This is achieved using a fuel cell, which is the reverse process of electrolysis. The final step is the conversion of hydrogen into electricity, when needed. Hydrogen, and therefore the energy contained in it, can thus be stored without any particular time limit. ![]() For example, McPhy Energy, a French company, has developed a hydrogen storage solution using metal hydrides, which are chemical compounds of hydrogen with metal. Finally, hydrogen can also be stored in solid form. When cooled to an extremely low temperature, hydrogen is transformed into a liquid form enabling more convenient transportation by boat or truck. Hydrogen can also be transported in liquid form. In compressed form, hydrogen can be transported by truck or pipeline. To be more easily stored, hydrogen can be compressed to occupy less space. The produced hydrogen is conditioned in a tank with different technologies depending on the applications. The third step is the storage or transportation of hydrogen. Here, the combination of electricity and water will create a decarbonized hydrogen (on a gaseous form). The second step is the transformation of electricity into hydrogen, through water electrolysis for a green circuit. In order to achieve a green hydrogen circuit, the energy must be decarbonized, thus created from renewable energies or nuclear energy. This hydrogen energy vector process works in 4 steps.įirst, energy must be created, as hydrogen remains an energy vector, and only carries energy produced by another system. Indeed, hydrogen would be a “bridge” between primary energy sources and end usages. ![]() Hydrogen offers a huge potential as an energy vector. The main energy vectors used today are heat, electricity, compressed air, mineral oil, and of course hydrogen. In comparison, electricity is an energy vector widely used by industrialized countries to efficiently deliver energy in an easily usable form. Primary energy forms, meaning the energy forms naturally available in the environment before any transformation, such as fossil fuels are energy sources. It is important to understand that an energy vector does not produce energy it simply contains energy imbued by another system. Thus, an energy vector contains energy that can be later converted to other forms such as mechanical work and heat, or to operate chemical or physical processes, to generate electricity for example. An energy vector, or energy carrier, is a substance or a method to transport energy from one place to another and to stock it. ![]()
