What is a flywheel/kinetic energy storage system (fess)?
Thanks to the unique advantages such as long life cycles, high power density, minimal environmental impact, and high power quality such as fast response and voltage stability, the flywheel/kinetic energy storage system (FESS) is gaining attention recently.
What are the advantages of a flywheel versus a conventional energy storage system?
When the flywheel is weighed up against conventional energy storage systems, it has many advantages, which include high power, availability of output directly in mechanical form, fewer environmental problems, and higher efficiency.
Do flywheel energy storage systems need maintenance?
Unlike other storage systems, there is no issue in terms of wear in flywheels; hence, regular maintenance is usually not required. FESS is also developed in the absence of any chemicals. This implies that decommissioning requirements are not needed in flywheel energy storage systems, unlike chemical batteries .
How can flywheels be more competitive to batteries?
The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage.
