BioCirc lands 7-year Microsoft carbon removal deal

By AI, Created 9:10 AM UTC, May 20, 2026, /AGP/ – BioCirc has signed a 7-year agreement to supply Microsoft with 650,000 high-durability carbon removal units from Danish biogas plants starting in 2026. The deal is BioCirc’s largest to date and ties together biogas, carbon capture and offshore storage in a project aimed at scaling durable removals.

Why it matters: - The agreement gives BioCirc a major commercial anchor for its bioenergy carbon capture and storage platform. - Microsoft is adding another large carbon removal supply line as it works toward becoming carbon negative by 2030. - The project could help make durable carbon removal more bankable for other buyers and developers.

What happened: - BioCirc signed a 7-year agreement with Microsoft for 650,000 high-durability carbon removal units, or CRUs. - Deliveries are set at 100,000 CRUs per year, with initial deliveries beginning in the second half of 2026 and continuing through 2032. - The deal is BioCirc’s largest to date. - The CRUs will come from BioCirc’s BECCS platform across five biogas plants in Denmark, starting at Favrskov Biogas.

The details: - Each CRU equals one metric ton of carbon dioxide durably removed from the atmosphere and permanently stored. - Captured biogenic CO₂ will be stored in secure geologic formations beneath the Danish North Sea through Project Greensand. - The storage site is the Greensand Future site in the Danish North Sea, with injection approximately 1,500-1,800 metres beneath the seabed. - The project will also use Vesthimmerland Biogas, Haderslev Biogas, Grønhøj Biogas and Vinkel Biogas. - All lifecycle emissions from biomass sourcing, facility operations and downstream transportation will be accounted for to support net carbon removal. - The biomass must meet Danish eligibility requirements. - The facilities meet or exceed Denmark’s requirements for methane detection and release prevention through operational procedures and plant integrity. - The project creates a full CCS value chain from decentralized capture to offshore storage. - The Danish Energy Agency supports the project through the NECCS fund. - The NECCS subsidy and Microsoft’s carbon removal purchase are both necessary for the project to be financially viable. - BioCirc says the platform combines biogas production, renewable energy and CO₂ capture and storage. - BioCirc aims to use multiple revenue streams from biogas operations to expand cost-effective CO₂ abatement in hard-to-abate sectors such as agriculture and transport. - BioCirc says the approach is designed as a repeatable model that could scale across many of Europe’s more than 1,500 biomethane production sites.

Between the lines: - The deal suggests Microsoft is willing to back projects that combine near-term removals with strict carbon accounting and permanent storage. - For BioCirc, the agreement helps validate a model that depends on both public support and private demand to get to scale. - The structure also shows how carbon removal markets are still leaning on a mix of subsidies, offtake contracts and operational certainty to move projects forward.

What’s next: - BioCirc will begin partial deliveries in 2026 as the project ramps up. - The company will continue deliveries through 2032 if the project stays on schedule. - BioCirc may use the Microsoft deal as a reference point for additional buyers and future project development. - Microsoft will add the removals to its broader carbon removal portfolio as it pursues its 2030 climate target.

The bottom line: - The Microsoft deal gives BioCirc a large-scale customer and puts a long-duration, Denmark-based carbon removal project on the map.
