Flywheel energy storage, also known as kinetic energy storage, is a form of mechanical energy storage that is a suitable to achieve the smooth operation of machines and to provide high power and energy
Usually HAZOP studies or structured safety assessments, including safety tests, are needed to comply with regulations and to document that a comprehensive engineering risk assessment has been performed. Software and tools exists to guide this process and to demonstrate compliance.
This work considers the requirement of health management for a hybrid flywheel-battery energy storage system. A novel prediction method including the construction of health indicator and RUL prediction is proposed for the flywheel support bearings inside the FESS.

Dive into the research topics of ''A novel machine learning model for safety risk analysis in flywheel-battery hybrid energy storage system''. Together they form a unique fingerprint.
This analysis examined the role of flywheel energy storage systems (FESSs) in the integration of intermittent renewable energy sources into electrical grids and microgrids.
This project explored flywheel energy storage R&D to reach commercial viability for utility scale energy storage. This required advancing the design, manufacturing capability, system cost, storage capacity, efficiency, reliability, safety, and system level operation of flywheel energy storage technology.
One of the advantages of flywheel technology is the environmental tolerance; chemical batteries perform poorly outside of a limited temperature range which often necessitates axillary heating and cooling systems that reduce system power conversion efficiency.
Amber’s proposed flywheel energy storage project is the culmination of several years of flywheel R&D. Energy storage technology that does not show degradation can be applied to solve multiple problems the current aging electric grid faces.
The project played a role in boosting the energy storage capacity by more than 28%, a dramatic impact on the cost effectiveness of the technology. Amber Kinetics flywheels operate in a vacuum to minimize the friction loss from air.
Installing 100 MW’s worth of flywheels used for distribution can reduce demand charges by $36 million and provide $8 million of energy savings a year since the FESS can eliminate mid-day peak and evening peaks of electricity use. Lithium battery technology can only do one peak reduction a day.
The safety design criteria were validated though a series of induced failures and overstress events. The flywheels were completely tolerant of a number of fault scenarios such as a loss of vacuum, loss of power, and overspeed; they survived these types of events without damage and were easily put back into service.
