Greenville Energy Ltd, a renewable energy producer based in Northern Ireland, and French equipment supplier Cryo Pur have teamed up to develop a viable way in which to turn excess biogas into bio-LNG.

The launch of this project, which sees Northern Ireland’s first ever bio-LNG plant constructed, will introduce the world’s first small-scale commercial unit to produce liquefied biomethane from biogas – a key milestone for the global deployment of bio-LNG.

Under the agreement, Cryo Pur will deliver the design, assembly, installation and the commissioning of the bio-LNG plant, which is scheduled to be up and running in the first quarter of 2017.

Signing the first commercial contract is the validation of our strategy to cost-effectively build integrated bio-LNG production units

Its technology uses cryogenics in a single process to purify the biogas and separate out carbon dioxide (CO2), before liquefying the biogas and turning it into biomethane.

As a result, the Greenville project will be capable of producing three tonnes per day of bio-LNG or 10 GWh per year of storable and transportable renewable energy.

Jason Mitchell, CEO of Greenville Energy, explained, “As a pioneer in the British biogas industry, we’ve been actively looking for a way to efficiently produce and distribute more renewable energy. After a comprehensive analysis of available technical solutions, we opted for the production of liquefied biomethane.”

Denis Clodic, CEO of Cryo Pur, reinforced, “Signing the first commercial contract with Greenville Energy is the validation of our strategy to cost-effectively build integrated bio-LNG production units, with a great potential in the UK and Ireland markets.”


Greenville Energy, which began producing renewable energy via anaerobic digestion in 2012, utilises the waste from its family’s dairy farm in Tyrone, Northern Ireland, as well as waste from food manufacturers and retailers to produce biogas.
