Bio-LNG and Bio-LCO2 from biogas

Upgrade to the future now!

“Green Line Liquid” technologies make it possible to produce alternative and sustainable fuels biomethane and Bio-LNG (“Liquefied Natural Gas”) from biogas. RUHE Biogas helps to ensure the economic operation of biogas plants in accordance with the EEG and contributes to save CO2 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 regulated due to the 37./38. BImSchV.

Our services

We transform your biogas plant into a biofuel production facility – turnkey from planning to marketing. With our network, we help you with greenhouse gas accounting under REDII and deliver a turnkey 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 carbon footprint, without the need to add expensive cooling liquids such as nitrogen or mixed refrigerants. RUHE Biogas offers a careful-free approach to all operators and serves the entire supply chain – from feasibility study and design to management of the plant, storage and a long-term off-take concept (as with the EEG).
