Microsoft & BioCirc’s 590,000 tonne Carbon Capture & Storage

BioCirc is a circular bioeconomic company, aiming to establish and produce green energy across all forms.

The company aims to integrate solar and wind energy, biogas, electrolysis, pyrolysis and Power-to-X technologies into a circular system.

BioCirc has signed a seven-year agreement with Microsoft to permanently remove and store 590,000 tonnes of CO₂ through carbon capture and storage technology. 

The partnership marks a significant step forward for large-scale carbon removal within Europe’s circular bioeconomy and supports Microsoft’s goal of becoming carbon negative by 2030. 

Carbon capture and storage

Under the agreement, BioCirc aims to deliver 590,000 Carbon Removal Units through its BECCS platform across five Danish biogas plants. 

By combining biogas production, renewable energy and carbon capture, the project demonstrates how industrial collaboration can accelerate climate solutions for hard-to-decarbonise sectors.

The captured biogenic CO₂ is set to be transported and permanently stored beneath the Danish sector of the North Sea through Project Greensand. 

“The agreement is a major milestone for BioCirc and an important validation of our approach to delivering permanent CO₂ removal,” says Bertel Maigaard, Group CEO of BioCirc.

“We are excited to collaborate with a leading international company like Microsoft, which, while addressing residual emissions and supporting global climate goals, is also helping to develop the market for permanent carbon removal.”

This process creates a complete carbon capture and storage value chain, from decentralised capture at biogas facilities to offshore geological storage, helping establish long-term infrastructure for carbon removal in Denmark.

Scaling carbon removal

The project highlights the growing role of scalable carbon removal technologies in achieving global climate targets. 

BioCirc’s integrated model combines renewable energy production with cost-effective CO₂ removal, while maintaining strict environmental standards for biomass sourcing, methane detection and operational efficiency. 

By creating additional value streams from biogas operations, the company aims to support emissions reductions in sectors such as agriculture, shipping and heavy transport, where reducing carbon emissions remains especially challenging.

“BioCirc has entered into a seven-year agreement with Microsoft to deliver 100,000 tonnes of permanent CO₂ removals annually,” writes Thomas Tranekær, Group CFO & Deputy CEO at BioCirc, on LinkedIn.

“Partnering with a world-leading company like Microsoft is a major milestone for our CCS project and a strong validation of BioCirc’s approach to large-scale carbon abatement.”

The agreement reflects increasing confidence in permanent carbon removal as a necessary tool in the global transition toward net zero emissions. 

Microsoft’s commitment provides financial support, enabling BioCirc to expand its operations and strengthen the market for verified carbon removal solutions. 

With annual deliveries beginning in the second half of 2026 and continuing through 2032, the partnership represents an important example of how technology companies and renewable energy providers can work together to build scalable climate solutions for the future.

Microsoft’s carbon removal

Microsoft has committed to becoming carbon negative by 2030 by cutting its GHG emissions by more than half, removing its remaining emissions and ultimately eliminating the equivalent of its historical emissions by 2050. 

To achieve this, the company is investing in a broad portfolio of carbon removal solutions that emphasise transparency, scientific verification, durability and long-term environmental benefits. 

“BioCirc’s project offers a permanent and scalable approach to carbon removal while also contributing to a broader transformation of the energy system,” says Phillip Goodman, Director of Carbon Removal Portfolio at Microsoft.

“Scalable, high-quality carbon removal solutions with strong traceability, such as BioCirc’s, are essential for the development of a robust global carbon removal market.”

Microsoft is prioritising projects that demonstrate measurable net carbon removal, strong lifecycle analysis and responsible monitoring practices, while also helping accelerate the development of a scalable global carbon removal market.
