Flywheel energy storage business plan

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.

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.

Are flywheel energy storage systems a viable alternative to batteries?

This mismatch between supply and demand necessitates effective energy storage solutions. While batteries have been the traditional method, flywheel energy storage systems (FESS) are emerging as an innovative and potentially superior alternative, particularly in applications like time-shifting solar power.

What services do flywheels provide to the grid?

In addition to time-shifting energy, flywheels can provide ancillary services to the grid, such as frequency regulation, voltage support, and inertia. These services are essential for maintaining grid stability, particularly as more intermittent renewable energy sources like solar and wind are integrated.

Why should you use a flywheel?

Flywheels can quickly absorb excess solar energy during the day and rapidly discharge it as demand increases. Their fast response time ensures energy can be dispatched as needed, preventing grid instability. Flywheels excel in short-duration storage applications, typically less than four hours.

Do flywheels need more space than battery systems?

Flywheels require more space than some battery systems, particularly if significant energy storage is needed. Their mechanical nature also requires careful siting to minimize risks related to rotational inertia and vibrations. However, advancements in compact flywheel designs are continually addressing these challenges.
