, has been commissioned to deliver a new form of battery for a project in Spain. The order comprises 17 of ESS' long-duration warehouse iron flow battery systems for a hybrid project in Spain.to support a solar farm currently under construction. ESS' innovative system will have a combined capacity of 8 MWh to provide resilience for the local power grid.
The contract will be delivered in collaboration with the global systems firm Loccioni and engineering firm Enertis.According to ESS, their iron battery utilizes iron, salt, and water for the electrolyte to store energy for future use. Liquid electrolytes are circulated to charge and discharge electrons via a process called redox reduction.
The word “redox” is a contraction of the words “reduction,” which represents a gain of electrons, and “oxidation,” or a loss of electrons., their system"uses the same electrolyte on both the negative and positive sides of the equation, eliminating cross-contamination and degradation. This is why ESS chemistry remains stable for an unlimited number of deep-cycle charge and discharge cycles.
The technology is, of course, patented and comes with its own control system. It also dispenses with the need for a series ofMost PopularIron-flow batteries are clean, reliable, and cost-effective over the long term,
