Canada-headed biogas technology provider Anaergia Inc. has announced that it has signed an agreement with Denmark-headed energy utility European Energy A/S to supply up to 60 000 tonnes per year of liquefied biogenic carbon dioxide for a period of 10 years sourced from Anaergia's Danish biogas plant, currently under construction in Tønder.

Biogenic carbon dioxide (CO2) is carbon dioxide that is released during the decomposition of organic matter such as food waste. All Anaergia plants use organic waste material to produce biogas, which is composed of methane and carbon dioxide.
The biogas is processed and upgraded to pipeline-quality biomethane – aka renewable natural gas (RNG) thus a clean stream of CO2 that normally gets released to the atmosphere where it originally came from.
The benefit for us is the ability to sell the biogenic CO2 from our plants, produced when we convert organic materials to methane and CO2. By selling this CO2 instead of returning it to the atmosphere, our plants contribute to decarbonizing hard-to-abate sectors, such as shipping, while becoming more profitable, as we turn this waste gas from our plants into a useful fuel, commented Dr Andrew Benedek, Chairman, and CEO of Anaergia.
Biogenic CO2 as feedstock
However, biogenic CO2 from organic material is considered a desirable raw material for low-carbon fuels as its use does not add new carbon to the atmosphere.
European Energy, a major multinational renewable wind and solar energy producer, will produce an electro-fuel (eFuel) from this biogenic CO2.
European Energy had previously entered into a green e-methanol supply agreement with A.P. Moller – Maersk (Maersk), a global leader in integrated container logistics services, with operations in 130 countries.
The green e-methanol will be used to power the first container vessel that A.P. Moller – Maersk is building to operate on this carbon-neutral fuel.
We are thrilled to team up with Anaergia for the supply of biogenic CO2 to our Danish e-methanol plants. In Anaergia, we have found a partner that like European Energy is committed to fighting climate change through new technologies that can make a real impact. We look forward to working with Anaergia, not only in Denmark but also throughout the world, said Knud Erik Andersen, Co-Founder, and CEO of European Energy.
Anaergia’s Tønder facility will provide the liquified CO2 from the anaerobic digesters and will build a state-of-the-art CO2 liquefaction system at the plant.
This is a great example of carbon capture and utilization (CCU), a critical step on the path toward net zero. We are looking forward to working with European Energy on this innovative endeavor, and to potentially working with them on other projects in the future as the need for green methanol rises globally, ended Dr Andrew Benedek.
