Hydrogen Engine – Technology of the Future

Contrary to the popular belief that a hydrogen engine is something new in the energy sector and is able to force oil out of the market, it’s not true.

The car manufacturers started to use hydrogen as fuel back in the 60s of the XX century, but they ended up producing prototypes only. Indeed, the use of hydrogen has always been unprofitable because in order to extract hydrogen from the air it is necessary to use a lot of electricity. As a result, a liter of hydrogen is 2 times more expensive than a liter of gasoline, and the car itself costs hundreds of thousands of dollars. That’s why a lot of people would rather tend to purchase bmw 5 whichconsumes gas.

Hydrogen cars have nothing to do with the technology of the future such as thermonuclear synthesis, they are only a variation of an electro mobile.

The principle of hydrogen engine operation is relatively simple. There are fuel cells which are installed between the cylinder with hydrogen and the engine. Inside these fuel cells there is a membrane, an anode and a cathode. The hydrogen is fed to the anode, and oxygen to the cathode (from the air), and by means of the catalyst integrated into the membrane, hydrogen is divided into protons and electrons. In the process of partition, there is a difference in potentials – electricity. On the cathode side, hydrogen protons are oxidized by oxygen and water vapor is obtained, which is the only car exhaust.

A balloon for hydrogen can withstand even a bullet hit of 12.7-mm diameter and if an accident happens, there isn’t any explosion.

The Japanese manufacturers, who have recently launched the production of cars with a hydrogen engine, the Toyota Mirai model, managed to reduce the cost to $50 thousand. But it’s still too expensive to talk about the beginning of the hydrogen era. The ecological value of such vehicles is also questionable: when producing hydrogen, there are as many harmful emissions as in the combustion of oil fuels are emitted, so this model is not yet easy to describe as a promising project.

There are two tanks for storing hydrogen under a pressure of 70 MPaunder the hood of the car. The maximum distance of a trip at one gas station is 650 kilometers, and the maximum speed of a car reaches 175 km / h. Time of full refueling of two cylinders is only 3 minutes. The cylinders are made of composite materials and are protected from damage during an accident.

Demand for hydrogen cars exceeded expectations

A month later, after the presentation of a hydrogen car, Toyota received 1,500 orders for this model, which is 2.5 times higher than expected. Interestingly, the other day the Japanese giant announced that it would promote the development of the industry of such cars.

If you think that it’s too early to invest in new technologies, you can check Toyota Camry or Nissan Rogue prices on the Internet and buy a traditional car.
