SUBLIME Energie provides a service that collects, transports, purifies and liquefies on‑farm biogas into bioLNG and bioCO₂, enabling small and remote farms to profit from anaerobic digestion despite low flow rates and distance from gas networks. By pooling purification costs across multiple farms, the company creates local supply chains for renewable gases, delivering low‑carbon bioLNG for heavy‑duty and agricultural machinery and generating revenue from captured bioCO₂.

Problem
Biomass from farms is abundant, yet most small or remote farms cannot profitably produce biogas because traditional cogeneration is inefficient and injecting biomethane into gas grids requires expensive purification infrastructure. This geographic and economic mismatch limits the growth of anaerobic digestion and the broader circular‑economy transition.
Solution
Sublime Energie offers a mission‑driven service that collects, transports, purifies and liquefies biogas on‑farm into bioLNG and bioCO2. By pooling purification costs across multiple farms, the company makes low‑flow anaerobic digestion economically viable even for sites far from gas networks. The resulting bioLNG can be shipped to consumption points, enabling renewable fuel use in heavy‑duty and agricultural machinery while providing a market for bioCO2. This creates local supply chains for renewable gases, enhances energy sovereignty of territories, and supports decarbonization of transport and farming sectors.
Target Audience
Primary customers are small to medium‑size farms located away from natural gas pipelines and logistics operators or fuel distributors seeking renewable bioLNG for heavy‑duty and agricultural fleets.
Features
- On‑farm anaerobic digestion integration with a low‑flow biogas liquefaction unit tailored for small‑scale producers
