Flywheels have largely fallen off the energy storage news radar in recent years, their latter-day mechanical underpinnings eclipsed by the steady march of new and exotic battery chemistries for both mobile and stationary storage in the modern grid of the 21st century grid.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.
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.
Could flywheels be the future of energy storage?Flywheels, one of the earliest forms of energy storage, could play a significant role in the transformation of the electrical power system into one that is fully sustainable yet low cost.
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.
