Energy Vault

What Energy Vault does

Energy Vault Holdings, Inc. (NYSE: NRGV) is a publicly traded grid-scale energy storage company that develops and deploys three proprietary technology families: gravity-based systems (G-VAULT and the modular EVx platform) using composite blocks lifted and lowered to store and discharge electricity with 80%+ round-trip efficiency and a 35-year asset life; lithium-ion battery systems (B-VAULT, B-Nest) with multi-story enclosures delivering up to 8x the energy density of conventional BESS; and hybrid hydrogen systems (H-VAULT) combining batteries with fuel cells for multi-day resilience. All assets are orchestrated through a proprietary software stack composed of VaultOS (energy management), Vault-Bidder (AI-driven market bidding and dispatch optimization), and Vault-Manager (battery asset performance analytics).

The company's commercial model has shifted from lower-margin engineering, procurement, and construction (20-25% gross margins) toward an Asset Vault build-own-operate independent power producer model (60-80% gross margins), which now represents roughly 80% of its $1.3+ billion contract backlog. Revenue streams span hardware sales (B-VAULT, B-Nest, Peak Energy sodium-ion supply), long-term service and performance agreements, and software licensing across utility, independent power producer, large industrial, and AI/data center customer segments. Customers and partners include PG&E, NV Energy, ACEN Australia, Jupiter Power, Wellhead Electric, Eskom, Bridge Energy, AusEnergy Services, the EU Green Energy Balkans consortium, Crusoe, Peak Energy, Arevon Energy, Banpu Power, and Belltown Power, with operational presence in the United States, Switzerland, Japan, Australia, South Africa, China, and Europe.

Energy Vault became public in February 2022 through a SPAC merger with Novus Capital Corporation II and is headquartered in Westlake Village, California, with an R&D center in Castione, Switzerland. The company generated $200-205 million in full-year 2025 revenue (up approximately 340% year-over-year from $46.2 million in 2024), reported its first positive adjusted EBITDA in Q4 2025, and finished the year with $103.4 million in cash and a global owned asset base exceeding 1 GW following the closing of an 850 MW BESS portfolio acquisition from BayWa r.e. AG in Japan and the McMurtre 175 MW/350 MWh project in ERCOT North.

Direct peers

• Fluence Energy: Fluence is the most directly comparable peer — a pure-play grid-scale BESS integrator with a similar mix of utility and IPP customers, project-level and asset-ownership revenue streams, and AI-driven software (Mosaic) for fleet dispatch; both compete head-to-head on BESS project bids and are pivoting toward own-and-operate models.
• ESS Inc. ESS builds iron-flow battery systems for long-duration storage (6-12+ hours), a direct alternative to Energy Vault's G-VAULT and H-VAULT for LDES applications; both target utility-scale decarbonization and are pre-IPO/SPAC-era companies commercializing first-generation long-duration technology.
• Form Energy: Form Energy is a leading iron-air battery LDES developer (100+ hour duration) addressing the same multi-day storage market as Energy Vault's H-VAULT hydrogen system; both are Boston/Pennsylvania or US-based hardware developers with strong backing and are viewed as direct LDES alternatives.
• Stem Inc. Stem Inc. combines AI-driven energy storage software (Athena) with customer-sited and utility-scale storage assets, directly paralleling Energy Vault's Vault-Bidder AI dispatch and IPP/Asset Vault model; both pivot toward software-plus-asset-owner business models in CAISO/ERCOT.
• Eos Energy Enterprises: Eos manufactures zinc-based battery storage for utility-scale long-duration applications, sharing Energy Vault's positioning as a U.S.-listed LDES challenger; both target 4-12 hour storage with alternative chemistries to Li-ion and serve similar regulated and IPP customer segments.

Broad incumbents

• Tesla Energy (Megapack): Tesla Megapack is the dominant incumbent in utility-scale Li-ion BESS, with massive Lathrop factory capacity, vertically integrated cell supply, and significant ERCOT/Australia presence — overlapping directly with Energy Vault's B-VAULT/B-Nest targets but operating as part of a much larger EV/energy ecosystem.
• BYD Energy Storage: BYD supplies integrated BESS hardware (e.g., the Cube Pro 543 MWh deployed by Energy Vault for NV Energy) and competes directly on price and capacity in utility-scale storage markets globally; a vertically integrated Chinese manufacturer with massive scale.
• Saft (TotalEnergies): Saft, a TotalEnergies subsidiary, supplies industrial battery storage systems (including Li-ion and nickel-based) to utilities and large industrial customers, overlapping with Energy Vault's B-VAULT long-duration products across geographies and regulated-utility customer segments.

Emerging players

• KORE Power: KORE Power is a U.S.-based battery cell and BESS system manufacturer targeting utility-scale and IRA Domestic Content-eligible projects, overlapping with Energy Vault's B-Nest strategy and U.S.-manufactured sodium-ion positioning for AI/data-center customers.
• Highview Power: Highview Power develops cryogenic / liquid-air long-duration energy storage (CRYOBattery), an alternative LDES technology to Energy Vault's gravity and hydrogen offerings; both target multi-day storage with no geographical constraints and pursue utility-scale project pipelines.
