The U.S. Department of Energy has announced that Ramgen Power Systems LLC, of Bellevue, Washington, has been awarded $20 million (US) in funding from the American Recovery and Reinvestment Act to scale up a device that uses supersonic shockwaves to compress carbon dioxide (CO2) for capture and storage.

The funding from DOE’s Office of Fossil Energy and its National Energy Technology Laboratory (NETL) will accelerate commercial deployment of the novel CO2 compressor, called the Rampressor, which can be used for carbon capture and storage in most industrial settings.

The Rampressor employs a fundamentally new technology that reduces the cost of compressing CO2 to achieve affordable carbon capture and storage. At the heart of this relatively simple device is a rotating disk that spins with enough speed to achieve supersonic compression effects in a stationary environment. Compared to conventional CO2 compressors, the Rampressor has fewer parts, a smaller footprint and lower overall system costs. In addition, the system generates higher quality heat, which can potentially be captured and used, further increasing the system’s efficiency.
