Liu Xiaobing detailed solar-thermal power generation commercialization “true way”

Polaris solar PV net news: “the solar thermal power industry in China is ‘ got up early, drove a late set. “National solar thermal industry technological innovation introduced League Secretary General Liu Xiaobing told Xinhua in an exclusive interview with China earlier solar-thermal power project of technical reserves and landing, but have until now been about gaining national real incentives.

He pointed out that, are because see had has many industries past years by walked of industrialization “detours”, in full summary warning Hou, domestic light hot power industry has for future mass commercialization outline out has more clear of “route figure”: construction experiment station, through system process, found supplier; construction demonstration station, established industry chain based, through industry chain; construction scale station, perfect industry chain, reduced power cost; construction commercialization station, achieved no subsidies of competition type development.

Relative advantages

Liu Xiaobing pointed out that current solar-thermal power generation at the initial stage of industrial development, there are still a number of problems to be solved. Main problem is twofold: the first is technical maturity is not high, especially the construction of hydropower systems integration capability is insufficient; second, feed-in tariff pricing mechanism is unclear and incomplete.

However, Liu Xiaobing introduced photovoltaic power generation, thermal energy reserves under perfect conditions, solar-thermal electricity generation through a front-end back-end heat build-up combined with conventional thermoelectric process and deliver 24 hours of continuous power output power quality in this way is far greater than any photovoltaic utilization hours, less than 12 hours the day. In addition, photovoltaic power generation technology in thermal power generation avoid Silicon photoelectric conversion unit, no expensive crystalline silicon material inputs, its decline is far greater than any potential cost of PV.

He said that was more important, solar-thermal power, instead of conventional primary energy consumption potential should not be underestimated. According to statistics, China’s installed capacity of solar thermal power generation potential of about 16000GW, power potential is about 42000TWh/years, equivalent to annual energy output of up to 42 trillion kWh, the numbers 2012 4.9555 trillion kWh in China in terms of total annual electricity consumption, it means that you can replace the current electricity consumption of more than 80%, the potential of other alternative forms of energy can not be compared.

In addition, solar thermal power technology has excellent environmental performance. According to statistics, calculated on a plant’s life cycle, each kilowatt-hour, 900 mg of traditional thermal power plant carbon emissions, gas 435 mg PV 110 mg, wind 17 milligrams, and solar-thermal power generation only 12 mg. Solar-thermal power generation in the whole process of environmental friendliness can be seen.

“Four-step” strategy

Liu Xiaobing said, the future business model of solar-thermal power, through integration of electricity price forming mechanism and mechanisms for technology development, with a focus on integrated development and perfection of power station operation and maintenance techniques and a firm grasp of design technology. Solar-thermal power generation industries is the commercialization of intellectual property objectives to be achieved, and build a complete industrial chain, until the commercialization does not depend on subsidies.

He said, for achieved this a mode, we Union research summary out light hot power industry “four step go” strategy: first step construction experiment station, through system process, found supplier; second step construction demonstration station, established industry chain based, through industry chain; third step construction scale station, perfect industry chain, reduced power cost; fourth step construction commercialization station, achieved no subsidies of competition type development.

Liu Xiaobing said, the current development of solar-thermal power industry in the transition from experiment to model, industry’s main task during this period is the trough, Tower and different technical courses such as Butterfly experiment, not less than 2 for each technology type, this period corresponds to the total scale 700MW of power plant construction. In the process, to cultivate a team of professional power plant EPC team with 10 or so advisable.

He predicted that after 2025, which is to complete the third stage, domestic solar-thermal power level can be reduced to 0.6 Yuan/kWh, with traditional forms of electricity costs, then, the solar-thermal power generation commercialization stages of development before they can be officially opened.

He said that current is approximately of solar-thermal power generation cost 1.38 Yuan/degree/MW unit investment of 29.9 million Yuan. Estimated time of 4 years, until 2018, can reduce the cost price of 1.15 Yuan/degree, which require government subsidy of 3.5 billion yuan for the period. By 2021, generation costs can be decreased to 0.9 Yuan/degree, require government subsidies are expected during this 8 billion yuan. While until around 2025, solar-thermal power installed capacity in China will top 5000MW, electricity cost will be reduced to 0.6 Yuan/kWh. Before and after three phases of the total subsidies of less than 30 billion dollars, will be able to promote solar thermal power generation officially entered the “parity” era.
