However, since hydrogen cars accumulate their energy storage densely, they can generally travel longer distances. While most fully electric vehicles can travel 100 to 200 miles on a single charge, hydrogen vehicles can travel 300 miles, according to Automotive Technologies.
Hydrogen fuel cell
electric vehicles could be the best option for medium to large and long-range vehicles. During electrolysis, water molecules, which contain hydrogen and oxygen, split and hydrogen atoms are captured and used to power the FCEV fuel cells.Director of the Helmholtz Institute for Electrochemical Energy Storage in Ulm and designated expert in hydrogen research, he recently told the “Wirtschaftswoche” that the “very poor energy efficiency of the well behind the wheel of the fuel cell car ensures that electric cars that run on batteries “demand a multiple or more efficient”. In addition, in the event of a fire, batteries can ignite and are difficult to turn off, since the fuel in the fire is not expelled as is the case with hydrogen. Hydrogen production is an energy-efficient chemical process that produces fuel cells with a two- to three-fold performance advantage compared to internal combustion engines. The manufacture of hydrogen fuel cells is not much better, since the fuel cells of the Toyota Mirai are equivalent to 120 g of CO2 per kilometer, although this can be significantly reduced if renewable energy is used to produce hydrogen.
While the process for producing hydrogen gas can be complex, it is the most abundant element in the universe, meaning that hydrogen is a renewable fuel source. The technology behind hydrogen fuel cells is extremely sophisticated and impressive, and the hydrogen cars that exist in the real world are comfortable and easy to drive, but there are significant obstacles for hydrogen cars as a whole. On the other hand, green hydrogen refers to hydrogen that is produced through the use of renewable energy through a process known as “electrolysis”. In addition, hydrogen cars are actually electric cars, but they have their own power plant on board, so it could be said that electric energy is advantageous, since it is this form of drive that is ultimately used by hydrogen cars.
Hydrogen vehicles are more expensive than electric vehicles, and there are currently no economic options on the market. The price of a new hydrogen vehicle is comparable to that of a high-end electric vehicle. However, it seems that this will also change, as the cost of hydrogen fuel cells has already fallen by more than 80% in recent years. This includes the development of technologies for electric cars and those that work with hydrogen fuel cell technologies.
Hydrogen cars also contain an electric motor, which runs on hydrogen fuel cells that allow hydrogen to react with oxygen to create the chemical production of electricity and water vapor. Hydrogen is then released in what is known as a “fuel cell”, and here an anode and cathode divide hydrogen molecules into protons and electrons.
