LEBANON, N.H.--(BUSINESS WIRE)--SustainX, Inc., the developer of an industry-leading energy storage technology using compressed air, today announced that the company is expanding to a new headquarters site.
SustainX will relocate on August 1st from its Lebanon, New Hampshire facility to a larger 42,000 square foot building on Stard Road in Seabrook, New Hampshire. The move comes as the company, recently named one of New Hampshire’s “green launch pad” firms, plans to enter into production of its isothermal CAES technology.
“With the SustainX technology we are now changing the rules for energy storage, providing smarter storage so clean wind and solar power can realize their potential. This site move will give us more space to expand and meet demand,” said Thomas Zarrella, President and CEO of the company. “The move is part of our continued growth as a utility-scale energy storage company and we see our patented isothermal compressed-air technology being a key part of the future of energy storage,” he added.
SustainX is working in the emerging market for utility grid-scale energy storage being created by the growth in renewable generation, and aims to be an alternative to costly "peaker" plants that burn natural gas or other polluting fuels.
The company's energy storage technology, named ICAES™ (for Isothermal Compressed-Air Energy Storage), uses no fuel. SustainX has patented, proprietary thermodynamic and hydraulic control innovations, a design centered on mature industrial components, and use of ambient-temperature, nontoxic working fluids.
Earlier this month, SustainX received an additional U.S. patent giving it control over a technology combining cogeneration with isothermal compressed-air energy storage to turn waste into electricity. Another new patent establishes the company’s ownership of a control system for maintaining constant power to and from its energy storage system.
SustainX was founded in 2007 by engineers from the Thayer School of Engineering at Dartmouth College. It has received funding from the National Science Foundation Small Business Innovation Research Program and the Energy Storage Program at the US Department of Energy, as well as equity investments from top-tier investors Polaris Venture Partners, Rockport Capital, Cadent Energy Partners, General Catalyst Partners, and GE Energy Financial Services.
SustainX has received six US patents to date on core aspects of its technology, solidifying its leading position in the field of compressed-air energy storage. The patents cover a wide range of isothermal systems, including both existing SustainX systems and those in development. The three-year-old company is on track to demonstrate its first one-megawatt, grid-connected system in collaboration with AES Energy Storage, LLC under an award from the Energy Storage Program at the US Department of Energy.
