Climate Glossary

Biogas

a “green” gas produced by the decomposition of organic matter in an oxygen-free environment. Before it can be used as a fuel in vehicles, biogas must be refined to remove certain elements (carbon dioxide, water vapor and hydrogen sulphide), resulting in biomethane, which is nearly identical to NGV.

Biomass

The energy stored in biomass can produce electricity, using the heat from the combustion or fermentation of matter such as wood, plants, agricultural residues and organic waste.
