Advanced Carbon Nanotube Flywheel for Pulsed Power Applications Navy SBIR FY2015.2 Sol No.: Navy SBIR FY2015.2 Topic No.: N152-118 Topic Title: Advanced Carbon Nanotube Flywheel for Pulsed Power Applications Proposal No.: N152-118-0348 Firm: Creare LLC 16 Great Hollow Road Hanover, New Hampshire 3755 Contact: Michael Swanwick Phone: (603) 643-3800 Web Site: http://www.creare.com Abstract: The advancement of systems requiring high power (megawatt level) in a short amount of time (seconds to minutes) is increasing, and there is currently no reliable energy storage and release system to complement these technologies on the Navy�s ships. Traditional flywheels are heavy with low tip speeds and often have to be built in place. Creare proposes an advanced carbon nanotube (CNT) flywheel for shipboard pulsed power applications. This flywheel will use state-of-the-art CNT yarns and tapes along with other materials to reduce weight and increase tip speed. During Phase I, we propose to conduct coupon testing of the CNT material, design the advanced flywheel, and conduct initial fabrication and testing of miniaturized high-risk components. In Phase II, Creare proposes to design, fabricate, and test a scaled prototype flywheel demonstrating tip speed in excess of 1000 m/s. Benefits: Advanced lightweight flywheels have many applications in the DoD and larger commercial applications including emerging electric aircraft, grid balancing, and stabilization. We are working with a premier CNT material manufacturer to scale up the delivery of high strength yarns and tapes. High pulse power flywheels can be an enabling technology for alternative energy sources, including solar and wind energy, and for reducing the high load on batteries or pumped-storage hydroelectric.
