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
hydrogen energy, tidal energy and so on are researched with activity by scientists. Among them, hydrogen energy system supremely comes into the spotlight. Hydrogen energy system bases an ideal principle which hydrogen is produced from water and returns to the original substance; water after being used. We can expect that after 2010, the cost of hydrogen as one of the resources should be lower th
