A car is powered by an internal combustion engine burning hydrogen (usually obtained by decomposition of methane or electrolysis of water) and oxygen from the air to produce energy .
Water vehicles are hypothetical vehicles that do not require the use of gasoline or other fuels, but can use water for energy. They claim not to pollute the environment at all, but they are currently not recognized by the general public. science. Water-powered vehicles include hydrogen-powered vehicles, which are powered by an internal combustion engine burning hydrogen (obtained by decomposition of methane or electrolysis of water) and oxygen from water. 'air.
In 2009, Nissan launched a new FCV plan in Japan. Later, in October, Nissan, Ford Motor, General Motors, Hyundai Group, Toyota, Daimler, Renault and Kia Motors issued a joint statement for the developmentopper. Fuel battery car, completed in 2015. In 2011, Hyundai Group announced its Blue Fuel Cell Vehicle (FCEV), launched in 2014.
Detailed information:
Applications of hydrogen vehicles:
1. The emissions are pure water and produce no pollutants when driving. The cost of hydrogen fuel is too high, and the storage and transportation of hydrogen fuel is technically very difficult because hydrogen molecules are very small and can easily escape through the storage device housing.
2. Hydrogen extraction requires the electrolysis of water or the use of natural gas, which also require a large amount of energy, unless nuclear energy is used for extraction, emissions of carbon dioxide cannot be fundamentally reduced.
3. The power sources mainly include lithium-ion batteries, nickel-metal hydride batteries, fuel cells, lead-acid batteries and supercapacitors. Most supercapacitors come in the form of auxiliary power sources. The main reason is that these battery technologies are not yet completely mature or have obvious flaws. Compared with traditional vehicles, there are many gaps in cost, power and cruising range. This is also an important reason that limits the development of new ones. energy vehicles.

Geography Why is Japan rich in water power ?
March 1996. Construction of the Kamirukawa pumped storage power plant in Japan began in May 1997 and was officially commissioned.service in March 1996. A pumped storage power plant is a hydroelectric plant that uses electrical power to pump water to an upper reservoir during periods of low electrical load and then releases water to a lower reservoir to produce electricity during periods of peak electrical load. Also known as a hydroelectric energy storage plant.
Water energy resources depend on two factors: the height and flow of the river.
The answers are as follows:
1. Japan has a temperate subtropical monsoon climate with abundant rainfall.
2. It is a mountainous island. The island's rivers have great differences, the terrain is high and low, and the water power resources are very rich.
