Norwegian carbon removal developer Inherit Carbon Solutions has started operations at its second project, its first in Denmark. Its first load of liquefied biogenic CO2 has left Tønder Biogas in southern Jutland for permanent storage under the Danish North Sea.

In addition to the Greensand storage site opening covered above, this is the start of an individual removal supply chain feeding that site, with verified removal certificates issued for every tonne.

The first load was collected at Tønder on 23 September, three working days after Greensand’s formal opening. It was trucked to Esbjerg for entry into the Greensand storage chain, operated by INEOS Energy. Inherit plans to take about 10,000 tonnes of biogenic CO2 a year from the Tønder site. Haulage partner Litra carries out the road transport.

Tønder Biogas is owned by Copenhagen Infrastructure Partners. The plant turns organic waste into biogas, which releases CO2 as a by-product. Part of that CO2 already goes to a partner that produces e-methanol. Inherit now captures and liquefies a further share for permanent storage. Because the carbon comes from organic material, injecting it underground counts as a net removal from the atmosphere, not just an avoided emission.

Every tonne is verified by a third party and issued as a CO2 Removal Certificate (CORC) through the Puro.earth registry. Chain of custody is recorded from the biogas plant to the storage reservoir. Inherit says it has sold credits to buyers including Microsoft, DNV and Nordea.

The start-up makes Inherit, by its own account, the first company to deliver removals into both of Europe’s operating offshore CO2 storage sites. Its first project has been delivering CO2 to Northern Lights in Norway since February 2026. Inherit’s chief executive said the company and its biogas partners are already capturing and delivering CO2 to Europe’s first operating storage sites.

The project shows a smaller-scale model for bioenergy with carbon capture and storage (BECCS). Large BECCS projects at power stations take years of construction and often need state support. Biogas plants, by contrast, already produce a concentrated stream of CO2 that is relatively cheap to capture and liquefy. With access to storage sites by truck and ship, small and medium-sized biogas plants can become removal suppliers without building pipelines.

At 10,000 tonnes a year, Tønder is a small share of Greensand’s first-phase capacity of up to 400,000 tonnes a year. INEOS has said Danish biomethane plants will be the main source of CO2 in Greensand’s first phase, so similar arrangements are likely to follow.

Inherit was founded in 2021 and is based in Oslo. It is developing further BECCS projects at biogas and wastewater treatment sites in Denmark and Norway. It has previously raised NOK 40m and signed a multi-year removal agreement with Nordea.
