CO₂ Injection Pump/Compressor (for CCS (Carbon Dioxide Capture and Storage) Systems)

"CCS (Carbon Dioxide Capture and Storage)" technology to put a stop to climate change "CO₂ injection pump/compressor" will change the future

Tackling CO2 reduction with CCS (Carbon Dioxide Capture and Storage)

How to reduce carbon dioxide (CO2) is a challenge we face when considering the future of the global environment. While household trash separation and recycling efforts are of course important, over 60% of Japan's carbon dioxide emissions are emitted from power plants, steel mills, chemical factories, and other factories, and overlooking this aspect would make it difficult to fully address the SDGs.
As one of our measures to contribute to a decarbonized society, we are working to reduce CO2 through CCS (Carbon dioxide Capture and Storage), and we continue to take on the challenge of looking ahead to the future of CO2 and human society.

 

Compressors and pumps essential for CCS

CCS refers to the process of capturing CO2 generated by heavy industry and other sources, preventing it from being released into the atmosphere, and transporting and storing it in a location (underground) that has minimal impact on the global environment. When injecting CO₂ into geological formations, the CO₂ needs to be pressurized. Deep underground, there is high resistance pressure, so extremely high pressure is required to inject CO₂ there.
To increase the pressure of CO₂, a compressor, a rotating machine that compresses gas, is used. This machine is essential for pressurizing the captured CO₂ into a "supercritical fluid," which has properties intermediate between a liquid and a gas and exceeds its critical point (a pressure of approximately 7.4 MPa and a temperature of approximately 31°C). In addition, in underground storage of CO2, which is in a high-pressure supercritical state, in addition to compressors, pumps, which are machines that further increase the pressure of the supercritical fluid, are also effective.

Ebara's two technologies contribute to the spread of CCS

As one of the few manufacturers in the world with the technology and track record in both compressors and pumps, EBARA is working to promote the spread and expansion of CCS. Furthermore, by combining a "CO₂ compressor" and a "CO₂ injection pump", more efficient operation is possible, contributing to reducing the environmental burden.
"CCS", a technology that puts a stop to global warming, is expected to expand further in the future as a trump card for decarbonization. With its compressor and pump technologies, EBARA will continue to work towards the widespread adoption of CCS in society and the realization of a sustainable future.
