Basic introduction of solar hydrogen production

Solar hydrogen production system includes photolysis hydrogen production, solar power generation and electrolytic water combined hydrogen production system.

In traditional hydrogen production methods, the hydrogen produced by fossil fuels accounts for more than 90% of the world's total. Hydrogen production from fossil fuels mainly uses steam reforming and pressure swing adsorption to produce high purity hydrogen. Hydrogen production from electric energy electrolysis of water also accounts for a certain proportion. Hydrogen production from solar energy has been developed in recent 30 ~ 40 years. So far, the research on solar hydrogen production mainly focuses on the following technologies: thermochemical hydrogen production, photoelectrochemical decomposition hydrogen production, photocatalytic hydrogen production, artificial photosynthesis hydrogen production and biological hydrogen production.
