Air Liquide and B&W test new “oxy-coal combustion”


Testing is about to begin on an exciting new carbon capture scheme that hopes to cut greenhouse gases with an innovative use of liquid oxygen.

The project is being run by The Babcock & Wilcox Company (B&W), in collaboration with American Air Liquide Inc., and aims to produce a more efficient kind of coal-fuelled power station.

Tests will take place at the company’s Clean Environment Development Facility (CEDF) in Alliance, Ohio, a large-scale demonstration facility that has been used to develop emissions-control technology.

In this scenario the CEDF will be used to validate a technology called $quot;oxy-coal combustion$quot; that utilizes pure oxygen for the combustion of coal in electricity generating plants. In this system, nitrogen that comes in with the air for the combustion process is eliminated. As a result, the exhaust gas is a relatively pure stream of CO2 that is ready for long-term storage operations.
