What They Do

Energy Vault specializes in innovative energy storage solutions aimed at addressing the intermittency challenges of renewable energy. The company operates across three primary technology domains: gravity-based energy storage, battery systems, and hydrogen technology. Energy Vault is recognized for its technology-agnostic approach, which allows it to provide tailored solutions to customers rather than promoting a single storage technology (source: energyvault.com). The flagship G-VAULT family of products utilizes a unique gravity storage mechanism that maintains high efficiency and offers adjustable energy-to-power ratios, making it suitable for various applications (source: energyvault.com). Additionally, the company has developed a comprehensive software ecosystem that enhances operational control and optimizes energy dispatch across diverse storage and generation assets.

Projects & Track Record

Energy Vault has made significant strides in project execution, having deployed 1.4 GWh of energy storage solutions since 2023 (source: energyvault.com). Notable projects include a large-scale battery installation in Stanton, Orange County, which integrates 68.8 megawatts/275.2 megawatt-hours for W Power and Wellhead Electric, marking it as one of the largest in Southern California (source: energyvault.com). Furthermore, Energy Vault has secured a transformative 400 megawatt-hour project with ACEN Renewables at their New England solar farm in New South Wales, Australia, which is touted as the largest in the country (source: energyvault.com). This project exemplifies the company's capability to deploy its gravity storage technology at scale.

Recent Developments

In recent months, Energy Vault has announced significant developments, particularly in Australia. In May 2024, the company revealed its first project in Australia, a 400 megawatt-hour initiative with ACEN Renewables, followed by a commitment to a full gigawatt-hour project, indicating a rapid expansion in the region (source: energyvault.com). The partnership with the State Electricity Commission (SEC) to build and operate a 100 MW/200 MWh battery project further validates Energy Vault's innovative technology and positions it as a leader in the energy storage market (source: energyvault.com). These developments not only enhance the company's project portfolio but also reflect growing investor confidence in its capabilities.

Working There

Energy Vault fosters a dynamic work environment that emphasizes innovation and customer-centric solutions. The company operates across various functional areas, including engineering, R&D, software development, and project delivery teams, which are crucial for integrating and deploying customer solutions (source: energyvault.com). With offices in Switzerland and significant operations in Australia, Energy Vault is actively hiring to support its growth ambitions. The culture is characterized by a commitment to sustainability and technical excellence, attracting professionals who are passionate about addressing global energy challenges (source: energyvault.com). The company's recognition as a Technology Pioneer by the World Economic Forum underscores its appeal to purpose-driven individuals focused on making a positive impact.
