Energy Vault Closes Series B Funding With $110 Million Investment From Softbank Vision Fund

New Financing Will Accelerate Growth and Rapid Global Deployment of Company’s Transformative Utility-Scale Energy Storage Technology

LUGANO, Switzerland–(BUSINESS WIRE)–#EnergyStorageTowerEnergy Vault, the creator of renewable energy storage products that are transforming the world’s approach to long duration, utility-scale energy storage, today announced it has completed a $110 million Series B funding round. The investment for the round was made by SoftBank Vision Fund (Vision Fund) in its first investment in energy storage technology. Energy Vault will use the funds to accelerate global deployment of its technology, which – for the first time – enables renewables to deliver baseload power for less than the cost of fossil fuels 24 hours a day. As part of the investment, Andreas Hansson, Partner for SoftBank Investment Advisers, will join the Energy Vault board of directors.


Renewables have struggled historically to fully replace fossil fuel power as a result of production unpredictability and intermittency from reliance on variable factors such as wind and sunlight. In the absence of more efficient and cost-effective storage, the amount of electricity that can be delivered to the grid from renewable energy sources, even though now widely affordable, has been limited.

Energy Vault’s breakthrough technology was inspired by pumped hydro plants that rely on the power of gravity and the movement of water to store and discharge electricity. The company’s solution is based on the same well-understood fundamentals of physics and mechanical engineering used in those plants, but replaces water with custom made composite bricks through an innovative use of low-cost materials and material science. The bricks, each weighing 35 metric tons, are combined with Energy Vault’s proprietary system design and machine vision software to operate a newly designed crane. The software autonomously orchestrates the energy storage tower and electricity charge/discharge utilizing predictive intelligence and a unique stack of proprietary algorithms that account for a variety of factors, including energy supply and demand volatility, grid stability, weather elements and other variables. As a result, the Energy Vault tower can deliver all the benefits of a large scale pumped hydro storage system, but at a much lower levelized cost, higher roundtrip efficiency and without the requirement for specific land topography and negative environmental impacts.

Energy Vault has experienced significant growth since its launch in November 2018. In addition to the previously announced agreement with The Tata Power Company Limited, India’s largest integrated power company, Energy Vault will be demonstrating the first 35MWh storage tower in the north of Italy in 2019. The company has also developed an extensive relationship with CEMEX (NYSE: CX) that includes a technology collaboration and development agreement with CEMEX Research Group AG (Switzerland) as well as an investment from CEMEX Ventures announced in May 2019. As a further measure of the unprecedented market demand and upcoming adoption of the technology, Energy Vault has agreements with customers on four continents.

“Energy Vault solves a long-standing and complex problem of how to store renewable energy at scale,” said Akshay Naheta, Managing Partner for SoftBank Investment Advisers. “The company’s integration of proven technologies with 21st century material science and machine vision software provides a solution that reshapes the unit economics of renewable energy while being restorative to the environment. Energy Vault is highly complementary to SoftBank’s existing energy portfolio and we are pleased to further the company’s global development.”

“As we pursue our mission to enable renewable energy to replace fossil fuels 24 hours a day, we’re thrilled to partner with SoftBank Vision Fund as we expand our global presence,” said Robert Piconi, Chief Executive Officer and Co-Founder, Energy Vault. “The Vision Fund shares our passion to combat climate change through innovation in energy storage technologies and, with its support as a strategic partner, Energy Vault is well positioned to meet the large and currently unmet demand for sustainable and economical energy storage worldwide.”
