GreenCap Solutions has announced the launch of a demonstration project to test its carbon capture technology in primary aluminium production. The initiative targets the challenge of capturing CO₂ from low-concentration point sources, one of the most significant hurdles in the aluminium industry.

The direct emissions of CO₂ from the electrolysis process in primary aluminium production is approximately 1.5 kg of CO₂ per kg of liquid aluminium. However, the low concentration of CO₂ in the flue gases, around 1 percent, poses a major obstacle to effective capture. GreenCap will validate its novel carbon capture technology in collaboration with Norwegian aluminium and renewable energy company Hydro.
“We are very excited to partner with Hydro to advance our carbon capture technology for industrial applications. This collaboration aligns perfectly with our strategy to collaborate with reputable industry leaders to scale our unique solutions”, says Ronny Bergerud, COO at GreenCap Solutions.
GreenCap’s carbon capture process is based on physical adsorption using a solid sorbent, without the use of chemicals. The technology is energy-efficient, modular, and well suited for low-concentration sources. It has already been demonstrated in practical operation through Direct Air Capture (DAC) units and applied in CO₂ recovery solutions in agriculture, as well as in industrial applications requiring CO₂-free air.
“We need a cost-efficient solution to capture the process emissions from our primary aluminium plants, and we pursue several pathways of technology development to find the best one. GreenCap’s current demonstrators and their great work so far show that their solution has promising potential, and we are eager to test it as one of several carbon capture technologies now being evaluated for industrial-scale application,” says Morten Landsgård, Head of Electrolysis Decarbonization of Hydro Aluminium Metal.
The project aims to verify the performance of GreenCap’s capture technology against real flue gas streams from industry, and to reduce risk ahead of full-scale implementation. A key objective is to document how impurities in the flue gas affect material performance and CO₂ capture efficiency.
The project is carried out in the period between May 2025 and May 2026. It is supported by Norwegian state enterprise Gassnova through the CLIMIT program, which promotes the testing, verification, and scaling of new carbon capture technologies.
