Denmark-headed biomethane major BioCirc ApS has announced that it has signed an agreement with Microsoft for the delivery of 650,000 high-durability carbon removal units (CRUs) over seven years from BioCirc’s bioenergy with carbon capture and storage (BECCS) platform. The agreement supports Microsoft’s ambition to become carbon negative by 2030 and advances the supply of high-quality, durable carbon removal solutions within the circular bioeconomy.
Founded in 2021, BioCirc develops, integrates, and operates biogas-based energy solutions that utilize all value streams from biogas and related energy forms, such as biomethane – aka renewable natural gas (RNG), reduce emissions, and strengthen the energy system.
The company currently owns and operates eight industrial-scale biogas plants across Denmark, making it one of the largest biomethane producers globally, with an annual production capacity of more than 175 million m³ (~1.9 TWh).
Deliver carbon reduction units
Under the agreement, BioCirc’s most significant to date, BioCirc will deliver 100,000 CRUs per annum, with initial deliveries beginning in the second half of 2026 and continuing through 2032.
The CRUs will be generated from the capture and permanent storage of biogenic carbon dioxide (bioCO2) from five of BioCirc’s biogas plants in Denmark, beginning at Favrskov Biogas, and followed by Vesthimmerland Biogas, Haderslev Biogas, Grønhøj Biogas, and Vinkel Biogas.
Each CRU represents one metric tonne of bioCO2 that has been durably removed from the atmosphere and permanently stored in secure geologic formations beneath the Danish North Sea via Project Greensand.
All relevant lifecycle emissions – from biomass sourcing, facility operations, and downstream transportation – will be accounted for to ensure net carbon removal.
In addition, all biomass used in the project will meet stringent Danish eligibility requirements, and the facilities meet or exceed Denmark’s rigorous requirements for methane detection and release prevention through operational procedures and plant integrity.
The BioCirc project offers a durable and scalable approach to carbon removal while contributing to broader decarbonization of the energy system, said Phillip Goodman, Director of Carbon Removal Portfolio at Microsoft.
Leverage the BECCS platform
The agreement enables BioCirc to scale its integrated platform that combines biogas production, renewable energy, carbon capture and storage (CCS).
By leveraging multiple value streams from its biogas operations, BioCirc aims to expand cost-effective CO2 abatement while supporting decarbonization in hard-to-abate sectors such as agriculture and transport.
BioCirc’s approach combines high technical readiness with operational expertise and will serve as a repeatable model that can be scaled to many of the 1,500+ biomethane production sites in Europe.
The agreement is a major milestone for BioCirc and a meaningful validation of our approach to delivering durable carbon removal. We are thrilled to work with organizations such as Microsoft that are helping advance the market for durable carbon removal while addressing residual emissions and supporting global climate goals, said Bertel Maigaard, Group CEO at BioCirc.
