to make Next Generation Fuels
Sustainable industries
Low carbon H2 & Syngas
to decarbonize refineries, NH3 or steel
CO2 capture
point of source capture for gas power plants or cement
Roughly 20% of global emissions cannot be tackled via electrification. The Energy Transition & Sovereignty calls for more than clean electrons: it calls for Clean Molecules.
