Energy Vault EVx™ Gravity Energy Storage Technology Named a TIME Best Invention of 2024

WESTLAKE VILLAGE, Calif.--(BUSINESS WIRE)-- Energy Vault Holdings Inc. (NYSE: NRGV) ("Energy Vault" or the "Company"), a leader in sustainable, grid-scale energy storage solutions, is honored to announce the selection of its EVx gravity energy storage system (GESS) technology to TIME's Best Inventions of 2024 list, in the "Green Energy" category. This recognition highlights growing awareness of the need for reliable, cost-effective and sustainable energy storage solutions to meet global decarbonization goals, as well as the significant potential of gravity energy storage technology to play a key role in advancing the world's transition to clean, renewable energy.

"Energy Vault was founded with a vision to enable a sustainably energized world through the development of energy storage solutions that help utilities, independent power producers and large industrial energy users reduce the cost of abundant clean energy while maintaining power reliability," said Robert Piconi, Chairman and Chief Executive Officer of Energy Vault. "The selection of EVx to be a part of TIME's Best Inventions of 2024 list is testament not only to the immense potential this technology holds, but also to the dedication and commitment of the Energy Vault team to pursue our mission."

Energy Vault's EVx GESS systems are based on the proven physics and mechanical engineering fundamentals of pumped hydro, which currently accounts for about 90% of the world's energy storage capacity, but replace water with custom-made, environmentally-friendly composite blocks which do not lose storage capacity or degrade over time. The blocks can be made from low-cost and locally sourced materials, including the excavated soil at customer construction sites. Importantly, waste materials that traditionally must be remediated at considerable cost, such as mine tailings, coal combustion residuals (coal ash), and fiberglass from decommissioned wind turbine blades, can also be used to make the blocks, creating a circular economy that is both more economical and sustainable.

EVx decouples power and energy while maintaining a high round-trip efficiency exceeding 80%, without the need for specific topography. The result is a flexible, low-cost, 35-year (or more) infrastructure asset with a long technical life, zero degradation in storage medium, and modular architecture that can scale to multi-GW-hour storage capacity, enabling utilities, independent power producers and large industrial energy users to significantly reduce their levelized cost of energy while maintaining power reliability. The systems are automated leveraging Energy Vault's proprietary advanced computer control and machine vision software that orchestrate the charging and discharging cycles while meeting a broad set of storage durations starting from 2 hours and continuing to 12 hours, or more.

The EVx platform is prominent member of Energy Vault's G-VAULT™ suite of long duration gravity energy storage solutions, which also include EVu ™, EVc ™, EVy ™, and EV0 ™.

Energy Vault's EVx GESS technology, currently being commissioned in Rudong, China, will be the world's first grid-scale gravity energy storage system when fully operational. To date, nine EVx deployments are underway across China via a licensing agreement with China Tianying (CNTY) and Atlas Renewable, totaling more than 3.7 GWh.

Earlier this year, Energy Vault announced its expansion into Southern Africa with an agreement that includes multi-year license revenues and additional royalty revenue streams tied to gravity energy storage project deployments in South Africa and the broader 16 member-state Southern African Development Community (SADC) region.

Energy Vault also previously announced a global exclusive partnership with world-renowned architecture and engineering firm Skidmore, Owings & Merrill (SOM), to incorporate gravity energy storage technology into tall buildings in urban environments and deployable structures in natural environments, to maximize sustainability, accelerate carbon payback and lower the levelized cost of energy consumption.

To compile the TIME Best Inventions of 2024 list, nominations were solicited from TIME's editors and correspondents, and through an online application process, paying special attention to growing fields-such as AI, green energy, and sustainability. Each contender was then evaluated on a number of key factors, including originality, efficacy, ambition, and impact.
