Global methanol production is generally produced from natural gas or coal. Green methanol (or bio-methanol) can be produced via biological, thermo-chemical, or electrofuel pathways.


Danish projects are examining the production of green methanol based on biogas. The applied technology involves splitting biogas into CO₂ and hydrogen (H₂) using an electrically-driven catalytic reactor, with additional energy injection of hydrogen from electrolysis to convert the products into methanol.

The electrical reactor offers a ground-breaking approach to energy supply and evolutionists’ traditional methods by directly harnessing electrical power. Topsoe’s  eREACT™ technology enables capturing more than 99% of the CO₂ from the syngas generation process.


A pilot facility has been started with the capacity to produce synthesis gas of about 2000 kg per day. The experience and the technology developed can be translated into an industrial system to make the technology cost-effective at a scale suited to a large biogas plant. The results of the pilot plant operation will be forming the basis for the design and commercialisation for industrial-scale electrified reactors.
