ESCAP™ is an energy-saving CO₂ absorption process that enables the separation and recovery of high-purity CO₂ from gases including CO₂, using significantly reduced amounts of energy.

ESCAP™ achieves a greater than 40% reduction in the level of heat consumption required for the separation and recovery of CO₂ compared to conventional technology. This enables the production of high-purity CO₂ from source gases with high levels of impurities, for applications including food use.

In addition to food use, this technology is suitable for making chemical raw materials, removal of CO₂ in chemical processes, EOR (Enhanced Oil Recovery), and CCS (Carbon Capture & Storage).

It is based on an energy-saving carbon dioxide recovery technology developed under the NEDO-sponsored research project COURSE50 (CO₂ Ultimate Reduction in the Steelmaking process by innovative technology for cool Earth 50), commercialized for industrial application with the addition of NIPPON STEEL ENGINEERING CO., LTD. proprietary technology.
