Direct solar hydrogen production has long promised a simpler pathway to renewable hydrogen by eliminating unnecessary energy conversion steps. While most commercial green hydrogen projects rely on photovoltaic electricity feeding standalone electrolyzers, researchers at the Fraunhofer Institute for Solar Energy Systems (ISE) have demonstrated a laboratory scale integrated system that converts sunlight into hydrogen with a solar to hydrogen efficiency of up to 31.3%, placing it among the highest reported performances for direct photoelectrochemical hydrogen production.
