AEP Alstom Mountaineer

Project Overview

American Electric Power (AEP) and Alstom have teamed up to bring Alstom’s chilled ammonia process for CO2 capture to full commercial scale of up to 200 MW by 2011. This is a major step in demonstrating post-combustion carbon capture. The technology has the great advantage versus other technologies of being fully applicable not only for new power plants, but also for the retrofit of existing coal-fired power plants. The project will be implemented in two phases. This first phase, Alstom and AEP will jointly develop a 30 MWth product validation plant that will capture CO2 from flue gas emitted from AEP’s 1300 MW Mountaineer Plant located in New Haven, West Virginia. It is targeted to capture up to 100,000 tonnes of carbon dioxide (CO2) per year. The captured CO2 will be designated for geological storage in deep saline aquifers at the site. This pilot is scheduled for start-up at the end of 2008 and will operate for approximately 12-18 months.
