Cool Planet Technologies aims to reduce the cost of removing carbon dioxide from industrial flue gas emissions. Their membrane-based technology can be used in various industries and applications, capturing up to 99% of carbon dioxide with high purity. The process is energy efficient, compact, and flexible, making it suitable for retrofit or new-build solutions. Cool Planet Technologies is collaborating with Holcim to decarbonize their cement plant in Germany. They have successfully piloted their technology in coal-fired power stations and are planning to operate demonstration plants with increasing capacities in the coming years. The company's membrane was developed by Helmholtz Zentrum Hereon, and their investors include ENI next, Audacy Ventures, and Neva SGR.
