Carbon capture tech developer Capsol has partnered with decarbonization company Sumitomo to deploy a CO2 capture demonstration at a biomass-powered combined heat and power (bio-CHP) plant operated by Swedish power company Mälarenergi.
Coming off the heels of a previous Sumitomo and Capsol collaboration at Växjö Energi AB’s biomass plant, this demo, expected to launch this November, will be installed at Mälarenergi’s facilities in Västerås, Sweden.
Building on the experience gained from this demonstration, in the future, the partners will apply the acquired know-how towards a full-scale installation that, according to them, will be able to capture up to 400,000 tonnes of carbon dioxide annually.
As part of this collaboration, Sumitomo will provide the carbon capture facility, and Mälarenergi will manage onsite operations.
This initiative will utilize Capsol’s mobile CO2 capture unit that functions with the help of the Hot Potassium Carbonate (HPC) process, along with Capsol’s EoP® heat recovery technology.
When in contact with passing exhaust gasses, the HPC system captures CO2 with the help of a potassium carbonate solution. During this process, the carbon dioxide binds with the solution, forming a compound, which then gets heated to release pure CO2.
With a carbon capture rate as high as over 90%, their HPC system is able to produce high-purity CO2 that can be reused or stored away safely. The environmentally friendly design of this technology, based on a non-toxic potassium carbonate solvent, enables its usage in residential areas.

This decarbonization process also results in valuable byproducts, as it allows for the sustainable production of low-temperature heat.
Capsol’s licensed technology has already validated its feasibility through a series of demo partnerships with different biomass and energy-from-waste (EfW) plants in Europe.
Keeping in line with their commitment to accelerating the global transition towards net zero, Capsol’s carbon capture initiatives so far represent a total of over seven million tonnes of potential CO2 reductions per year across a network of different EfW and biomass facilities.
