Concept and Technology

Step 1: Green methanol synthesis

Renewable energy, captured CO₂ and green hydrogen are combined to produce green methanol value chain . This is the feedstock for the entire value chain. The methanol synthesis step is well-aligned with commercially proven technology (TRL 8–9 at industrial scale).

Methanol is decomposed into syngas, a mixture of carbon monoxide and hydrogen, using renewable heat. This endothermic reaction simultaneously stores renewable energy as thermochemical heat. The stored syngas can be held until needed, decoupling fuel production from wind and solar intermittency.

Step 3a: Syngas-to-methane (TCES discharge)

Through methanation, syngas is converted to synthetic natural gas, releasing high-temperature heat. The produced methane can be used in existing natural gas infrastructure or injected into the gas grid.

Alternatively, syngas is converted to dimethyl ether (DME), a clean-burning renewable diesel alternative suitable for transport. The two-step route via syngas provides operational flexibility compared to direct methanol-to-DME synthesis.
