Hydrogen Vehicles and Their Delay in Production

Our air is our future. Hydro The latest trend is today's hybrid car. People are looking for alternatives to gasoline cars and have chosen a more fuel-efficient car. As gasoline prices rise and become increasingly dependent on foreign oil, it is necessary to take some measures and complete quickly. Finally, we may finally find a solution, hydrogen car. Will it outweigh the electric cars and electric cars we have today? During his first term, President Bush proposed $ 1.2 billion for hydrogen car research funding.

The number of hydrogen cars currently produced is wonderful. Toyota delivered 3,000 Mirais in 2016, this number will be exceeded in 2017 and by 2020 the car will be in mass production. More cars are also from Honda and Hyundai. There are Chinese automobile manufacturers such as Super Automobile Group, BYD Auto, Great Wall Motor etc. The Chinese government announced plans to build a hydrogen energy infrastructure by supporting up to 1 million FCEV by 2030.

Fuel cell vehicles combine hydrogen fuel and oxygen from air to produce electricity. It is then used to propel the car and the only exhaust is water. Emissions are generated in the production of hydrogen fuel, and most of the hydrogen is now coming from the conversion of natural gas. Fuel cell vehicles are quiet and quiet, but they are still in the early stages of development and have become popular on our roads for several years.

Liquefied hydrogen is the liquid state of elemental hydrogen. It is a common liquid rocket fuel for rocket applications and can be used as fuel in internal combustion engines or fuel cells. Hydrogen carriers of various concepts have a lower volumetric energy and a large amount of hydrogen necessary for combustion. In 1898, James Dewar liquefied hydrogen for the first time. Ammonia (NH 3) is used as fuel before gasoline becomes available (such as Belgian buses during World War II). It has a volumetric energy density of 17 MJ per liter (10 for hydrogen, 18 for methanol, 21 for dimethyl ether, and 34 for gasoline). Although it does not require cryogenic cooling to liquefy hydrogen, it must be compressed or cooled to liquid fuel.

Hydrogen storage is a major challenge, especially for the development and practicality of hydrogen vehicles. Hydrogen is the lightest element and occupies a larger volume than other fuels. Therefore, it needs to be stored in a liquefaction, compression or advanced storage system to ensure that the vehicle has enough distance for the vehicle to travel. Technological advances to replace storage options, including the development of advanced materials such as carbon nanotubes and metal hydride complexes
