Hawaiian Electric Co. and California-based Amber Kinetics have agreed to conduct a joint energy storage pilot project to test the capability of a flywheel system.
Amber Kinetics will build and install an Amber Gen2 Model 25 steel flywheel system, a commercially available four-hour duration flywheel, at Hawaiian Electric’s Campbell Industrial Park generating station on O‘ahu, where the utility will evaluate its operation.
According to the companies, Amber’s steel flywheel is a multi-hour energy storage system capable of charging and discharging electricity for multiple duty cycles per day. A flywheel is a rotating mechanical device that is used to store and release energy. The storage system can provide renewable firming and peak energy shifting, flexible capacity, and ancillary services like voltage smoothing and frequency response for reliable utility operation.
“Hawaiian Electric Co. is a leader among U.S. utilities for adopting and integrating renewable energy to create a sustainable energy future. Now it is continuing that leadership by exploring the potential of flywheel energy storage,” said Ed Chiao, Amber Kinetics’ co-founder and CEO.
“Energy storage is essential to reach a 100 percent renewable energy future, optimizing the use of Hawai‘i’s abundant but variable solar and wind energy,” said Shelee Kimura, Hawaiian Electric vice president for corporate planning and business development. “We are collaborating with a variety of partners to test a range of energy storage technologies, and we are very excited to work with Amber Kinetics to evaluate this very promising flywheel energy storage system.”
The project is jointly funded by Hawaiian Electric and Energy Excelerator. In addition, Energy Excelerator and Hawaiian Electric are collaborating on nearly a dozen clean energy projects, such as Stem Inc.’s 1 MW behind-the-meter energy storage project and Bidgely’s behavior-based demand response tool.
