Finding new ways empowering global vehicles has been a key factor in tackling the climate crisis. When it comes to small passenger cars, there is no question that the future will be full of battery-powered cars, not those powered by hydrogen fuel cells — another possible option. However, the size of the car is getting bigger, hydrogen can be a very attractive option. For buses, some argue that hydrogen power offers several important advantages over its battery-powered counterparts. Which of them, if any, is the master of the buses and has the power to control the flow of traffic?
Battery-powered cars and hydrogen fuels have the same operating system. All of them save energy to build an electric engine. However, in the end, the energy stored as hydrogen is converted into electricity by a fuel cell, instead of being stored in a rechargeable battery.
Selling electric cars reached 3 million by 2020, has risen by 40 percent since 2019, with 10 million electric vehicles currently on the world’s roads. Hydrogen vehicle registration remains three levels lower than this, and it exists Only 26,000 On the road worldwide, he settled in three countries: Korea, the US (especially California), and Japan. Although there are a number of hydrogen fuel cars available on the market, manufactured by Toyota and Hyundai, they are more expensive than electric cars and currently can be difficult to burn: Hydrogen is more expensive to buy, and there is a long way to go. less fuel production area compared to additional fuel stations in many areas.
But when it comes to large vehicles, the picture is bleak. As cars get older, it can be difficult to install electricity, when batteries are needed. For energy-intensive activities such as long-distance vehicles, some experts say hydrogen can be a very effective alternative.
Buses are located somewhere between cars and trucks at this distance. “The big issue is the number of buses,” says James Dixon, a researcher in the field of electrical engineering and transportation at Oxford University. “Batteries have a very small density: Electricity is about 1/40 of the capacity of hydrocarbon fuel, such as gasoline or diesel.” Hydrogen also has a very low energy content (amount of energy that can be stored per unit volume mass or region) —about four to five times more than petroleum fuel, but much higher than electric batteries, he adds.
China has already done so about 5,300 hydrogen fuel cell buses on its roads, the majority of ships around the world, but some countries are investing professionally. Neil Collins, chief executive of Wrightbus in Northern Ireland, says his company is a professional manufacturer of hydroelectric power buses. It feeds the travel information from the bus driver to a tool that demonstrates the various driving directions of its vehicles, helping them find the best professional route on the route.
The benefits of hydrogen include shorter duration of refueling and larger tanks. But hydrogen technology and construction are far more expensive, says Collins, while the technology developed in the electric bus industry is even higher than that of hydrogen. Dixon also says that one thing about hydrogen has always been its safety. He states: “It has a very high limit of combustion, and it is extremely difficult to store it in a stress-free container. “When it comes to construction, electricity is simple, because you don’t need fuel trucks.”
