nov 10, 2025 - (POLAND) Chemet introduces solution for a rail-based CO₂ transport and storage in Europe

Description:

With carbon capture and storage (CCS) gaining importance in Europe’s transition toward a low-emission economy, the transport of captured CO₂ is emerging as a crucial element of the industrial value chain.

Chemet, a company headquartered in Tarnowskie Góry, Poland, has developed a complex, rail-based system for the transport of liquefied carbon dioxide (LCO₂), supported by its own designs for storage tanks and loading infrastructure.

A freight wagon for CO₂

At the core of Chemet’s solution is the new 62 m³ railway tank car for liquid CO₂. The wagon, certified under TSI 321/2013, has a tare weight of around 28 t and a maximum payload of 62 t, giving a total loaded weight of 90 t. It can reach 100 km/h when loaded and 120 km/h when empty.

The tank, built to withstand a test pressure of 2.6 MPa, is insulated with a 200 mm polyurethane layer and clad in stainless steel. It includes hydraulic bottom valves for both gas and liquid phases and a 500 mm manhole for operational access.
