EnviTec Biogas has added three new contracts from first-time customers in Germany, expanding its order book with gas upgrading projects that will be built at the company’s Saerbeck facility in the coming months, reports Bioenergy Insight.
The first project, located in Biburg, Lower Bavaria, marks EnviTec’s entry into the Bavarian market after constructing 112 biogas plants across Germany. A company official said the customer currently runs a gas upgrading plant using water scrubbing technology, which will be retired once the new EnviThan upgrading system is installed.
Bioenergie Biburg’s Benedikt Bachmeier said the agreement took considerable time to finalise, noting that the two years between the initial meeting at the Biogas Convention & Trade Fair in Nuremberg in 2023 and the signing were shaped by policy uncertainty, shifting market conditions and long permitting timelines.
The 1,000 Nm³/h biomethane plant is expected to begin feeding into the grid in July 2026. A major advantage of the project, according to EnviTec, is the inclusion of the booster compressor needed to meet grid pressure, allowing faster injection. The limited space available at the existing biogas site also influenced the project award, with the company highlighting that its container-based design can adapt to on-site structural constraints.
EnviTec’s modular design is also central to the second new contract, awarded by Hamme Energie GmbH & Co. KG in Osterholz-Scharmbeck near Bremen. An EnviThan gas upgrading unit is being added to an existing biogas plant. The system is already in production in Saerbeck and will be delivered in March 2026. The 137 Nm³/h plant can be expanded to 232 Nm³/h of biomethane with the addition of membranes. The upgraded gas will feed into the Osterholzer Stadtwerke network, using dairy cattle slurry, cattle manure and silage maize from the operator’s own farm.
The third contract, signed in Reichardtswerben, Saxony-Anhalt, is with a Dutch operator managing a large dairy farming enterprise. The plant will initially produce 200 Nm³/h of biomethane, expandable to 400 Nm³/h, and will inject into the Ontras network to supply the fuel market. EnviTec confirmed that all components have already been ordered and production can begin as soon as the container arrives.
Production capacity at EnviTec’s Saerbeck facilities remains strong as demand for biomethane solutions continues to rise.
