Solar hydrogen panels offer a method of capturing solar energy by producing green hydrogen that can be used in industrial and transportation applications. Solar hydrogen panels operate via photovoltaic−electrochemical (PV-EC) water splitting with two components: the photovoltaic cell and the electrochemical cell (or electrolyzer).
Green hydrogen production also has the potential to use excess electricity generated by solar and wind power, making it a complementary technology for these renewable sources. On the other hand, solar and wind energy are direct electricity producers and are more suitable for decentralized and residential applications.
Also in 2019, scientists at KU Leuven ’s Center for Surface Chemistry and Catalysis in Leuven, Belgium created a solar hydrogen panel which produced hydrogen with a 15% solar-to-hydrogen efficiency, a leap from their maximum efficiency of 0.1% a decade earlier. This 15% efficiency is also the current world record for solar hydrogen panels.
When installed alongside a solar thermal collector and traditional solar panels, hydrogen panels could help heat homes and provide electricity throughout the year. “The hydrogen panels themselves do not store hydrogen and work at very low pressure. This has several safety and cost benefits.
A solar hydrogen panel is a device for artificial photosynthesis that produces photohydrogen from sunlight and water. The panel uses electrochemical water splitting, where energy captured from solar panels powers water electrolysis, producing hydrogen and oxygen.
Hydrogen production relies on the presence of electrical power at the input of the electrolyzer, which is contingent upon the availability of solar radiation. To maximize the solar energy supplied to the load, the availability of solar radiation should match the PV generation.
Photocatalytic solar hydrogen production from water on a 100-m
Carbon-neutral hydrogen can be produced through photocatalytic water splitting, as demonstrated here with a 100-m2 array of panel reactors that reaches a maximum conversion efficiency of 0.76%.
