In recent years there has been increasing interest in the use of Earth abundant elements (C, Fe, Cu, Zn, Sn, Se, Te, Al etc) for a variety of energy system applications ranging from solar energy conversion systems to catalysts and electrocatalysts. The applications for these elements are many and varied. It should also not be forgotten that there has, for some time, been a significant amount of developing of materials such as hematite, copper oxide, and derivatives of tungsten oxide as well as functional materials such as barium titanate for energy conversion systems. These metal oxide systems are all derived from elements that are significantly more abundant than for example the platinum group or other (semi-)precious metals. The purpose of this symposium is to bring together pioneers, from both academia and industry, focusing on advances in developing novel materials combinations for energy conversion. The symposium aims to assemble leaders from various fields were materials developments are key to cross fertilise enabling a transfer of knowledge and understanding across some of the current technical research areas. Hence, this symposium will offer a particular emphasis on diversity of approach and novelty of materials application to enhance our understanding of what may be possible.
