Title: Sub-Area: 2.5 Demonstration of Promising Energy Storage Technologies - Project Type: Flywheel Energy Storage Demonstration (Revision V1.0)

Technical Report ·
DOI:https://doi.org/10.2172/1240378· OSTI ID:1240378

In this program, Amber Kinetics designed, built, and tested a sub-­scale 5 kWh engineering prototype flywheel system. Applying lessons learned from the engineering prototype, Amber Kinetics then designed, built and tested full-­size, commercial-­scale 25 kWh flywheel systems. The systems underwent basic functional qualification testing before being installed, sequentially, at the company’s outdoor test site in Alameda, CA for full-­speed field-testing. The primary considerations in testing the prototype units were to demonstrate the functionality of the system, verify the frequencies of resonant modes, and quantify spinning losses and motor/generator efficiency.
