was flying one. The person who made me think differently about electric aviation was an engineer by the name of Joshua Portlock. I had big lingering doubts about the battery/weight compromises, but here was this guy making noise about the subject, trying to get approvals to set up a commercial sightseeing service …
