According to China’s “long-term renewable energy development plan”, China’s annual amount of solar energy resources can be developed up to 1.7 trillion tons of standard coal equivalent, and include wind, hydro, biomass, geothermal energy, including renewable energy equivalent to all other standards Less than 6 billion tons of coal. Accordingly, experts predict that solar energy will gradually become the dominant global energy. Solar energy development at this stage include solar thermal and photovoltaic camps, from a realistic combination of factors to consider, slightly obvious advantages of solar thermal, solar thermal technology at the same time as the rapid improvement and force the rapid growth of companies such as Norit, solar thermal and photovoltaic power generation will also be the advantage of salon competition.
At present, photovoltaic field all to grasp core technology in the developed countries. B154SW01In which European governments to preferential policies to support enterprises to develop solar photovoltaic industry, are also ways to use subsidies to encourage people to use solar energy. “But the reasons known to all, European countries do not produce polysilicon in their own countries, but rather the production of polysilicon into the developing countries,” Han Tianen said, “Polysilicon production is an energy-consuming process, to produce carbon dioxide, which a carbon emissions problem, if developed countries want developing countries to buy the raw materials the production of solar silicon, we must follow to purchase the carbon emissions produced by developing countries to use the money to solve the technical problems of pollution links. “In addition to Beyond this, the cost of photovoltaic power generation is still 10 times the thermal power, photovoltaic power generation cost has hindered the pace of development.
And core technology and raw materials out of the country, the production process of high energy, high cost of photovoltaic power generation than solar thermal power generation “has a core technology, production materials, glass and steel main needs” advantage. The high temperature strength Norit collector product has entered the fast production, promotion stage, in refrigeration, industrial preheating and power generation, the application field and laid a solid foundation.
“Compared to photovoltaic, solar thermal power generation is more convenient and domestic power grid in docking, because the basic principles of solar thermal power and thermal power of the principle of similarity, while the domestic power network construction mainly thermal-based. As is the use of polycrystalline silicon photovoltaic cells convert light into other energy carriers, so the traditional test of a great power to regulate and control. “investment consultant in the energy industry, said chief researcher Jiang Qian, solar thermal power will not power peaking, wrong peak of a great burden, that is its absolute advantage.
Solar thermal power followed the larger the lower the cost of the law. Currently, the industry generally accepted scale is 1000 MW, the scale of 1,000 MW of solar thermal power plants can reduce the cost of electricity to the considerable advantages of 0.7-0.8 yuan per kWh. “Solar thermal power generation of the technical issues have been resolved, but the initial investment is very large, like the 1,000-megawatt-scale needs 20 billion of upfront investment, which is unbearable for some businesses, this area also needs the support of national policy.” Reaffirming that the civilizational says.
Solar Thermal for direct radiation in 1900 kilowatts hours per year / square meters, and the resource conditions of the world only the United States, Spain, Africa and China have. The United States and Spain have been the winner, while in China, solar thermal power generation project has just started, there are large areas of light and heat resources, waiting for development. This is behind it, is undoubtedly a huge amount of the market.
According to the European Solar Thermal Association, published in 2005, a report is expected in the next 20 years, the global solar thermal power generation will be 16.4 billion euros a year’s huge market. By 2025, the world’s total installed solar thermal power generation capacity will reach 36,000 megawatts; to 2040, solar thermal power generation to meet the 5% of world electricity demand. Relative to the global market, its domestic market potential for solar thermal power generation is very large. It is engaged in electric light and heat of the Chinese Academy of Sciences researcher Ma Sheng Hung is estimated that by 2015, solar thermal power generation in China will reach 400-500 MW. After 2015, annual solar thermal power installed capacity will reach 300-500 MW.
“Photovoltaic and solar thermal power, advantages and disadvantages of each, who will replace who I do not think the future is the coexistence of two more, have their own applications.” Jiang Qian said that the relatively large-scale solar thermal power generation, while the PV is relatively small, suitable for families, residential area and so, therefore, the two are not exactly the same application. But speaking from the energy and technology side, light and heat more in line with China’s national conditions and long-term planning stage.
The current global use of solar heat into electricity installed capacity of about 700 MW, 1,200 MW of projects under construction, has announced the construction of the installed capacity was 12,600 MW, and these figures are updated weekly. View the current form of development, the rising star power in the field is likely to surpass PV in the near future, become an important force in the area of power generation.
However, the rapid development of solar light and heat, can not do without the constant efforts of domestic solar energy companies. “Power Norit as a leader in the solar industry, independent research and development has always insisted, advocated by continuous technical research, make full use of solar thermal technology in the areas of life, and to further advance the industry. Do the same development, and fully enter the power generation only a matter of time. “New Energy Co., Ltd. Shandong Power Norit reaffirming that the civilizational, said general manager.
