Solutions for a Sustainable Future.
VISION
Transforming U.S. Energy Storage for a Clean Energy Future
Nautilus Energy Technology, Inc. (Nautilus) is dedicated to revolutionizing the energy storage ecosystem in the United States through advanced sodium-ion battery technology powered by Artificial Intelligence (AI). Our mission is to develop utility-scale energy storage solutions that are more cost-effective, safer, environmentally sustainable, and offer a more stable supply chain compared to lithium-based alternatives. At Nautilus, we are committed to pioneering a domestic supply chain for longer-duration battery energy storage systems (BESS), driving innovation, and ensuring a cleaner, more reliable energy future for all.
OUR SOLUTION: SODIUM-ION BESS
Cost-effective, Grid-scale, Uncompromisingly Sustainable
SODIUM-ION: THE NEW ENERGY FRONTIER
↓ Cost
↑ Performance
Sodium-ion batteries provide a trifecta of lower costs, high performance, and safety. Using cheap, abundant materials available in the U.S., they can deliver long-duration storage at half the cost of lithium-ion systems. Sodium-ion batteries offer outstanding performance in terms of longer life, flexible working temperatures, and safety.
GIGA-SCALE
= Energy Density
as LFP
↑ More Scalable
than LFP
From both technology and commercial perspectives, sodium-ion battery technology can enable widespread deployment of long-duration energy storage. With production equipment and processes similar to LFP, sodium-ion batteries can be produced at giga-scale to meet growing grid demands. Our sodium-ion energy storage systems excel in multiple environments and use cases, offering extended duration and reliability.
SUSTAINABLE ENERGY STORAGE
↑ More Sustainable
↓ Lower CO2 Footprint
Sodium-ion technology redefines sustainability in energy storage. Made from abundant materials like salt and iron, it's free from the conflict minerals and toxic elements that come with lithium batteries. With simpler recycling, sodium-ion batteries offer a less environmentally impactful solution for the massive scale the future grid needs.
WHY NAUTILUS
Innovating Sodium-Ion Battery Energy Storage, Manufacturing, and U.S. Supply Chain
Proudly based in Mid-America (St. Louis), Nautilus is pioneering U.S. long-duration energy storage with smart, AI-powered sodium-ion Battery Energy Storage Systems (BESS) solutions for grid-scale applications. We're focused on advancing technical maturity and commercialization, optimizing performance, and reducing costs alongside our utility and other end-user partners. We are designing for manufacturability and developing a U.S. supply chain strategy to pave the way for a better, more sustainable, cost-effective, and safer energy storage future.
