Environmental Impact
Emissions During Operation
When it comes to emissions during operation, hydrogen vehicles are the clear winner. While electric vehicles produce zero emissions during operation, they are often charged using electricity generated from fossil fuels. This means that the production of electricity to charge electric vehicles results in greenhouse gas emissions. On the other hand, hydrogen vehicles emit only water vapour and heat during operation, making them a cleaner alternative to electric vehicles.
Lifecycle Greenhouse Gas Emissions
When considering the lifecycle greenhouse gas emissions of hydrogen and electric vehicles, it becomes clear that hydrogen vehicles are the more environmentally friendly option. A study by the International Council on Clean Transportation found that the lifecycle greenhouse gas emissions of hydrogen vehicles are up to 30% lower than those of electric vehicles [1].
This is because the production of electric vehicles is energy-intensive, and the production of their batteries requires the mining and processing of materials such as lithium, cobalt, and nickel, which can have significant environmental impacts.

When it comes to energy efficiency, hydrogen vehicles have a clear advantage over electric vehicles. In this section, we will discuss the fuel cell efficiency and energy conversion process of hydrogen vehicles that make them more energy-efficient than electric vehicles.
Fuel Cell Efficiency
Hydrogen fuel cell vehicles convert chemical energy from hydrogen and oxygen into electrical energy, which powers the vehicle’s electric motor. This energy conversion process is highly efficient, with fuel cell vehicles achieving up to 60% efficiency in converting hydrogen into electricity. In contrast, electric vehicles are less efficient, with most battery-powered electric cars and other vehicles boasting around 80% efficiency. This means that for every 100 watts of energy produced, nearly 80 watts will be used to power the vehicle.
Energy Conversion Process
The energy conversion process of hydrogen vehicles is also more efficient than that of electric vehicles. In electric vehicles, energy is stored in batteries, which are charged by plugging the vehicle into an electrical outlet. During the charging process, some of the energy is lost due to resistance in the charging cables and the battery itself. This results in a lower overall energy efficiency compared to hydrogen vehicles.
In contrast, hydrogen fuel cell vehicles generate electricity on demand, using hydrogen and oxygen to create electricity through an electrochemical reaction. This means that there is no need for energy storage, resulting in a more efficient energy conversion process.
Overall, the energy efficiency of hydrogen vehicles is superior to that of electric vehicles due to their high fuel cell efficiency and efficient energy conversion process.

Refuelling Time
One of the biggest advantages of hydrogen vehicles is the refuelling time. While it can take hours to fully recharge an electric vehicle, refuelling a hydrogen vehicle takes only a few minutes. This is because hydrogen can be compressed and stored in a tank, whereas batteries need to be slowly charged.
Hydrogen Production and Distribution
Hydrogen production and distribution is an area where there is still a lot of work to be done. However, there are already some promising developments. For example, hydrogen can be produced from renewable sources such as wind, solar, and hydro power. This means that hydrogen vehicles have the potential to be completely emissions-free.
In terms of distribution, there are already hydrogen refuelling stations in operation, and more are being built. While the infrastructure is not yet as extensive as that for electric vehicles, it is growing rapidly. For example, the UK government has announced plans to invest £500 million in the development of hydrogen vehicles and infrastructure.
In conclusion, while there are still some challenges to be overcome, hydrogen vehicles have some clear advantages over electric vehicles when it comes to infrastructure and refuelling. With continued investment and development, we believe that hydrogen vehicles have the potential to become a major player in the future of transportation.
