Biomethane expansion in Ireland: HoSt Energy Systems realizes a new biogas facility

11 November 2025
HoSt Energy Systems is currently developing a biogas plant located in Ireland. This facility will be one of the few new biogas plants in Ireland and is set to play a crucial role in realizing the nation’s vast, untapped potential for biomethane production. The plant will utilize anaerobic digestion technology for biogas production from organic residual streams and membrane biogas upgrading for up to 715 Nm³/h of biomethane, including a compression station to produce bioCNG. Completion of the project is planned for December 2025.

Turnkey biogas plant configuration

The project scope features two primary digesters and one after digester. All digesters are 25 meters in diameter and 7 meters in height. Two moving floors with a capacity of 120 m3, including a blending unit, will take care of the infeed. The complete technology package will be delivered by HoSt, including mixers, roofs, sensors, control system, local pipe and cable works, heat exchangers and sanitation. This last feature will exterminate all germs and pathogens in the feedstock.

For maximum biogas utilization, the project will include membrane biogas upgrading technology, delivered by Bright Renewables. The biogas upgrading system will yield 715 Nm³ of high-quality biomethane per hour from the biogas produced from up to 60.000 tonnes per day of waste such as dairy sludge, and food waste. The production capacity will be close to 6,000,000 Nm³ of biomethane yearly.

“With our turnkey biogas plant configuration, we are enabling efficient and reliable biomethane production that supports the customer’s decarbonization mission to convert organic waste from every sector into valuable use and to support Ireland’s energy transition." ”
Sjaak Klein Gunnewiek, Head of Sales Biogas Projects at HoSt Energy Systems.

Biogas expansion in Ireland

Ireland is at a crucial turning point in its energy transition and is about to unlock the significant potential of its domestic biogas sector. Although the sector’s development has been limited in the past, the country is now showing a strong commitment to reducing greenhouse gas emissions and achieving ambitious national climate and energy targets. As a result, there are more prospects for biogas in Ireland today. Biogas facilities enable Ireland to sustainably generate renewable energy, leveraging abundant agricultural resources and organic waste streams, while notably cutting methane emissions from agriculture and food production. By converting locally sourced organic materials into biomethane, Ireland reduces dependency on imported fossil fuels, supports rural economic development, and fosters a robust circular economy.

With almost 35 years of experience and over 450 projects worldwide, HoSt is uniquely equipped to handle complex waste streams efficiently, ensuring maximum energy recovery with the lowest environmental impact.
