The first hydrogen car made in China was unveiled, with a range of more than 1000km.
When it comes to buying a car, most of the models available on the market are still driven by traditional gasoline (diesel) or electric power. The rest, such as hydrogen cars, wind cars and water cars, are largely unknown, and not many of them are in mass production, so consumers are naturally ignoring them. However, not too many car companies to produce does not mean that no one production, this is not, one of our domestic brands in the field of hydrogen cars, and its frame is likely to catch up with Toyota, hyundai and other companies have been developing hydrogen cars, who is it? It is wuhan grove hydrogen automobile co., LTD.
Speaking of this grove, I believe many of my friends are not familiar with it. Let's briefly talk about this brand. Grove hydrogen automobile co., LTD., a subsidiary of wuhan institute of geological resources and environmental industry technology (IGE), is named after the inventor of the fuel cell, academician William Robert Grove (invented in 1839). The launch of the grove the hydrogen car project is formally in September 2016, the company from Barcelona team from grove chief design officer and co-founder of Mr Chris leadership, its former fiat and nissan's design department director in Europe, has also help Volkswagen, audi, the company aims to grow up to 2025 annual sales the largest hydrogen fuel cell car enterprise global leader level.
The other is the Fuel cell vehicle (FCEV), which makes hydrogen or hydrogen-containing substances and oxygen in the air pass through the Fuel cell to generate electricity, which then drives the motor, which drives the vehicle. The principle behind such vehicles is to convert the chemical energy of hydrogen into mechanical energy, either through the hydrogen in a combustion engine or by reacting hydrogen with oxygen in a fuel cell to run electric motors. Widespread use of hydrogen to fuel transportation is a key factor in the proposed hydrogen economy.
Why develop hydrogen cars? One of the biggest benefits of using hydrogen as an energy source is that it traps oxygen in the air, produces water vapor, and reduces air pollution from other gas-powered cars. HICEV is generally based on the improvement of internal combustion engine, which is not difficult to achieve. The difficulty lies in how to reduce the cost and achieve safety, and safely solve the problem of hydrogen supply and storage before it can be launched into the market. Hydrogen is already being used in different forms in high-speed vehicles, buses, submarines and rockets.
High pressure hydrogen storage
For one thing, hydrogen has a very low density, and even if the fuel is stored as a liquid in a cryogenic or compressed gas cylinder, there is a very limited amount of energy that can be stored in that space, and hydrogen cars are very limited compared to other cars. Nor should hydrogen escape in large quantities into the atmosphere, which could destroy the ozone layer. Some studies have used special crystals to store hydrogen in a higher density and are safer.
Another approach is to use hydrogen recombinators to extract hydrogen from conventional fuels such as methane, gasoline and ethanol, instead of storing hydrogen molecules. Many environmentalists are not interested in the idea because it relies on fossil fuels. However, it is an efficient recombination process and avoids the difficulties of storing and transporting hydrogen. Fuel cells powered by recombinant petrol or ethanol have virtually no air pollution problems and are more efficient at converting energy than internal combustion engines (which reduce carbon dioxide emissions).
Toyota's hydrogen Mirai
Second, making fuel cells that provide reliable electricity in hydrogen cars is expensive. Scientists are trying to figure out how to make fuel cells as cheap as possible while still being hard enough to withstand the basic problems of impact and vibration. Fuel cell designs are generally fragile and cannot be preserved in those conditions. In addition, many designs require rare materials such as platinum as catalysts, which may contaminate the purity of hydrogen and hinder the supply of hydrogen.
In general, hydrogen has many advantages as an energy source. Hydrogen can be made from water by light decomposition. Hydrogen fuel is a harmless and very clean source of energy. Hydrogen has less loss in storage and transportation than electricity, and its combustion calorific value is high. 1kg of hydrogen combustion produces heat equivalent to 3kg of gasoline or 4.5kg of coke. However, in application, hydrogen storage and transportation, as well as the utilization of solar energy to decompose water for hydrogen production, have always been the bottleneck restricting the development of hydrogen energy. So if grove's hydrogen car can solve all of these problems, it will go down in history as the first and the last, and we'll see how it performs at the Shanghai auto show.
All in all, grove as a little-known new auto brands, in many respects, there is need to open the breach, though the real car for the first model has appeared, but what can properly use hydrogen energy, the future of car users how to easily transport and so on are all need to solve the problem, so for the car, or let us with a look at the attitude to look at.
