Clean energy, climate tech and the technology decarbonising industry.
Green hydrogen is often billed as a clean fuel for everything, but the energy losses involved in making and using it mean it will likely end up reserved for the jobs electricity cannot easily do.
As wind and solar supply more of Britain's electricity, storing energy for hours or days at a time is becoming as important as generating it in the first place.
Small modular reactors promise cheaper, faster nuclear power built in factories rather than on site, but the technology still has significant hurdles to clear before it can deliver on that promise.
