RepAir Carbon raises $15M to commercialize breakthrough technology
Electrochemical solution slashes energy required for carbon capture by 70%, targeting the untapped one-gigaton market for diluted emissions from data centers
Tel Aviv, Israel, April 24 2025: RepAir Carbon, developer of an ultra energy-efficient electrochemical carbon capture solution, has secured $15 million in Series A extension funding. The round was co-led by Taranis Carbon Ventures and Extantia Capital, with participation from renewable energy player Ormat Technologies, and Repsol. The Israeli Innovation Authority also provided a non-dilutive $3 million grant as part of the round.
RepAir's proprietary technology addresses carbon reduction's biggest challenge by efficiently capturing dilute CO₂ from sources like gas turbines, aluminum smelters, and atmospheric air. Its fully electric, heat-free electrochemical system consumes 70% less energy than conventional methods by capturing and concentrating CO₂ in a single step, without the energy-intensive thermal processes or chemical solvents that make traditional approaches prohibitively expensive for diluted emissions.
This investment comes amid forecasts that AI will drive a 165% surge in data center energy demand by 2030, potentially generating 3.4 billion metric tons of CO₂ annually by 2040 if carbon intensity remains unchanged. Energy availability is becoming a critical constraint for AI growth, while hard-to-abate industries like cement, steel, chemicals, and aluminum simultaneously face intensifying pressure to implement viable decarbonization solutions to meet 2050 targets.
"Companies are starting to recognize that renewable energy alone cannot meet the unprecedented surge in energy demand driven by AI," said Amir Shiner, CEO and Co-founder of RepAir Carbon. "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. This funding will accelerate our manufacturing capabilities and technology deployment, allowing us to capitalize on these partnerships and scale our impact across multiple industries."
"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," said Victor Choley of Taranis, who joins RepAir's board of directors alongside Yair Reem from Extantia. "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."
RepAir's continuous electrochemical process eliminates the need for liquids, solvents or hazardous materials, allowing for a compact, modular design that can be mass-manufactured at scale using low-cost materials. The new capital will accelerate RepAir's path to commercial-scale manufacturing, focusing on engineering, production capabilities, and strategic demonstration projects with key industry partners.
"The Carbon Dioxide Removal market is still developing and currently relies heavily on voluntary purchases," added Yair Reem, Partner at Extantia. "RepAir's ability to deliver cutting edge solutions for point source as well as direct air capture is a real advantage, with very limited competition in scenarios where CO₂ is diluted below 5% concentration. Their highly modular, mass-manufacturable technology enables major industrial emitters to address emissions at the source without the massive energy investments required by traditional approaches – effectively creating an entirely new market that wasn't commercially viable until now."
This funding follows key commercial milestones for RepAir, including selection for the Pelican DAC project in Louisiana and a pioneering partnership with C-Questra to develop Europe's first onshore Direct Air Carbon Capture and Storage project in France, positioning the company at the forefront of the rapidly evolving carbon capture technology sector.
