Ireland has committed to producing up to 5.7 TWh of indigenously sourced biomethane per annum by 2030.
The National Biomethane Strategy, published in May 2024, sets out the policy framework for an agri-led biomethane sector. Gas Networks Ireland estimates that meeting the target will require up to 150–200 new anaerobic digestion plants. As of early 2026, Ireland has two operational facilities injecting biomethane to the national gas grid, producing approximately 75 GWh per year, less than 1.5% of the 2030 target.
The legislative architecture is taking shape. The Renewable Heat Obligation Bill 2025, which will underpin the RHO scheme from mid-2026, has completed priority drafting and is subject to EU TRIS notification, with the standstill period concluding on 30 March 2026. The Sectoral Capital Plan 2026–2030 allocates €100m–€200m in capital funding for biomethane from the Infrastructure Climate and Nature Fund.
