Sumitomo SHI FW and Capsol Technologies demonstrate potential to capture up to 400,000 tons of CO2 at Mälarenergi’s bio-CHP plant in Sweden

November 6, 2024

Sumitomo SHI FW (SFW) and Capsol Technologies ASA (Capsol) announce a carbon capture demonstration campaign at Swedish Mälarenergi’s combined heat and power (bio-CHP) plant in Västerås, Sweden. The demonstration unit will commence operations in November 2024 as part of a rental agreement between SFW and Capsol.

Mälarenergi and SFW have signed an agreement under which SFW will provide a mobile carbon capture demonstration facility and Mälarenergi will host the corresponding operation activities at their biomass plant in Västerås, Sweden. The mobile carbon capture unit, delivered by Capsol, is based on the Hot Potassium Carbonate (HPC) process, incorporating the patented EoP® heat recovery technology by Capsol.

The demonstration campaign will provide valuable data on the performance of the technical solution for Mälarenergi’s specific flue gas conditions that can be used in optimizing the planned full-scale capture plant at Mälarenergi, which will reduce emissions by approximately 400,000 tons of CO2 each year.

Carbon capture has great potential to counteract the climate crisis. What we need to move forward with our investigative work is plant-specific knowledge of how the technology can be applied to the combined heat and power plant in Västerås, in the most resource-efficient and optimal way possible. That is what we are now going to investigate, practically and on site.

Niklas Gunnar CEO of Mälarenergi


The HPC process has a CO2 capture rate exceeding 90% and produces high-purity (<99%) CO2. The electricity-powered technology produces low-temperature heat, contributing to sustainable heat production and low energy penalty. The potassium carbonate solvent is safe and non-toxic, making the HPC solution eco-friendly and fit for residential areas.

In October 2023, SFW and Capsol entered into an agreement for the delivery of two CapsolGo® demonstration campaigns to be executed within SFW’s global client base. The companies have already conducted one testing campaign at Växjö Energi AB’s biomass plant in Sweden.

SFW and Capsol continue close cooperation in the Nordics, developing and demonstrating innovative, concrete ways to mitigate climate change.
