How to convert high-rise buildings into gravity batteries.
The world is undergoing a rapid energy transformation dominated by the growing capacity of renewable energy sources such as wind and solar energy. With the rapid reduction in the cost of renewable energy generation, there is a growing need for energy storage technologies to ensure that electricity supply and demand are properly balanced.
gravity batteries
IIASA researchers have come up with a new energy storage concept that could convert high-rise buildings into gravity batteries to improve power quality in urban environments. Called Lift Energy Storage Technology (LEST), the novel gravity-based energy storage solution uses elevators and empty apartments in tall buildings to store energy.
It stores energy by lifting containers of wet sand or other high-density materials, transported remotely in and out of the elevator with autonomous towing devices. The system would also make use of e C Level Executive List mpty spaces at the top and bottom of the building.
LEST is an interesting option because elevators are already installed in high-rise buildings. This means there is no need for additional investment or space occupation, but rather using what already exists in a different way to create additional value for the power grid and the building owner. Power capability is already installed in elevators with regenerative braking systems that can harvest energy as the elevator descends, so they can effectively be considered pre-installed power generators.
An existing elevator can be used to transport the containers from the lower apartments to the upper apartments to store energy and from the upper apartments to the lower apartments to generate electricity. The idea is that when elevators are not used to transport people, they can be used to store or generate electricity.
There are still some details that need to be refined before the gravity battery system can be implemented. This includes finding space to store the weights on which the system is based at the top of the building when the system is fully loaded and at the bottom of the building when the system is unloaded. Another consideration is the roof load capacity of the existing buildings where the system is installed.
“Flexible, environmentally friendly storage technologies like LEST are set to become increasingly valuable to society in a future where a large portion of its electricity comes from renewable energy,” concludes study co-author Behnam Zakeri. , IIASA Integrated Assessment researcher. and Climate Change Research Group.
“Therefore, policymakers and power system regulators must adopt strategies to incentivize end users, in this case high-rise buildings, to share their distributed storage resources, such as LEST, with the core grid. The coordinated utilization of such distributed resources alleviates the need to invest in large-scale central storage systems.
