Recently, domestically discussed shale gas, and even some people believe that the shale gas revolution or reduce the urgency of the development of new energy vehicles. Of course, some people hold different views.
In fact, shale gas is a kind of natural gas. Generally natural gas is mainly oilfield gas, gas field gas, coalbed methane, mud volcano gas and biogenic gas, and shale gas is extracted from shale layer. Shale gas reserves are huge all over the world. What's more important is that the two largest energy consumers in the United States and China have proven reserves of shale gas in the top two in the world and can be used for more than 200 years. .
Recently, Zhang Guobao, deputy director of the Economic Committee of the National Committee of the Chinese People's Political Consultative Conference and director of the Expert Consultation Committee of the National Energy Commission, pointed out: "The massive exploitation of shale gas in the United States has reduced the dependence of the United States on foreign oil and gas, and the U.S. energy independence policy has achieved remarkable results. Reliance reduction has had a subtle impact on US foreign policy. China also has abundant shale gas resources, but its burial conditions are more complex than in the United States. The recently announced shale gas development plan will reach 6.5 billion cubic meters in 2015. The difficulties are not small. It takes a long time to form a production capacity like the United States."
After decades of development, shale gas in the United States produced the first shale gas well in 1981. It took 15 years for the shale gas exploitation to reach 12.2 billion cubic meters. After nearly 30 years. The development of shale gas in China is still at an exploratory stage and the technology is not yet mature. The development of shale gas requires a lot of investment in technology and capital. Domestic oil companies have not yet demonstrated their enthusiasm for shale gas development, and even tendering is not active. participate. In addition, the lack of water resources in the western region is also an important constraint.
On the other hand, the U.S. practice is to replace coal with shale gas. According to the statistics of the US Department of Energy, in the past year, US coal-fired power generation decreased by 19%, while gas-fired power generation increased by 38%. Gas-fired power plants emit only half as much carbon dioxide as coal-fired power plants, which has reduced energy-related CO2 emissions in the United States by 450 million tons over the past five years. The fatal flaw of China's primary energy structure is that the proportion of coal is too high, exceeding 70%, and the proportion of oil and gas is only 18.6% and 1.7% respectively. The ratio of oil, coal and gas in the United States is 38.6:22.8:27.0. The proportion of British gas is close to 40%, while the proportion of coal is only 15%. Therefore, the focus of China's energy policy is to reduce the proportion of coal burning, and one of the measures is to develop nuclear power. If shale gas development progresses, the first is to replace coal to generate electricity, in order to reduce carbon dioxide emissions, for cars is secondary.
According to statistics from the China Automotive Industry Association, in the first half of 2012, automobile manufacturers produced 3,167 new energy vehicles and sold 3,525 new energy vehicles, including 3,444 pure electric vehicles and 81 plug-in hybrid vehicles. The progress of new energy vehicles is not smooth, and some people even think that they should give up electric vehicles. It is difficult for electric vehicles to form a large-scale market in the near future because battery technology does not break through, but its direction of development cannot be abandoned, and it should continue to be explored. As Chen Guangzu, a senior expert in the automotive industry, pointed out: “The starting point of energy vehicle planning is more focused on emission reduction. The ultimate solution to the plan is to solve the greenhouse effect caused by vehicle emissions.â€
We must also note that in the same period, the production and sales of unplugged hybrid vehicles were 3,807 and 3,905 respectively, and the production and sales of alternative fuel vehicles were 21,100 and 21,700, respectively. This shows that the market for hybrid and alternative fuel vehicles is beginning to take shape and we should give it enough attention.
The most important thing now is that the development of new energy vehicles cannot be of double-mindedness. If you now abandon the development of new energy vehicles and the shale gas does not know when the revolution will be successful, the automobile industry will be caught in a dilemma, and you will have to waste it for many years.
