Hydrogen is called to be one of the fuels of the future, a possible substitute for gasoline or diesel, and an alternative to electric plug-in cars. Although only one model, the Hyundai Nexo, can currently enroll in Spain, and although the number of possible refueling points can be counted on the fingers of one hand, in Europe and Asia this technology is taking more and more weight . In addition, you can not deny the doubts that this fuel generates, both for its profitability and its safety in everyday use. That is why Javier Brey, president of the Spanish Hydrogen Association, resolves many of the myths that surround this chemical element as fuel for cars of the immediate future.
