The world largest motor-car manufacturers BMW, Toyota, Honda, GM, DaimlerChrysler and Volkswagen have developed automobiles with the hydrogen engine, however all companies have faced technological problems, such as high value up to $1 one million per one unit.
The problem is that the hydrogen filled as a liquid in a fuel tank at the lowest temperature turns to gas in process of its heating and evaporates in air even if the vehicle is not used.
“After the certain period of time, a week for example, the tank will be empty. It is the certain difficulty, but we work on it “, - has told Franc Ohmann, the vice-president BMW on pure technologies.
Ohmann told, that BMW carries out tests of a fuel tank in which hydrogen can be kept in a liquid state.
Engineering of filling stations for vehicles with hydrogen engines isn’t a big problem, experts consider. Hydrogen is already delivered to the industrial enterprises in tankers or through the pipelines.
Ohmann said, that BMW company believes, that the large-scale production and sale of autos with hydrogen engines will begin not earlier than 2025.

• Honda will produce the hydrogen engine car
• The new technology can transfer automobiles to hydrogen fuel
• Scientists invented a new way of hydrogen obtaining from water
• Hydrogen car has made a unique long run
