AutoBeta(AutoBeta.net)05/24 Report--

On May 24, the Nanyang Municipal Bureau of Industry and Information Technology responded to the "offline water-hydrogen engine", saying that it was a local reporter who reported the wrong words and that the water-hydrogen engine had not yet been certified for acceptance. Let's review what happened. On the 22nd, Nanyang Daily reported that the Nanyang water-hydrogen engine was offline, which means that the vehicle only needs to add water to drive. In this regard, many experts said that the above-mentioned "water-hydrogen engine invention" violates the law of conservation of energy. Some netizens joked that this is an old scam of "water-to-oil technology", while some netizens questioned, "is this a perpetual motion machine?" Industry experts also believe that there are errors or deviations in the report, suspected of "grandstanding". However, on May 24, the chairman of Youth Automobile Group, a "water-hydrogen engine" research and manufacturing company, responded that the water-hydrogen fuel vehicle technology was mature and would not delay the progress of the Nanyang project, and declared that "the truth is here, not made up."

Pang Qingqing, chairman of Youth Automobile Group, said that the team composed of doctors and doctoral supervisors in the project began to research and develop this technology in 2006. At present, it has not applied for a patent, the technology is confidential, and the R & D cost is confidential. Later, a patent may be applied for, but with the addition of water and material (catalyst), the car can travel 300-500 kilometers. Pang Qingqing said that by making changes to the existing vehicle, it can be changed from an oil-burning car to a "water-burning" car. He plans to start with logistics cars and trucks, and then do buses, SUV and other cars, or even build new cars directly.

It is understood that Youth Automobile Group, headquartered in Jinhua City, Zhejiang Province, is composed of three sub-groups: commercial vehicle Group, passenger car Group and Auto parts Group. It is a private joint-stock automotive industry group, mainly produces NEOPLAN luxury passenger cars, MAN luxury heavy trucks, cars and auto parts. In fact, as early as August 21, 2017, Youth Automobile Chairman Pang Qingqing announced that "the world's first water-hydrogen fuel car will be born in the youth car". According to the official introduction of Youth Automobile, the youth water-hydrogen fuel car does not need to be refueled or recharged. it only adds water and has a range of more than 500km, and the car can reach 1000 km. The working principle of the youth water-hydrogen fuel vehicle is to install a water storage tank on the roof, and the special conversion setting in the car can convert water into hydrogen, input it into hydrogen fuel reaction, generate electricity, and then drive the vehicle motor and engine to make the car run. Pang Qingqing said that the water added to hydrogen-water-fueled vehicles has no water quality requirements and can use tap water, river water and sea water. At the same time, users do not need the cost of hydrogen, but also reduce the storage and transportation of hydrogen. What is a "special conversion device"? youth cars say that the biggest secret of water-hydrogen fuel vehicles is a special catalyst. under the action of this special catalyst, water is converted into hydrogen. However, some people in the industry told reporters that according to the law of conservation of energy, water turns into hydrogen and oxygen, consuming energy, and the role of "catalyst" can only change the chemical reaction rate of the reactants in the chemical reaction without changing the chemical equilibrium.

According to earlier media reports, the water-hydrogen-fueled car that made its debut in 2017 is a youth hydrogen-fueled Manca logistics vehicle. Some people in the media have witnessed that there are two large water storage tanks at the back of the cockpit, which are equipped with two dark blue gas filter bottles. Young cars say that the filtration device can ensure the purity of hydrogen up to 99.99%. After the water storage tank is filled with water, the driver starts the vehicle, drives out of the workshop and returns around the field for a week. In theory, water decomposition can produce hydrogen, but it also needs to consume other energy or rely on electrolytic water to achieve it, Wang Cheng, director of the hydrogen fuel cell laboratory at Tsinghua University, told reporters on May 24, and the efficiency of energy conversion is low. In other words, the so-called "water can drive the car" actually requires energy consumption, this kind of energy consumption is high, the conversion efficiency is low, the cost is high, the actual effect is very poor.

At present, the main means of hydrogen production depends on fossil fuels, but it can not solve the fundamental contradiction between energy and the environment, and high carbon emissions. Hydrogen production by electrolysis of water is sustainable and low pollution, but the technology is not mature, the cost is high and the energy efficiency is low. In addition, some experts said that even if there is a breakthrough in water electrolysis in the future, it is only applicable to hydrogen production, but it will certainly not be realized directly in cars. So the "youth water-hydrogen fuel vehicle" is really a perpetual motion machine. Does this violate the law of conservation of energy? can the car really run thousands of kilometers if it drinks water? With these questions, netizens shouted: chemistry is in vain. What do you think of this?
