Developments and News

On June 5, 2025, Energy Vault signed an agreement with Jupiter Power to supply a 100 MW/200 MWh battery energy storage system (BESS) in the Electric Reliability Council of Texas (ERCOT) region. This project will utilize the company’s X-Vault integration platform, UL9540-certified B-VAULT hardware, and VaultOS Energy Management System, with commercial operations expected to commence by August 31, 2025. This agreement follows the completion of a similar 100 MW/200 MWh installation in July 2024.

A LinkedIn update dated March 12, 2025, announced the securing of $18 million in project financing for the 57 MW/114 MWh Cross Trails BESS in the ERCOT market. This system, backed by a ten-year offtake agreement with Gridmatic, is projected to deliver a 15% internal rate of return, with over $12 million in investment tax credit funds anticipated in the third quarter of 2025.

Since its NYSE listing in February 2022 via a merger with Novus Capital Corporation II, Energy Vault has reportedly deployed 1.4 GWh of storage capacity globally and secured investments from SoftBank Vision Fund, Saudi Aramco Energy, and China Tianying Inc.

Financial and Strategic Aspects

On May 30, 2025, the company filed a prospectus supplement under Rule 424(b)(5) confirming an Equity Purchase Agreement with Hudson Global Ventures.

The last recorded sale price on May 29, 2025, was $0.93 per share.

Energy Vault’s strategy combines various storage technologies to address short-, long-, and ultra-long-duration applications. VaultOS software manages dispatch across gravity blocks, batteries, and hydrogen assets. As of June 2025, the B-VAULT project portfolio reportedly exceeds 2 GWh of operational and in-development capacity, supported by 2.4 GWh of committed supply-chain equipment.

Market Position and Industry Context

Federal incentives and state renewable mandates have accelerated grid-scale storage deployment in the U.S. Within this expanding market, Energy Vault differentiates itself through gravity-based storage, which is designed to offer extended discharge durations with potentially reduced degradation compared to chemical batteries. Collaborations with utilities, independent power producers, and global partners—together with recognition from the SoftBank Vision Fund and the World Economic Forum—illustrate the company’s position within a sector focused on cost-effective, long-duration storage solutions.
