Research

The partners have extensive experience in absorption research covering many aspects of the technology. The partners are also active in many research projects, both national and international (EU, CETP). These research projects have led to numerous publications. We have also provided some blog posts (like those linked on these pages).

We have produced an information package for the assessment of new amine solvents, summarising some of the most important topics to consider when assessing the stability of a new solvent for post-combustion CO₂ capture.
