Nowadays, society and the economy largely depend on wireless communications because they allow freedom of human activities from spatial and temporal restrictions. To add mobility to this communication technology type, portable communication networks can be implemented to achieve this aim as well as to provide ubiquitous coverage in emergency circumstances. In accordance with the above-mentioned points, we study a photovoltaic-hydrogen system (PVS-H2) for a portable emergency communication system (PECS), which operates in a mobile ad-hoc mesh network. As a case study, a theoretical application on the effects of two hurricanes per year in Cancun, Mexico using real weather data and random dates is presented. A power system was sized to cope with hypothetical emergency communication scenarios. The results show that the PVS-H2 can operate during two hurricanes with an efficacy of 79.14% and a standard deviation of 0.96%. According to the results, the analysis strategy can determine the best configuration to avoid oversizing or undersizing with a small standard deviation. The obtained sizing result ensures that the PVS-H2 supplies adequate energy for the PECS. Copyright (c) 2015, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd. All rights reserved.
