Bio-LNG liquefaction test bench at Montoir-de-Bretagne: LIBIOPTIM
Elengy and ENGIE Lab CRIGEN have designed a new liquid biogas packaging process. This process provides competitive solutions for major clients in commercial terms and notably a 30% reduction in production costs. It offers a low-carbon more environmentally-friendly fuel by reducing CO2 emissions by 80% and particle emissions by 95%.
Bio-LNG is essentially biomethane, a renewable gas that mainly comes from the anaerobic digestion of agricultural and household waste. We liquefy it to reduce its volume 600 times, thereby making it easier to use and transport. An essential driver of the energy transition, it can replace polluting fossil fuels such as coal or oil.
The aim of the test bench is to test and describe the performance of the process designed by the liquefaction laboratory. This will then enable us to move to the liquefaction development and bio-LNG production stages.
The aim is to validate the solution on a small scale in order to provide a anaerobic digestion unit with a liquefaction unit on a large scale, about 5 times bigger, in order carry out biomethane liquefaction. The aim is to make bio-LNG available to road hauliers and clients, for example for mobility purposes to supply heavy vehicles currently running on LNG.
Bio-LNG will help us achieve carbon neutrality and help industrial companies who wish to decarbonise their businesses. This is therefore a key tool in the very short-term.
This project is perfectly in line with Elengy’s strategy to offer new gases to the market.
