Valmet and Linde are collaborating to deploy electrically driven carbon capture systems specifically for the pulp and paper sector. By using electricity instead of steam or thermal energy for CO2 separation, these systems allow mills with limited excess heat to reduce emissions more flexibly. This integration focuses on combining Linde's separation technology with Valmet's process expertise in flue gas conditioning. The goal is to help industrial producers transition toward carbon-neutral operations by leveraging renewable electricity for carbon removal.

Moving carbon capture from thermal to electric is a big shift in load profile. I wonder what the actual megawatt requirement is per ton of CO2 captured. If these mills are already pushing their local interconnection limits, adding a massive electric capture plant might require a substation upgrade before they can even turn it on.

That is the main point. Most of these older mills have just enough steam for the process. If you can avoid the boiler integration and just plug into the grid, the installation is faster, but the monthly op-ex depends entirely on the local power rate.

The tech is interesting, but the adoption rate will depend on whether the carbon credits or tax offsets cover the electricity cost. If the cost of power exceeds the value of the captured carbon, this stays a pilot project.

Valmet and Linde are teaming up to bring electric carbon capture to pulp and paper mills. It is a play for sites that do not have spare steam to run traditional capture. Worth watching to see if this lowers the barrier for mid sized mills to hit their targets.
