France produces more biomethane than almost any other European country, yet a significant share of its agricultural biogas potential goes untapped. The reason: most farms sit too far from the gas grid to make connection viable, and the infrastructure cost runs to 100,000 euros per kilometre.
Jules Vasse, head of public affairs at SUBLIME Énergie, joins Climate Solutions News Publisher Dominic Shales to explain the company's answer to that problem. SUBLIME liquefies raw biogas directly on the farm using a patented carrier agent, collects it by truck every few days, and separates it into bio-LNG and liquid bioCO2 at a centralised hub shared across multiple farms. The model bypasses the gas grid entirely.
In April 2026, SUBLIME inaugurated Charlie, the world's first on-farm biogas liquefaction system, at a pig farm in Brittany. Jules talks through what the demonstrator means for the company's development, what comes next with the Delta commercial project, and how France's new IRICC carbon intensity regulation could transform the economics of bio-LNG for heavy transport.
With the Strait of Hormuz crisis disrupting European LNG supply, the conversation around domestic renewable gas has become more urgent. This episode explores why farm waste may be one of the more practical answers.
