From steel to structure: HoSt’s biogas plant in Ireland takes shape

1 March 2026
Construction is moving fast at our biogas project site in Ireland, where what began as steel framework and concrete foundations is now visibly becoming a full-scale biomethane facility. The digester tanks have risen from the ground, and for the first time, the sheer scale of this new plant is becoming clear to see. Our team has been on-site completing the outer shell of the digester tanks. As this stage nears the finish line, focus now shifts indoors, where the core internal components will be installed before the roofs are sealed into place. It's a stage of construction that captures both how far the project has come and how much work still lies ahead.

A Milestone for Ireland's Biomethane Expansion

This facility marks another step forward in Ireland’s growing biomethane sector. HoSt is delivering one of the country’s newest biogas plants, engineered to process up to 60,000 tonnes of organic waste each year including dairy sludge and food waste, and convert it into clean, renewable energy.

Powered by advanced membrane upgrading technology, the plant will generate close to 6,000,000 Nm³ of high-quality biomethane annually, transforming local waste streams into a sustainable fuel source that feeds directly into Ireland’s renewable energy targets.

Key Components of the Facility

The project’s core infrastructure includes:

  • Two primary digesters and one after-digester
  • Two 120 m³ moving floors, including a blending unit
  • Membrane-based biogas upgrading technology

Together, these systems create a scalable, high-efficiency solution for turning organic waste into renewable biomethane.

Looking Ahead

Ireland still holds considerable untapped potential in the biogas sector, and the country is well-positioned for continued growth in renewable energy. Unlocking that potential further will require supportive policy frameworks and expanded gas grid infrastructure to allow more biomethane producers to inject directly into the national network.

HoSt is proud to be part of Ireland’s renewable energy journey through this project, and we look forward to sharing further updates as construction continues.
