Therefore, there is no involvement with the Nuclear Regulatory Commission (NRC) or similar nuclear-specific licensing processes. Instead, their projects are subject to local, state, and national energy regulations, environmental permitting, and grid interconnection approvals. Key regulatory milestones include successful grid interconnection and environmental approvals for projects in China, the U.S., and Australia. For instance, their Rudong, China project received necessary approvals for commercial operation in 2022. Upcoming regulatory focuses involve securing permits for projects under development in Australia and the U.S., with timelines varying by jurisdiction. Energy Vault has not publicly disclosed specific delays or challenges in regulatory processes as of the latest updates. The estimated timeline for new commercial deployments is ongoing, with several projects expected to come online between 2025 and 2027, based on announcements.

Initially, the company secured over $110 million in Series B funding in 2019, led by SoftBank Vision Fund, with additional investments from CEMEX Ventures and others. Post-SPAC merger in 2022, the company raised approximately $235 million in gross proceeds to fuel expansion. As a public company (NYSE: NRGV), Energy Vault’s market cap fluctuates but was approximately $250 million as of mid-December 2025, based on recent stock data. Stock performance in 2025 has shown volatility, reflecting broader market trends in clean energy. Recent Q3 2025 financial results indicate revenue growth driven by expanded markets in Australia and new strategies like "Asset Vault." Specific revenue figures for 2025 show the company is no longer pre-revenue, with contracts contributing to increasing income, though it has not yet reached consistent profitability. Key institutional investors include SoftBank, Prime Movers Lab, and Saudi Aramco Energy Ventures.

[Energy Vault Newsroom](https://www.energyvault.com/newsroom) ### New Hampshire Relevance Energy Vault’s technology could have potential relevance for [[New Hampshire]], particularly in supporting grid reliability and renewable integration within the ISO-NE (Independent System Operator New England) grid, which serves the state. Proximity to existing infrastructure like [[Seabrook Station]] (a nuclear power plant) is less relevant since Energy Vault focuses on storage rather than generation. However, their systems could complement Seabrook’s baseload power by storing excess energy during low-demand periods and dispatching during peaks. The technology readiness level is high, with operational projects globally, making it feasible for near-term deployment in NH if regulatory and commercial agreements are pursued. Alignment with NH legislative initiatives like HB 710, which promotes clean energy, could be strong, as Energy Vault’s solutions support renewable energy goals. Potential applications include grid power stabilization for ISO-NE, powering data centers (a growing sector in the Northeast), and supporting industrial loads with long-duration storage. There is no specific evidence of Energy Vault expressing interest in NH or the Northeast US, but their focus on U.S. markets (e.g., battery projects in Texas and California) suggests scalability to regions like NH if demand arises. Posts on X also indicate a surge in U.S. energy storage capacity in 2025, creating a favorable environment for such deployments. ### Competitive Position Energy Vault competes in the energy storage market with companies like Tesla Energy (Megapack), Fluence, and [[Form Energy]]. Compared to Tesla’s lithium-ion Megapack, Energy Vault’s gravity-based EVx™ offers a longer lifespan and no reliance on scarce battery materials, though it may lack the rapid response times of batteries for short-duration needs. Fluence, another BESS provider, has a broader global footprint and established utility partnerships, posing a challenge to Energy Vault’s market share in battery storage. Form Energy’s iron-air battery technology targets ultra-long-duration storage (100+ hours), potentially outpacing Energy Vault’s current duration offerings, though it remains in earlier development stages. Energy Vault’s unique advantage lies in its hybrid approach (gravity + battery) and low-cost, sustainable storage, but risks include slower adoption of gravity systems compared to proven battery technologies. ### Closing Note Energy Vault is at a growth stage, leveraging operational projects and strategic partnerships to expand its innovative energy storage solutions, with a promising outlook for scaling in renewable-heavy markets. *Report generated December 24, 2025*
