More than 300 delegates from across Ireland’s renewable energy, agriculture and industrial sectors gathered yesterday (Wednesday, June 24) for the second annual Biomethane Day Ireland.

The event highlighted the growing momentum behind biomethane as a key pillar of Ireland’s energy transition and climate ambitions.

The conference, held in Dublin, brought together farmers, project developers, technology providers, contractors, energy off-takers, large energy users, policymakers, investors and industry experts.

Minister for Climate, Environment and Energy, Darragh O’Brien, who opened the conference, reflected on the increasing recognition of biomethane’s role in strengthening energy security, reducing emissions, and supporting rural economic development.

Biomethane interests

Biomethane Day Ireland 2026 provided a forum for discussion, collaboration and knowledge-sharing as Ireland seeks to accelerate the development of an indigenous renewable gas industry capable of contributing to national decarbonisation targets.

Delegates participated in a series of expert panel discussions covering:

Regulation, permitting and health and safety standards in biomethane projects;
Feedstocks and environmental performance;
Technologies driving biomethane production and upgrading;
Construction and development from a developer’s perspective.

The sessions provided a comprehensive overview of the opportunities, challenges and innovations shaping the future of biomethane in Ireland.

Minister O'Brien said: “Biomethane has a critical role to play in helping Ireland achieve its climate and energy objectives.

“Biomethane Day Ireland provides an important forum for industry, policymakers, farmers and energy users to come together to share knowledge, showcase innovation and accelerate progress in this vital sector.

"The development of a strong biomethane industry will be critical to delivering a cleaner, more resilient energy system while supporting sustainable growth and job creation."

The minister outlined to the attendees that a Renewable Heat Obligation (RHO) scheme is expected to be published soon.

This would legally mandate that fossil fuel suppliers provide a minimum quota of renewable energy (starting at 1.5%) for the heating sector.

In a keynote address later in the conference, Tom O’Brien, group CEO of Nephin Energy, highlighted the growing confidence emerging across the sector.

He said: “The strong attendance today reflects the clear appetite across Ireland’s biomethane sector for collaboration, investment and delivery.

"We are now at a pivotal stage in the industry’s development, and events like Biomethane Day play an important role in bringing stakeholders together to share expertise, build partnerships and accelerate progress.

"The case for biomethane in Ireland has never been clearer — it can help solve some of our biggest environmental and energy challenges. What matters now is turning policy into projects and ambition into delivery.”

Biomethane opportunity for farmers and climate

Interest in biomethane continues to grow as Ireland works towards its renewable energy and emissions reduction targets.

Farmers, developers, investors and industrial energy users are exploring opportunities within the sector.

They want to see the potential for the sector be a secure, indigenous and sustainable source of renewable energy, while also supporting rural economies and delivering long-term value.

Sector growth is being driven by a combination of evolving policy frameworks, rising demand for renewable energy, increasing investor confidence and a growing pipeline of projects nationwide.

As Ireland seeks practical solutions to decarbonise heat, transport and industry, organisers of the conference have stated that biomethane is increasingly recognised as one of the most scalable and cost-effective renewable energy options available.
