Innovation

Industry Problem

RepAir Carbon is addressing the urgent challenge of reducing billions of tons of CO2 emissions annually by developing innovative technologies for large-scale carbon capture and removal that are both economically viable and environmentally sustainable.

R&D Focus

RepAir’s R&D is centered on pioneering electrochemical carbon capture technology that drastically reduces energy use while enabling scalable, fully electric CO2 removal. Their niche lies in developing modular, solvent-free systems designed for efficient capture from both ambient air (direct air capture) and low-concentration industrial emissions, targeting gigaton-scale carbon removal with safe, cost-effective, and globally deployable solutions.

Innovative Solution

RepAir is solving the problem of high energy consumption and inefficiency in traditional carbon capture methods by developing a low-energy, fully electric, and scalable technology. It also addresses the challenge of capturing CO2 from both very dilute sources such as the atmosphere and low-concentration industrial emissions, providing safe, cost-effective, and environmentally friendly carbon removal at a gigaton scale.

Solution Effectiveness

RepAir’s electrochemical technology consumes 70% less energy than conventional carbon capture methods. It removes CO2 at 600 kWh per ton from direct air capture and just 300 kWh per ton from diluted industrial sources, with projected costs as low as $37 per ton for industrial emissions and $70 per ton for direct air capture at megaton scale, demonstrating significant energy and cost efficiency.

Products

Product

– StackDAC Module – Modular building blocks for RepAir’s electrochemical carbon capture technology, designed for scalable installation and mass manufacturing to capture CO2 efficiently at a gigaton scale. – Direct Air Capture (DAC) Solution – Captures CO2 directly from the atmosphere to remove historical and hard-to-abate emissions, providing permanent and verifiable carbon removal. – Point Source Capture Solution – Captures CO2 from diluted industrial emissions (e.g., aluminium smelting) at low concentrations with ultra-low energy consumption for industrial decarbonization. – Carbon Storage Projects (e.g., Olea, Oak, Acacia) – Large-scale CO2 storage projects in partnership with storage providers to securely and permanently sequester captured carbon underground, supporting carbon removal and credit generation. – Customer Reviews – NA

Star Product

StackDAC Module is the core innovation driving RepAir’s scalable carbon capture technology. Its modular, mass-manufacturable design allows for easy deployment at gigaton scale, making it highly efficient, cost-effective, and adaptable across diverse sites. This product enables RepAir to deliver their patented, low-energy, fully electric CO2 capture solution, positioning it as the foundation for their large-scale carbon removal impact.

Demo Product or Complete Product?

The Direct Air Capture (DAC) electrochemical dual-cell system prototype was unveiled as a field prototype in November 2023. This marks a major milestone with the technology reaching Technology Readiness Level (TRL) 6, meaning it has been demonstrated in an operational environment but is still in the development and testing phase before full commercial deployment.
