This superb theme issue of Journal of Materials Chemistry is guest edited by Professor M. Saiful Islam (University of Bath, UK). 

One of the major challenges in the twenty-first century is the development of cleaner, sustainable sources of energy so it is now particularly timely to publish a focused set of articles covering the materials chemistry of energy-related applications. Issue 30 of Journal of Materials Chemistry highlights some of the latest research in energy conversion and storage technologies. It contains more than 20 articles on fuel cells, lithium-ion batteries, solar cells and hydrogen storage,  including several feature, application and highlight articles.

Contributors to this issue include: Raymond Gorte (University of Pennsylvania, USA); Linda Nazar (University of Waterloo, Canada); Sossina Haile (California Institute of Technology, USA); Peter Bruce (University of St Andrews, UK); Michael Thackeray (Argonne National Laboratory, USA); Yang Yang (UCLA, USA); Avelino Corma (Universidad Politecnica de  Valencia); Omar Yaghi (UCLA, USA); and many more.

The issue includes a 'hot' paper from Alberto Tarancón and collaborators; you can read an interview with Tarancón by following the link below.

Hong-Cai (Joe) Zhou from Miami University, Ohio, USA, also contributes to the issue. Read an "instant insight" article written by the author by following the link below, in which he describes how metal-organic frameworks could play their part in the hydrogen economy.
