ENERGY STORAGE SYSTEM PRICES IN SWAZILAND COSTS
Technological advancements are dramatically improving solar storage container performance while reducing costs. Next-generation thermal management systems maintain optimal
The installed capacity energy storage cost of LEST is 21–128 USD/kWh. LEST is a decentralized solution for energy storage with daily to weekly cycles, based on the operation of lifts in high-rise buildings.
The higher the height difference between the lower and upper storage sites, the lower the cost of a Lift Energy Storage Technology (LEST) project. LEST systems are particularly interesting in buildings with rope-free elevators, and they can also provide tuned mass damper services on the top of very high buildings.
Conclusion Lift Energy Storage Technology (LEST) could be a viable alternative to long-term energy storage in high-rise buildings. LEST could be designed to store energy for long-term time scales (a week) to generate a small but constant amount of energy for a long time.
LEST is particularly interesting in China ghost towns. There are several ghost towns where the lifts could be used as energy storage devices. A review of ghost cities in China can be seen in Ref. . Fig. 9 b is a world map with the number of buildings higher than 250 m in a city.
