European Commission raises questions over Ireland’s Renewable Heat Obligation

Ireland’s proposed Renewable Heat Obligation (RHO) has faced a significant setback after the European Commission issued a detailed opinion challenging elements of the planned scheme – a move that could force revisions to one of the country’s flagship heat decarbonisation policies.

The intervention centres on proposals to include incentives, or multipliers, for domestically produced biomethane within the RHO framework. Following its scrutiny of the draft legislation, the Commission concluded the scheme cannot proceed in its current form with those measures included.

That matters because support for domestic biomethane is core to the proposed RHO and is positioned as a complementary mechanism to Ireland’s National Biomethane Strategy. The opinion therefore raises broader questions over how the obligation will be structured, how quickly it can be introduced, and whether policymakers may now need to revisit the combined fuel approach.

For the liquid fuels sector, the development is particularly relevant. The RHO is expected to play a central role in determining how renewable liquid fuels, such as HVO, can contribute to decarbonising Ireland’s large off-grid heating market.

Time for a rethink?

Philip Hannon, Chief executive of The Alliance for Zero Carbon Heating (TAZCH), believes the Government’s intention to publish the bill before the summer recess may now be in doubt, and suggested the Commission’s decision should trigger a more fundamental rethink of the scheme

“This news from the Commission must surely cast doubts on the bill and how it is constructed,” he said.

TAZCH has consistently argued that the currently proposed obligation rates of 1.5% and 3% are too low to stimulate meaningful additional renewable liquid fuel blending in the heating market. According to the alliance, low introductory rates risk creating compliance costs for suppliers and consumers without delivering proportionate carbon savings.

The group also renewed calls for a dedicated liquid fuels pathway within the wider framework, suggesting that a single blended approach may fail to reflect the practical realities of Ireland’s heating market.

Mr Hannon argued that in order for the 700,000 homes currently using kerosene, representing 40% of the home heating market, to benefit from the RHO, a minimum introductory obligation rate of 5% must be introduced. “The Government will have to rethink its proposals on biomethane as part of the RHO but should also take the opportunity to rethink obligation rates if it wants the key piece of environmental legislation to succeed. Included in this, should be consideration for a separate scheme for liquid fuels for which TAZCH has also strongly argued.

What happens next?

A European Commission intervention does not necessarily end Ireland’s Renewable Heat Obligation, but it does increase pressure on policymakers to rethink how the scheme is structured and delivered.

For installers, suppliers and homeowners, the key issue is certainty. Heating transitions work best when policy is clear, practical and trusted by consumers. Delays or redesigns can slow investment decisions, postpone upgrades and create confusion in the market.

Industry voices have argued that this moment should be used constructively. Rather than viewing it simply as a setback, it may be an opportunity to build a stronger framework that balances carbon reduction goals with affordability, fuel security and workable choices for households.

For the liquid fuel and heating sectors, that could mean renewed focus on blended renewable fuels, staged transitions and technology-neutral solutions that reflect the reality of Ireland’s diverse housing stock.

What happens next matters. If government responds with a more robust and better-balanced scheme, the current disruption could ultimately lead to a more durable pathway for decarbonising heat.
