Biological Hydrogen Production

  BIOLOGICAL HYDROGEN PRODUCTION 1. Introduction to Biological Hydrogen Production Biological hydrogen production involves the generation of hydrogen gas (H₂) through biological processes, primarily using microorganisms. This method is part of the broader conversation surrounding renewable energy technologies aimed at reducing reliance on fossil fuels and combating climate change. 2. Methods of Biological Hydrogen Production 2.1. Dark Fermentation Ø   Process Overview : Dark fermentation occurs in anaerobic conditions, where microorganisms such as certain Clostridium species break down organic materials to produce hydrogen. Ø   Substrates : Common substrates include glucose, starch, and lignin cellulosic materials, which can be derived from agricultural residues. Ø   Biological Mechanism : The process involves complex metabolic pathways, primarily glycolysis followed by the conversion of pyruvate into hydrogen and other products. Ø   Hydrogen Y...
