2007 China will increase its installed capacity of solar energy
In 2005, the world’s installed capacity of new solar cell Digital Camera Battery 1727MW, new solar cell capacity in 2004 compared with an increase of 44.5%, Germany’s new 832MW, Japan’s new 292MW, the United States added 102.2MW. The rapid growth of installed capacity of solar cells, leading to the current mainstream of the polycrystalline silicon solar cell production technology the upper reaches of an increasingly tight supply of polysilicon raw materials, the retail price from 2003 to 30 U.S. dollars / KG about rising to the current 300 U.S. dollars / KG. Polysilicon prices for polysilicon from the solar cell industry, the impact of positive and negative perspectives. There are two negative effects, first, the cost to downstream manufacturers of polysilicon has caused tremendous cost pressures, while capacity utilization allows firms to face less risk. Second, the emergence of a more cost-competitive with alternative technologies to increase the possibility of, the existing poly-silicon technology, an increased risk of being replaced. However, there is also a positive effect, especially for firms in terms of advantages, some advantages of enterprises and polysilicon raw material suppliers have long-term relationship or some degree of vertical integration, the industry does not have the competitive advantage manufacturers Cell chip production capacity and components can become null and void capacity, cells and modules to avoid vicious price competition, rising costs of polysilicon to be passed on to a certain extent, the industry can accelerate the realization of survival of the fittest. On the other hand, in the high polysilicon under the pressure of dominant enterprises will have a strong motivation to cut costs, such as the application of more advanced silicon wafer cutting technology to improve solar cell conversion efficiency and so on, in order to obtain the cost advantages and competitiveness . We can foresee the future polysilicon prices decline, relative to poly-silicon solar technology cost-competitive with other technologies will be further strengthened. Polysilicon solar energy industry, most likely 08-09 years, re-entered the golden period of DSLR Battery Grip, Canon BG-E5 Battery Grip development.
China’s long-term development planning, solar power industry from 2006 to 2020 the compound growth rate of 23.1%. The advantages of photovoltaic solar energy: Resources Unlimited, less polluting, less time and space constraints, safe and reliable, meeting peak energy, energy efficiency in buildings have broad prospects for application is the medium to long term the greatest potential alternative energy sources. The current mainstream power generation cost of photovoltaic solar cell technology is still high when compared with the conventional energy sources, 08 years ago, polysilicon shortage may cause the problem of insufficient capacity utilization would not rule out a breakthrough thin-film batteries, replace the existing multi-crystalline the possibility of silicon technology, but at present there are still thin-film solar cells stable enough, the low conversion rate, as well as short films life constraints, in the commercial applications are still to be developed. Domestic photovoltaic solar cell industry, the relevant listed company, G Tianwei, G aerospace, G CSG, G windsurfing and so on.
A new pattern of energy consumption in China, the new one dollar will be important is the traditional alternative energy sources, as well as between the oil for bio-energy alternative to the traditional oil vehicle. As China’s “rich in coal, oil-poor, less gas” resource endowment characteristics, the future of coal to oil and coal instead of oil as the representative of the coal chemical industry breakthrough will occur. Oil from coal direct liquefaction and indirect liquefaction in two forms, direct liquefaction can produce gasoline and diesel, due to relatively harsh reaction conditions, at present there is no international precedent for successful commercialization. Indirect liquefaction is a first for gasification of coal, by means of catalytic reaction of synthesis produce gasoline and diesel. Coal to oil in the international success stories of South Africa’s Sasol company, the company’s contribution to GDP for South Africa as high as 4% in 2005, the company’s net profit of 15.4 billion U.S. dollars. China and South Africa in the energy endowment has some similarities, that is, less oil-rich coal, coal to oil have a comparative cost advantage. Domestic Shenhua, Yanzhou Coal, Yitai Group, Lu’an Group are engaged in preparatory work for oil from coal, Yanzhou Coal Group in the share reform promised at the appropriate time will allow listed companies Canon BG-E2N Battery Grip to participate in oil from coal project investment. The development of coal-based liquid fuels to solve our oil self-sufficiency is of great strategic significance for the Eleventh Five Year Plan of methanol alternative fuel in the car to open up a new path. In addition to coal-based liquid fuels, bio-gasoline, bio-diesel will also be an important vehicle oil substitute. As of now, “15″ ethanol gasoline specific goals of the plan have been achieved on schedule, the domestic fixed-point four fuel ethanol plants to reach a total production capacity of 1.02 million tons / year, including Heilongjiang China Resources Alcohol Co., Ltd. 100,000 tons / year, Jilin Fuel Ethanol Co., a 30 million ton / year, Henan Tianguan Fuel Ethanol Co., Ltd. 300,000 tons / year, and Anhui BBCA Biochemical Co., Ltd. 320,000 tons / year, these four companies have accumulated more than 120 bio-fuel ethanol million tons, in the Heilongjiang , Jilin, Liaoning, Henan, Anhui, five provinces and Hebei, Shandong, Jiangsu, Hubei, four cities in 27 provinces to be widely used. Eleventh Five-Year Plan reaffirms the bio-gasoline and diesel oil as a vehicle fuel. The recent introduction of a special fund for renewable energy, but also a clear Chenhua Liang-based bio-gasoline and bio-diesel will become a major national special fund to subsidize the object. Biomass energy oils have a clean and green, renewable characteristics, medium and long term alternative fuel in the car, it may be more than coal-based alcohol fuel with more advantages, the future will be used for the transportation of energy an important part. However, the development of biomass energy alternative motor oil the bottleneck is that the cultivated area in China is limited, limited sources of raw materials. At present the relevant listed company, G Fengyuan, G the Great Northern Wilderness, G Gan-based China Resources biochemistry, Arima science and technology, the current domestic related to the profitability of listed companies, and comprehensive utilization of low levels of profitability necessary for the state subsidies.
Experts pointing plug-in hybrid battery technology bottlenecks Canon BG-E3 Battery Grip are still to promote the commercialization
U.S. car maker Cobasys nickel metal hydride rechargeable batteries with A123Systems Inc. to plug-in hybrid “Chevrolet Volt” used in lithium-ion rechargeable battery started the development. Cobasys, Sales Director, Vice President and Chief Systems Engineering Scott O. Lindholm said the A123Systems battery combines the company’s lithium-ion rechargeable battery technology, as well as Cobasys battery in the development of hydrogen accumulated in packaging technology and control technology, the battery system technology .
When talking about plug-in hybrid battery problems are temporary people, Scott O. Lindholm pointed out that the small light-based, and reliability is a major issue, the challenge of Cobasys very large. However, if you do not use lithium-ion rechargeable battery, while the use of nickel-metal hydride rechargeable batteries, then the energy density due to its smaller, with the car when, in order to ensure that the lithium-ion rechargeable battery with the same performance, we need a bigger size and weight of rather difficult.
For the commercialization of plug-in hybrid the time, Scott O. Lindholm, said: “It depends on automobile manufacturers to design vehicles. If equipped with large-capacity battery, can be a long road, but the battery development will take time, so to achieve the practical , but also take some time before. Even a short-term driving the small-capacity battery, but also, as mentioned earlier, there are still a lot of issues. Either battery, practical time to be determined by the automobile Canon BG-E6 Battery Grip, Canon EOS 20D Battery Grip manufacturers. “
