Over the years, traditional forms of energy storage have been developed and utilized to store excess energy for future use. However, these methods come with several limitations that hinder their efficiency and sustainability.

One common form of traditional energy storage is chemical batteries. These batteries store electrical energy in chemical form for later use. They are commonly used in electronics and vehicles as they can be recharged multiple times. However, these batteries have limited lifetimes and can only hold a certain amount of charge before needing to be replaced or recharged again.

Another method is pumped hydro-storage, which uses excess electricity to pump water from a lower reservoir to a higher one. When there is a need for electricity, the water is released back into the lower reservoir through turbines that generate electricity. Though this method has been widely used for decades, it requires specific geographical conditions such as an elevated area near a body of water, making it limited in its application.

Thermal storage is another form where excess electricity is converted into heat or cold using equipment such as heat pumps or chillers. The stored heat or cold can then be used at a later time for space heating or cooling purposes. However, thermal storage systems have relatively low efficiencies due to heat losses during the conversion process.

Compressed air energy storage (CAES) involves storing compressed air in underground caverns and releasing it when needed to power turbines that produce electricity. While this method has shown potential for large-scale energy storage, it requires specific geological formations for underground storage facilities.

All these traditional forms suffer from various limitations that affect their efficiency and scalability. They often require specific geographical conditions, have limited lifetimes or capacities, and are not always eco-friendly due to their reliance on non-renewable resources.

These limitations have led to the search for alternative forms of energy storage that are more efficient, scalable, and sustainable. This has resulted in several breakthroughs and innovations in energy storage technology, such as grid-scale batteries, flywheel systems, hydrogen storage, and thermal storage using phase-change materials.
