Company Overview

Energy Vault develops sustainable, grid-scale energy storage solutions designed to advance the transition to a carbon free, resilient power grid. Energy Vault’s mission is to accelerate the decarbonization of our economy through the development of sustainable and economical energy storage technologies. To achieve this, Energy Vault is developing a proprietary gravity-based energy storage technology. Energy Vault is also designing proprietary energy management software based on artificial intelligence (AI), advanced optimization algorithms designed to control and optimize entire energy systems and a flexible energy storage integration platform suitable for storage technologies of many durations. Energy Vault’s product platform aims to help utilities, independent power producers, and large energy users significantly reduce their levelized cost of energy while maintaining power reliability.

Energy Vault’s gravity-based solutions are based on the well-understood physics and mechanical engineering fundamentals of pumped hydroelectric energy storage, but replace water with custom-made composite blocks, or “mobile masses”, that can be made from low-cost and locally sourced materials, including local soil, mine tailings, coal combustion residuals (coal ash), and end-of-life decommissioned wind turbine blades.

Additionally, the Energy Vault systems are intended to minimize environmental and supply chain risks. The systems are automated with advanced computer control and machine vision software that orchestrate the charging and discharging cycles while meeting a broad set of storage durations starting from 2 hours and continuing to 12 hours, or more.

Following investment and energy storage collaboration announcements in 2021 from industry leaders Saudi Aramco Energy Ventures and Enel Green Power, including joint development for the remediation and beneficial reuse of waste wind blade fiberglass with Enel, Energy Vault continued its global commercial progress and market strategy with:

• Strategic Partnership with Atlas Renewable, a License and Royalty agreement for renewable energy storage with Atlas Renewable LLC (“Atlas Renewable”) and their majority investor China Tianying Inc. (CNTY) (CN: 000035), an international environmental management and waste remediation corporation engaged in smart urban environmental services, resource recycling and recovery, and zero-carbon clean energy technologies. Atlas Renewable made a $50 million investment, which upsized the private placement investment (“PIPE”) from $150 million to $200 million, and has agreed to pay an additional $50 million as a licensing fee payable in 2022 for use and deployment of Energy Vault’s gravity energy storage technology in Mainland China, Hong Kong and Macau.

• Strategic alliance for renewable energy storage with Korea Zinc Co., Ltd., a global leader in non-ferrous metal smelting production including leading positions in Zinc, Lead, Silver and rare metal Indium. The partnership supports Korea Zinc’s strategy to decarbonize their refining and smelting operations focused initially under wholly owned subsidiary Sun Metals Corporation Pty. Ltd. The companies expect to begin project deployment in mid-2022. In addition to the strategic partnership, Korea Zinc made a $50 million investment in the PIPE, which upsized the $100 million PIPE that was announced in connection with the signing of the business combination agreement.

• Joint collaboration with BHP, a leading natural resources company, that will focus on the deployment and implementation of Energy Vault’s energy storage solutions in BHP’s key operations and other potential applications for the technology. The parties have signed a Memorandum of Understanding focused on studying the application of Energy Vault’s technology to support power supply and energy storage at certain BHP operations while exploring opportunities for new applications relevant to BHP’s business.

• Energy storage system agreement with DG Fuels LLC, an emerging leader in renewable hydrogen and biogenic based, synthetic sustainable aviation fuel and diesel fuel. Under the terms of the agreement, Energy Vault agreed to provide 1.6 gigawatt hours (GWh) of energy storage to support DG Fuels across multiple projects, with the first project slated for 500 megawatt hours (MWh) in Louisiana. Energy Vault expects this agreement to provide the opportunity for up to $520 million in revenue across the three projects, the first of which is expected to commence in mid-2022.
