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 detailed opinion from the Commission does not necessarily end the legislation, but it typically requires the notifying state to respond and may delay implementation.
That means the industry will now be watching for four key signals:
- whether the Government proceeds with publication before summer recess
- whether biomethane support is redesigned outside the RHO
- whether obligation rates for liquid fuels are increased
- whether separate compliance routes emerge for gas and liquid heating fuels
Why it matters
For Irish distributors and suppliers serving oil-heated homes, the final shape of the RHO could directly influence future product demand, blending requirements, customer pricing and investment decisions.
If obligation rates remain modest, market change may be gradual. If rates are strengthened, or if a dedicated renewable liquid fuel mechanism emerges, suppliers may face faster transition timelines but also clearer commercial opportunities.
Either way, the Commission’s intervention appears to have turned the focus back to how effective and workable the RHO will be in practice.
