This research paper entitles the research work regarding bio-hydrogen generation from a renewable source, namely biomass; such as a group of photosynthetic microorganisms cyanobacteria. Molecular hydrogen is widely regarded as the energy carrier of the future. It can be used in fuel cells, generating an electric current. Biohydrogen production has several advantages when compared to photoelectrochemical or thermo-chemical processes due to the low energy requirement and  investment cost. Cyanobacteria has an inherent ability to produce molecular hydrogen via the enzyme complex nitrogenase. This hydrogen is not released, however but is recaptured by the bacteria using an uptake hydrogenase. The study also foretells about optimization of the various key parameters that enhance hydrogen production. This knowledge can be used to evaluate the possibilities for producing hydrogen and high value products efficiently in the same process.

The drift theory of fossil fuel production is associated with the plant material transported with stream of water from one place to another, and finally get deposited in a place of swamp having the suitable condition like sediments. The evidence of drift theory is provided by the sedimentary deposits of coal and other fossil fuels. To trace the origin of formation of fossil fuels in the earth’s crust, we consider the application of laws of thermodynamics using the Hess’s Law, Gibb’s free energy, heat enthalpies, and particularly the deoxygenation parameters to study the transformation of plant materials into the fossil fuels. Here, I elucidate the concept of thermodynamics linked intricately with the development of fossil fuels and the phenomena of photosynthesis, a prerequisite in the thermal analysis of fossils.
