Renewable energy storage technology

Energy Vault's system is based on the principles of pumped hydro storage, a well-established long-duration energy storage method.

A six-armed crane mechanism that stacks and destacks 35-metric-ton concrete blocks to store and release energy.

A type of rechargeable battery that uses lithium ions as a key component of its electrochemistry. The new polymer can improve their energy storage and output.

Energy Vault's full-scale grid storage plant designed to look like a 35-story crane with six arms, surrounded by thousands of 35-metric-ton concrete bricks. The system stacks and destacks blocks to store and release electrical energy.

A one-seventh scale demonstration unit of the Evie system currently operating in Switzerland for testing and design improvement purposes.

A grid-scale energy storage system using a six-armed crane to stack and destack 35-metric-ton concrete blocks. The standard configuration delivers 4 MW/35 MWh of storage with approximately 9 hours of discharge duration.
