Celle, December 2025. With the ramp-up of Carbon Capture and Storage (CCS) and Carbon Capture and Utilization (CCU), the first CO2 pipeline networks, compression stations, storage facilities, and industrial process chains are emerging across Europe, presenting entirely new requirements for materials, leak-tightness, and the design of metal-seated valves. Hartmann Valves demonstrates how CO₂ projects can be realized safely, efficiently, and sustainably based on over 75 years of experience, technical expertise, and proven solutions from high-pressure and energy technology applications. The product portfolio is being strategically expanded to include welded high-integrity shut-off valves and optimized wellheads for CO2 transport, CO2 storage, and CO2 processing.
Safely Storing CO₂ – Carbon Capture and Storage (CCS)
In CCS, CO₂ is captured, compressed, transported, and permanently stored underground. The integrity of the entire system—from capture through high-pressure pipelines to the wellhead and into the reservoir—is critical. Hartmann Valves offers project-specific wellheads and metal-seated valves designed for demanding pressure and temperature ranges, ensuring reliable shut-off.
“Safety and leak-tightness are our top priorities. Our metal-seated valves are designed for applications under extreme conditions and ensure reliable shut-off, even with supercritical CO₂,” explains Werner Hartmann, Managing Director of Hartmann Valves. “We are strategically applying our decades of development and manufacturing experience in high-pressure and specialty valves for hydrocarbons to CO₂ storage technologies.”
Corrosion-resistant materials such as nickel-based alloys and high-strength steels prevent leaks and material aging. Complemented by precise monitoring, risks and operating costs can be significantly reduced.
Utilizing CO₂ as a Raw Material – Carbon Capture and Utilization (CCU)
In addition to safe storage, the utilization of CO₂ as a valuable raw material is gaining increasing importance. In processes such as methanol or e-fuel synthesis, urea production, concrete curing, or as a refrigerant (R744) in large heat pumps, CO₂ is part of closed process chains with high demands on pressure retention and leak-tightness. Here, Hartmann Valves’ technical experience from high-pressure, gas, and chemical applications comes into play.
Hard-coated seating surfaces made of tungsten or chromium carbide, precision-manufactured ball-seat pairs, and robust actuation systems ensure permanently reproducible leak-tightness, even with frequent switching cycles and changing operating conditions, such as extreme pressure fluctuations. “We are consistently applying our expertise in metal-seated valves and high-pressure systems, developed over many years, to the requirements of future CO₂ infrastructures. This enables us to create reliable solutions for safe and efficient CO₂ transport and storage systems,” emphasizes Christian Hartmann, Managing Director responsible for Research & Development at Hartmann Valves.
The company benefits from its experience handling CO₂ in the fields of oil and gas production, refineries, chemicals, and geothermal energy, where CO₂ is used, for example, as a scaling inhibitor.
