Assessing the potential of hydrogen in decarbonising residential heating in Ireland

Ireland has an ambitious vision to reach net zero by 2050, and decarbonising residential heating is a significant challenge. This report examines the potential for hydrogen-based heating solutions in decarbonising residential heating in Ireland.
On comparing the various options of using hydrogen for domestic heating in Ireland, hydrogen blending in the gas network is likely the most effective solution. It provides a non-disruptive solution to the consumers and yields substantial CO2 savings.
Based on our analysis, we estimate ~1 TWh of hydrogen demand annually to supply 20% hydrogen blended gas to the domestic sector. Other hydrogen heating solutions, although technically feasible, are restricted by connectivity to the gas network and the availability of more efficient heating solutions such as heat pumps.
