Hydrogen (H 2 ) produced from renewables will have a
growing impact on the global energy dynamics towards sustainable
and carbon-neutral standards. The share of green H 2 is still too low to
meet the net-zero target, while the demand for high-quality hydrogen
continues to rise. These factors amplify the need for economically
viable H 2 generation technologies. The present article aims at
evaluating the existing technologies for high-quality H 2 production
based on solar energy. Technologies such as water electrolysis,
photoelectrochemical and solar thermochemical water splitting, liquid
metal reactors and plasma conversion utilize solar power directly or
indirectly (as carbon-neutral electrons) and are reviewed from the
prospective of their current development level, technical limitations
and future potential.
