The high concentration of greenhouse gases (GHG) in the atmosphere leads to severe Climate Change and interlinked consequences, such as the rise of sea level, an increase in the average global temperature, reductions in dry-season rainfall in several regions, droughts and severe dust storms. The GHG emissions are mainly generated because the demand for services and goods as the living standards and global population augment. We must find ways that allow us to reduce the emissions and, at the same time, keep up with the demand for products and services.

Carbon Capture, Utilisation and Storage (CCUS) technologies are potential solutions for reducing CO2 emissions, the most significant. The project will focus on the post-combustion capture of CO2 of industrial flue gases using hydrotalcite (HT) as adsorbent. HT is a solid material, in contrast with mono-ethanolamine (MEA), a solvent currently used. It is expected that HT will be suitable for CO2 capture at high pressure and high temperature, an advantage over MEA. Using experimental information from partner Universities, a model will be developed and validated.

Later on, the model will be used as base for a technical and economical assessment of the process to determine its efficiency and feasibility.
