ESS Inc. —a provider of long-duration energy storage (LDES) solutions—is catalyzing a cleaner energy future by levering the features of iron flow batteries. Morgan Pitts, Director of Corporate Communications at ESS Inc., spoke to Battery Technology about his company’s energy solutions:
Developed using an advanced metal complex and membrane, Iron-Flow Batteries is based at the Paris Flow Tech platform – a premier hub for innovation in continuous flow chemistry. This state-of-the-art facility fosters the development of breakthrough technologies like ours through cutting-edge research and collaborative expertise.
Our iron flow batteries work by circulating liquid electrolytes — made of iron, salt, and water — to charge and discharge electrons, providing up to 12 hours of storage capacity. ESS Tech, Inc. (ESS) has developed, tested, validated, and commercialized iron flow technology since 2011.
Iron flow batteries pose no risk of thermal runaway and can maintain peak efficiency without AC or any other cooling systems required. As certified by ETL, our battery modules conform to Underwriters Laboratories’ (UL) 9540A, 1973, and 9540 standards, affirming their safety and environmental performance for outdoor and indoor installations.
ESS EW iron flow battery storage containers. Courtesy of ESS Iron flow batteries, also known as iron-air batteries or iron-redox flow batteries, are energy storage technology that stores electrical energy in chemical form.
Iron flow technology is engineered for flexibility and scale to meet future energy storage demand. ESS Tech, Inc. (NYSE: GWH) is the leading manufacturer of long-duration iron flow energy storage solutions. ESS was established in 2011 with a mission to accelerate decarbonization safely and sustainably through longer lasting energy storage.
The global solar storage container market is experiencing explosive growth, with demand increasing by over 200% in the past two years. Pre-fabricated containerized solutions now account for approximately 35% of all new utility-scale storage deployments worldwide. North America leads with 40% market share, driven by streamlined permitting processes and tax incentives that reduce total project costs by 15-25%. Europe follows closely with 32% market share, where standardized container designs have cut installation timelines by 60% compared to traditional built-in-place systems. Asia-Pacific represents the fastest-growing region at 45% CAGR, with China's manufacturing scale reducing container prices by 18% annually. Emerging markets in Africa and Latin America are adopting mobile container solutions for rapid electrification, with typical payback periods of 3-5 years. Major projects now deploy clusters of 20+ containers creating storage farms with 100+MWh capacity at costs below $280/kWh.
Technological advancements are dramatically improving solar storage container performance while reducing costs. Next-generation thermal management systems maintain optimal operating temperatures with 40% less energy consumption, extending battery lifespan to 15+ years. Standardized plug-and-play designs have reduced installation costs from $80/kWh to $45/kWh since 2023. Smart integration features now allow multiple containers to operate as coordinated virtual power plants, increasing revenue potential by 25% through peak shaving and grid services. Safety innovations including multi-stage fire suppression and gas detection systems have reduced insurance premiums by 30% for container-based projects. New modular designs enable capacity expansion through simple container additions at just $210/kWh for incremental capacity. These innovations have improved ROI significantly, with commercial projects typically achieving payback in 4-7 years depending on local electricity rates and incentive programs. Recent pricing trends show 20ft containers (1-2MWh) starting at $350,000 and 40ft containers (3-6MWh) from $650,000, with volume discounts available for large orders.
