Energy Storage for Off-grid and Microgrid 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. 

Aqueous Hybrid Ion (AHI™) Energy Storage

Aquion’s batteries are designed to meet the rigorous requirements of off-grid and microgrid applications. The batteries have excellent cycle life even at high depths of discharge, reducing the need for system oversizing and costly battery replacements.  Aquion’s abuse tolerant batteries deliver reliable performance across a wide temperature operating range without the need for costly thermal regulation and extensive monitoring equipment. 

High efficiency and long stands at partial states of charge with minimal degradation makes AHI batteries perfect for long duration, daily cycling applications like renewables support and diesel genset optimization.  Aquion’s unique combination of performance, cost, safety and sustainability results in industry-leading total cost of ownership (TCO) for off-grid and microgrid applications.
