A new startup has joined our TEAM incubator! This is Carbon Cage, founded by Jean-Michel Herri and Nicolas de Breyne.


This young company, stemming from 30 years of R&D, provides a breakthrough solution for industrial CO2 capture by halving operational costs compared to the reference process, and by opening up access to the new compensation market for atmospheric CO2. The project therefore consists of designing, operating, and validating an industrial CO2 capture prototype capable of operating on both industrial flue gases and direct CO2 capture from the atmosphere. This process offers hybridization potential with industrial water purification. The ultimate goal in 9 years is to offer scalable containerized technology.


Carbon Cage is an idea from Jean Michel Herri, a scientific expert on clathrate hydrates, researcher-lecturer and former director of the SPIN center at Mines Saint-Étienne, and Nicolas de Breyne, who has a background in international business (Master of Science in Engineering Business) and in managing industrial and commercial site groups.
“We chose the TEAM incubator for its unique scientific ecosystem and its proximity to Mines Saint-Étienne, a recognized innovation player, and for its expertise. By joining TEAM, we seek to benefit from the school’s skills and infrastructure, as well as its network of partners, to accelerate the development of our solutions. We see this support as a strategic opportunity to develop our technology and strengthen our market credibility.”

In the short term, the startup Carbon Cage is recruiting two engineers specialized in numerical modeling and technological development in order to offer a containerized technology to validate the pilot phase on site. The startup is therefore seeking talent and investors to support its growth up to the prototype in 2032, with a realistic pre-money valuation target of 20 million euros (comparable analysis of other startups positioned in the same market, with less efficient technology).
