Green Gas – Facilitating a future green gas grid through the production of renewable gas

Apr 2018

Green gas refers to renewable gas, which is currently mostly generated from the anaerobic digestion of organic biomass and residues produced in agriculture, food production and waste processing. Future technologies such as gasification+methanation and power to gas systems have been identified as methods that could also contribute substantially to renewable gas production.

This Task 37 report outlines the various substrates and technologies for green gas production and examines how much natural gas can be replaced by green gas in specific countries. An indigenous biomethane resource can potentially replace significant amounts of natural gas. Particularly in countries with well-established and closely linked gas grids, there are good opportunities to create a market for biomethane, thus lowering dependency on fossil fuels.
