Energy Storage Systems

Go to Energy Storage Systems


A variety of energy storage systems can be used to help improve power system reliability by balancing utility grids and electricity distribution or smoothing the integration of renewable energy from sun, wind and hydro power. Energy storage systems may include lithium-ion battery banks used with photovoltaic solar arrays, tanks of molten salt that store heat from concentrating solar (CSP), or pumped storage hydropower systems (PSH) used in conjunction with wind and solar photovoltaic farms.

Compressed Air Energy Storage

SwRI develops solutions for novel energy storage systems, including flywheels and compressed air storage. Our work includes a patented apparatus for use in compressed air energy storage.

Pumped Storage Hydropower

This technology entails pumping water from a lower elevation to a higher elevation when there is surplus renewable energy, then releasing water from higher elevations to generate electricity when demand increases.

Thermal Energy Storage

CSP systems convert solar energy into heat that generates steam to power electricity-generating turbines. SwRI’s chemical engineers have developed thermal energy storage applications using novel encapsulation formulation of molten salt capsules.
