Energy without Limits.
Peak Energy is America's first vertically Integrated Energy Storage company.
We’ve solved the final constraints of Cost, Safety, and Reliability—making it possible for Battery Storage to scale with the grid and support the explosive growth of AI, manufacturing, and electrification. Our Sodium-Ion technology is specifically engineered for stationary storage: it’s safer, lower-cost, and free from the critical mineral dependencies that have long bottlenecked lithium-based solutions.
Peak's Summary
What we do
Peak Energy Engineers, Scales and Deploys the Best Energy Solution in the World.
Peak Energy designs, manufactures, and delivers next-generation energy storage systems that enable the rapid, reliable, and resilient growth of the electricity grid.
At the core of our platform is a proprietary sodium-ion technology, purpose-built for grid-scale applications. Our chemistry—NFPP sodium iron pyro-phosphate phosphate —is the building block for an inherently safe, passively cooled system - free from the thermal risks and rare material dependencies of lithium-based systems. It requires no auxiliary power, no active maintenance, and no fire suppression — making it ideal for dense urban settings, remote deployments, and critical infrastructure alike.
We operate across the entire energy storage value chain. From cell R&D and manufacturing to system integration and grid interconnection, our model is vertically integrated and designed for execution. Every component—from cathode to inverter—is optimized to reduce cost, speed up deployment, and maximize long-term reliability.
Our systems are modular and scalable, built for fast assembly and automation. We don’t just supply batteries — we deliver fully operational, site-ready solutions that reduce total cost of ownership from day one.
With fully domestic manufacturing in the U.S., take-or-pay customer contracts, and a clear path to 20+ GWh of annual capacity, Peak is redefining how storage is built and deployed. Our work supports the expansion of AI infrastructure, the decarbonization of power systems, and the resilience of communities facing increasing grid instability.
We deliver what the future demands: clean, compact, cost-effective storage that’s safe to deploy, easy to scale, and ready now.
Peak's History
Who we are
At Peak Energy, we are building the future backbone of the electricity grid.
Founded in 2023, our mission is to deliver safe, scalable, and domestically produced energy storage that meets the explosive demand from AI, data centers, electrification, and renewable power. The grid can’t evolve without storage — and we’re delivering the system that makes that possible.
Our sodium-ion platform is purpose-built for grid-scale deployment: inherently safe, low-cost, easy to install, and free from the supply chain fragility of lithium-based systems. Designed from the cell up, it’s the first truly industrial storage solution for a world in transition.
We’re more than a battery company — we’re a full-stack energy storage manufacturer led by veterans from Tesla, NRG, Fluence, and Enovix. Our team has scaled gigafactories, launched public companies, and deployed over 100 GWh of energy systems globally.
Since launch, we’ve secured commercial contracts that triple our initial capacity, and begun scaling domestic manufacturing. By 2030, we’ll deliver over 20 GWh of annual storage capacity, powering data centers, grid infrastructure, and resilient communities — all while creating 1,200+ U.S. jobs.
This is not just about batteries. It’s about building the infrastructure of a more powerful, autonomous, and connected world. And we’re doing it — now.

Peak Energy Delivers First Grid-Scale, Sodium-Ion Battery Storage System in the U.S.
Denver, CO
Today, Peak announced the launch and shipment of its sodium-ion battery energy storage system (ESS) that delivers a patent-pending passive cooling design to dramatically reduce lifetime energy costs. Cost-competitive with state of the industry products while offering dramatically lower operating and maintenance costs, Peak Energy's product is the first ever fully passive megawatt-hour scale battery storage system, the largest sodium-ion phosphate pyrophosphate (NFPP) battery system in the world, and the first grid-scale sodium-ion storage solution ever deployed to the U.S. electric grid. Deploying the system in a shared pilot with nine leading utility and independent power producer (IPP) customers this summer, Peak Energy is fast-tracking its promise to onshore battery manufacturing.

Temasek's Xora Innovation leads $55M Series A funding round in US battery maker Peak Energy
Singapore
Peak Energy has closed a $55M Series A led by Xora Innovation, with participation from Eclipse, TDK Ventures, and new strategic investors. The funding will accelerate full-scale sodium-ion system production and break ground on Peak’s first U.S. giga-scale sodium-ion battery factory, slated to open in 2027. Pilot deployments begin next year with six premier customers — including three of the nation’s top five independent power producers — marking a pivotal step toward U.S.-produced, utility-scale sodium-ion storage.

Clean Tech Veterans from Tesla, Northvolt hatch plan to mass-produce huge batteries to store solar and wind energy
Denver, CO
Peak Energy, founded by veterans of Tesla, Northvolt, and Enovix, has launched with a $10M seed round led by Eclipse and joined by TDK Ventures. The company is scaling sodium‑ion battery production in the U.S. to deliver cost‑competitive, grid‑scale storage for wind and solar energy. Unlike traditional startups, Peak is focused on rapid manufacturing scale-up of proven technology. The team brings deep experience in gigafactory design, operations, and financing—drawing on a track record of multi‑billion‑dollar scale at Tesla and Northvolt. Sodium‑ion batteries offer a safer, lower‑cost alternative to lithium‑ion for stationary applications, without the constraints of energy density that affect EVs. By manufacturing domestically, Peak strengthens supply chain resilience and reduces geopolitical and transport risks. Peak will deploy its first systems in 2024, targeting “double‑digit gigawatt” cell production by 2030 to support the U.S. grid’s growing need for energy storage.
We’ve solved the final constraints of Cost, Safety, and Reliability—making it possible for Battery Storage to scale with the grid and support the explosive growth of AI, manufacturing, and electrification. Our Sodium-Ion technology is specifically engineered for stationary storage: it’s safer, lower-cost, and free from the critical mineral dependencies that have long bottlenecked lithium-based solutions.
