BECCS - Unlocking negative emissions
Empowering BECCS (Bioenergy with Carbon Capture and Storage) with fully electric COâ‚‚ capture technology
Achieving negative emissions with BECCS
As the world moves toward net-zero and beyond, Bioenergy with Carbon Capture and Storage (BECCS) stands out as one of the few viable pathways to achieve negative emissions. Capsol Technologies’ fully electric, Hot Potassium Carbonate (HPC)-based CO₂ capture solutions are ideally suited for bioenergy facilities, delivering low-energy, zero-steam, and low-OPEX performance - at commercial scale.
Why Capsol’s Technology is ideal for BECCS?
✓ Fully electric operation - No steam dependency - ideal for bioenergy plants without waste heat
✓  Low operating life - HPC has been commercially proven for decades with low degradation and zero toxic byproducts
✓  Easy energy consumption - Enabled by advanced heat recuperation and mechanical vapor recompression (MVR)
âś“Â Â High purity COâ‚‚Â - Ready for permanent storage or utilization
✓  District heating potential - Reuse of captured heat enables local energy integration and additional revenue
Proven technology for scalable, reliable COâ‚‚ removal

Capsol’s platform uses a robust, well-understood solvent - HPC (Hot Potassium Carbonate) - to absorb CO₂ from compressed and conditioned flue gases. Our two commercial products are both applicable to BECCS deployments:
CapsolEoP® (End-of-Pipe)
Our full-scale carbon capture solution for integration at bioenergy and biomass plants:
âś“Â Compresses flue gas to 5-10 bar
âś“Â Transfers heat to reduce energy use
âś“Â Expands cleaned flue gas to recover compression energy
âś“Â Uses MVR units to provide all needed steam
âś“Â Delivers scalable, low-OPEX performance
CapsolGo®
Our container-based, mobile demonstration units designed to validate performance across industry sites:
âś“Â Testing real flue gas on-site
âś“Â Validating heat integration opportunities
âś“Â De-risking full-scale deployment
Accelerating carbon removal from bioenergy
BECCS projects face unique integration challenges - from flue gas moisture content to variable heat availability. Capsol’s experience, modular technology, and solvent stability ensure dependable performance across a wide range of feedstocks and plant configurations:
âś“Â Â Biomass-fired power generation
âś“Â Â Waste-to-energy plants
âś“Â Â Pulp and paper mills with energy recovery
Advantages of Capsol's HPC solution for BECCS
Additional district heating generation
For customers that are connected to a district heating network, the CapsolEoP® solution can boost their energy production during winter months. Here our technology makes a capture facility an additional revenue generator. Â
Engineering work for clients has produced energy consumption numbers of 0.5-1.5 GJ/tonnes of COâ‚‚Â captured, depending on the composition and temperature of the flue gas (not including liquefaction).Â
Low energy consumption and fully electric
A Capsol carbon capture plant can be solely powered by electricity, which results in an overall low energy consumption due to the highly efficient internal heat pump effect for the conversion from electricity to heat.
Stand-alone unit simplifies integration
Our technologies are designed as stand-alone units that limits modification needs of customer’s facilities and minimize downtime of the customer’s plant during the construction period. Simpler integration reduces capex and project risk.
Safe and cost-effective handling of solvent
Our proven and safe HPC (hot potassium carbonate) solvent is relatively cheap and available globally. This is different to Amines, where emitters may be locked in with one expensive solvent supplier. In addition, HPC offers superior HSE (health, safety and environment) and easier permitting.
Stockholm Exergi - One of the world’s largest BECCS projects
On March 27, 2025, Stockholm Exergi made final investment decision (FID) to build one of the world’s largest facilities for capture and permanent storage of biogenic CO₂ at their biomass-powered combined heat and power (CHP) plant Värtaverket in Stockholm, Sweden, with a full-scale deployment of 800,000 tonnes of CO₂ per year. The facility is scheduled to begin operations in 2028.
Stockholm Exergi has been awarded EUR 180 million by EU, and has signed permanent carbon removal agreements with Microsoft and the Frontier fund.Â
With the first FID for a large-scale project with Capsol’s technology now in place, this is set to further de-risk technology decisions and accelerate commercial traction.
