This paper argues that LEST could fill the gap for decentralized energy storage technologies with weekly energy storage cycles. See Fig. 8 for LEST with MGES [58], batteries, P. [pdf]
Lift Energy Storage Technology (LEST) is a gravitational-based storage solution. Energy is stored by lifting wet sand containers or other high-density materials, transported remotely in and out of the lift with autonomous trailer devices. The system requires empty spaces on the top and bottom of the building.
Conclusion This paper concludes that Lift Energy Storage Technology 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.
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. . In some cases, the investors do not rent empty apartments because they want to be flexible to sell the flat any time they get a good price. So, LEST can be a good application for such empty flats.
Electrochemical storage (batteries) will be the leading energy storage solution in MENA in the short to medium terms, led by sodium-sulfur (NaS) and lithium-ion (Li-Ion) batteries.
The world is undergoing a rapid energy transformation dominated by growing capacities of renewable energy sources, such as wind and solar power. The intrinsic variable nature of such renewable energy sources calls for affordable energy storage solutions. This paper proposes using lifts and empty apartments in tall buildings to store energy.
The pace of integration of energy storage systems in MENA is driven by three main factors: 1) the technical need associated with the accelerated deployment of renewables, 2) the technological advancements driving ESS cost competitiveness, and 3) the policy support and power markets evolution that incentivizes investments.
