Optical–Future Dominant Energy
December 30th, 2009In a recent announcement by the National Expert Advisory Committee on the energy (known as the Energy Committee of Experts), a solar symposium, attending dozens of experts generally agreed that low-emission of carbon and the main trends in new energy sources, the world economic revolution, the lens most likely to become China’s next most important one of the largest share of energy sources.
“But now, in China’s solar industry is still political, technical and market, as well as many other obstacles to development exists.” Integrated National Energy Bureau, Deputy Director, National Energy Advisory Committee of the Expert Group the Secretary-General Huang Shi-Qiang said, “out of the development of to eliminate bottlenecks will receive solar energy industry, more than a bright future. ”
In the “case” to “solar thermal” sudden emergence of solar energy
Solar photovoltaic and solar energy, including the two parts of thermal power generation. According to experts, in recent years, photovoltaic and solar thermal power plant in Dell Latitude D510 battery, Dell Latitude D520 battery, Dell Latitude D600 battery China, one generation after another has been unprecedented attention in China’s solar energy is becoming an important force in renewable energy.
On the status of the development of PV industry in China, energy expert committee to invite experts, CLP Technology Group, No. 48, Wang Jun, deputy director of North Korea, the Institute said, “China’s photovoltaic industry, the formation of a great chain of industrial scale.”
For example, North Korea, said Wang Jun, for example, industrial production in China is the world’s silicon, high-purity silicon production of 1,000 tons, and now the technology has been basically ruling class wafer-scale processing and has a world-class level to a lower price to the cell and productivity, and the first time in the world order, silicon materials, components significantly reduced the output of manufacturing solar photovoltaic power generation, China’s cost of photovoltaic power generation technology has matured.
Trend analysis of national photovoltaic industry, Wang Jun, on the view that, first, the overall technological level in China’s PV industry to improve and the rapid development of photovoltaic power generation industry equipment manufacturing industry, China’s photovoltaic power generation, business development costs will be less much more investment, as well as other international markets, competition, foreign-invested enterprises have also entered the Chinese PV market, quietly, China has become the world’s largest photovoltaic system in the global market. That is the problem, China will enter the golden age of photovoltaic power generation industry.
“Our solar thermal development of the industry is also very fast.” Energy experts invited by the Commission of Experts, the National 973 Project Group, the solar photovoltaic system, right, director of Key Laboratory of Chinese Academy of Sciences with the Chi-Feng told reporters. Wang of every description, “15″ period, the Chinese Academy of electrical engineering thermal physics, and other research institutions and yellow millet ah Solar Energy Group Co., Ltd. Xinjiang New Energy Company, Nanjing Chunhui Science and Technology Industrial Co., Ltd. and Chinese Academy of Sciences Institute of other companies, research project has begun to solar thermal power generation technologies. He said: “At the same time, our scientists have disc-type power generation system, tower and power generation systems of cells through the Center to learn and master as a mirror reflectivity of solar thermal power generation, the core technical standards, high precision, high-precision dual-axis tracking control system , high-calorie density, thermal, solar thermal energy conversion. ”
In the “Eleventh Five-Year”, as the country attaches great importance to renewable energy support of government departments, solar thermal power generation. Wang Feng said, “Economic Information Daily” reporter, the country’s R & thermal power generation in optical technology, D is ready for use. From 2006 to 2010, in the capital photovoltaic science and technology in a multi-4750 Dian ○ million, photovoltaic power generation in technology developments.
It is reported that Chinese scientists have created a solar thermal power generation key technologies. For example, high-tech precision on heliostats wind loads, tower high-temperature heating the heat sink technology, storage technology, the station’s power control technology, system design and integration technology generation of the building, manufacturing processes and integration to achieve, through the condenser vacuum-tube technology.
“In the light and heat and power generation, China has formed from the basic materials, host and system integration design chain.” Wang’s every proud to say that from 2007 to date, China has three years of the “Solar thermal technology Sanya International Forum on three consecutive years, the Forum has become the solar thermal power one of the most important meeting. three of the world’s largest solar thermal company, the International Energy Agency and the U.S. Department of Energy of the Soviet Union, he began to send representatives to attend the meeting.
Dial “cloud” can only see the “Solar Day”, still faces many challenges
“As the world’s solar energy resources, China’s solar energy is undoubtedly the most eye-catching sun. Industry,” Energy, Electrical Engineering, Chinese Academy of Sciences Institute Xu-hua, deputy director of the Institute nominated by the experts say: “However, we must recognize that, due to “Sunshine” have “cool in the industrial development of solar energy in China is still” faces many challenges. ”
With regard to solar energy industry in China’s development, Xu said that China, for example: for example, the lack of clarity and solar thermal industry development plan, yet to be established in the public sector research and testing and certification platform, throughout the solar photovoltaic power generation system industrial chain, to form a complete hardware and software, people should continue to improve skills and enhance the photovoltaic power generation rate and the approval process the approval procedures are not clear network and large-scale promotion there is great resistance, lack of technical standards and management protocols, especially electricity, department because of security concerns, power quality and management issues, as soon as possible technical standards and management standards, there is a power of PV power plant maintenance and management of the issue of independent, professional and technical personnel in order to post far behind.
“Although the Chinese solar energy in various fields of technology, made some new progress, but it is not strong capability of independent innovation is still limited, the rapid development of industry, the biggest bottleneck.” XU Hong-wah, said: “Our lack of scientific research and technological accumulation yet the establishment of sustainable Dell Latitude D610 battery, Dell Latitude D620 batterydevelopment system, the industrialization of basic research, key technology and equipment to support the industry. Solar Energy China’s independent innovation capability and power generation capacity for sustainable development compared with developed countries still lag far behind. ”
For many of the media in reporting on China’s polysilicon materials, the problem of surplus production capacity, Xu researchers presented their own unique point of view. He believes that China’s current polysilicon production can not meet the internal needs of the industry chain, the actual production capacity currently under construction is not to say that there is a surplus. He told the “Economic Information Daily” Reporter: “production costs are high, product performance is poor, limiting the development of photovoltaic industry, the biggest obstacle. The industrial expansion in order to match lower prices of raw materials, taking full control of advanced technology , product performance to achieve the same level of international, so it can significantly reduce the cost and promote the rapid development of solar power industry. ”
Solar cell depletion and pollution problems, is considered in the development process in an industry worthy of attention outside the industry. XU Hong-hua said that in the production of a single crystalline silicon solar cell company in the production process, the unit energy consumption is relatively high, but if the account is not the case. In the crystalline silicon solar cells, produced from the sand at about 2.65 unit of electrical energy consumption of the system, even if the annual production of 10G Waxy photovoltaic systems, energy consumption accounted for only 265 thousand degrees in 2007, the ability to install the State 0.8%, 5% of the total power consumption of aluminum and steel accounted for 14% of the total electricity generation, energy consumption is not high. As the polysilicon and solar cell technology, this indicator will be further reduced, photovoltaic power generation is a high-energy consumption industries, a level, a high-consumption of power plants, industrial purposes and should not be regarded as a high capacity consumer-oriented industries .
“In the industry, photovoltaic power generation, metallurgical silicon production on the environmental impact is not large, while the polysilicon production process, although there are some waste, producing a large number of emissions, waste is mainly silicon tetrachloride and trichlorosilane liquid and so on, the main is a hydrogen chloride gas. “XU Hong-hua said,” Economic Information Daily “,” for these wastes, whether it is with the recycling, or free of pollution problem is not technology, but also can serve as a recovery of other chemical industrial raw materials. polysilicon plant has already begun to see through the exhaust gas recycling to the production, pollution treatment, recycling and make full use of the material, which can be zero-emissions and clean production.
From the “alternative” to “light-emitting diodes” China still has a long way to go photoelectric
The strategic position of the Chinese solar energy “is becoming more and more important.” XU Hong-hua believes that complementary and alternative energy sources from the existing resources and gradual transition in the future to become a leading solar energy and energy origin. He said: “Solar energy to solve our energy problem and effective solutions.”
According to Xu Hong-hua is expected in theDell Latitude D800 battery, Dell Latitude D810 battery, Dell Latitude D820 battery future solar energy, especially in 2030, will be a large-scale applications; the 2005 years later, in all forms of solar power are more likely to become the main source of energy.
Energy Expert Committee invites experts, Sun Yat-sen Institute for Solar Energy Systems, said Dr. Shen-hui, the scientific concept of development, the energy payback period, and another point of view, the future of photovoltaic power generation is the most promising technology for solar power generation .
“Based on these three renewable energy technologies, China’s actual situation, the relative wind, biomass, solar energy, the most development potential, including solar photovoltaic power generation potential is enormous.” Shen Hui said: “You can pull cars photovoltaic industry, machinery manufacturing industry, construction industry is the largest future economic growth. ”
Shen, photovoltaic industry in China’s development, through, 5-hui, six years of competition in the industry to realize leap-forward development, amazing world, the government should support it.
In China, the biggest potential market for solar energy? XU Hong-hua believes that with the resources and cost considerations, the most promising photovoltaic power generation is the “Desert of the nuclear power plant. He said:” From the resource perspective, the Western Desert region is the region’s most abundant solar energy resources, 2 land cost, the most expensive power plants desert, and the three areas, said the construction market in the western region of several megawatts and 10 megawatts of energy from the desert plants, issued by the local consumption of electricity, basically. ”
Experts believe that solar energy will become a “leader”, there is still a long way to go. First of all, to announce a new energy to revitalize the planning, the second, solar photovoltaic and solar thermal electricity needs as early as possible. Third, to strengthen scientific research, establishment of an independent intellectual property rights, sustainable development, solar power industry system.
“Although the solar photovoltaic industry and the rapid development of China’s thermal power, but the overall phase of the seedlings Kawashima.” Jun Wang Chao, the researchers said, solar energy industry in China is a country full of light industry, the need for big government and social concerns and stronger, so that China’s renewable energy future a major force in support.
