This Startup Uses Heavy Concrete Blocks to Store Clean Energy

Takeaways:

• Energy Vault has created clean energy storage comprised of 35 tons of heavy solid blocks and a tall tower.
• When there is a surplus of power, a mechanical crane is used to lift the blocks 35 stories in the air.
• The blocks will stay suspended until the power is needed again, where they will be lowered by cables that spin turbines and produce electricity.
