AD Plants Supply Biomethane To Green Gas Facility


A number of third-party anaerobic digestion (AD) plants in Ireland have agreed to supply biomethane to a central grid injection (CGI) facility.

The building of the country’s first large-scale green gas site, developed by Gas Networks Ireland (GNI), will start in summer 2023. However, the €30 million (£25.5 million) Green Renewable Agricultural Zero Emissions project, known as GRAZE, does not include AD facilities.

Therefore, GNI has revealed these will be operated by 20 third parties, with farmers and private investors supplying biomethane – a renewable gas created through AD from farm and food waste – to the facility in Mitchelstown, County Cork.

Minister for the environment, climate and communications Eamon Ryan TD stated: “Projects such as this will reduce our reliance on imported fossil fuels, which is especially important now in the context of the war in Ukraine.”

“It will contribute to our broader climate goals – of cutting greenhouse gas emissions by 51 per cent by 2030 and reaching net zero emissions by 2050,” it was added.

According to GNI, farmers will benefit, as they will be able to earn money from the sale of biomethane, the organic bio-fertiliser, crops, feedstocks, and waste.

What’s more, they will be able to reduce their carbon footprint by replacing chemical fertilisers with biofertilizer digestate. They will also displace the emissions from waste and slurry with the AD process.

As a result, GRAZE has been very popular among farmers and producers, with GNI having received more than 130 enquiries to date. However, there have not been any contracts signed as of yet, Bioenergy News reported.
