Danish biogas producer Bigadan, backed by Arjun Infrastructure Partners, has completed Europe's first fully operational biogenic carbon capture and storage chain. CO2 captured at its Kalundborg Bioenergy plant was injected into the North Sea's Greensand facility, operated by INEOS Energy, marking a shift from pilot to industrial-scale operation. The company converts agricultural, household, and industrial organic waste into renewable gas and biofertiliser while permanently storing the biogenic CO2 under a contract with the Danish Energy Agency. Greensand's first commercial phase can store up to 400,000 tonnes of CO2 annually, with potential to scale to 4-8 million tonnes per year as the market develops. This project demonstrates how integrated circular energy platforms can combine waste treatment, biomethane production, and carbon removal. For carbon market participants, it offers a concrete example of a fully paid, operational biogenic carbon removal value chain in Europe.

Finally a real biogenic CCS chain. Greensand's 400k t/yr is modest but the path to 4-8 million is what makes it worth tracking. The contract with the Danish Energy Agency gives it a solid revenue base.

Is there any detail on the capture technology and its energy penalty? Biogas upgrading already uses energy, and adding CCS on top could eat into the net carbon removal if the electricity isn't clean. Would like to see a lifecycle analysis.

The Danish Energy Agency contract is the key enabler. Without a guaranteed buyer for the carbon removal, this wouldn't happen. Other countries should look at this as a template for how to finance biogenic CCS without relying on voluntary markets alone.

What's the cost per tonne here? Biogas is already expensive compared to fracked gas, and adding CCS probably pushes it further. The question is whether the waste treatment revenue offsets enough. I'd want to see the actual numbers before calling it a model.
