| Global energy needs, essential to the maintenance of life on our planet, are leading to a remarkable wear of non-renewable energy sources such as coal, oil, natural gas, or uranium. Until now the humanity has been devoted almost exclusively to consume the huge deposits of coal and oil generated over millions of years, thereby disrupting the cycle of carbon dioxide (CO2) and thereby contributing to the global warming, derived from the greenhouse effect whose consequences begin to manifest themselves. In a period of time for the tiny hope of life on Earth, estimated at about a billion years, these sources will be sold out; even the alternative resources, such as the oil shale and tar sands will have suffered the same fate. It is conceivable that before that is consumed this exhaustion, humanity will have resolved the problem of energy supply, as for example making it feasible nuclear fusion, which, at the moment, is too elusive to current techniques. In the meantime, the potential effects of climate change that we are living are very serious and, most importantly, irreversible. The world and Europe in general and Spain in particular, cannot afford to wait any longer and must pursue the ideal of a sustainable energy system and free of harmful emissions. While reaching the state of scientific and technical development necessary for a stable supply from nuclear fusion and bearing in mind that, with or without pollution, will be used in one form or another until the last gram of fossil fuel or nuclear, mankind is facing the problem of energy supply universal and clean. With the degree of current knowledge, the renewable energies can be the solution to the problem. The need to adjust the energy supply to the demand in general requires a stage of energy storage. This requirement is more evident than in the case of renewable energy from solar or wind power due to its nature of flashing caused by local weather conditions. The hydrogen is profiled in these moments as the most likely solution to the energy storage. This item is not a primary source of energy such as coal, oil or natural gas. Not found free in nature. This is a "conveyor of energy", such as electricity, so that, as she has to be produced from other forms of energy. Both electricity and hydrogen, are called "vectors" energy. Are forms of "noble" energy, and complementary: you can transform a in another, and take advantage of the benefits of each one of them over the other in the issues of storage, transport, production and use. Different applications of hydrogen for storage and energy vector has been compared to conclude that among the various options for energy storage, hydrogen is emerging right now as the most likely solution to energy storage, with great opportunities and capabilities. Keywords: hydrogen, energy storage, renewable | |
