Recently, "water hydrogen engine in nanyang off-line" the relevant news caused widespread concern. According to the report, the ministry of industry and information technology said it had not received an application for product access for youngman's "hydrogen-powered vehicle", which has not been announced and cannot be produced, sold or driven on roads. In the meantime, this model also did not declare subsidy of new energy car.
Is water and hydrogen car feasible? Experts say
Public information shows that the so-called "water hydrogen engine" is derived from two patents of hubei university of technology, including "an aluminum alloy for hydrolysis and its preparation method".
Is there such a thing as water, hydrogen or electricity? Hubei university of technology vehicle aluminum alloy hydrolysis hydrogen production technology team leader said to the media interview, as far as the current results, is mature. The person in charge explained that the hydrogen energy vehicle actually does not have the engine, it is carries the hydrogen energy battery in the vehicle, through the hydrogen production material and the device converts the water to the hydrogen, then through the hydrogen fuel reactor to produce the electricity, drives the vehicle electric motor and the engine, thus drives the automobile to run. This whole system should be called "on-board hydrolysis instant hydrogen hydrogen energy vehicle".
This technique is not a precedent. The official website of the ministry of science and Technology released a scientific update on June 29, 2018. According to articles published in the scientific journal Powder Technology, the waste aluminum hydrogen production Technology has been developed in Russia, and the hydrogen generated can be used for fuel cell power generation as vehicle power supply system and fixed small electric devices. A 15-gram can can hold 255 kilojoules of chemical energy, enough to power a 5-liter car for 20 meters.
How practical is this technology? As we have learned, at present domestic about "hydrolysis makes hydrogen" patent is quite much, but apply to new energy car domain really not much. Zhou yi, an assistant researcher at the industrial economy research department of the development research center of the state council, said that according to public reports, youngman's cars produce hydrogen and are driven by synchronous power generation, and there are too many energy conversion links, resulting in efficiency loss, high cost and various purification treatment and reaction control are not easy to grasp.
Zhou yi said that under the premise of strengthening supervision, relevant functional departments should encourage the parallel exploration of multiple technology routes. One is that which technology route will be the first to break through is full of uncertainty; the other is that the applicable scenarios of different technologies are different, such as urban household electric vehicles, fixed-line vehicles and long-distance hybrid vehicles.
Cui dongshu, secretary-general of the national association of automobile manufacturers, believes that the "water and hydrogen engine off-line" in nanyang may involve immature technology, which is exaggerated to some extent. The path of hydrogen production is not disclosed in the news, which is the difficulty in the current commercialization of the industry, and technology development is still needed to solve the cost and other problems.
"I think the focus should be on developing hydrogen passenger cars, not putting hydrogen production on cars." Cui dongshu said that at present, the hydrogen fuel bus is relatively mature, the production scale and the use situation are also fair. Although hydrogen production can be realized in real time through electrolytic water and solar water cracking in the future, the technology is still in the exploration stage and fails to be commercialized due to cost and other factors.
