Cryo Pur

What Cryo Pur does

Cryo Pur is a French engineering company founded in 2015 that designs, manufactures, and operates cryogenic equipment for the simultaneous upgrading of biogas to biomethane (bio-LNG) and capture of food-grade liquid bio-CO2. The company's flagship process integrates pretreatment (H2S removal, dehumidification), CO2 separation through frosting/defrosting cycles on heat exchangers at -120°C, and biomethane liquefaction at -160°C into a single train, achieving 100% CH4 recovery and 99%+ biomethane purity while recovering process heat sufficient to cover digester heating needs. The portfolio is anchored by the Cryo LNG product line (scaling from 300 to several tens of thousands Nm3/h, producing 2-50 t/day of LNG) and has been extended into Cryo Flare for associated gas recovery, CCX for industrial high-CO2 vent streams, Direct Air CO2 Capture (DACC) for atmospheric carbon removal, and industrial flue gas CO2 capture.

The technology is protected by 8 worldwide patents stemming from 15 years of R&D led by founder Denis Clodic at Mines ParisTech, and underpins two industrial reference plants: the 300 Nm3/h farm-scale unit commissioned at Greenville Energy in Northern Ireland in January 2018, and the 700 Nm3/h industrial plant at Stord, Norway inaugurated in May 2022 in the presence of the Norwegian Prime Minister. Cryo Pur has also been a core partner in the BioGNVal wastewater-to-bio-LNG demonstration in Valenton, France, alongside SUEZ, SIAAP, GNVert (ENGIE), IVECO, and Thermo King.

The business model combines hardware sales (turnkey cryogenic units engineered and manufactured for each project) with recurring managed services (operation, maintenance, and performance guarantees over multi-year contracts), and a transaction component from sales of the liquid bio-CO2 byproduct at 99.9% purity. Go-to-market is direct enterprise field sales targeting agricultural cooperatives, biogas operators, wastewater treatment facilities, heavy-transport fuel off-takers, oil-and-gas operators with associated gas, and municipalities. The company is headquartered in Wissous, France, employs 11-50 people (with a stated core team of approximately ten engineers, researchers and technicians), and has operated as a 94%-owned subsidiary of Euronext-listed La Française de l'Énergie (FDE) since April 2022.

Core offering

Cryo Pur designs, manufactures, commercializes and operates cryogenic equipment that integrates biogas purification with biomethane and bio-CO2 liquefaction. The integrated process combines pretreatment (H2S removal, dehumidification), CO2 capture through frosting/defrosting cycles at -120°C, and biomethane liquefaction at -160°C, producing bio-LNG (99%+ purity) and liquid bio-CO2 (99.9% food-grade purity) for sale as renewable fuel and industrial gas.

Product overview

Cryo Pur offers a portfolio of cryogenic gas processing equipment centered on two core product lines: Cryo LNG for biogas upgrading and biomethane liquefaction, and Cryo Flare for flare gas recovery. These systems integrate three key steps—pretreatment (H2S removal, dehumidification), CO2 capture (separation and liquefaction), and biomethane liquefaction—into unified cryogenic processes. The company also offers modular add-on solutions including CCX for high-concentration CO2 vent streams, DACC for direct atmospheric capture, and industrial flue gas CO2 capture. All systems are supported by performance guarantees and full-service maintenance contracts. Cryo Pur's technology is protected by 8 worldwide patents developed over 15 years of R&D with Mines ParisTech.
