CO2 Technology Centre Mongstad (TCM) and Alstom have agreed to extend their cooperation and will continue testing Alstom’s proprietary Chilled Ammonia process for another year at the Mongstad site in Norway.

The Chilled Ammonia process is seen as a promising carbon capture technology, offering the potential of commercially viable carbon capture and storage (CCS). 

The two companies will now continue testing until autumn 2014.

This follows a successful first year of operation of the Norwegian carbon capture test facility. Alstom is presently one of two the key technology partners in the project developed by state-owned CCS enterprise Gassnova, as well as oil giants Shell, Statoil and Sasol.

The TCM facility, located north of Bergen on the Norwegian west coast, is the world’s largest CO2 capture test centre, investigating several high-tech ways of capturing CO2 generated by industry – to reduce emissions and protect the environment. The Norwegian Government recently strengthened its support for TCM by providing it with an additional NOK 400 million ($67.7m) for carbon capture technology testing over the next four year.


The ‘Chilled Ammonia Process’ (CAP) method offers environmentally-friendly carbon capture, with the process based at TCM using industrial flue gases from both a nearby Combined Heat and Power plant (CHP) and Statoil’s Mongstad refinery.

With real flue gases to work with, the team has been able to test the CAP principles under ‘live’ conditions, collect valuable data, and improve the process.

“The testing they have completed to date has already contributed greatly to the commercialisation of the Chilled Ammonia process…”

Frank Ellingsen, Managing Director, TCM

Andreas Lusch, Senior Vice-President of Alstom’s Steam business, said, “This is a great illustration of how Alstom is at the global forefront of CO2 reduction. Our involvement here in the TCM partnership demonstrates our strong commitment to developing more efficient, more effective and more affordable ways of cutting carbon dioxide emissions and generating cleaner electricity.”

Frank Ellingsen, Managing Director, TCM, described the potential as he added, “It is very exciting that Alstom is continuing to test and verify its technologies here at TCM. The testing they have completed to date has already contributed greatly to the commercialisation of the Chilled Ammonia process and the next phase of testing will continue to assess the viability of the technology providing Alstom with a valuable head start in the decarbonisation technology market.”

Two technology demonstrations have been overlaid onto TCM’s core utility infrastructure; which provides access to 100,000 tonnes per year of simulated coal and gas-fired CO2 flue gases; from a gas-fired Combined Heat and Power plant (CHP) and a refinery cracker.

The key achievements from the Amine and Chilled Ammonia plant include gaining operational experience from more than 7,000 hours of testing with more than 90% of uptime.
