About Us

Energy Vault is the creator of gravity and kinetic energy based, long-duration energy storage solutions that are transforming the world’s approach to delivering reliable and sustainable electricity. Click Here to watch our Drone Video of our Commercial Demonstration Unit.

Energy Vault has created the world’s only cost-effective, utility-scale gravity-based energy storage system that is not dependent on land topography or specific geology underground.

Compared to incumbent stationary energy storage solutions – most notably chemical batteries – Energy Vault provides a sustainable alternative that does not degrade over the life of the project and has competitive performance with round-trip efficiency between 80 to 90% – all at a significantly lower initial CapEx and levelized cost per kilowatt-hour price point.

Panel 1

Why Storage?

At the forefront of technology, intermittent renewable energy sources, such as wind and solar are limited in their capacity to consistently deliver energy to the grid.

Why Now?

Renewable energy is now widely available and affordable. However, production unpredictability and intermittency from reliance on factors such as wind and sunlight mean that renewables have not been able to fully replace fossil fuel generation.

Our Solution

For the first time in history, our transformative energy storage technology enables renewables to deliver around-the-clock baseload power for less than the cost of fossil fuels. Energy Vault’s ready-to-deploy solution combined with low cost solar or wind renewable generation is lower than the most economical existing, fully-amortized fossil fuel-based power plants (i.e. combined cycle natural gas).

Our breakthrough technology was inspired by pumped hydro plants that rely on gravity and the movement of water to generate power.

The Energy Vault solution utilizes the same fundamentals of physics and kinetic energy as pumped hydro but replaces the water with custom made composite blocks utilizing an extremely innovative use of low-cost materials.

These low-cost blocks, combined with our patented system design and some very clever control software, has allowed us to deliver all the benefits of a pumped hydro system but at a much lower price, starting size and without the need for hard to find topography.

Operating Parameters

– 35 ton composite bricks are lifted to create a tower; energy is stored in the elevation gain

– Bricks are then returned to the ground and the kinetic energy generated from the falling brick is turned back into electricity

– Specially engineered control software ensures the bricks are placed in exactly the right location each time

– Modular and flexible with plant capability ranges of 20-35-80 MWh storage capacity and a 4-8MW of continuous power discharge for 8-16 hours

– Ideally suited to long duration storage with very fast response times, The system may also be used to deliver short and medium-term ancillary services
