The Natural Energy Laboratory of Hawaii Authority (NELHA), Hawaii Electric Light Co., Ulupono Initiative, and UniEnergy Technologies (UET) are working together to install a 100kW/500kWh advanced vanadium flow battery this year at the Hawaii Ocean Science and Technology Park (HOST Park) administered by NELHA.
UET will supply its ReFlex energy storage system (ESS) for the project, which will begin operations at the NELHA Gateway Center early next year.
The flow battery technology and was developed by the U.S. Department of Energy’s (DOE) Pacific Northwest National Laboratory (PNNL) and commercialized by UET.
“Long duration flow batteries are particularly suitable for island systems to serve as a buffer between the load, variable renewable generation, and expensive fossil fuel generation, allowing for more effective asset utilization,” Dr. Imre Gyuk, director of the DOE energy storage program, said in a June 21 statement.
According to NELHA, Sandia National Laboratories will provide technical consulting and conduct research to analyze how a flow battery performs in an island climate and on an island grid.
“The more installations we have of various energy storage technologies, the more we learn and disseminate,” Dan Borneo, Sandia National Laboratories’ ESS demonstration program lead, said. “This will help the energy storage industry proliferate.”
The U.S. Environmental Protection Agency (EPA) in early June recognized UET with a Green Chemistry Challenge Award for its work in partnership with PNNL on flow battery technology.
