Dr. Andrew L. Heyes, Imperial College London Dr. Yongliang Li, University of Leeds Dr. Christos Markides, Imperial College London ABOUT LIQUID AIR ENERGY NETWORK (LAEN) Dr. Rob Morgan, University of Brighton LAEN is a newly created forum to explore and Robin Morris, Independent Consultant promote the use of liquid air as an energy vector, with Stuart Nelmes, Highview Power Storage applications in grid electricity, transport and waste heat recovery. Nick Owen, E4tech Building on the findings of the Centre for Low Toby Peters, Liquid Air Energy Network Carbon Future’s report, LAEN will serve as the Anthony Price, Electricity Storage Network global hub where new ideas are demonstrated and shared, and promote liquid air as a potential energy John Raquet, Spiritus Consulting solution among researchers, technology developers, David Sanders, Cleantech Advisory manufacturers, energy producers and consumers, and government. Its membership will be drawn from Steve Saunders, Arup the same groups. To contact LAEN, please visit www. Dipl. Ing. Alexander Schlotmann, Messer Group liquidair.org.uk.
