Amber Kinetics was founded to accelerate the world to a safer, more cost-effective, and environmentally sustainable solution for storing energy.
KINETIC ENERGY STORAGE SYSTEM
At the heart of our Kinetic Energy Storage System is a flywheel which converts and stores electrical energy in a rotating mass. Flywheels offer several advantages over batteries: unlimited daily cycling capability, high round-trip efficiency, zero capacity degradation and no chemical reactions. However until now, flywheels have faced two unique challenges – high cost and short duration.
Amber Kinetics co-founder Dr. Seth Sanders first solved the fundamental cost challenge by optimizing the flywheel rotor’s geometry and metallurgical properties, evolving and refining the low-carbon steel alloy’s chemistry and processing steps. The result is a low-cost, high-strength rotor, which is capable of achieving higher performance than with traditional steels.
Amber’s core technology breakthrough is a low-cost, highly scalable rotor of functionally optimized material and construction. In addition to its remarkable resilience to multiple 10,000s of deep cycles, the fundamental material cost is in the range of $50/kwh.
Extending the discharge duration from minutes to hours was the second challenge. It was solved by co-founder Dr. Seth Sanders’ team by innovating in the electromagnetics and power conversion steps involved in accelerating and decelerating the flywheel, enabling nearly zero-loss operation of the storage system in standby mode. Whereas previous generations of flywheels were limited to between 1-15 minutes of duration, Amber Kinetics’ breakthrough in electromagnetics enables the company to offer customers 4 hours of discharge duration, and can be extended even longer if needed.
