RepAir, established in 2020 and based in Israel, develops electrochemical carbon capture technology applicable to direct air capture and point source emissions.

The company's electrochemical process operates at ambient temperature without thermal input or liquid solvents. Laboratory measurements indicate energy consumption of 0.6MW compared to the industry standard of 2.5MW for equivalent carbon capture capacity. The system demonstrates operational adaptability across varying CO2 concentration ranges.

The technology utilizes modular electrochemical cells constructed with nickel-based electrodes and ion-selective membranes. Manufacturing processes incorporate plastic injection molding techniques. The system maintains continuous CO2 capture capabilities at standard temperature and pressure, with documented CO2 output purity of 98%. The modular design facilitates integration with intermittent power sources through rapid system response characteristics.
