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.
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.
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.
