'Green' investment to revitalise legacy Mayo industrial site
Planning permission has been granted for a new multi million-euro state-of-the-art Hydrogen Plant and Energy Centre at the former Asahi site in Killala.
Minister of State at the Department of the Environment, Climate and Energy Alan Dillon has welcomed the approval of planning permission for the project, calling it a major step toward Mayo’s ambition to lead Ireland in clean energy and become a national hub for green industry.
“This is a significant moment for Killala and north Mayo,” said Minister Dillon.
“Transforming the former Asahi site into a 106MW Energy Centre and cutting-edge Hydrogen plant is not just a substantial investment in renewable infrastructure, it’s a clear move toward establishing Mayo as a Green Energy Industrial Hub.”
The project will revitalise this legacy industrial site, create high-quality green jobs, and deliver critical infrastructure to Mayo.
Minister Dillon highlighted Mayo’s strategic position on Ireland’s west coast as a key advantage in the national energy transition.
“Mayo commands a leading share of Ireland’s west coast, which has the potential to power the next generation of green hydrogen production and supply of large energy users.
"This is about more than clean energy, it’s about innovation, economic resilience, and long-term sustainability.”
He also pointed to the growing momentum behind renewable energy in the region.
“In recent months, we’ve seen a surge in activity, from battery storage and solar PV to biomethane, anaerobic digestion, and onshore wind. These projects are laying the foundation for a clean energy economy rooted in Mayo.”
The minister welcomed the progress of the National Offshore Renewable Energy Designated Marine Area Plan (ORE DMAP), which will designate sites around Ireland’s entire sea area, including the west coast:
“The ORE DMAP is a vital part of our Programme for Government commitment to fast-track offshore wind development.
"It will further strengthen Mayo’s role in delivering Ireland’s offshore wind and green hydrogen ambitions.”
Crucially, Minister Dillon stressed that the benefits of these developments must be felt locally.
“Projects like Constant Energy’s investment in Killala must deliver real, tangible benefits for local communities, whether through employment, infrastructure, or community energy schemes.
"These initiatives are not just about energy; they’re about supporting our communities, revitalising our towns, and securing a sustainable future for generations to come.”
