CO₂ injection pumps/compressors (system for carbon dioxide capture and storage (CCS))

How to reduce carbon dioxide (CO₂) is a challenge we face when we envision the global environment in the future. Needless to say, waste separation and recycling efforts at home are important, but more than 60% of Japan's carbon dioxide emissions come from factories, including power plants, steel mills, and chemical plants. Unless we focus on this aspect, initiatives outlined in the SDGs will be insufficient.
As part of our initiatives to contribute to creating a decarbonized society, we are promoting activities to reduce CO₂ through carbon dioxide capture and storage (CCS) and we continue to take on the challenge of CO₂ emissions and the future of human society.

CCS refers to a series of processes in which CO₂ generated by heavy industries is captured, not released into the atmosphere, and transported and stored in places (underground) with little impact on the global environment. When CO₂ is injected into the geological layer, it is necessary to increase the pressure of CO₂. A high resistive pressure deep underground requires extremely high pressure to inject CO₂ into it.
A compressor, or rotating machinery that compresses gas is used to increase the pressure of CO₂. This machine is indispensable for increasing the pressure of the recovered CO₂ to convert it to supercritical fluid that has interim properties between a liquid and a gas when exceeding the critical point (pressure approx. 7.4 MPa, temperature approx. 31°C). In addition to the compressor, the pump, a machine that further increases the pressure of the supercritical fluid, is also effective in storing CO₂ underground in a high-pressure supercritical state.

EBARA, as one of the few manufacturers in the world with the technology and experience in both compressors and pumps, is working to promote and expand CCS. Furthermore, the combination of CO₂ compressors and CO₂ injection pumps enables more efficient operation, contributing to the reduction of environmental impact.
CCS, a technology to curb global warming, is expected to expand further as a last resort for decarbonization. Leveraging its technology in the field of compressors and pumps, EBARA is committed to the social implementation of CCS technologies and a sustainable future.
