Aquion is changing the way the world uses energy by delivering stationary energy storage systems that are high performance, safe, sustainable, and cost-effective. Their batteries are engineered and manufactured in the USA, with research stationed at Carnegie Mellon University.

Flexible, Scalable Energy Storage

Aquion’s Aqueous Hybrid Ion (AHI™) battery systems are optimized for stationary, long duration daily cycling applications. This includes off-grid and microgrids, energy management, and grid-scale energy storage applications. Aquion’s battery systems provide flexible, modular energy storage that optimizes existing generation assets and enables broad adoption of renewable energy technologies such as wind and solar. Aquion’s economically compelling batteries can be assembled into systems ranging from kilowatt-hours to megawatt-hours.

Aquion Batteries Outlive & Outperform Traditional Batteries

The patented Aqueous Hybrid Ion (AHI™) battery technology provides high performance, safe, sustainable, and cost-effective energy storage for long-duration stationary applications.

Energy Storage,
Clean & Simple.

Aquion’s technology is based on a simple idea: In order to meet the challenges of the world’s growing energy needs and increase the use of renewable power, we need large-scale energy storage systems that are high performance, safe, sustainable and cost-effective. The company founder, Professor Jay Whitacre, set out to solve this problem and discovered a simple and elegant solution that is a twist on a 200 year-old technology: saltwater batteries. Aquion developed this solution into our patented Aqueous Hybrid Ion (AHI™) chemistry, a unique saltwater electrolyte battery technology. Using abundant, nontoxic materials and modern low cost manufacturing techniques, our AHI batteries are now ready to take on the global energy storage challenge.

Unmatched Performance

Aquion’s battery technology offers thousands of real-use application cycles for long duration (4 to 20 hour) applications. The batteries are extremely tolerant to abuse with the ability to stand at a partial state of charge with minimal degradation. The system requires no costly thermal management or regular maintenance and contains no hazardous materials, corrosive acids, or noxious fumes.

A Unique Chemistry

Our unique Aqueous Hybrid Ion (AHI) chemistry is composed of a saltwater electrolyte, manganese oxide cathode, carbon composite anode, and synthetic cotton separator. The battery utilizes non-corrosive reactions at the anode and cathode to prevent deterioration of the materials. The water-based chemistry results in a nontoxic and non-combustible product that is safe to handle and environmentally friendly.

Bulk Energy Storage for
Large-Scale Applications

Aquion’s modular, scalable batteries are designed for large-scale energy storage systems and offer flexibility in configuration options. Aquion’s M-Line Battery Modules have the footprint of a standard pallet, making them compatible with most high-density racking systems. The M-Line Modules are scalable for a wide range of interior configurations. This enables Aquion and its partners to design and deploy large systems in a way that optimizes space and leverages existing logistics infrastructure. Aquion’s systems are based on proprietary Aqueous Hybrid Ion (AHI™) technology which delivers aunique combination of performance, safety, and sustainability in a cost-effective battery system.

Enabling New Possibilities

Aquion’s AHI batteries are the much-needed solution for stationary, long-duration, daily cycling applications. Designed to meet the needs of existing and emerging storage applications, AHI batteries enable new possibilities for off-grid, microgrid, energy management, and grid service applications.

Microgrids range in generating capacity from kW’s to MW’s and provide power to a variety of users ranging from small cell phone towers to large commercial, industrial and military customers. Energy storage is used to enhance the stability and efficiency of microgrids by decoupling the generation source from the load. This is particularly useful for systems with diesel generation or intermittent renewables as the means of electricity production.
