CRF researchers presented four papers at the 5th International Conference on Hydrogen Safety, held September 9–11 in Brussels, Belgium. ICHS 2013 focused on progress in safety of hydrogen technologies and infrastructure, as crucial/essential means to enable the transition to a zero carbon energy system. The conference was hosted by the Joint Research Centre (Institute for Energy and Transport) of the European Commission. The papers will be published in a special edition of the International Journal of Hydrogen Energy. The papers were
