SUBLIME Energie proposes a decentralized model to exploit biomethane outside conventional gas grids, addressing a critical barrier to the valorization of renewable resources.
In France, an unconnected potential of around 26 TWh is estimated for 2050; much of it remains inactive due to the technical and economic impossibility of integrating into transport and distribution infrastructure.
SUBLIME’s approach aims to capture a significant fraction of that resource through local units for processing and distributing renewable gases.
From waste to bio-LNG
The proposed value chain focuses on acquiring raw biogas produced on farms, with direct purchase by the operator.
This strategy eliminates the need for farmers to make upfront investments in biogas upgrading and conditioning stages, transferring to the company the technical and financial responsibility for converting it into a gas compatible with local uses.
From an economic standpoint, SUBLIME Energie’s model introduces a disruptive shift:
The estimated biomethane potential in France reaches 26 TWh by 2050, but much of it remains untapped due to infrastructure limitations—precisely the problem this model solves.
Energy benchmark: biogas vs bio-LNG vs natural gas
In a context where decarbonizing heavy transport remains a challenge, bio-LNG is emerging as a key bridging solution, especially in sectors that are difficult to electrify.
From the perspective of rural development and sector sustainability, representatives of the livestock sector emphasize the interdependence between the future viability of livestock farming and the democratization of biogas production.
The adoption of models that reduce barriers to entry and provide technical and financial support is considered necessary for farms to adapt to regulatory and market frameworks based on decarbonization.
Strategic conclusion: truly decentralized energy
The “Charlie” project is not only a technological innovation, but an energy paradigm shift: moving from a centralized system to a distributed, modular, and resilient one.
Drawing inspiration from traditional logistics models, such as milk collection, SUBLIME introduces a simple but highly scalable industrial logic.
Ultimately, this model positions biogas not only as an environmental solution, but as a strategic energy asset within Europe’s energy transition.
