A combination of technologies — from various forms of batteries to other energy storage methods — will likely be necessary to increase capacity. As shown in this render, energy storage company Energy Vault, along with Skidmore, Owens & Merrill, the architecture and engineering firm behind some of the world's tallest buildings, is integrating gravity energy storage technology into building designs. A view of the world's tallest building, the Burj Khalifa, in Dubai, in December 2022. Two energy storage experts contacted by CNN questioned if the economics of a skyscraper battery could work, given the space that would need to be used for energy storage and the structural changes that would be needed to support the extra weight. Energy Vault has already completed a project in China which it says is the world’s first commercial-scale, non-pumped hydro gravitational energy storage system.
