Costa Rica Flywheel Energy Storage

What is a flywheel energy storage system?

A flywheel energy storage system is a mechanical device used to store energy through rotational motion. When excess electricity is available, it is used to accelerate a flywheel to a very high speed. The energy is stored as kinetic energy and can be retrieved by slowing down the flywheel, converting the motion back into electricity.

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 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.

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 the advantages of a flywheel system?

Flywheel systems have several advantages, particularly in applications requiring fast charge and discharge cycles. Rapid Charge/Discharge: Flywheels can charge and discharge electricity much faster than traditional batteries, making them ideal for balancing power grids or managing short-term fluctuations in energy demand.

How long do flywheels last?

Long Lifespan: With no chemical reactions involved, flywheels can last for tens of thousands of cycles, significantly outperforming batteries in terms of longevity. High Efficiency: Flywheel systems are highly efficient at storing and releasing energy, with minimal energy loss over time.
