EnerVenue’s next-generation ESVs continue to deliver proven and demonstrable advantages over lithium-ion for grid-scale, commercial, and industrial deployments—with unique and unparalleled battery durability, safety, and operational flexibility. Next-generation ESVs have an ultra-long 30-year 30,000-cycle expected lifespan, and a projected 86% capacity after 30,000 full cycles. Because metal-hydrogen ESVs pose zero thermal runaway risk and no risk of fire propagation, deployments require no complex and costly fire suppression or robust HVAC systems.

The next-generation ESVs can flexibly cycle up to three times per day, at 2 to 12-hour discharge rates, enabling unique applications and business models for developers, integrators, and owners. Revenue stacking opportunities can also be maximized because of the solution’s applicability to so many clean energy use cases.

“Our new Energy Storage Vessels advance our solution’s energy capacity, density, and power performance, and continue to add to our battery’s advantages over lithium-ion systems,” said Majid Keshavarz, Chief Technology Officer, EnerVenue. “As lithium supply chain problems and other factors continue to threaten its long-term viability in stationary storage, ESVs offer clear differentiation. Our metal-hydrogen solution uses Earth-abundant materials and, in contrast to lithium-ion systems, does not require augmentation to maintain performance over the battery’s 30-year, 30,000-cycle lifespan. Fire-prone lithium-ion systems also require robust HVAC and fire suppression systems that our next-generation ESVs do not, reducing customers’ cost and operational requirements.”

The next-generation ESVs are backed by EnerVenue’s Capacity Assurance™, the industry’s longest, simplest, and most straightforward extended warranty for stationary batteries, offering an unmatched 20-year/20,000 cycle warranty extension that guarantees at least 88% battery capacity remaining after that period.

Certifications and standards testing on the new ESVs is underway. The batteries will be produced at the company’s one-million-square-foot gigafactory in Shelby County, Kentucky, where the plant is being designed with manufacturing lines to support production at scale. Already backed by large-scale deals from Pine Gate Renewables, Nicon Industries’ Green Energy Renewable Solutions and others, volume manufacturing and the new design of EnerVenue’s next-generation ESVs are expected to significantly accelerate profitability for the company.

EnerVenue Launches Energy Storage Vessels (ESVs), the Second-Generation of its Metal-Hydrogen Energy Storage Solution

The ESVs offer more efficient and flexible deployments of EnerVenue’s pioneering technology, with scalable and customizable large-format battery configurations ready to meet a wide breadth of customer and partner applications

FREMONT, Calif. – Dec. 6, 2022 – EnerVenue, the first company to bring metal-hydrogen batteries capable of more than 30,000 cycles to the clean energy revolution, today announced the launch of EnerVenue Energy Storage Vessels (ESVs), the company’s second-generation energy storage product.

EnerVenue ESVs continue to expand the company’s pioneering use of metal-hydrogen energy storage technology as an advantageous solution compared to lithium-ion and other alternatives. Based on decades of use with NASA and other aerospace applications, EnerVenue has significantly cost-reduced materials to bring—for the first time—unique battery durability, safety, and flexibility benefits to grid-scale, commercial and industrial deployments. The new ESV solution delivers unprecedented flexibility in how customers can stack and install the vessels to build and scale their energy storage capacity.

The ultra-long-life EnerVenue ESVs enable unique applications and business models for developers, integrators, and owners. Customers can cycle ESVs up to three times per day without rest, and the batteries have an expected lifetime of 30 years / 30,000 cycles. ESVs continue to deliver 86% capacity beyond 30,000 cycles, providing a second asset life that lithium-ion batteries cannot match. The solution’s metal-hydrogen technology further differentiates from li-ion by offering improved fire safety. ESVs have been tested and demonstrate no thermal runaway or propagation risk, and there is no need for costly, preventative fire suppression systems. EnerVenue ESVs also significantly reduce OPEX and CAPEX costs compared to li-ion, delivering on expected ROI by eliminating any need for expensive augmentations, excessive oversizing, or extensive maintenance during a project’s lifetime. With recyclable components, ESVs are also more sustainable and environmentally responsible than li-ion.

EnerVenue ESVs offer a highly configurable and scalable product architecture that makes the products ideal building blocks for system integrators of all sizes and business models. ESVs similarly enable a more flexible breadth of deployment locations—and are built to thrive even in extreme temperatures and other environments where grid-scale li-ion batteries struggle. The product also features flexible charge/discharge rates and can discharge to 100% (deep discharges permanently damage li-ion batteries), giving system owners the latitude to capitalize on a broader range of revenue stream opportunities.

“Our new ESVs deliver a meaningful upgrade to the customization and ease with which customers and partners can plan—and expand—their utilization of our transformative and proven battery technology,” said Majid Keshavarz, Chief Technology Officer, EnerVenue. “As the applications using our technology have grown, we wanted to ensure we had a product that could match almost any use case. ESVs package EnerVenue’s incredible technology into a more flexible and efficient solution that we’re excited to bring to market.”

EnerVenue’s metal-hydrogen battery systems enables energy providers and system owners with proven grid-scale renewable storage technology that rectifies the cost, durability, and safety limitations of lithium-ion. Li-ion batteries suffer from significant and problematic battery degradation—with power output falling several percent per year—and energy providers using li-ion must regularly perform expensive mitigations by adding new battery banks to their existing footprints to keep up with their contractual power output obligations. Li-ion warranties reflect this risk with their cost and complexity – usually requiring operation in a very narrow specifications window and containing myriad exclusions and exceptions.

In direct contrast, EnerVenue’s battery systems offer a 30+ year design life with essentially zero year-to-year degradation. With no augmentations required, EnerVenue’s batteries are ultra-low maintenance, with similarly low material and operational costs. Importantly, EnerVenue’s batteries present no fire or thermal runaway risk, exhibit extremely minimal degradation and are built to operate in a wide range of ambient temperatures without auxiliary HVAC.

“For years, the stationary storage market has been asking for a simple, long-term capacity guarantee,” said Randy Selesky, CRO, EnerVenue. “Capacity Assurance delivers an industry-best promise that complements EnerVenue’s robust technology and provides our partners with both operational confidence and contractual security.”
