RepAir Raises $15 Million to Scale Electromechanical Carbon Capture Solution

RepAir announced that it has raised $15 million in a Series A funding round, with proceeds to be used to commercialize the company’s electromechanical solution designed to remove atmospheric and industrial emissions at low cost at scale.

Founded in 2020, Israel-based RepAir offers a modular, scalable solution that can capture carbon from diluted sources, and can be utilized across multiple applications including direct air capture (DAC) and point source industrial emissions, without the use of heat, liquids, or solvents. The electromechanical solution works by placing cathode and anode electrodes on either side of a separator plate, with atmospheric air drawn into the cathode, and applying an electrical current to generate hydroxide ions on the surface of the cathode, which bind with CO2 molecules which cross the separator to the anode, with the remaining air returned to the atmosphere.

According to RepAir, the process consumes 70% less energy compared to conventional carbon capture methods, and can efficiently capture diluted CO2 from sources such as gas turbines, aluminum smelters, and atmospheric air, addressing key challenges to scaling industrial carbon capture solutions.

RepAir said that the new capital will be used to accelerate its path to commercial-scale manufacturing, focusing on engineering, production capabilities, and strategic demonstration projects with key industry partners.

Amir Shiner, CEO and Co-founder of RepAir Carbon, said:

"Companies are starting to recognize that renewable energy alone cannot meet the unprecedented surge in energy demand driven by AI. We’re seeing major momentum in our conversations with aluminum producers, gas turbine manufacturers, and global OEMs operating gigafactories—all seeking solutions for the untapped gigaton CO₂ opportunity from diluted emissions that existing technologies can’t efficiently address."

The funding round was led by Taranis Carbon Ventures and Extantia Capital, with participation from renewable energy company Ormat Technologies, and Repsol. As part of the round, the Israeli Innovation Authority also provided a non-dilutive $3 million grant.

Alongside the funding round, Taranis’ Victor Choley and Extantia’s Yair Reem joined RepAir's board of directors.

Choley said:

"The explosive rise of AI usage globally has dramatically increased energy demands, creating an unexpected and urgent need for carbon capture solutions that can work effectively with gas turbine power generation. RepAir’s ability to leverage the same core technology across both direct air capture and point source applications offers an incredibly promising pathway to meaningful emissions reduction and removal at unprecedented efficiency levels."
