SEABROOK, N.H., Oct. 18, 2011 /PRNewswire-iReach/ — SustainX, Inc., developer of an industry-leading, transformative technology for utility-scale energy storage using compressed air, today announced that it has received a 7th U.S. patent that provides additional technology options for its isothermal compressed-air system, including variants allowing either hydraulics or a mechanical crankshaft.
The crankshaft design is a mature, simple, reliable technology, has low frictional losses making it very efficient, and can transfer large amounts of power, which supports the construction of SustainX’s, megawatt-scale storage systems.
The new patent award comes at the same time SustainX was named as a “2011 Global Cleantech 100″ company, a list of leading businesses created by the Cleantech Group after a review of more than 4,200 clean technology companies around the world. The Global Cleantech 100 list highlights the promise of private, clean technology companies, focusing on those companies which are most likely to make the most significant market impact over the next five to 10 years. Zip Car and Digital Lumens, both also New England companies, were named on the list last year.
“The patent award is an important milestone for SustainX because it combines the mature, reliable technology of crankshafts with our patented heat-exchange methods and allows us to design energy-storage systems that are more powerful, compact, and efficient than ever,” said Dax Kepshire, Vice President and co-founder of the company. “This patent (No. 12/879,595) expands the types of systems that SustainX can develop, providing more market options.”
