Low-carbon fuels from CO₂ and hydrogen or syngas
Producing low-carbon molecules to decarbonize hard-to-abate sectors. KHIMOD enables the conversion of captured CO₂ and low-carbon hydrogen – or syngas generally compounded of CO₂, CO and hydrogen – into low-carbon methane, low-carbon methanol or Sustainable Aviation Fuels (SAF), using high-performance continuous processes.
Explanation
What are low-carbon fuels ?
Low-carbon fuels are synthetic fuels produced by combining captured CO₂ with low-carbon hydrogen. Through processes such as CO₂ hydrogenation or syngas conversion, these molecules can replace fossil-based fuels in sectors where electrification is not sufficient.
They offer a scalable pathway to reduce emissions in hard-to-abate industries such as aviation, maritime transport and some industrial processes.
