German researchers ready to scale new DAC system

Successful trials prove reliability of system using waste heat to reduce power consumption, says Centre for Solar Energy and Hydrogen Research Baden-Wuerttemberg

German research institute the Centre for Solar Energy and Hydrogen Research Baden-Wuerttemberg (ZSW) is preparing to deploy a new highly efficient direct air capture (DAC) technology at industrial scale from 2025 after a pilot project proved its reliability by operating for more than 10,000 hours. One of the system’s key advantages is its lower power consumption of about 1kWh/kg of CO₂. This is achieved by using thermal energy such as waste heat from electrolysers or fuel synthesis to drive the CO₂ separation process. The process also delivers “consistently” high CO₂ quality, ZSW said. 1,000t/yr – Capacity at scale “Our technology has many advantages: it is extremely robust, efficien
