From November 28 to December 1, many provinces and cities in China suffered from severe haze. Liaoning, Hebei, Henan, Beijing, Xi'an and other provinces and cities have been greatly affected. For a time, major websites, micro-blogs, and friends' circles were smeared and smeared, and areas affected by smog emerged such as masks being out of stock and air purifiers buying heat.
Western proverbs say that "Rome was not built in one day." Similarly, the formation of severe haze is also the case. At the end of autumn and winter each year, the burning of straw becomes one of the important factors for the formation of haze. Although straw incineration is banned in various regions, the low utilization rate of straw has caused the phenomenon of incineration of straw to continue.
On November 16, the National Development and Reform Commission, the Ministry of Finance, the Ministry of Agriculture, and the Ministry of Environmental Protection jointly issued the "Notice on Further Accelerating the Comprehensive Utilization of Crop Straw and the Prohibition of Burning" (hereinafter referred to as the "Notice"). It pointed out that “further advance the use of straw fuels and raw materials, accelerate the industrialization of comprehensive utilization of straw,†and actively implement the recycling of straw, biogas, and biogas fertilizer, and strive to achieve comprehensive straw utilization rate by 2020. 85% or more; the number of burned fire points or burned areas of straw dropped by 5% compared with 2016." "If the government takes half the energy to develop a pure electric vehicle to solve the problem of straw burning, the situation will never happen today." In an interview, an expert in the automotive industry said so.
The reporter learned that the preparation of biogas from straw and purification into natural gas as fuel is a major way of using straw. Allowing commercial vehicles to "eat" straw may allow it to contribute its own power to improving straw utilization and reducing environmental pollution.
Commercial Vehicle "eat" foreign long straw application <br> <br> use of alternative energy sources in Scania trucks, buses, especially biofuels applications for more than 30 years of experience. He Mochi, Executive Director of Scania China, told reporters: “Staple and other organic wastes are used to make biogas and further purified as natural gas. As a fuel for trucks and buses, Scania has already been used. Scania’s The ultimate goal is to reduce pollutants and carbon emissions, so Scania will promote the use of biofuels, take the initiative to contact biofuel companies and seek cooperation, including China's biofuel companies."
It is understood that Sweden has the world's largest number of heavy vehicles powered by biogas. Commercial vehicles using biogas as a fuel source can meet Euro VI emission standards. Compared with the Euro II emission standard for traditional fuel commercial vehicles, harmful gas emissions can be reduced by more than 95%.
Yao Chunde, deputy director of the China Society of Engineering Thermophysics and director of the China Association of Automotive Engineers, also stated that using straw and other crop residues to make biogas and convert it into commercial vehicle fuel is technically no problem and has many advantages. "Burning straw not only pollutes the environment, but also wastes a lot of organic matter. If straw is made into biogas, it can be used as fertilizer, biogas can be purified as natural gas for commercial vehicles, or biogas can be used to generate power for charging electric vehicles. Both effective use of energy in the straw, and will not pollute the environment, kill two birds with one stone." Yao Chunde told reporters.
Difficulties in the road to industrialization highlighted the "Notice" pointed out that "We must adhere to the basic national policy of resource conservation and environmental protection, and improve the straw storage system in accordance with the principles of government guidance, market operations, and the combination of sparse blocking, and sparse approach." The prohibition of straw burning is a "plugging", and promoting the industrialization of comprehensive utilization of straw is "sparse". There are several important links that need to be dredged in the chain of straw making commercial vehicles.
First, the collection of straw is a big challenge. Different from the large-scale farm system in western countries, China's agriculture has the characteristics of small scale and decentralization. Therefore, the mechanized operations are limited, and straw harvesting and baling equipment are not popular enough. In most cases, after the grain is harvested, the straw is still growing in the soil. If the farmers cut one by one, it will take time and effort. “One more thing, winter wheat is planted soon after the harvest, and the time interval between them is very short. If the straw in the ground is not quickly disposed of, the winter wheat cannot be sown. Therefore, farmers are more willing to burn the straw because it is faster. "Yao Chunde said.
Second, cost investment is another major difficulty. Straw is bulky and requires trucks to transport. Transportation costs are a big cost. The production of biogas using straw fermentation requires the construction of a qualified biogas digester, the laying of biogas transmission lines, the installation of biogas tank temperature control devices, etc., and requires funds. After the biogas is generated, because biogas is a mixture containing multiple gases, it is necessary to purify the fuel for commercial vehicles and special equipment is required. This also requires cost. After purification of biogas, it is also compressed and transported to various gas stations. This process also requires funds. “The utilization rate of straw is very low, and most of it is burned. Because the cost of the whole process of straw collection, transportation, and reprocessing is too high.†Du Fangci, an adviser to the China Association of Automobile Manufacturers, told reporters: “If the harvester is collecting grain At the same time, the straw is also treated, such as baling, compaction, and transportation are also more convenient.This series of measures have been improved, the entire process of industrialization, and finally calculate the price of fuel for commercial vehicles made of straw, and No more expensive than diesel, it can be developed."
Straw fuel have advantages hoped national attention <br> <br> There are many advantages with straw to make fuel for commercial vehicles, many industry experts are hoping to make good use of straw. Yao Chunde told reporters: “I very much hope that the country will support straw for biofuels. This is in line with the circular economy and sustainable development policy.†Yao Chunde said that although there is no emission problem for electric vehicles, China’s power generation depends mainly on coal burning and burning. The more coal, the more carbon oxides are emitted and the more serious the air pollution is. If straw is used to make commercial vehicle fuel, it can reduce excessive dependence on coal. "The comprehensive utilization of straw is as important as electric cars, and the problem of incineration of straw is solved, and the air will certainly improve," Yao Chunde said.
Yang Zaijun, a commercial vehicle industry expert, said that the recycling of used batteries for electric vehicles is still a major problem. It is hoped that the state can use some of its energy and some subsidies to encourage other biofuels. Yang Zaiyu said: "The subsidy policy for new energy vehicles should incorporate other bioenergy into the subsidy range. Biogas produced from straw also belongs to new energy and should be given incentives and subsidies."
Wang Jia, a wholly-owned subsidiary of Shaanxi Auto and a general manager of Xi'an Lande New Energy Automotive Technology Development Co., Ltd., said that the single-minded encouragement of new energy vehicles as an incentive for electric vehicles will virtually obstruct the development of alternative energy sources. From a market perspective, as long as enterprises use fuel for energy conservation and emission reduction, they should enjoy state subsidies. This will not only be conducive to the development of alternative energy sources, but also conducive to environmental protection. If the country encourages the production of natural gas from straw, Shaanxi Automobile will actively adopt such biofuels. Wang Jia said: "For a commercial vehicle company, whether it is traditional petrochemical natural gas or natural gas that is made from straw and then purified, it can be used as fuel if it meets vehicle standards."
