Bio-LNG and Bio-LCO₂ from biogas

Upgrade to the future now!

“Green Line Liquid” technologies make it possible to produce the alternative and sustainable fuel Bio-LNG (“Liquefied Natural Gas”) from biogas. RUHE Biogas thus helps to ensure the economic operation of biogas plants and contributes to CO₂ savings in the transport sector.


In order to achieve the targets set out in the Paris Climate Agreement of 2015, RED I was amended to RED II, which stipulates, among other things, that emissions are to be reduced by 40% by 2030 compared to 1990 levels. The German government has gone one step further and set itself the goal of reducing greenhouse gas emissions by 55% compared to 1990 as part of the Federal Climate Protection Act. In Germany, this is essentially due to the 37./38. BImSchV regulated.

Our services

We transform your biogas plant into a biofuel production facility –  from planning to marketing. With our network, we help you with greenhouse gas balancing under REDII and provide an off-take concept for the produced bio-LNG. You do not want to invest? No problem. We take the raw biogas of you with a long-term agreement and place the “Green Line Liquid” plant to your farm.

The Micro-liquefaction technology for bio-LNG produces liquid, clean fuel with zero emissions and a neutral CO₂ balance, without the need to add expensive cooling liquids such as nitrogen or mixed refrigerants. RUHE Biogas offers a worry-free approach to all operators, servicing the entire supply chain – from feasibility study and design to plant management, storage, and a long-term off-take plan.
