A Spanish biomethane company is partnering with an e-methane producer to capture and reuse biogenic CO₂ that would otherwise be released during biogas upgrading.
AGR Biogás announced it will supply carbon dioxide from its biomethane plants to TURN2X, which will convert it into e-methane using green hydrogen. The collaboration turns a production byproduct into feedstock for renewable fuel.
Biomethane production naturally separates CO₂ from biogas during the upgrading process. AGR Biogás generates this biogenic carbon dioxide by processing organic waste streams. Rather than venting it, the company will now channel it to adjacent TURN2X facilities.
The partnership launches at two locations in Andalusia and Extremadura. TURN2X will build installations directly beside AGR Biogás plants to enable the carbon dioxide transfer.
The arrangement creates a circular carbon system. Organic waste becomes biogas, which yields both biomethane and biogenic CO₂. That CO₂ then combines with green hydrogen to produce additional renewable gas.
AGR Biogás will also receive renewable heat from TURN2X operations, replacing thermal energy the biomethane producer would otherwise need. This heat exchange further improves the environmental performance of both processes.
AGR Biogás CEO David Piñero emphasized maximizing value from biogenic CO₂. He said the collaboration positions biomethane plants as central hubs in Spain’s renewable gas ecosystem.
The companies will explore sharing gas grid infrastructure to reduce connection costs. TURN2X’s modular reactor design allows installation directly at CO₂ sources, eliminating transportation needs.
