- Stockholm Exergi announced plans to build one of the world's largest carbon capture facilities using CATACARB Enhanced Hot Potassium Carbonate technology. - The facility aims to capture and permanently store around 800,000 tons of carbon dioxide annually, with operations set to begin in 2028. - Stockholm Exergi provides energy and heat to over 800,000 residents in the Stockholm area by burning sustainable wood and sawmill residues, which also emit significant carbon dioxide. - CATACARB and Stockholm Exergi have collaborated since April 2021, focusing on the design of the carbon capture core section. - CATACARB technology has over 200 licensed applications globally and utilizes a comprehensive database built over 60 years to optimize design and client support. - Enhanced HPC technology from CATACARB improves efficiency, reduces capital and operational costs, and allows for a smaller construction footprint. - Gary Buckholz, CEO of CATACARB, emphasized the technology's environmental and health benefits, noting the absence of carcinogens in the process. - The project is supported by the EU Innovation Fund and the Swedish government, showcasing a commitment to advancing carbon capture in the energy sector. - CATACARB's technology is versatile and applicable to various industries that emit flue gas, including power, steel, cement, pulp and paper, and petrochemicals.

Stockholm Exergi to begin building one of the world's largest carbon capture projects using CATACARB® Enhanced HPC:


LAWRENCE, Kan., April 1, 2025 /PRNewswire/ -- With technology licensed from CATACARB, Stockholm Exergi (SE) announced its decision to proceed building one of the world's largest facilities for capture and permanent storage of carbon dioxide. Operations are planned to begin in 2028.

CATACARB Enhanced Hot Potassium Carbonate (HPC) technology, design, and support will help SE to capture and permanently store approximately 800,000 tons of carbon dioxide per year. SE provides energy and heat to more than 800,000 people in the Stockholm area from burning wood and sawmill residues, such as wood chips, branches, and treetops. While sustainable, this process also releases a significant amount of carbon dioxide into the atmosphere.

CATACARB and SE have been collaborating since April 28, 2021, and working closely with SE's chosen detailed engineering firms to design the core section responsible for capturing carbon dioxide. While capturing carbon dioxide from flue gas is a newer application, CATACARB technology is already proven with over 200 licensed applications in 34 countries. CATACARB leverages its extensive database amassed from over 60 years of custom-designed plants along with ongoing collection of operational information in order to continually optimize design and support for new and existing clients. CATACARB licenses and designs both Basic HPC and Enhanced HPC, which utilizes additives to decrease capital and operational expenditures through improved efficiency, more flexibility in construction materials, and smaller construction footprint.

"The choice of CATACARB Enhanced HPC technology by Stockholm Exergi is notable not only for the financial advantages, but also because the technology prioritizes health and environment," said Gary Buckholz, CEO of CATACARB. "Unlike some competing technologies, there are no carcinogens formed in the process. Stockholm Exergi, with help from the EU Innovation fund and the Swedish government, is on an admirable path. We are proud to have joined them and provide continued support. We hope to help others in the industry rise to the challenge of carbon capture with confidence."
