Capsol Technologies has signed a cooperation agreement with Holcim Group, a global leader in innovative and sustainable building solutions. The agreement includes the delivery of a CapsolGo® carbon capture demonstration campaign at a plant in southern Germany as the first step in a broader collaboration aimed at decarbonizing Holcim’s global portfolio of industrial plants.
“This marks a significant milestone for Capsol Technologies as we initiate the demonstration of our CapsolEoP® technology at a Holcim cement plant. We are eager to collaborate closely with Holcim, showcasing our capability to contribute to their ambitious climate targets,” says Philipp Staggat, Chief Product Officer of Capsol Technologies.
Holcim Süddeutschland GmbH operates under the Holcim Group, which is present in around 60 countries and employs over 60,000 people. As part of its efforts to drive sustainability, Holcim has committed to deliver 8 million tons of fully decarbonized cement per year by 2030. With sustainability at the core of its strategy, Holcim has 2030 and 2050 net-zero targets validated by the Science Based Targets initiative.
“This cooperation with Capsol Technologies reflects our commitment to identifying and deploying the most suitable carbon capture technologies for reducing emissions. The CapsolEoP® (End-of-Pipe) unit’s design, requiring no external steam supply and exhibiting low energy consumption, makes it an attractive option for our Dotternhausen plant,” says Dieter Schillo, Plant Manager of Holcim (Süddeutschland) GmbH.
If the demonstration campaign at the Dotternhausen plant is successful, Holcim Group would consider deploying Capsol’s carbon capture technology based on the safe and proven Hot Potassium Carbonate (HPC) solvent at full-scale cement plants across multiple sites.
As part of this agreement, the CapsolGo® demonstration campaign at the Dotternhausen plant will be delivered as a turnkey solution, including testing and validation services to provide Holcim with critical data and insights on Capsol’s carbon capture technology.
This cooperation builds on an earlier engagement between the parties, including a feasibility study completed with Capsol Technologies by Holcim Group’s Aggregate Industries UK Ltd for its Cauldon cement plant in Stoke-on-Trent.
The delivery of the CapsolGo® unit is scheduled for Q2 2025, with testing set to commence in late Q2 2025. The project will span 4 months.
About CapsolGo® demonstration units
CapsolGo® demonstration projects are designed to provide emitters with carbon capture data using Capsol’s HPC-based process on their specific plants, supporting accelerated decision processes towards full-scale carbon capture.
A standard CapsolGo® demonstration campaign is offered on a rental basis, typically has a duration of six months, and includes transportation, installation, operation, and testing services.
Capsol’s HPC-based process is using potassium carbonate as the CO2 solvent, a process which is well-documented and used in more than 750 plants globally in multiple industries. A patented energy re-circulation process offers low capture cost and the flexibility to monetize heat and electricity.
