RepAir Carbon has secured $15 million in Series A extension funding. The round was co-led by Taranis Carbon Ventures and Extantia Capital. Participating investors include Ormat Technologies and Repsol. The Israeli Innovation Authority provided a non-dilutive $3 million grant as part of the funding round.
RepAir’s proprietary technology efficiently captures dilute CO₂ from sources like gas turbines and aluminum smelters. Its ultra energy-efficient electrochemical system uses 70% less energy than conventional methods. It captures and concentrates CO₂ in one step, avoiding costly thermal processes and chemical solvents.
This investment comes as AI is projected to increase data center energy demand by 165% by 2030. If carbon intensity remains unchanged, AI could generate 3.4 billion metric tons of CO₂ annually by 2040. Energy availability is increasingly critical for AI growth and hard-to-abate industries.
Amir Shiner, CEO and Co-founder of RepAir Carbon, noted that companies recognize renewable energy alone cannot meet the surge in energy demand. He mentioned momentum in discussions with aluminum producers and gas turbine manufacturers. All are seeking solutions for capturing CO₂ from diluted emissions.
RepAir’s continuous electrochemical process eliminates the need for liquids or hazardous materials. This allows for a compact, modular design that can be mass-produced using low-cost materials.
The new capital will accelerate RepAir’s commercial-scale manufacturing and focus on strategic projects with industry partners. RepAir’s solutions for point source and direct air capture provide a real advantage. There is limited competition where CO₂ concentration is diluted below 5%.
Their modular technology enables industrial emitters to address emissions at the source without massive investment in traditional methods. This creates a new market that wasn’t commercially viable until recently.
