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.

EPFL engineers have built and tested a solar reactor that generates hydrogen gas from sunlight and water. The system is not only highly efficient at producing hydrogen, it also captures the “waste” products of oxygen and heat to put them to use too. -
UMich researchers have demonstrated an artificial photosynthesis device 10 times more efficient and one hundredth the size of previous devices of its kind. This green hydrogen production method also improves over time, and can split seawater. -
Hydrogen supercar maker Hyperion isn't happy about the state of hydrogen fuel infrastructure, so it's decided to start building its own, rolling out yacht-styled mobile hydrogen stations across the United States that can generate fuel on-site. -
Sesame Solar announced this week what it calls the world's first 100-percent renewable mobile nanogrid. Powered by a wing-like solar panel spread and green hydrogen, the modular nanogrid brings weeks of autonomous electricity where it's most needed. -
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.
