Work is now underway on an energy storage scheme which could be the most significant energy breakthrough project in the last quarter of a century. It is the 50 MW liquid air storage plant in Manchester led by the company Highview. This (as yet small step) has a very good chance to pave the way for 100 per cent renewable energy systems in which sceptics who cite so-called intermittency from solar and wind as a barrier to providing total renewable energy supply are just blown away. I talked to one of the inventors of renewable energy to liquid air storage systems – known technically as cryogenic freezing of air into a stored liquid – Yulong Ding, about the technology. Yulong Ding is the founding Chamberlain Professor of Chemical Engineering at the University of Birmingham and his team has amassed some 70 patents covering various energy related technologies including storage. Cryogenic storage of air looks to me like it will be a total game-changer because of its ability to store, relatively cheaply and conveniently – renewable energy so that if there is no wind or sun then stored renewable energy can be fed back through a turbine to generate electricity.
