However, homogeneous catalysts are becoming more popular in the generation of H 2 for hydrogen storage, delivery, and in mobile/on‐site or small volume hydrogen applications. Generally for these applications, the H 2 gas produced should be pure (eg, no CO contamination), the hydrogen generation should take place under mild conditions, and the H 2 supply unit should be small. Most notably, research into homogeneous catalysis has focused on the chemical storage/delivery systems, based on sodium borohydride, ammonia‐borane, hydrocarbons/alcohols, and formic acid. In the HCOOHCO 2 , cycle the greenhouse carbon dioxide gas is used as the hydrogen vector. The use of solar energy in homogeneous catalytic H 2 gas production from water and from other hydrogen sources is the subject of extensive studies. A direct photochemical process converts solar energy into hydrogen much more efficiently than the two‐step electricity–water electrolysis/H 2 gas route.Read More
