Safe, low-cost and long-duration energy storage system that can extend the availability of intermittent renewable energy sources

ESS Inc is a leading manufacturer of safe, low-cost and long-duration energy storage systems, and is working on its second-generation iron flow battery technology.

  • There is a significant need for low-maintenance storage technology that can extend the availability of intermittent renewable energy sources like wind and solar.

  • ESS Inc. uses low-cost, safe and effective materials – iron and water – to deliver a long-duration storage solution in several applications, even high-temperature climates where there is a significant need for off-grid energy

  • The company has partnered with Munich Re to implement an industry-first insurance-backed warranty on its flow batteries. This investment-grade warranty coverage enables long-duration storage solutions to be more readily financed by project owners and developers.

ESS Inc.’s iron flow battery technology is a safe (no hazardous chemicals) and sustainable (fully recyclable) storage solution that is ideally suited for time-shifting renewable energy, managing a facility’s demand charges, providing ancillary grid services with unlimited cycling, and smoothing the intermittency of renewable on a constrained grid. These capabilities make it suitable to support large-scale renewable energy projects, as well as transmission- and distribution-level services, without cycling limits.

    Flow battery

    A flow battery is a cross between a conventional battery and a fuel cell. The liquid electrolyte of metallic salts is pumped through a space containing positive and negative electrodes separated by a membrane. The ion exchange that occurs between the cathode and anode generates electricity. Here’s a video on how a Vanadium Redox Flow Battery works

    Helping Utilities Reap the Rewards of Renewable Energy

    The EW has an energy storage capacity of 400 kWh, a 25-year design life, and can be configured with variable power to provide storage durations of 4 to 12 hours. These features make it ideal for traditional renewable energy and utility projects where long-life and unlimited cycling capabilities are desired. Concurrent with serving these applications, the EW’s inherent quick-response power electronics can perform ancillary grid services such as voltage and frequency support on microgrids.
