A hydrogen vehicle, also known as a fuel cell vehicle (FCV), is an alternative fuel vehicle that uses hydrogen fuel for electricity. These cars arguably can solve the problem of reducing greenhouse gas emissions and transportation due to fossil fuels. In this guide, we explore the basics of hydrogen cars, how they work, their advantages and challenges, and the current state of their development.
How do hydrogen cars work?
Hydrogen cars use a machine called a fuel cell to generate electricity.
Fuel cells combine hydrogen stored in a pressurized tank with oxygen from the air to produce electricity, water and heat. This process is called electrochemical conversion. The electricity produced by the fuel cell powers the car's electric motor, which propels the car forward. Therefore, hydrogen powered vehicles have zero exhaust emissions and the only byproduct is water vapor.
Hydrogen vehicles have the potential to play a role in future transportation, but there are many factors to consider when assessing their potential.
Advantages of Hydrogen Cars:
Zero Emissions: Hydrogen fuel cell cars only produce water vapor as a byproduct, which makes them promising in reducing internal and external emissions.
Variety and refueling time: Hydrogen cars generally have a longer range than battery electric vehicles (BEVs) and can be refueled quickly, similar to petrol cars.
Faster energy: Compared with batteries, hydrogen has faster energy and can store more energy.
Challenges and Decisions:
Infrastructure: One of the biggest problems facing hydrogen cars is the lack of refueling infrastructure. Building a network of hydrogen refueling stations requires significant investment and time.
Production and storage: The production of hydrogen is often based on processes that require a lot of energy and cause carbon emissions. Also, storing hydrogen safely and efficiently remains a challenge.
Cost: Currently, hydrogen cars are more expensive than gasoline cars and electric cars.
To make these cars more affordable, the cost of fuel cell technology and hydrogen production needs to be lowered.
With electric cars gaining pace in the market, H2 vehicles face fierce competition. The electric vehicle industry has seen significant advances in battery technology, increased charging and lower costs. However, hydrogen and electric vehicles can be combined and meet different transportation needs according to various needs and budgets. Nature pays for the equipment.
The future of transportation will involve a combination of technologies, including hydrogen, electricity and other fuels, depending on the region and specific market.
