About

Amber Kinetics designs and deploys flywheel energy storage systems (AKESS) for modern grid energy storage needs, providing multiple cycles of kinetic energy without chemical degradation to support the transition from fossil fuels to sustainable renewable generation. The company's flywheel technology offers several key advantages over chemical battery alternatives: full charge and discharge power available at all levels of charge, the ability to be cycled frequently with no impact to performance, significantly longer life, minimal maintenance, and lower levelized cost of energy storage versus other technologies. Amber Kinetics' flywheels provide real and accurate state-of-charge measurement, accurate response time validation, and the ability to charge and discharge without unexpected limitations. The company has demonstrated operational resilience, with flywheel units riding through two earthquakes without operation interruptions. With 16 years of experience, Amber Kinetics has accumulated over 1,642,583 cumulative global flywheel operational runtime hours and discharged over 2.01 GWh to date. The company serves a growing global customer base and deployment portfolio, backed by the industry's most comprehensive protection plans. Amber Kinetics differentiates itself through its pure kinetic energy storage approach eliminating chemical degradation entirely, its proven long-duration operational track record, and its commitment to providing an emission-free, economical, and safe energy storage solution. The company is a member of the American Clean Power Association and subscribes to the United Nations Global Compact on climate action, and has received Frost & Sullivan's 2018 North American Alternative Storage Technology Innovation Award and the 2017 PV Magazine Array Changing Technologies Award. Founded in 2009 and headquartered in Union City, California, Amber Kinetics has raised approximately $25 million in a Series C round backed by OSTI and Elemental.
