The BioCO₂ project highlights the strength of ENGIE R&I’s collaborative model.
The BioCO₂ project is a concrete illustration of the Innovation Studio team’s ability to:
Thanks to this approach, a new local biogenic CO₂ value chain has been developed close to ENGIE Renewable Gases’ existing anaerobic digestion facilities.
The major partnership between ENGIE and Cerafel – Prince de Bretagne, announced at the Paris International Agricultural Show, is a clear illustration of this new biogenic CO₂ offer.
The objective is to create a regional bio‑CO₂ value chain based on agricultural anaerobic digestion.
Two ENGIE biogas plants will supply this value chain: Noyal‑Pontivy, already in operation, and Ploufragan (near Saint‑Brieuc), currently under construction.
The Pontivy facility will be equipped with an innovative technology capable of capturing, purifying (>99%), and liquefying renewable CO₂ directly for greenhouse growers, using CryoCollect’s technology. CryoCollect is a startup in which ENGIE New Ventures has invested.
Starting in 2026, several thousand tonnes of biogenic CO₂ will be supplied to the first 14 Prince de Bretagne tomato producers.
Bio‑CO₂ offers a sustainable alternative to fossil‑based CO₂, which is transported over longer distances and subject to high price volatility, delivering significant benefits for both farming operations and the environment:
The BioCO₂ project highlights the strength of ENGIE R&I’s collaborative model: an operational business entity within the Group, a startup backed by ENGIE New Ventures, and the R&I Innovation & Engagement team combined their expertise to accelerate the deployment of a tangible solution serving the energy transition.
By bringing together industrial capabilities, technological agility, and an innovation-driven vision, this partnership has helped structure a new biogenic value chain, open up a promising market for ENGIE, and deliver a circular, sustainable response to local territorial needs.
