Mayo village set for multi-million euro hydrogen and energy centre 

A transformative project in Killala has been strongly welcomed by Alan Dillon TD, Minister of State at the Department of the Environment, Climate and Energy.

Describing the development as a milestone for the region, Minister Dillon hailed the decision as a “significant moment for Killala and North Mayo,” and a critical move toward positioning Mayo as a national leader in renewable energy and green industry.

The project, set to include a 106MW Energy Centre and state-of-the-art Hydrogen Plant, represents a substantial investment in Mayo’s energy infrastructure. It will breathe new life into the long-dormant Asahi site, once a cornerstone of local industry, creating high-quality green jobs and providing the critical infrastructure needed to support Ireland’s climate and energy goals.

“Mayo commands a leading share of Ireland’s west coast, which has the potential to power the next generation of green hydrogen production and meet the needs of large energy users,” Minister Dillon said. “This is about more than clean energy. It’s about innovation, economic resilience, and long-term sustainability.”

The Minister also pointed to growing momentum across Mayo in renewable energy development, noting recent activity in battery storage, solar PV, biomethane, anaerobic digestion, and onshore wind as evidence of a clean energy ecosystem taking root in the region.

He emphasised the strategic importance of the west of Ireland in future energy planning, welcoming progress on the National Offshore Renewable Energy Designated Marine Area Plan (ORE DMAP), which will designate offshore sites for wind energy across Ireland's maritime area, including off the Mayo coast.

“The ORE DMAP is essential to our Programme for Government commitment to fast-track offshore wind. It will further solidify Mayo’s role in delivering Ireland’s offshore wind and green hydrogen ambitions,” Dillon said.

The development in Killala, backed by Constant Energy, forms a key part of that vision. Minister Dillon was clear that local communities must directly benefit from such initiatives.

“Projects like this must deliver real, tangible benefits — whether through job creation, local infrastructure, or community energy schemes. These developments aren’t just about energy; they’re about revitalising our towns, empowering our communities, and ensuring a sustainable future for generations to come.”

With planning now approved, the Hydrogen and Energy Centre is set to become a flagship example of Ireland’s green energy ambitions in action and Mayo is leading the charge.
