Solar-to-Hydrogen
Clean, renewable hydrogen can be produced by splitting water into hydrogen through an electrolyzer powered by solar energy. But a potentially cheaper and more efficient way to do this is to use photoelectrochemical (PEC) cells, which convert sunlight and water directly into hydrogen right there at the cell.

Hydrogen City will eventually harness 60 gigawatts of solar and wind energy, and use it to produce over 2.5 billion kilograms of green hydrogen a year, keeping it underground in storage caverns at the Piedras Pintas salt dome before transport. -
Western Australia could soon be home to the world's biggest green hydrogen project. The Western Green Energy Hub wants to deploy 50 GW of solar and wind generation to produce up to 3.5 million tons of green hydrogen or 20 million tons of ammonia a year.

Well-respected Austrian solar energy company Fronius has broken ground on its first customer green hydrogen hub, giving us a good look at what it'll take to run a fleet of vehicles on green hydrogen produced entirely on-site using solar panels.
-
Germany's Svevind has announced plans for a colossal green hydrogen project that will place some 45 gigawatts of wind and solar energy generation on the vast steppes of Kazakhstan to produce around three million tonnes of green hydrogen annually.
-
A new project in the Australian Outback will trial an innovative technique for converting solar energy into hydrogen by capturing moisture from the air and splitting it via hydrolysis, making it possible for hot, arid areas to become energy exporters.
-
Australian company Lavo has debuted a hydrogen production, storage and conversion system for the home. It stores up to two days' worth of energy from your rooftop solar – and should outlast a lithium battery by many years. So what's the catch?
-
Solar-to-hydrogen cells can convert solar energy directly into hydrogen without needing an external electrolyzer, and an exciting new design out of the Australian National University has achieved record efficiency levels using low-cost materials.
