Carbon Capture
Nanomaterials for CO2 capture and sequestration
Sky Nano
Knoxville, United States
Sky Nano, founded in 2017 in Knoxville, Tennessee, represents a groundbreaking convergence of environmental sustainability and advanced nanotechnology. The company has developed a revolutionary process that transforms carbon dioxide, a harmful greenhouse gas, into high-value carbon nanotubes, effectively turning an environmental liability into a valuable industrial asset. This innovative approach addresses two critical global challenges simultaneously: climate change mitigation and the growing demand for advanced nanomaterials. Sky Nano's proprietary technology uses carbon dioxide as the primary feedstock for producing multi-walled carbon nanotubes through a novel electrocatalytic process. Unlike traditional carbon nanotube manufacturing methods that rely on fossil fuels and generate significant CO2 emissions, Sky Nano's process actually consumes CO2, making it carbon-negative. The resulting carbon nanotubes exhibit exceptional mechanical strength, electrical conductivity, and thermal stability, making them ideal for applications in batteries, composites, conductive additives, and advanced materials. The company's technology has significant implications for the battery industry, where carbon nanotubes can enhance electrode performance, increase energy density, and improve charge-discharge rates in lithium-ion batteries. Sky Nano has secured over $10 million in funding from investors and government grants, reflecting strong confidence in its dual value proposition of environmental benefit and commercial viability. The company's approach exemplifies the principles of carbon capture and utilization, transforming waste CO2 from industrial sources into valuable products. As global demand for carbon nanotubes continues to grow across electronics, energy storage, and composite materials sectors, Sky Nano's sustainable production method positions it as a pioneer in green nanotechnology manufacturing and a significant contributor to the circular carbon economy.
