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:
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.
ESS iron flow battery solutions are the most environmentally responsible and cost-effective energy storage systems on the market. Designed for 25-year operating life with minimal annual operations and maintenance (O&M) requirements 1.Haoyang, He et. Al. Flow Battery Production: Materials selection and environmental impact.
THE TIME HAS COME FOR STORAGE. ESS iron flow battery solutions are the most environmentally responsible and cost-effective energy storage systems on the market. Designed for 25-year operating life with minimal annual operations and maintenance (O&M) requirements
The company has already delivered a 1 MW/10 MWh iron flow battery to a site next to Stanwell Power Station, in a deal with Queensland’s state-owned energy generation business Stanwell Corp. Closer to home, ESS Inc. has a partnership with global conglomerate Honeywell.
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.
