Recent years have seen an increasing demand for fossil-fuels and consequent mounting damage to the environment. With this increasing demand the need for a renewable alternative source of energy is required. Hydrogen has been highlighted as an interesting alternative energy carrier showing both practical and economic advantages, particularly when used in conjunction with a hydrogen fuel cell . Whilst there has been much progression in the clean and renewable production of hydrogen through; biomass gasification, photoelectrolysis and also electrolysis using energy derived from renewable sources [2,3], a challenge remains for the storage and delivery of hydrogen for small and mobile applications. This mini-review discusses a range of viable C1 hydrogen storage materials and focuses on the key publications, as well as recent additions to the literature, related to the ruthenium catalysed release of hydrogen as this is one of most intensively researched areas of the field. Current progress in the homogeneous ruthenium catalysed reduction of CO2 is also discussed.
