Sisyphus

Sisyphus produces renewable carbon monoxide, a key feedstock for sustainable fuels and chemicals. Our catalytic process converts waste CO₂ at a fraction of the energy cost of conventional approaches, delivering renewable CO that integrates directly into existing chemical process infrastructure or is combined with hydrogen to synthesis gas for applications such as e-SAF production. With carbon efficiencies above 90% and flexible operation tied to renewable electricity availability, Sisyphus enables fossil-independent value chains without rebuilding them from scratch.
