SUBLIME Energie, the first mission-driven company
SUBLIME Energie is a mission-driven company (société à mission*), a Deeptech start-up, and a spin-off from Mines Paris PSL. Since its creation in 2019, the company has worked on its one-of-a-kind technology for biogas liquefaction enabling the development of small-scale on-farm anaerobic digestion and the local production of bioLNG, a low-carbon fuel for heavy machinery, and bioCO2.
*A qualification attributed to businesses for continued compliance to social and/or environmental commitments.
Our raison d’être :
Contribute to the necessary ecological, social and energy revolution by developing the production and valorization of low-carbon renewable gases to replace their fossil equivalents.
Our 3 Objectives
Objective 1 :
Develop the production, recovery and use of all biogas components in order to replace fossil fuels with low-carbon renewable gases.
Objective 2 :
Develop the circular economy and promote the activity and independence of agricultural regions, farmers, and other local stakeholders
Objective 3 :
Develop research in the fields of renewable gases, circular economy and responsible business management, to industrialise its results and make them known, particularly through teaching.
