Biogas, Biomethane & Biohydrogen

Biogas is created when bacteria break down organic materials (plant and animal products) in an oxygen-free environment, a process known as anaerobic digestion. Biogas systems recycle organic waste through anaerobic digestion, resulting in biogas, which contains both energy (gas) and useful soil products (liquids and solids). Biogas is a renewable energy source that is environmentally friendly. It can occur naturally or be created as part of an industrial process to produce biogas for use as a fuel.

Biomethane (biogas) is one of the most popular applications for converting and using agrowaste for clean energy and biofuel production. Biomethane (also known as "renewable natural gas") is a near-pure methane produced either by "upgrading" biogas (a procedure that removes any CO2 and other pollutants present in the biogas) or by gasification and methanation of solid biomass. Biomethane is a versatile and easily storable fuel that may be utilized wherever natural gas is used without requiring any adjustments to natural gas-powered equipment.

H₂ that is created physiologically is known as biohydrogen. Biohydrogen is a carbon-free and environmentally friendly fuel. The burning of water produces it chemically. It has a wide range of applications, ranging from transportation to electricity generation.
