BMW Clean Energy system involves liquid hydrogen produced from water using solar energy. Hydrogen as a motor fuel is the answer to many environmental problems, since there are no harmful emissions, no depletion of resources, and there is no danger to the atmosphere.
Since the 70s, BMW has been researching the future of mobility. The fruit of research is the new BMW hydrogen vehicle 750hL.
The heart of the 750hL is a hybrid of 12-cylinder combustion engine with two separate electronic control systems for induction of fuel. These systems allow 750hL to run on either gasoline (petrol) or hydrogen.
The 750hL is a hybrid 12-cylinder combustion engine capable of running on either gasoline or hydrogen. 5.4 liters of engine has two independent, electronically controlled systems for induction of fuel. Hydrogen offers an excellent torque and acceleration, while the specially insulated tank 140 liters of liquid hydrogen offers a range of 400 kilometers.
The process of engine:
Electricity generated from solar energy is used to split water into hydrogen and oxygen. The oxygen is released into the atmosphere, while hydrogen is liquefied and stored at a very low temperature (-253 ° C).
During the internal combustion, hydrogen combines with oxygen. The resulting energy powers the vehicle, while the hydrogen is returned to the environment such as water. Harmful emissions are virtually eliminated.
By cooling hydrogen to -253 degrees Celsius, hydrogen is reduced to a thousandth of its original volume. 70 layers of aluminum foil and fiberglass between exterior and interior walls of the vehicle to ensure that the liquid hydrogen is maintained at extremely low temperatures.
