Skidmore, Owings & Merrill (SOM), in partnership with Energy Vault Holdings, plans to build 1 km-long buildings for gravity-based energy generators and batteries.
The proposal includes two particularly important ideas. The first uses leftover energy from renewable sources such as solar energy or a standard power grid to lift a weight to the top of the skyscraper. When electricity is needed, the weight is released to start a generator and generate electricity.
In addition to the EVu gravity system, the team is proposing a system called EVc. EVc operates on a similar principle to the EVu system, but instead of using large concrete blocks, it utilizes water. Water is pumped to the top of the skyscraper and stored in a reservoir. When electricity is needed, the water is released downward, powering turbines to generate electricity. This technology is already in use in pumped storage hydropower plants today.
“This partnership with Energy Vault is a commitment not only to accelerate the world’s transition away from fossil fuels but also to explore, together, how the architecture of renewable energy can enhance our shared natural landscapes and urban environments. Given the transformative nature of Energy Vault’s technology, we’re especially excited to launch this unique, global partnership,” said SOM Partners Adam Semel.
There are practical difficulties in implementing both ideas due to construction costs, insufficient space, and maintenance issues. However, with the expertise of the company behind the idea, it may be possible to implement it.
