In their study, published in the journal Energy, the researchers propose a new storage solution
The authors called the idea of Lift Energy StorageTechnology (LIFT). According to her, energy is accumulated due to the fact that the elevator lifts high-density materials. This is an interesting option as the elevators are already installed in high rise buildings which means there is no need for additional investment.
There are more than 18 million elevators in operation worldwide, andmany of them do nothing for a considerable amount of time. The idea is that when elevators are not being used to transport people, they can be used to store or generate electricity.
There are still a few details that need to be finalized before deploying the system.In particular, you need to find a place to store the loads on which the system rests at the top of the building when it is fully charged, and at the bottom of the building when it is discharged.
