Company to showcase industry-leading portfolio of economic and sustainable solutions and product offerings engineered to increase the financial and environmental value of customers’ energy assets

Energy Vault Holdings, Inc. (NYSE: NRGV) ("Energy Vault" or the "Company"), a leader in sustainable, grid-scale energy storage solutions, will be presenting its full suite of sustainable energy storage solutions and products at the RE+ conference in Las Vegas, Nev. from September 12-14, 2023, at The Venetian Convention & Expo Center. Energy Vault representatives will brief RE+ attendees on the Company's transformative energy storage hardware, software and solutions designed to meet customers' unique needs for short, long, and ultra-long duration energy storage.

"Our goal at Energy Vault is to provide customers with a comprehensive portfolio of energy storage solutions, products and services that are not only sustainable and cost-effective, but are also tailored to meet customers' specific needs," said Marco Terruzzin, Chief Commercial and Product Officer, Energy Vault. "Our customer-centric, solutions-based approach to energy storage starts with the problem our customer is trying to solve and then brings together the right components to deliver customized solutions to achieve their goals for renewable energy deployment and decarbonization. This is what sets us apart as leaders in the transition to a renewable world. We look forward to connecting with RE+ attendees this week in Las Vegas and discussing how we can solve their unique challenges."

Energy Vault's customer-centric solutions portfolio is built upon a portfolio of proprietary energy storage system technologies, and an open stack energy management software based on the VaultOS™ (operating system to control/dispatch the Energy Storage Solution), the Vault-Manager™ (software to minimize maintenance cost) and the Vault-Bidder™ (AI enabled software to maximize net-revenues). The Company works directly with customers to identify the energy storage hardware systems that will best meet their needs, and then integrates flexible software solutions designed to monitor and control customers' specific energy storage systems, minimize maintenance costs, and maximize net revenues. With modern architecture, Energy Vault's tech stack unlocks the value of energy storage solutions by continuously optimizing grid integration as use cases evolve over time.

Hardware Offerings

G-VAULT™ - Energy Vault's long duration energy storage hardware solutions, G-VAULT™, consists of a proprietary gravity energy technology to deliver long technical life, high round-trip efficiency, low lifetime cost, and no degradation. The Company's EVx™ Gravity Energy Storage System (GESS), currently being deployed for the first time in Rudong, China, decouples power and energy while maintaining a high round-trip efficiency, without the need for specific topography. The result is a flexible, low-cost, 35-year (or more) infrastructure asset designed for daily bulk energy shifting without any storage medium degradation.
B-VAULT™ - Engineered to meet short duration energy storage needs, B-VAULT™ is a suite of fully integrated Battery Energy Storage Systems (BESS) designed for reliability, flexibility and availability. Innovative enclosure architecture provides customer optionality with both battery and inverter suppliers, while unique AC-coupled and DC-coupled configurations provide the drop-in flexibility needed for any project. Advanced safety and cybersecurity features combine with native VaultOS™ EMS integration and competitive project pricing to deliver on customer needs. Energy Vault is currently deploying B-VAULT™ systems across the United States.
H-VAULT™ - For customers' ultra-long duration energy storage needs, Energy Vault's H-VAULT™ system features hybrid configurations leveraging green hydrogen and batteries, to ensure continuity and resilience for backup and Public Safety Power Shutoff (PSPS) events. By coupling the long duration and fast response capabilities of green hydrogen, fuel cells, and B-VAULT™️ lithium-ion batteries, H-VAULT™ provides the clean, reliable, cost-effective back-up power that is critical to enable islanded microgrids during transmission outages. Energy Vault is currently deploying H-VAULT™ in Calistoga, Calif. to energize PG&E's Calistoga microgrid during grid outages.
Software Offerings

VaultOS™ Energy Management System (EMS) - VaultOS™ EMS provides real-time monitoring, operational control and optimized dispatch across an array of generation and short to ultra-long duration energy storage assets. The user interface makes it easy for customers to securely manage a single asset, hybrid power plant or fleet of resources at a glance while minimizing operational costs.
Vault-Manager™ - the Vault-Manager™ software constantly monitors energy storage system operations to aid customers in minimizing maintenance costs. Vault-Manager™ enables customers to optimize the long-term operation of renewable, hybrid and other diverse sites; improve site and portfolio return on investment (ROI); and analyze augmentation and expansion decisions.​
Vault-Bidder™ - the Vault-Bidder™ AI-enabled software allows customers to optimize net revenues associated with energy storage and deployment across markets. Vault-Bidder™ uses artificial intelligence to leverage diverse, live data from directly monitored assets and external drivers to provide dispatch and revenue optimization.
Long Term Service Offerings

Energy Vault leverages asset and fleet level data to plan ahead to maximize uptime. Targeting maintenance windows least likely to impact revenue potential, Energy Vault's long-term service agreements meet customers where they want to be - both now and in the future - by recognizing and balancing tradeoffs between cost and levels of risk management.
