Stirling Cryogenics, a HYSYTECH group company, and AB are collaborating on the design, construction, installation and maintenance of liquid biomethane production plants with cryogenerators based on Stirling technology.

This technology is based on a consolidated process, already used worldwide in more than 3,000 cryogenic installations, employing a “proven-technology” consolidated over decades of operation in the most varied sectors, from superconductors to nuclear-physics research.

Under the agreement, AB will produce a product line called CH4LNG, the liquefier designed as a single unit, set up with cryogenerators built by Stirling Cryogenics for bioLNG systems up to 12 tonnes per day suitable for the liquefaction of biomethane for small and medium-sized biogas upgrading plants.

Combined with the BIOCH4NGE® upgrading solution (AB product line for Biogas Upgrading), CH4LNG allows the transformation of biogas into bioLNG carbon neutral, effectively contributing to the energy transition and decarbonisation effort, in line with European policies.

The agreement allows to combine the strengths of the two companies to seize the significant opportunities in the biomethane and bioLNG market.
