Revcoo Freezes CO₂ Emissions with Cryogenic Tech

As European regulations drive stricter emissions limits, industrial manufacturers are under pressure to decarbonize. French cleantech startup Revcoo is stepping into this space with a cryogenic solution designed to capture CO₂ emissions without the chemical complexity of traditional methods. Their patented CarbonCloud technology works by freezing carbon dioxide out of factory exhaust streams, eliminating the need for solvents or water-based treatments. Once isolated, the CO₂ is processed into a liquid or gas form for storage or reuse.

Unlike conventional capture technologies that rely on energy-intensive and often toxic chemical processes, CarbonCloud runs entirely on electricity and doesn’t generate secondary waste. This positions the system as a lower-impact alternative for sectors grappling with what are known as "incompressible emissions"—carbon outputs that can’t be eliminated even with cleaner fuels. Industries like cement production, lime manufacturing, and glassworks fall into this category, as do biomass boilers and waste incinerators that emit biogenic CO₂.

The practical upside for manufacturers? Minimal disruption to existing infrastructure and a plug-in path to meet tightening carbon quotas without compromising operations.

From Regional Pilot to Global Scale-Up

Revcoo’s system is already in play at an operational lime facility in Hauts-de-France, where it currently captures two tonnes (metric) of CO₂ per day. This pilot installation has helped validate the technical approach while gathering field data to support scalability.

Following a $4.05 million seed round in 2022, the company is now pursuing $21.6 million in Series A funding to build a full-scale industrial demonstrator. The next unit is expected to operate at ten times the current capacity. With its sights set on both French and international markets, Revcoo plans to help manufacturers stay ahead of emissions penalties while enabling the reuse of captured CO₂ across various industries—from food production and construction materials to pharmaceuticals and synthetic fuels.
