The U.S. Air Force has recently awarded a $1.25 million contract to the innovative startup SkyNano, marking a significant leap forward in the advancement of carbon nanotube technology derived from carbon dioxide. This strategic investment reflects the military branch’s commitment to accelerating the development of low-cost, battery-grade graphite materials critical to next-generation energy storage solutions. SkyNano, a company led by Innovation Crossroads alumna Anna Douglas, is pioneering a transformative process that converts CO2, a prevalent greenhouse gas, into valuable carbon nanotubes—nano-sized cylindrical structures with exceptional physical properties.
Carbon nanotubes are renowned for their extraordinary tensile strength, electrical conductivity, and lightweight nature, making them highly sought after in various high-technology fields including electronics, automotive manufacturing, and aerospace engineering. The ability to synthesize these materials economically and sustainably has long been a challenge for materials scientists and engineers. SkyNano’s approach tackles this issue head-on by utilizing carbon dioxide as the feedstock, offering a dual benefit of capturing an environmental pollutant while fabricating advanced materials for batteries. This innovative pathway aligns with the broader push toward decarbonization and circular economy principles in material synthesis.
The project awarded by the Air Force is a collaborative effort that includes SkyNano’s partners, American Energy Technologies Company and Eonix, the latter led by Innovation Crossroads alumnus Don DeRosa. These collaborations are integral to scaling and integrating the novel carbon nanotube production process into existing lithium-ion battery manufacturing workflows. The goal is to establish a reliable domestic supply chain for battery-grade graphite, a crucial anode material that significantly influences battery efficiency, life cycle, and energy density. Having a local source reduces dependence on international suppliers and potential geopolitical risks.
This initiative was mobilized through Innovation Crossroads, a Lab-Embedded Entrepreneurship Program based at Oak Ridge National Laboratory (ORNL). Innovation Crossroads serves as a vital nexus where technology innovators meet entrepreneurial support, world-class technical resources, and industry partnerships. The program nurtures startups like SkyNano and Eonix by embedding them within the research ecosystem of ORNL, providing unparalleled access to materials characterization tools, advanced synthesis methods, and technical mentorship critical for moving breakthrough ideas to commercialization.
Dan Miller from ORNL emphasized the importance of Innovation Crossroads not only in providing access to state-of-the-art facilities but also in fostering a peer network of early-career entrepreneurs specializing in energy and manufacturing sectors. Both SkyNano and Eonix, after being recruited to Knoxville, chose to remain and expand their operations locally—a testament to East Tennessee’s burgeoning innovation infrastructure. Such entrepreneurial retention boosts regional economic development and fortifies the U.S. energy technology pipeline.
The process pioneered by SkyNano involves precision control over the conversion of carbon dioxide into high-purity carbon nanotubes suitable for battery applications, which is a highly complex and multifaceted challenge. The synthesis demands finely tuned reaction conditions to ensure consistent nanotube morphology, electronic properties, and structural integrity. Advances in catalytic materials and reactor designs have been key in driving these improvements, allowing SkyNano to produce materials that meet stringent industry standards required for battery-grade graphite.
Integrating these carbon nanotubes into lithium-ion battery anodes has the potential to substantially enhance battery performance. The nanotubes facilitate improved electrical conductivity and mechanical stability, which translates to higher charge rates, longer battery life, and reduced degradation over time. Moreover, producing battery materials from captured CO2 presents a paradigm shift in material sourcing, potentially lessening the environmental footprint of battery manufacturing.
Douglas, reflecting on the project, highlighted its strategic importance in bolstering U.S. energy security by creating resilient domestic supply chains for critical materials. Furthermore, this endeavor exemplifies the synergistic growth achievable through sustained collaboration between Innovation Crossroads fellows, underscoring the value of combining scientific innovation with entrepreneurial zeal. The project epitomizes the fusion of environmental stewardship with cutting-edge technology development.
The implications of this work extend beyond battery technology alone. Carbon nanotubes have vast applicability across a spectrum of industries due to their unique combination of mechanical strength and electrical properties. Advances in scalable, low-cost synthesis methods such as the CO2-to-carbon nanotube conversion could unlock new frontiers in lightweight structural composites, flexible electronics, and even catalytic systems designed for environmental remediation.
The Air Force’s support signals a broader institutional recognition of the critical role that novel carbon materials play in modern technologies, especially those underpinning the future of energy storage and advanced manufacturing. By bridging the gap between laboratory-scale research and industrial adoption, SkyNano’s initiative represents a vital step in translating fundamental nanoscience into tangible, real-world applications.
Finally, the successful retention and growth of startups like SkyNano and Eonix in the Knoxville region highlight the catalytic influence of Oak Ridge National Laboratory’s Innovation Crossroads program in cultivating a vibrant ecosystem for energy technology innovation. This case study demonstrates the power of embedding entrepreneurial ventures within national laboratories, driving technological advancement while fostering local economic revitalization.
