Our mission

Closing the carbon loop with chemistry

We utilize captured CO₂ from industrial sources and convert it into drop-in sustainable electo-fuels (e-fuels) using renewable electricity — creating a closed carbon cycle that decarbonizes aviation and heavy transport without changing existing infrastructure.

Founded in Laval and developed in collaboration with Polytechnique Montréal, our Process Intensified Power-to-Liquid process addresses one of the hardest-to-abate sectors in the global economy.

See the process

CO₂ capture

Carbon dioxide is captured from industrial point sources — factories, biofuel producers, cement plants — before it reaches the atmosphere.

Green hydrogen

Water/steam is split via electrolysis powered by renewable electricity, producing green hydrogen with low carbon footprint.

Catalytic membrane reactor

CO₂ and H₂ are converted via our proprietary direct CO₂ hydrogenation process into liquid hydrocarbons.

Drop-in fuel output

Finished SAF and e-fuels are certified drop-in replacements — no aircraft or engine modifications required.

Applications

Decarbonizing
hard-to-abate sectors

Sustainable aviation fuel (SAF)

SAF reduces lifecycle carbon emissions by up to 80% compared to conventional jet fuel. Drop-in ready for all commercial aircraft — no infrastructure changes required.

Aviation

Heavy transport & marine

E-diesel and e-methanol for long-haul trucking, shipping, and port operations — sectors where electrification alone cannot deliver the required energy density.

Transport

Industrial decarbonization

Carbon-neutral process fuels for industrial applications — leveraging existing industrial CO₂ point sources as feedstock to close the carbon loop on-site.
