In order to achieve the goals set up by DECC to drastically reduce carbon dioxide emissions by 2050 it is imperative togenerate a large amount of electricity via renewable sources. Being of an intermittent nature, the renewable sources forelectricity generation require installation of energy storage devices. Redox flow cells are considered to be a strongcandidate to store energy in the range of few kW/kWh up to tens of MW/MWh. An innovative technology, patented anddeveloped by Imperial College London, has demonstrated excellent performance using a redox flow battery based on thereaction of hydrogen (gas) and vanadium (liquid), and the feasibility of combining this innovative chemistry into cells andstacks developed by Arcola Energy will be explored in this project, along with the potential value of the technology for gridscale storage application (by Alstom UK).
