This document discusses the potential for renewable gas, specifically biomethane, in Ireland. It notes Ireland's renewable energy targets and outlines how biomethane could help meet targets for electricity, heating, and transport. The document examines biomethane production from various feedstocks like agricultural waste and surplus grass. It provides examples of biomethane production facilities in other parts of Europe and estimates Ireland has the potential to produce over 400 million cubic meters of biomethane annually. The document also discusses the costs of producing biomethane and maps out the potential from grass biomethane in the Ballyhoura region of Ireland.
