Hydrogen is one of well-known clean energy source.
Several technologies are already available in the marketplace for the industrial production of hydrogen.
Hydrogen can be produced from a variety of feedstocks.
A variety of process technologi
production costs. The main technical issues for these high-temperature processes relate to materials development for corrosion resistance at high temperatures, high-temperature
membrane and separation processes, heat exchangers, and heat storage media. Design aspects and safety are also important for high-temperature processes.

1. Uptake Hydrogenase
1) Definition of Uptake Hydrogenase and Mechanism of Hydrogen Production
Uptake hydrogenases are Ni-Fe enzymes that catalyze the conversion of hydrogen gas to hydrogen ions and electrons. They are found in the heterocysts and not in the vegetative cells of nitrogen-fixing strains of cyanobacteria. They remove the hydrogen gas produced by nitrogenase when they carry o
