Energy Vault Holdings, Inc. is a utility-scale energy storage company designed to address the intermittency challenges of renewable energy sources like wind and solar. The company's comprehensive product portfolio spans short, long, and ultra-long duration storage needs. Its core offerings include B-Vault (lithium-ion battery energy storage systems), G-Vault (proprietary gravity-based energy storage that captures potential energy by elevating heavy composite blocks), and H-Vault (hybrid and green hydrogen storage). These hardware solutions are integrated and optimized by Vault-OS, the company's proprietary, technology-agnostic energy management system software. Historically, Energy Vault has generated the majority of its revenue—which reached $203.7 million in 2025—through Engineering, Procurement, and Construction (EPC) project deliveries, equipment sales, and intellectual property licensing. Recently, the company has strategically shifted toward an 'Own & Operate' asset management model, known as Asset Vault, to generate predictable, recurring tolling revenues from its own energy storage projects. Geographically, Energy Vault operates globally with dual headquarters in Westlake Village, California, and Lugano, Switzerland, and has deployed major projects in the United States, Australia, and China. The company's competitive position is bolstered by its ability to offer a diversified suite of storage durations and its recent expansion into providing power infrastructure for modular data centers and AI applications.
