Our present-day energy system is dominated by the systematic exploitation of large reservoirs of carbonbased fossil fuels. Although fossil fuel reserves are expected to last several centuries at the current rate of consumption, the rate of global climate change is the primary driving force behind the search for large-scale renewable energy sources. However, a major shortcoming in the utility of renewable sources of energy is the disparity in the geographic locations (and/or timings) associated with the production and demand for energy. This necessitates the development of energy storage solutions in different media, which can then be transported to the region of demand in order to ensure an uninterrupted supply of energy. Even batteries that promise large storage capacities fall short in the context of storage for extensive time periods, as well as their low gravimetric energy density. On the other hand, hydrogen which only yields water upon combustion, has a high gravimetric energy density of 28.68 kcal/g (approx. 3× gasoline), and is thus a prime candidate for large-scale applications in the automotive industry.
