Gekko; Aramco Ventures$100M$1.1BEnergy Vault develops gravity-based, grid-scale renewable energy storage solutions using composite blocks made from waste materials, inspired by pumped hydro principles, offering a more efficient, durable, and sustainable alternative to traditional batteries. The company launched its EVx platform in April 2021 with support from Saudi Aramco Energy Ventures and completed a commercial-scale deployment in 2020. In August 2021, Energy Vault raised $100 million in Series C funding led by Prime Movers Lab, with participation from existing investors SoftBank Vision Fund, Saudi Aramco Energy Ventures, Helena, and Idealab X, plus new investors including Pickering Energy Partners, SailingStone Global Energy Transition, A.T. Gekko, Crexa Capital Advisors, Green Storage Solutions Venture I, and Gordon Crawford. The funds support execution of growth plans, global deployments, and fulfilling a strong customer pipeline. By October 2021, Energy Vault presented an enterprise value of approximately $1.1 billion in the context of a potential business combination with Novus II (NYSE: NXU), highlighting an attractive valuation compared to energy storage and transition peers. The transaction structure included Novus II's ~$288 million cash in trust, a ~$100 million PIPE, and Energy Vault's $116 million balance sheet cash, expected to fund operations through cash flow positivity in 2024. The company reported a developed pipeline with over 361 customer engagements representing ~$32 billion in potential projects over 5-10 years and 30-40% lower LCOE. Post-Series C, Energy Vault pursued a SPAC merger, with Prime Movers Lab holding significant shares pro forma at December 31, 2021. The funding and subsequent developments positioned Energy Vault to scale its technology for energy providers and industrial customers aiming for sustainability and decarbonization goals amid the global shift to renewables.
Jul-21Undisclosed stageHelena$20M-Energy Vault is a renewable energy storage company that creates grid-scale energy storage systems using gravity-based technology, vertically lifting and descending massive weights to store and release energy. The systems can be manufactured from waste materials, creating environmental remediation benefits while reducing costs and transportation emissions. In July 2021, Helena announced a strategic partnership with Energy Vault and completed a $20 million investment through its for-profit arm, Helena Special Investments. The investment was part of a broader funding effort that included other investors such as Saudi Aramco Energy Ventures, SoftBank Vision Fund, CEMEX Ventures, Idealab, and Neotribe Ventures, with Helena Founder and CEO Henry Elkus joining Energy Vault's board of directors. Shortly after this investment, on August 25, 2021, Energy Vault announced a Series C funding round of $100 million, and on September 9, 2021, the company announced plans to go public via a special-purpose acquisition merger with Novus Capital Corporation II at an initial valuation of $1.6 billion, with an expected $100 million common stock PIPE commitment and up to $388 million in gross cash proceeds.
Aug-19Series BSoftBank Group$110M-Energy Vault is a Swiss startup founded in 2018 that develops gravity-based energy storage technology using massive 35-ton composite bricks stacked into towers by an autonomous crane system. The system stores renewable energy by lifting bricks during surplus generation and generates electricity by lowering them, offering long-duration storage at lower costs than pumped hydro without geographic constraints. It addresses key challenges in integrating intermittent renewables like solar and wind into power grids. On August 14, 2019, Energy Vault closed a $110 million Series B funding round with the entire investment from SoftBank Vision Fund, marking the fund's first foray into energy storage. The capital aims to accelerate global deployment of its utility-scale technology, with the company already securing customer agreements across four continents. SoftBank partner Andreas Hansson joined the board, and executives highlighted the technology's potential to reshape renewable energy economics while combating climate change. The investment underscores growing investor interest in non-lithium energy storage solutions amid a projected $300-600 billion market over decades. Energy Vault differentiates from battery technologies like Tesla's Megapack by targeting larger capacities of 20-80 MWh per tower at a levelized cost of 6 cents per kWh. Backed by prior investors including Neotribe Ventures, Cemex Ventures, and Idealab, the company emerged from years of development at the Pasadena incubator. At the time, Energy Vault had not built a full-scale prototype despite its short existence, yet attracted this unusually large sum signaling market validation for innovative storage amid global shifts from fossil fuels.
May-19Series ACEMEX Ventures--CEMEX Ventures announced its investment in Energy Vault on 16 May 2019. Energy Vault develops grid-scale energy-storage systems intended to store renewable electricity and release it when demand rises. At the time the company’s principal technology used mechanical lifting and lowering of composite blocks, and it later expanded into battery storage, software and owned energy assets. CEMEX Ventures linked the investment to collaboration on materials and industrialization. The official release names the firm as an investor but does not provide a transaction amount or identify a complete same-event syndicate. It expands the target’s resources for product development and market growth while preserving the named investor perimeter from the event source.

Description
The Goshe Energy Storage Portfolio is a United States pipeline of 15 battery energy storage projects with more than 2.3 GW of aggregate planned capacity. Approximately 350 MW was described as ready to build when Energy Vault announced the acquisition in September 2026. The portfolio adds projects across ERCOT and other United States power markets to Energy Vault’s Asset Vault strategy. Energy Vault acquired project-development rights and planned to apply its engineering, procurement and operating capabilities. The assets are designed to earn revenue from capacity, energy trading and grid-support services after construction. The record represents the acquired portfolio rather than the seller as a whole. The company serves professional or institutional customers and is represented here using the event-specific corporate identity. Its profile separates operating activity from the financing or acquisition itself. No unverified scale, customer count or financial metric has been added.
The BayWa r.e. Japan BESS Portfolio comprises eight utility-scale battery energy storage projects across Japan with approximately 850 MW of aggregate planned capacity. BayWa r.e. developed the pipeline before Energy Vault completed its acquisition in May 2026. The assets gave Energy Vault a development and operating platform in the Japanese electricity market. The portfolio is intended to provide capacity, balancing and renewable-integration services as individual projects reach construction and operation. Energy Vault classified the acquisition within its Asset Vault owned-asset strategy. The transaction transferred a project portfolio and associated development rights, not BayWa r.e. itself. The company serves professional or institutional customers and is represented here using the event-specific corporate identity. Its profile separates operating activity from the financing or acquisition itself. No unverified scale, customer count or financial metric has been added.
McMurtre BESS is a 175 MW grid-scale battery energy storage project in Texas. Belltown Power originated and developed the project before its acquisition by Energy Vault in March 2026. The asset is intended to participate in the ERCOT market through energy arbitrage and grid-support services. Energy Vault added it to the company’s owned Asset Vault development portfolio and planned to use its engineering and operating platform. The transaction concerned control of the project and its development rights. Revenue is expected from market participation and storage services after construction. The company serves professional or institutional customers and is represented here using the event-specific corporate identity. Its profile separates operating activity from the financing or acquisition itself. No unverified scale, customer count or financial metric has been added.
SOSA Energy Center is a 150 MW battery energy storage project in Scurry County, Texas. The project connects to the ERCOT power market and is designed to supply capacity, energy shifting and ancillary grid services. Savion developed the asset before Energy Vault acquired it in October 2025 from an affiliate of Shell. Energy Vault placed the project into its Asset Vault portfolio and planned to deploy its technology and operating platform. The transaction transferred a development-stage energy asset rather than an operating software company. Revenue is expected from power-market and grid-services contracts after construction and commercial operation. The company serves professional or institutional customers and is represented here using the event-specific corporate identity. Its profile separates operating activity from the financing or acquisition itself. No unverified scale, customer count or financial metric has been added.
