Enabling a Renewable World™

Clean & Affordable Energy

Energy Vault set out to solve one of the largest global problems facing the planet today, how to store renewable energy in both an economical and sustainable way to end the world’s reliance on fossil fuels. Energy Vault is accelerating the global clean energy transition and enabling a fully renewable world. One of the ways we do this is by utilizing a circular approach that repurposes local waste materials, often otherwise destined for landfill, to build our products. Our goal is to support the environmental transformation of our energy sector worldwide via waste remediation for beneficial reuse and to advance the global transition to a clean energy future through energy storage innovation.

Sustainable Industrialization

Industry Innovation

Energy Vault enhances established technologies with proprietary design, advanced computer control, and machine vision to create an energy storage economic breakthrough.

Key to the Energy Vault system design is building on established practices within existing trillion-dollar industries to accelerate scalability and time to market while introducing new innovations across material science, structural design, and proprietary motion control software.

Responsible Production

Locally Sourced Materials & Labor

Energy Vault’s commitment to sustainability is reflected in our circular approach to production design which includes the use of locally sourced materials and repurposing of recycled waste, diverted from landfills.

Energy Vault’s sustainable production design ensures that the systems are built to meet international building and environmental protections standards. Locally sourced materials, supply chain, and work force support sustainable construction design and create economic value within the local community.


Coal Ash Remediation

Energy Vault supports the global transition away from fossil fuels through an innovative solution to repurpose coal ash for beneficial reuse in energy storage.

Energy Vault is the only energy storage technology that repurposes on-site coal combustion residuals in mobile mass manufacturing, creating an economically attractive alternative to expensive disposal fees and supporting a valuable circular economy.

Circular Renewable Energy Economy

Wind Blade Recycling

Energy Vault provides a unique opportunity to create a circular renewable energy economy with wind power production to improve dispatchability and support the re-powering process.

Decommissioned blades from a repowered wind farm can be mechanically processed onsite and the composite glass fiber material is added to soil mix to produce and enhance properties of gravity storage composite bricks.

International Implementation

Global Partnerships

Energy Vault’s collaborative partners are vital to achieving our goal to transform the world’s approach to affordable, reliable, and sustainable electricity.

Energy Vault partnership programs are designed to enhance sustainable production design and to encourage global deployment of Energy Vault solutions.
