American Electric Power (AEP) and Germany’s RWE have signed a memorandum of understanding on the collaboration, and hope that it will help to reduce greenhouse gas emissions from coal-fired power generation.

Michael Morris, chairman, president and CEO of AEP, said: We’re extremely pleased that RWE will join us in this important step toward commercialization of carbon capture technology. By combining our engineering and operational expertise, I’m confident we can address any technological challenges presented by this project.

The Alstom technology will be installed on AEP’s 1,300MW Mountaineer plant in New Haven, West Virginia, where it will capture carbon dioxide from a slipstream of flue gas from the plant. The slipstream will be equivalent to 20MW of generation.

The Alstom chilled ammonia system is expected to capture up to 200,000 metric tons of carbon dioxide per year, which will be injected for geological storage in deep saline aquifers at the site.
