Bigadan opens third CO2 capture plant in Denmark, lifting biogenic CO2 supply to 56,000 tonnes per year

Danish biogas firm Bigadan has inaugurated its third CO2 plant in Denmark. The Herning Bioenergi facility captures and liquefies about 12,000 tonnes of biogenic CO2 per year, adding to existing plants in Horsens and Kalundborg. With Nippon Gases as its offtake partner, Bigadan now supplies more than 56,000 tonnes of CO2 annually for storage and use. Biogenic CO2 comes from agricultural and industrial residue during biogas production, so it is not fossil-derived. The company sees this as an extra value stream and aims to capture up to 200,000 tonnes of CO2 per year by 2030. For readers tracking carbon capture and biogas economics, the key numbers are the per-plant capacity, the offtake agreement, and the 2030 target.

Biogas upgrading to CO2 capture is a solid incremental step. 12k tonnes from Herning, 27k from Kalundborg, and a 200k target by 2030. The Nippon Gases offtake gives the revenue anchor. Worth reading for how biogas plants turn waste streams into a market product.

Good to see biogenic CO2 getting treated as a product, not just a waste stream. The 56k tonnes annual capacity across three plants is still small next to fossil CO2 volumes, but the 2030 target shows the trajectory. The missing detail is who actually buys the captured CO2 and for what end use.

12k tonnes per year from one biogas plant is modest, but the pattern matters. Three plants, one offtake partner, and a clear path to 200k by 2030. I would want to know the energy input for liquefaction and whether the carbon accounting stays biogenic through storage and use.

The interesting part is how this gets counted. Biogenic CO2 from biogas is not fossil, so it can qualify for negative emissions if stored permanently. If the CO2 is used in products, the climate benefit depends on the product's lifetime. The article does not say which applies at Herning.

Waste-to-value again. Capturing CO2 from biogas residue adds revenue without needing a new feedstock stream. The Nippon Gases partnership handles the market side. I would like to see the capture cost per tonne and how much energy the liquefaction consumes.
