Virtuous recovery & use of biogas for on-farm anaerobic digestion

SUBLIME Energie, the first mission-driven company (société à mission*), enables the creation of local supply chains for bioLNG and bioCO2 and provides access to biomass for anaerobic digestion on farms located far from gas networks.

As part of a circular economy, our technology makes possible a new service for collecting, transporting, purifying and conditioning biogas from anaerobic digestion, responding to environmental and climate challenges, while increasing the resilience of the agricultural world and the energy sovereignty of territories.

Biogas liquefaction to meet the challenges of the methanisation market

Today more than 90% of biomass is held by farmers, but the development of the methanisation sector is hindered by the incompatibility between where biogas can be produced and where it is consumed. Historically, cogeneration has limited profitability due to the low efficiency of the engines involved, while the injection of biomethane into gas networks requires a costly purification stage. This excludes farms that are small in size or far from the gas networks.

At SUBLIME Energie, we propose a one-of-a-kind solution, adapted to low flow rates, enabling on-farm methanisation by pooling purification costs, thus making these small farms profitable on top of having a positive impact.

Lower investment and fair pay for farmers

Biogas liquefaction enables transportation between production and consumption sites

Pooled production in order to maximize the value of co-products (bioLNG and bioCO2)

Our innovation takes advantage of biogas produced from methanisation in the form of bioLNG, enabling the decarbonization of the trucking and agricultural machinery industries.

BioLNG offers a number of advantages for decarbonizing France's leading greenhouse gas emitting sector. Firstly, over the course of its entire life cycle, bioLNG reduces emissions by 85% as compared with fossil fuels. Secondly, bioLNG is adapted to the constraints of heavy and agricultural machinery, allowing for a range of over 1,000 kilometers, as well as rapid refueling and improved driving comfort. Lastly, bioLNG is a mature technology, with annual growth of +36% since 2016, and easily exploitable because as a low-carbon fuel, it can be used with a combustion engine.
