SEAI: Ireland Needs Fossil Fuel Boiler Phase-Out by 2035 for Decarbonization

Ireland must establish a deadline for ending new gas and oil boiler installations to decarbonize heating, according to the Sustainable Energy Authority of Ireland (SEAI). Margie McCarthy, SEAI director of research, stated that a phase-out, not necessarily a ban, is needed, emphasizing that affordable alternatives would drive adoption.

The SEAI published a paper outlining how Ireland can nearly fully decarbonize its heating and cooling sector for homes and businesses by 2055. Heating currently accounts for 90% of fossil fuel dependence and a quarter of the country’s greenhouse gas emissions. The paper’s modeling for full decarbonization by 2055 assumed no new fossil fuel boilers for industries after 2030 and for homeowners after 2035.

Such deadlines require financial supports, clear timelines, and affordable alternatives to ensure a fair transition. Delaying the phase-out increases costs, emissions, and fossil fuel lock-in, as new boilers last 15-20 years. The SEAI also highlighted the need to improve energy efficiency, reduce heating demand, and rapidly scale district heating, which is currently limited to one scheme in Tallaght, Dublin.

Decarbonizing heat will save Ireland money long-term but involves upfront investment and ongoing energy costs. Grants, tax incentives, and electricity price reforms are crucial to support consumers, as high electricity prices are a major barrier to heat pump adoption. New policies are essential to avoid continued heavy reliance on fossil fuels and enhance energy security, especially given global energy price volatility.
