This paper estimates the cost of installed capacity energy storage cost of LEST to be 62 USD/kWh, assuming an average height difference between the upper and lower reservoirs of 100 m. The cost of LEST with an average height difference of 300 m is 21 USD/kWh, whereas an average height difference of 50 m costs 128 USD/kWh.
It highlights the importance of considering multiple factors, including technical performance, economic viability, scalability, and system integration, in selecting ESTs. The need for continued research and development, policy support, and collaboration between energy stakeholders is emphasized to drive further advancements in energy storage.
It relies on the use of elevators in buildings to lift solid masses in charging mode. It lowers the same mass to produce electricity in discharge mode. “Energy is stored as potential energy by elevating storage containers with an existing lift in the building from the lower storage site to the upper storage site,” the scientists said.
New materials and compounds are being explored for sodium ion, potassium ion, and magnesium ion batteries, to increase energy storage capabilities. Additional development methods, such as additive manufacturing and nanotechnology, are expected to reduce costs and accelerate market penetration of energy storage devices.
