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.
What is a flywheel energy storage system?
Flywheel energy storage systems (FESS) are a great way to store and use energy. They work by spinning a wheel really fast to store energy, and then slowing it down to release that energy when needed. FESS are perfect for keeping the power grid steady, providing backup power and supporting renewable energy sources.
How does a flywheel retain energy?
Energy Storage: The flywheel continues to spin at high speed, maintaining energy as long as friction and resistance are minimized. The longer it spins, the more energy it holds, similar to how the skater retains rotational energy as they keep spinning.
What are some new applications for flywheels?
Other opportunities for flywheels are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage. The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries.
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.
How can flywheels be more competitive to batteries?
To make flywheels more competitive with batteries, the use of new materials and compact designs can increase their specific energy and energy density. Additionally, exploring new applications like energy harvesting, hybrid energy systems, and secondary functionalities can further enhance their competitiveness.
