Before it was the coldest time, some of the shortcomings of electric vehicles had been exposed.
The winter endurance is seriously attenuated, and the nominal endurance is directly cut, resulting in many electric vehicle owners who dare not turn on the air conditioner when driving, preferring to be frozen in the car. The charging time has increased significantly, and some car owners who do not have private piles even start to grab parking spaces at 4 a.m. So in addition to electric vehicles, do future new energy vehicles have other answers? It is clear that hydrogen fuel vehicles have greater potential for development.
Compared with traditional cars, hydrogen energy vehicles use hydrogen as a power source, energy conversion efficiency is high, there is no pollution at all, and hydrogen can be produced from water, which is inexhaustible and can get rid of foreign oil dependence in one fell swoop.
Compared with pure electric models, hydrogen energy vehicles have a short charging time, 3-5 minutes can be completed, less affected by temperature and speed, like electric vehicles in winter to become electric daddy situations, will no longer exist.
However, there are also many problems in the popularity of hydrogen fuel vehicles, such as the construction of hydrogen refueling stations, and the high cost of hydrogen production. However, recently, the cost of hydrogen production has declined to a certain extent, and the technology of low-cost hydrogen production has made a breakthrough.
Previously, China's hydrogen production methods were mostly coal hydrogen production and electrolysis of water to hydrogen. Domestic coal resources are abundant, so coal hydrogen production is the more mainstream hydrogen production method before, and the cost is about 9-14 yuan / kg. In terms of photovoltaic hydrogen production, electrolysis of 1 standard cubic meter of hydrogen requires about 4.5 to 5 kWh of electricity, which is more expensive. It is precisely because of this that the production cost of hydrogen has been high. However, recently, the technology of photovoltaic hydrogen production has made a breakthrough, using renewable energy such as photovoltaics to directly prepare hydrogen, the cost of which can reach 0.83 yuan / Nm3, corresponding to the lowest unit quality cost of about 9.30 yuan / kg.
Take Toyota's hydrogen fuel vehicle MIRAI as an example, its hydrogen reserves are about 5.6 kg, the endurance is 850 km, calculated down, if calculated according to the lowest cost of hydrogen production, only need the cost of hydrogen of about 52 yuan, you can live 850 km, if only the cost of hydrogen production, the cost per kilometer is about 6 cents. Of course, the final price of hydrogen at the consumer end is not only the cost of hydrogen production, but also the construction of hydrogen refueling stations, the transportation and storage of hydrogen, etc., all of which must be included in the cost of hydrogen. But at least the cost of producing hydrogen is no longer as unattainable as before.
Many people wonder why they should use photovoltaic power generation and then use electricity to produce hydrogen, is this not a superfluous move? Among them, this is just like in the trough period of electricity consumption, the water downstream of the reservoir is pumped upstream, the trough period of electric energy has a surplus, and this part of the electrical energy is difficult to store, and used to produce hydrogen, the energy is stored in the form of gaseous fuel, so that hydrogen energy and electric energy can be converted into each other, complementary advantages.
On December 3, the Ministry of Industry and Information Technology issued the "14th Five-Year Plan for Industrial Green Development" to accelerate hydrogen energy technology innovation and infrastructure construction, during the upcoming 2022 Beijing Winter Olympics, Zhangjiakou Will Invest a Total of 625 Hydrogen Fuel Vehicles, Shanghai and Guangzhou, have introduced subsidy policies for hydrogen fuel vehicles, hydrogen energy society seems to be out of reach, but countries dare not relax, because who walks in front, who may completely get rid of dependence on oil resources, a new era of hydrogen energy, It's coming slowly towards us.
