With the wave of renewable energy sources linking up to the grid comes an increasing focus on energy storage solutions that will be able to cope with this additional clean power supply.

Energy Vault have merged their Tetris skills with waste materials to offer a solution for long-term energy storage: a system where 35-tonne bricks move up and down a modified construction crane to turn kinetic energy into electricity when needed.

Find out more about this process and their upcoming presentation at the AES Conference this week, here.
