SEABROOK, NH–(Marketwire – Sep 5, 2012) – SustainX, Inc., developer of an industry-leading, transformative technology for utility-scale bulk energy storage using compressed air, today announced that it has been issued 11 additional U.S. patents that provide core protection in key areas related to its isothermal compressed air energy storage (ICAES™) technology. The new patents bring SustainX’s overall ICAES-related patent count to 23, all of which have been issued within the last two years.
“We’re focused on bringing our grid-scale energy storage technology to market and a broad intellectual property portfolio is a key part of our strategy,” said Tom Zarrella, SustainX President and CEO. “SustainX now holds more than 450 patent claims broadly applicable across our technology space, which we believe will make it quite difficult for competitors to challenge us.”
SustainX’s isothermal (constant-temperature) energy storage system removes heat from air being compressed for storage and returns heat when that air is expanded to generate electricity. This heat transfer greatly reduces the energy efficiency losses of conventional high-pressure air compression and eliminates the need to burn fossil fuel as part of the expansion process. In addition, the SustainX system uses pipe-type storage, which can be located almost anywhere.
