European Marine Energy Centre heralds a triple first project – flow battery, tidal power and hydrogen! Just how many innovations can you pack into a project? Well not many more than the tidal power-flow battery hydrogen project that is set to be deployed at the European Marine Energy Centre in Orkney! But perhaps newest of all, it is an important step forward towards developing techniques, in this case flow batteries, to store renewable energy in the long term. Flow batteries represent an important step forward for energy storage in that they offer the prospect for much cheaper long term storage of renewable energy. Flow batteries are much better at long term storage compared to the now ubiquitous lithium ion battery. That’s because, as an article in Science Magazine put it: ‘They store electrical charge in tanks of liquid electrolyte that is pumped through electrodes to extract the electrons; the spent electrolyte returns to the tank.
