What Are Hydrogen Cars ? Current Developments & Future Prospects

Hydrogen cars are vehicles that use hydrogen as fuel to power an electric motor. Hydrogen is stored in a tank and is combined with oxygen from the air in a fuel cell to produce electricity, which powers the motor. The only byproduct of this process is water vapor.

Advantages of hydrogen cars over conventional fuel cars include zero emissions, greater range, and faster refueling times. However, the availability of refueling stations, the cost of refueling, and potentially less efficiency than batteries are some of the disadvantages.

Current developments include a growing number of policies and projects around the world that support hydrogen fuel cell technology. The number of countries with policies that directly support investment in hydrogen technologies is increasing, along with the number of sectors they target. Global spending on hydrogen energy research, development, and demonstration by national governments has also risen.

The future prospects for hydrogen cars are promising. Clean hydrogen is currently enjoying unprecedented political and business momentum, with the number of policies and projects around the world expanding rapidly. The International Energy Agency produced a landmark report to analyze the current state of play for hydrogen and to offer guidance on its future development. The report finds that now is the time to scale up technologies and bring down costs to allow hydrogen to become widely used.

The two main hazards from fuel cell and hydrogen-powered vehicles are electrical shock and fuel flammability. Fuel cells power vehicles by electrochemically combining hydrogen gas (H2) and oxygen (O2) from the surrounding air into water (H20) and electrical energy. The flammability of hydrogen is also an issue. Hydrogen has a flammability range between 4% to 75% in air, which is very wide compared with other fuels (gasoline is to 7.6%). Under optimal combustion conditions, a small spark will ignite it.

In conclusion, while hydrogen cars have many advantages over conventional fuel cars, there are still some risks and hesitations associated with them. However, with growing support for hydrogen fuel cell technology worldwide, it seems likely that they will play an increasingly important role in our clean and secure energy future.
