🌱New Battery-Based CO2 Capture Device Cuts Costs
Cheaper CO2 capture tech could change the game
TL;DR
Researchers unveiled a battery-based CO2 capture device that uses less energy and costs less than existing tech. It could make carbon capture more viable for industries and startups.
Researchers have developed a battery-based CO2 capture device that slashes costs and energy use compared to existing methods. This device uses a reversible chemical reaction to capture CO2 and then release it, all powered by electricity. The tech requires just 0.8 megawatt-hours per ton of CO2 captured, a significant improvement over current methods which range from 1.5 to 3 megawatt-hours per ton. For startups and industries looking to reduce their carbon footprint, this could be a game-changer, especially as costs drop to $92 per ton for larger-scale operations.
Key Points
Battery-based CO2 capture device uses 0.8 megawatt-hours per ton of CO2 captured, compared to 1.5-3 MWh for current methods.
Estimated cost for a small pilot plant is $566 per ton of CO2 captured, dropping to $92 per ton for larger-scale operations.
Device uses a reversible chemical reaction to capture and release CO2, powered by electricity.
Lab-scale device tested with nine cells stacked together, demonstrating the viability of the technology.
Study published in Nature Energy in 2026, DOI: 10.1038/s41560-026-02129-z.
Why It Matters
If you're a startup or company looking to reduce your carbon footprint, this new CO2 capture tech could be a game-changer. It uses less energy and costs less than existing methods, making it more viable for smaller operations. For larger-scale operations, the cost drops to $92 per ton, making it economically feasible to capture CO2 on a larger scale.
