RepAir

What RepAir does

RepAir Carbon is an Israeli climate technology company founded in 2020 that develops solid-state electrochemical Direct Air Capture (DAC) technology targeting both atmospheric CO2 (approximately 400ppm) and diluted industrial point-source emissions (0-5% concentration). The company's core product, branded ElectraStack, is a modular architecture of hundreds of interlocking electrochemical cells inspired by battery technology, manufactured from abundant and recycled materials including nickel electrodes and injection-molded recycled polymers. The system captures and concentrates CO2 in a single continuous step at ambient temperature using only electricity, claiming 70% lower energy consumption (0.5-0.6 MWh/tonne) than conventional DAC methods and producing 98-99% pure CO2 output suitable for permanent storage or utilization as feedstock for sustainable fuels.

RepAir serves industrial emitters with diluted CO2 streams (gas turbines at 3%, aluminum smelters at 1%) and CDR buyers across aviation, shipping, automotive, and financial services seeking verified permanent carbon removal. The company operates a multi-channel revenue model: hardware/equipment sales of capture systems to DAC hub developers, milestone-based development funding from strategic partners (notably up to $3M from Shell and Mitsubishi for the Pelican DAC Hub in Louisiana), sale of high-quality CDR/DACS carbon removal credits, and CO2 feedstock sales for downstream Sustainable Aviation Fuel, e-methanol, and alternative plastics production. The business is pre-commercial with TRL 6 demonstrated in November 2023 and a commercial demonstrator targeted for 2025.

The company has assembled a strategic investor and partner base including Shell, Mitsubishi, Equinor, Ormat, Repsol, Extantia Capital, and Taranis Carbon Ventures, complemented by non-dilutive funding from the Israel Innovation Authority (5M NIS total) and the European Innovation Council (€12.5M). Operations span Israel (headquarters), the United States (RepAir Carbon US Inc. in Florida), and Luxembourg (European headquarters opened March 2026), with active DAC hub projects in the US (Pelican/Louisiana), France (C-Questra), Greece (EnEarth), and Kenya (Cella). Total disclosed funding exceeds $25M plus €12.5M in EIC blended capital.

Revenue model

1. DAC Technology Equipment Sales: RepAir sells its electrochemical carbon capture systems as equipment to project developers and industrial emitters. The company positions itself as a key equipment supplier for DAC hub projects, providing modular capture units for deployment.
2. Carbon Dioxide Removal Credits: RepAir generates revenue through the sale of high-quality carbon removal credits (CDR/DACS credits) to corporate buyers seeking to offset Scope 3 emissions. The company partners with storage providers (Cella, C-Questra, EnEarth) to offer verified permanent carbon removal credits.
3. Project Development Milestones: Receives milestone-based development funding from strategic partners (Shell, Mitsubishi) contingent on achieving project deliverables. This provides non-dilutive capital during technology deployment phases.
4. CO2 Feedstock Sales: Captured CO2 is sold as feedstock for sustainable production including Sustainable Aviation Fuel (SAF), e-methanol for maritime transport, and alternative plastics for automotive applications.

Core offering

RepAir develops and manufactures modular electrochemical carbon capture systems (the ElectraStack platform) that capture CO2 from low-concentration industrial emissions (0-5%) and atmospheric air (400ppm). The solid-state technology operates at ambient temperature using only electricity, consuming 70% less energy than conventional DAC methods and producing 98-99% pure CO2 for permanent storage or utilization as feedstock for sustainable fuels and materials. The company sells its capture units to enterprise industrial emitters, energy majors, and DAC hub developers for deployment in point-source capture and direct air capture projects globally.

Product overview

RepAir Carbon offers a unified technology platform centered on its proprietary electrochemical carbon capture system, branded as the ElectraStack. The platform is designed to capture CO2 across the full concentration spectrum—from diluted point source emissions (0-5%) to atmospheric air (400ppm)—using the same solid-state electrochemical technology. The core ElectraStack product serves as the modular building block that scales from pilot demonstrations to gigaton-level deployment. Supporting solutions include Direct Air Capture (DAC) for carbon dioxide removal, Diluted Point Source Capture for industrial emitters, Carbon Dioxide Removal and Storage (DACS) for permanent geological sequestration, and CO2 Feedstock for sustainable fuel and materials production. The company operates as an Israeli startup with global deployment capabilities across the US, Israel, and Europe.
