What is the difference between a flywheel and a battery storage system?
Flywheel Systems are more suited for applications that require rapid energy bursts, such as power grid stabilization, frequency regulation, and backup power for critical infrastructure. Battery Storage is typically a better choice for long-term energy storage, such as for renewable energy systems (solar or wind) or home energy storage.
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.
What is a flywheel energy storage system?
Flywheel energy storage systems offer a durable, efficient, and environmentally friendly alternative to batteries, particularly in applications that require rapid response times and short-duration storage. For displacing solar power from midday to late afternoon and evening, flywheels provide a promising solution.
How to connect flywheel energy storage system (fess) to an AC grid?
To connect the Flywheel Energy Storage System (FESS) to an AC grid, another bi-directional converter is necessary. This converter can be single-stage (AC-DC) or double-stage (AC-DC-AC). The power electronic interface has a high power capability, high switching frequency, and high efficiency.
Why should you use a flywheel for solar power?
Moreover, flywheels can store and release energy with minimal losses, particularly when used for short-duration storage (on the order of minutes to a few hours). This makes them ideal for solar power applications where energy needs to be stored during the day and discharged in the evening.
How does a flywheel work?
Here’s a breakdown of the process: Energy Absorption: When there’s surplus electricity, such as when the grid is overproducing energy, the system uses that excess power to accelerate the flywheel. This energy is stored as kinetic energy, much like how the figure skater speeds up their spin by pulling in their arms.
