Present in the oceans and the stars, it is the most abundant element of our planet and of the entire universe. Paradoxical as it may be, the limited availability of pure hydrogen in the gaseous state has been the main obstacle for the development of cells capable of mobilizing vehicles.
For hydrogen to generate electricity, it is necessary to tap into non-renewable resources, such as complex hydrocarbons. By decomposing the molecule of natural gas, for example, hydrogen is obtained, but also carbon dioxide, the maximum responsible for global warming. The process sounds reasonable until we learn the cruel reality: the amount of energy used is greater than what we will get once we use hydrogen.
