As it battles to scale up its proprietary iron electrolyte flow battery technology, ESS Inc has only reported revenues once before, in Q1, of US$400,000 but in Q2 this jumped to US$2.8 million. This article requires Premium Subscription Basic (FREE) Subscription
Its innovative iron flow battery technology supports renewable energy generation by providing energy storage that can discharge for up to 12 hours, with an operating life of more than 20 years. Unlike conventional Li
The Iron Redox Flow Battery (IRFB), also known as Iron Salt Battery (ISB), stores and releases energy through the electrochemical reaction of iron salt. This type of battery belongs to the class of redox-flow batteries (RFB), which are alternative solutions to Lithium-Ion Batteries (LIB) for stationary applications.
South Korea-based H2, Inc will deploy a 1.1MW/8.8MWh vanadium flow battery (VFB) in Spain in a government-funded project. Li-ion BESS from Fluence, iron-air batteries from Form Energy put through fire testing paces. Peak Energy announces sodium-ion engineering centre in Colorado.
The Iron Redox Flow Battery (IRFB), also known as Iron Salt Battery (ISB), stores and releases energy through the electrochemical reaction of iron salt. This type of battery belongs to the class of redox-flow batteries (RFB), which are alternative solutions to Lithium-Ion Batteries (LIB) for stationary applications. The IRFB can achieve up to 70% round trip energy efficiency.
An order for 8.5MWh of iron electrolyte flow battery energy storage systems (ESS) has been received by US manufacturer ESS Inc from Enel Green Power''s Spanish arm. Enel Green Power España will deploy the flow battery capacity — contained in 17 separate ESS Inc Energy Warehouse systems — at a solar PV power plant.
"ESS Inc.''s long-duration iron flow battery will greatly reduce the need to run generators to meet demand. We also highly value that the system is safe, earth-friendly, and will operate at full capacity for at least 20 years without replacement – these were critical decision factors," GRUPO SAESA''s marketing manager Marcelo Bobadilla
The aqueous iron (Fe) redox flow battery here captures energy in the form of electrons (e-) from renewable energy sources and stores it by changing the charge of iron in the flowing liquid electrolyte. When the stored energy is needed, the iron can release the charge to supply energy (electrons) to the electric grid.
Shares and warrants of iron flow battery provider ESS Inc have commenced trading on the New York Stock Exchange (NYSE). Shareholders in special purpose acquisition company (SPAC) ACON S2 Acquisition Corp voted to approve a business combination with ESS Inc, which then went ahead and created the combined, NYSE-listed entity.
NYSE-listed iron flow battery group ESS Inc is expanding into Europe with its first deployments on the continent later this year and local manufacturing capability expected by 2024/25. The company is scheduled to
Long-duration energy storage (LDES) is the linchpin of the energy transition, and ESS batteries are purpose-built to enable decarbonization. As the first commercial manufacturer of iron flow battery technology, ESS is delivering safe, sustainable, and

The VRFB is the most common type of flow battery, using vanadium pentoxide electrolyte, but rival chemistries exist, including zinc-bromine, iron and saltwater. A handful of flow battery makers have not revealed their electrolyte chemistries but used terms such as ''organic electrolyte'' or not hinted at all, and Unbound Potential falls into
Vanadium redox flow battery (VRFB) manufacturer VRB Energy intends to build two factories in China through a joint venture (JV) and one in the US through a new subsidiary. Queensland invests in Australia''s first ''14-hour'' duration iron flow battery factory
ESS Inc, the US-headquartered manufacturer of a flow battery using iron and saltwater electrolytes, has launched a new range of energy storage systems starting at 3MW power capacity and promising 6-16 hours
ESS Inc shares listed on the New York Stock Exchange in October. Image: ESS Inc via Twitter. ESS Inc''s recent special purpose acquisition company (SPAC) merger, which listed the iron flow battery manufacturer''s shares and warrants on the New York Stock Exchange, has raised US$246 million cash.
Though, another flow battery provider, ESS Inc, provided a written statement in response strongly contesting this (ESS Inc''s technology uses iron and salt rather than vanadium). The minor debate came at a time when lithium-ion costs were increasing for the first time in a decade, but this trend reversed in 2023 back to the norm of cost falls.
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.
The iron flow battery''s first deployment in Australia is underway through a partnership between ESI and Queensland government-owned energy company Stanwell Corporation. A 1MW/10MWh system is being trialled at a Stanwell energy innovation hub, with installation underway since late last year.

The European energy storage market is booming with Germany leading residential adoption (+58% YoY) thanks to €500/kWh subsidies. Italy's new tax credits drive 5.2GWh commercial deployments, while UK grid-scale projects exceed 8GWh with 2-hour duration systems. Key selection criteria: German-certified safety (VDE-AR-E 2510), 10+ year warranties, and VPP readiness. Top-performing products include Sonnen's hybrid inverters (98% efficiency) and BYD's Blade Battery (12,000 cycles @80% DoD). For snowy regions like Scandinavia, consider Huawei's -30°C compatible systems. France mandates carbon footprint declarations - Sungrow's ISO-14067 certified solutions gain preference.
For European homeowners, 5-10kWh systems with 3-phase compatibility are ideal. Top picks: 1) Tesla Powerwall 3 (13.5kWh, 97% round-trip efficiency) for smart home integration; 2) LG Chem RESU Prime for compact urban installations; 3) SMA Sunny Boy Storage for retrofit projects. Critical features: EU-made battery cells (exempt from CBAM tariffs), dynamic tariff optimization (like Octopus Energy integration), and fire-safe LiFePO4 chemistry. Southern Europe demands 85%+ depth of discharge capability, while Nordic markets require -25°C operation. Always verify CEI 0-21 compliance for Italian grid connection and EnWG certification for German feed-in.
