A hydrogen vehicle is a type of alternative fuel vehicle that uses hydrogen as its onboard fuel for motive power. Hydrogen vehicles include hydrogen internal combustion engine vehicles and fuel cell vehicles, which convert hydrogen into electricity to power electric motors.

Types of Hydrogen Vehicles

There are primarily two types of hydrogen vehicles:

• Hydrogen Internal Combustion Engine Vehicles (HICEV): These vehicles use a modified internal combustion engine to burn hydrogen fuel.
• Fuel Cell Vehicles (FCV): These vehicles use a fuel cell to convert hydrogen into electricity, which then powers an electric motor.

Hydrogen Production and Storage

Hydrogen can be produced from various sources, including natural gas, biomass, and electrolysis of water. The storage of hydrogen in vehicles is typically done in high-pressure tanks.

Advantages

• Environmental Benefits: Hydrogen vehicles produce zero tailpipe emissions, with water vapor being the only byproduct.
• Energy Efficiency: Fuel cell vehicles are generally more efficient than traditional internal combustion engine vehicles.
• Renewable Energy Integration: Hydrogen can be produced using renewable energy sources, reducing dependence on fossil fuels.

Challenges

• Infrastructure: The lack of widespread hydrogen refueling stations is a significant barrier to the adoption of hydrogen vehicles.
• Cost: The production, storage, and distribution of hydrogen can be expensive.
• Energy Density: Hydrogen has a lower energy density compared to traditional fuels, requiring larger storage volumes.

Current Market and Future Prospects

Several automakers, including Toyota, Honda, and Hyundai, have developed hydrogen vehicles. The future of hydrogen vehicles depends on advancements in technology, infrastructure development, and policy support.

Energy development is the field of activities focused on obtaining sources of energy from natural resources. These activities include production of conventional, alternative and renewable sources of energy, and for the recovery and reuse of energy that would otherwise be wasted. Energy conservation and efficiency measures reduce the demand for energy development, and can have benefits to society with improvements to environmental issues.

Societies use of energy

Societies have long history of using energy, which has evolved from human and animal power, to the use of water wheels and windmills, to burning wood and coal for heat. In the industrial age, use of steam power and internal combustion engines led to an increase in energy use. In the 20th century, use of oil, natural gas, nuclear power and fossil fuels increased dramatically. In the 21st century, there is increasing use of renewable energy, such as solar and wind power, and a decrease in use of coal.

Sources of energy

Energy development is the ongoing effort to provide sufficient primary energy sources and secondary energy forms for supply, cost, impact on air pollution and water pollution, mitigation of climate change with renewable energy.

Non-renewable energy

Non-renewable energy sources include fossil fuels and nuclear power. Fossil fuels, such as coal, oil and natural gas, are used in everything from cars to electricity generation. Nuclear power uses the energy from nuclear fission or fusion to generate heat and electricity.

Renewable energy

Renewable energy sources include wind, solar, hydro, and geothermal energy. These sources are constantly replenished and will never run out. They also have a lower impact on the environment compared to non-renewable sources.

Energy conservation

Energy conservation refers to efforts made to reduce energy consumption. This can be achieved through increased efficient energy use, in conjunction with decreased energy consumption and/or reduced consumption from conventional energy sources.
