“With this agreement, we’ve now signed five offtake contracts with Louisiana customers and are continuing to scale our one-of-a-kind CCS system, the largest in the world,” said Barry Engle, President of ExxonMobil Low Carbon Solutions. AtmosClear’s Baton Rouge BECCS plant will be fuelled with “sustainable materials like sugarcane bagasse and products from responsible forest management” to produce clean power while capturing 680 000 metric tons of biogenic carbon dioxide per year for sequestration or utilisation, eg as feedstock for low-carbon natural gas or other synthetic fuels.
Copenhagen considers Large scale BECCS is also under consideration in Greater Copenhagen, where the public utility HOFOR has signed a joint development agreement with Drax subsidiary Elimini, a “carbon removal expert with a mission to remove carbon for good.” The BECCS plan envisages installation of carbon capture at Copenhagen’s Amagerværket combined heat and power plant. The agreement covers the development of the BECCS facility, with the aim of entering into a joint venture agreement to transform unit 4 (AMV4) at the Amagerværket site to capture CO2

high-quality, verified carbon removal credits in addition to renewable electricity and heat. The Amagerværket power plant, which yearly produces about 25% of Copenhagen’s district heating using biomass while generating 670 GWh of renewable electricity, is one of Denmark’s largest point sources of biogenic CO2
. HOFOR
has an established biomass supply chain to purchase certified sustainable wood pellets and wood chips. The project intends to establish a full BECCS value chain with the capability to remove carbon dioxide from heat and power production at the facility totalling hundreds of thousands of tonnes annually, supporting Copenhagen’s ambition of being climate positive by 2035. The project is among ten pre-qualified projects that are eligible for the Danish Energy Agency’s CCS subsidy scheme.
The Danish government recognises that capture and storage of biogenic CO2
is an
effective tool to fight climate change and key to achieving national and international climate ambitions. In line with Denmark’s goals, in 2024 the Danish Energy Agency established a USD
4.2 billion CCS fund to support the development of capture, transportation and geological sequestration of CO2
over a 15-year period.
In parallel, Elimini and HOFOR have agreed a CDR marketing agreement under which Elimini will lead the commercialisation pathway for the project’s verified carbon removal credits.
KEZO opts for hot potassium carbonate
Elsewhere in Europe, Zurich Oberland waste management company KEZO, is deploying CATACARB’s Hot Potassium Carbonate (HPC) capture technology at a pilot carbon capture unit installed at KEZO’s Hinwil waste-to-energy plant in Switzerland.
The project is being developed in collaboration with Sulzer. CATACARB has licensed its proven capture technology and provided the process
design package — able to achieve 90% CO2 capture, with guaranteed performance thanks to “rigorous testing.”
The CATACARB HPC process is said to be well suited to challenging flue gas conditions, with the operational flexibility to deal with “intermittent waste feed and variable temperatures.” The KEZO pilot aims to demonstrate steady capture efficiency, simplified solvent management focused on health and safety, and reduced overall energy demand compared with amine-based alternatives.
The comprehensive operational data collected from this pilot will shape KEZO’s commercial deployment while supporting its commitment to pragmatic, technology-driven decarbonisation, the company says. KEZO expects the results to inform stakeholders about viable carbon capture management options for the waste-to-energy sector and to guide decision-making on next steps for wider implementation in partnership with Sulzer.
The CATACARB company is owned and operated by USA-based Eickmeyer & Associates, Inc.
