Electric cars with batteries together with hybrids have an important competitor. There are brands, the Orientals, BMW and others, who seriously think about a new option of electric vehicles. They are cars that generate electrical energy with the help of hydrogen. The electricity generator is a fuel battery. An electric power production system that was only used in spacecraft up to recent dates. The fuel battery is an electrochemical system in which, through the introduction of hydrogen and oxygen, an inverted electrolysis that produces electricity and water. The majority of that electrical energy goes to the engine. The rest is stored in a small battery. As for the water, in the form of steam, it is the only gas that comes through the exhaust tube. Therefore, if the hydrogen is obtained with the generated electrical energy, for example in a tanning factory, the process is zero missions.
Although hydrogen is not in free state, there are several ways to obtain it. Moreover, it is inexhaustible, it has a very low weight/volume ratio, it has considerable energy performance and is a zero mission fabric. If we look at refueling and autonomy, the hydrogen car has important advantages compared to the battery. The fuel loading time is the same as that of a petrol board, while for those of batteries we talk about loading times between 30 minutes and 4 hours. Autonomy is comparable or larger than that of conventional vehicles and surpasses a lot, compared to those of battery cars. The first discomfort is the limited number of service stations. The second, due to production and transport costs, the price per kilometer of hydrogen is higher than that of the rest of fuels. With regard to the risks, hydrogen is used safely in the industry. Refineries, large consumers, for example, use hydrogen as raw oil processing gas.
The inconvenience will gradually decrease in the coming years. There are data that indicates that the vehicle production price is reduced by half with large -scale productions. In addition, high -pressure hydrogen storage tanks are replaced by normal pressure storage in nanoporos that are composed of materials. Hydrogen production and transport will be reduced. It could even occur at the gas station. In Japan and Korea, taking into account the scientific-technological progress that occur and in the dedication to the hydrogen of their car manufacturers, they already have a few thousand cars that are circulating, thanks to some mini-sees of hydrogen service stations. In Europe, the ashes of the Alstond countries to France started the same path. Hydrogen or batteries? We will see.
