Jofemar Energy, the division of Corporación Jofemar specialised in energy efficiency and storage, brought its Flow Grid project to a close last February with the presentation of the first version of their Zn-Br flow batteries. And it did so with promising results. The first versions have been designed, developed and tested at Jofemar’s facilities in Peralta, incorporating the latest improvements obtained including the use of nanotechnologies and the specific development of the main components for the electrochemical pairing. An output of 10 and 60 kWh, respectively, was achieved for operation in residential environments and smart grid integration.
The flow batteries are an electrochemical storage technology in a demo phase that is gradually approaching commercial phase. One of its distinguishing features is that this type of batteries can convert and store electrical energy as chemical energy and invert the process in a controlled way when required or necessary. This technology works as a result of the oxidation/reduction reaction produced by applying or taking an electric current from the two chemical species that oxidise and reduce, respectively, forming the REDOX system in a flow cell. These chemical species are called electrolytes. They are stored in external tanks and then pumped to the cell where the electrochemical reactions take place.Read more…
