Green hydrogen production (electrolysis powered by renewables)

The world needs to replace fossil fuels with clean energy sources fast — but we're not moving nearly quickly enough. Even as solar and wind costs have plummeted, we're still adding more fossil fuel capacity than clean energy in many regions. The challenge isn't just building more renewable power plants. It's also storing that energy when the sun isn't shining, upgrading ancient electrical grids, speeding up painfully slow permitting processes, and dealing with the reality that we've already built trillions of dollars worth of coal and gas infrastructure that someone paid for and expects to keep running.

Meanwhile, nearly a billion people still lack electricity entirely, and even in wealthy countries, our energy systems are rigid and wasteful. We need technology solutions that make clean energy cheaper, faster to deploy, and more reliable than fossil fuels — not just sometimes, but always.

Solar panels don't work at night, and wind doesn't blow on schedule. But people need electricity 24/7, and demand peaks in the evening when solar output is dropping. Without storage, this mismatch forces utilities to keep fossil fuel plants running as backup, undermining the climate benefits of renewables.

Solving this requires technologies that can store massive amounts of energy for hours, days, or even seasons — and release it exactly when needed.

Using excess renewable electricity to split water into hydrogen and oxygen. The hydrogen can be stored for months and later converted back to electricity, used directly as fuel for industry and transportation, or converted into other clean fuels. This could solve seasonal storage challenges and decarbonize sectors that are hard to electrify directly.
