4 Biomethane Potential in Ireland

5 Policy Background Ireland s renewable energy sources (RES) target is 16% RES by Ireland s Greenhouse Gas (GHG) emissions target is 20% less CO 2 by 2020 relative to Road and rail transport contributes ~ 29% of non- ETS GHG emissions. Agriculture contributes ~ 46% non-ets GHG emissions. Fig.1 EPA non-ets GHG emissions forecast for 2020 Ireland is set to miss both RES and GHG 2020 targets. 5

6 Renewable Gas Potential in Ireland The Member States with the largest potential growth of biogas production between 2014 and 2030 are Ireland and Romania, (European Commission Report 1 ). 1 Kampman et al Optimal use of biogas from waste streams; An assessment of the potential of biogas from digestion in the EU beyond Available at: 6

7 Biogas Potential in Ireland Assessment of Costs and Benefits of Biogas and Biomethane; 28% of 2015 natural gas demand can be supplied from biogas. Additional grass is the largest bio-resource in Ireland (35 PJ). Levelised Cost Of Energy (LCOE) biomethane range ( /MWh) depending on feedstock, scale and discount rate. 7 SEAI, Assessment of Costs and Benefits of Biogas and Biomethane. Available at:

8 Gas Networks Ireland s Vision for Renewable Gas Reduce carbon footprint of network through development of Renewable Gas. 20% renewable gas on network by % renewable gas will deliver; 2 million tonnes less CO 2 p.a. 7.4% of Ireland s Final Energy Consumption. 200 million euro p.a. avoided energy imports.
