Enabling CO2 capture from coal power plant using membranes

Bloggers: Simon Roussanaly and Rahul Anantharaman

Electricity generation from coal represents respectively 41 and 30% of the world and European electricity generation. In this perspective, CCS is considered to be a promising way to reduce CO2 emissions from power production and therefore decrease the climate impact of power generation across the world.

Promising technologies for CO2 capture such as membranes are been investigated in the BIGCCS Centre. As part of this work, a new approach to design and optimization of membrane-based CO2 capture, called the «attainable region approach», which lead to more energy and cost efficient processes, has been developed by Karl Lindqvist, Rahul Anantharaman, and Simon Roussanaly from SINTEF Energy Research.

Based on this work, SINTEF has initiated collaboration with Carnegie Mellon University (Pittsburgh PA, USA) which is one of the top US universities. The aim of this collaboration is to use the new approach developed by SINTEF to identify the membrane properties required to obtain membrane-based CO2 capture processes which are able to compete in terms of cost with commercial technology. As part of this collaboration, Simon Roussanaly, researcher at SINTEF Energy Research, is currently visiting for seven weeks Haibo Zhai and Edward Rubin, both professors at Engineering and Public Policy department of Carnegie Mellon University. The results of the collaboration will be presented at the 2015 Pittsburgh Coal Conference and will also result in a journal article.
