Can a car run on hydrogen gas? The simple answer to that question is yes. However, there are several technical challenges to running a car purely on hydrogen gas (H2). The main issue is storage. To save a sufficient amount of H2 to power the vehicle, it must be compressed into cylinders under high pressure tank. This will create problems if there are leaks and dangerous for drivers because the H2 is highly flammable. Another way to use hydrogen in cars is to apply the “need” system. What is the science behind the concept? This article will provide some useful information on the topic.

It is fact that you can save fuel by converting your car to run on hydrogen gas. To overcome the problem of gas storage, the car can be installed with the electrolysis. This device is basically used to extract H2 from water. This is possible because water is made ​​of two hydrogen molecules and one oxygen atom. For electrolysis to work, it must be connected to car batteries. The entire circuit can be connected to the switch board.

When the light is turn on, hydrogen gas is generated and discharged into the engine intake air system. From there it is sucked into the combustion chamber and mixed with gasoline. Due to the nature of strong H2, the gas mixture will burn more efficiently and produce more power. By completing the hydrogen gas into the engine, it has the potential to increase vehicle mileage thus saving costs.

Hydrogen “on demand” system work manually. When the car is moving, the driver turns on the switch to conserve fuel. When the car is idle, the electrolysis system is turned off to stop the production of hydrogen gas. With simple setup, drivers around the work have the opportunity to convert their cars to run on hydrogen.
