Cleantech/Energy - Transport of liquified biogas to boost biomethane production

Spin-off of a French laboratory of excellence, PSL - MINES de Paris, and société à mission, the deeptech start-up develops a unique technology to liquify non-upgraded biogas in order to efficiently connect small production sites to biomethane consumption sites. It drastically increases the access to a huge untapped potential of biogas, produced via on farm anaerobic digestion of organic matter, reduces the cost of biogas valorisation by 50% with mutualized processing  and allows the production of bioNGV, a low-carbon fuel for heavy mobility and bioCO2 to replace fossil CO2 .Biogas liquefaction POC in T1 2020 ; Lab demonstrator under construction, tests in T1 2022 ; first commercial project in 2023 in Brittany with 11 farmers and 2-3 transportation companies. 2 patents; 3 contracts for 2020 | TRL: 5 | TAM: 15 B€ | Next Step: industrial demonstrator | Amount sought: 5 M€
