[RenewableEnergyAccess.com] Beacon Power Corporation announced that it has delivered a flywheel-based power system to Bechtel Bettis, Inc., under a contract that it announced in March 2005. The demonstration system, built using a Smart Energy 6 flywheel, is designed to provide a high cycle-life, reliable source of stored energy for a number of potential applications. Beacon Power also announced that it will present a paper, co-authored with personnel from the Naval Surface Warfare Center, entitled “Flywheel Energy Storage for Electric Start and an All-Electric Ship,” at the IEEE Electric Ship Technologies Symposium in Philadelphia on July 27, 2005. The U.S. Navy’s Electric Ship program is focused on development of next-generation vessels that make use of an integrated power system able to support more demanding electrical loads as well as reduce crew size and free up shipboard space. Beacon believes that there may be interest in its flywheel products for such applications because of certain inherent advantages over batteries, including long life, the ability to charge and discharge many thousands of times, the absence of hazardous materials and reduced maintenance requirements. Beacon also manufacturers solar photovoltaic (PV) inverters.
