Holdings, Inc. (NYSE:NRGV) ("Energy Vault" or the "Company"), a global leader in sustainable, grid-scale energy storage solutions, today announced the publication of its 2025 Corporate Sustainability Report (the "report"), highlighting significant operational achievements, strategic market expansion, and continued progress on environmental, social, and governance (ESG) priorities.
Energy Vault achieved an ESG score of 74 out of 100 from S&P Global in 2025, representing a five-point improvement from the Company's 2024 score of 69 and placing Energy Vault in the 98th percentile of the Machinery and Electrical Equipment (IEQ) industry. This performance maintains the Company's position as the highest-ranked energy storage company in the IEQ industry. Additionally, Energy Vault continues to advance its climate leadership with near-term and long-term emissions reduction targets that have been validated by the Science Based Targets initiative ("SBTi").
"2025 marked a pivotal year for Energy Vault as we expanded our Asset Vault platform and achieved significant operational milestones that demonstrate our commitment to enabling a sustainably energized world," said Robert Piconi, Chairman and Chief Executive Officer, Energy Vault. "Through the expansion of our build-own-operate strategy, strategic partnerships in the rapidly growing AI and data center sectors, and continued innovation across our differentiated technology portfolio, we are advancing our position as a global provider of resilient energy infrastructure. As we publish our 2025 sustainability report, I'm proud of our sustainability leadership in energy storage and remain confident that Energy Vault will drive the global energy transition forward."
Energy Vault's sustainability framework centers on three core pillars – Purpose, Product, and Partnership – which shape how the Company designs technologies that reduce emissions, enable renewable energy adoption, and deliver long-term value for its customers and communities. The Company's Triple Bottom Line approach is embedded throughout its product lifecycle strategies to help ensure its team and stakeholders are empowered to make conscientious decisions that balance financial health with environmental impact and social accountability.
"Our successful transition to an Own & Operate strategy has fundamentally transformed how we approach sustainability, giving us direct responsibility to measure and optimize the environmental performance of our energy storage systems through initiatives like our Sustainable Sites Management Plan and real-time carbon tracking," said Michael Van Parys, Energy Vault's Director of Sustainability. "As we maintain our leadership position — evidenced by achieving the highest sustainability score among energy storage companies in S&P Global's Yearbook — we're moving beyond reporting to implement truly impactful programs that advance our unchanged mission: to enable a sustainably energized world. From the BESS systems powering communities to the powered land and powered shells enabling the AI infrastructure of tomorrow, sustainability is not a layer we apply on top of our work — it is built into every decision we make."
"Energy Vault embeds sustainability across every critical infrastructure asset it builds, owns, and operates — because accelerating long-term human prosperity and maintaining an unwavering focus on environmental responsibility are, for the Company, inseparable goals," added Piconi. "From utility-scale battery energy storage systems to powered land and powered shells that provide the foundational energy infrastructure behind the AI revolution transforming our society, Energy Vault is proud to be best-in-class in this effort. The Company sees its role not only as an energy infrastructure provider, but takes on its responsibility for the betterment of our planet as a moral imperative— one that can serve as a source of inspiration for the next generation of engineers, entrepreneurs, and sustainability leaders shaping the world ahead."
The 2025 report highlights significant operational milestones achieved during the year, including the opening of Energy Vault's Solutions Excellence Center with gravity demonstration units, the commissioning of the Cross Trails Resiliency Center, the Company's first fully owned and operated battery energy storage system, and strategic market entries in Australia and Europe. The Company also announced over 3 GWh of deployed or contracted systems in its global B-VAULT portfolio and secured $300 million in investment to finance critical energy infrastructure assets.
Energy Vault's commitment to global sustainability frameworks includes participation in the UN Global Compact, alignment with the Task Force on Climate-related Financial Disclosure (TCFD) and Global Reporting Initiative (GRI) standards, and implementation of an internal carbon pricing mechanism.
