SustainX, a clean-tech company that is changing the way that air energy is stored, has relocated from its Lebanon, New Hampshire facility to a larger, 42,000 square foot building on 72 Stard Road in Seabrook, New Hampshire.

SustainX was founded in 2007 by engineers from the Thayer School of Engineering at Dartmouth College. The company currently employs 24 people and plans to continue hiring over the next six months.  Its patented technology stores utility-scale electrical energy in the form of compressed gas air allowing it to be regenerated on demand. 

“This company is another example of New Hampshire producing some of the best advanced design and manufacturing companies in the world,” said Michael Bergeron, Business Development Manager for the NH Division of Economic Development.  Bergeron assisted the company in its statewide search for new space and ERZ tax credits.  “SustainX had also considered moving to Massachusetts but found New Hampshire to be a much better option both short term and long term,” he said.

“The Seabrook building is a perfect fit and location and New Hampshire is a good place to grow our company,” said Dax Kepshire, co-founder and Vice President of SustainX.

Thomas Zarrella, SustainX President, CEO and Director added, “Seabrook also allows us to attract labor from Boston as well as southern New Hampshire.”  Zarrella, the former president of GT Solar, was hired last spring to lead the company as it continues to grow in New Hampshire.

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 U.S. Department of Energy.
