Hydrogen is a promising, renewable fuel for the future as it does not produce the "greenhouse gas" CO2 & it also liberates large amounts of energy, per unit weight, in combustion. Further it is easily converted into electricity by fuel cells.

Biological hydrogen production has several advantages over conventional hydrogen production, whether that is a photo electrochemical, or thermo chemical process. Currently hydrogen is produced using ‘non renewable’ technologies such as the steam reformation of natural gas (~50% of global H2 supply), petroleum refining (~30%) or the gasification of coal (~20%).

However, under certain conditions, instead of reducing CO2, a few groups of microalgae and Cyanobacteria consumes biochemical energy to produce molecular hydrogen. The enzymes hydrogenase and nitrogenase, are capable of producing hydrogen within microbes.

|
This algal hydrogen production is being developed as an economical and sustainable method of bio hydrogen production by water utilisation as a renewable resource and CO2 consumption as an air pollutant. However, the viability of the future H2 economy depends entirely upon the development of efficient, large-scale and sustainable H2 production systems.

At Hash BioTech we have developed improved strains of microalgae capable of producing large volumes of hydrogen at the expense of air, light and water. Efforts are under way to optimize the photo evolution of hydrogen by using the appropriate system of photobioreactor.
