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.
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.
