BESS are currently the most widely deployed energy storage technology. They offer a wide range of capabilities, including fast response times, high energy density, and modularity. Several battery chemistries are available, including:

Optimization Strategies for BESS:

Pumped Hydro Storage (PHS)

PHS is a mature and well-established energy storage technology that uses the potential energy of water stored in an upper reservoir to generate electricity. Water is released from the upper reservoir to a lower reservoir, driving turbines that generate electricity. PHS is a highly scalable and cost-effective solution for large-scale energy storage.

Optimization Strategies for PHS:

Thermal Energy Storage (TES)

TES involves storing energy in the form of heat or cold for later use. TES can be used to store solar thermal energy, waste heat, or electricity. Several TES technologies are available, including:
