Polaris solar PV net news: Reporter: “China-Denmark renewable energy development project” to an end, the most important achievement of the Chinese wind energy, solar energy, biomass energy development road map, recently released, please describe them.
Hu Gao: study roadmap is “Danish renewable energy development project” very important outputs, we in Denmark supported by experts, inviting the participation of many local and foreign institutions, and related research work has also been United States energy Foundation supports. The roadmap includes 3 parts: wind power, solar power and biomass energy. We hope that this report the research work can be sustainable in the long term, as the International Energy Agency’s Energy Outlook reports regularly updated, to reflect the status of emerging technology, reference to relevant government departments and industry.
Reporter: could you talk specifically about wind energy route map?
Hu Gao: wind turbine of the roadmap by the Energy Research Institute, national development and Reform Commission, jointly with the International Energy Agency such as water regulation, China Wind Energy Association, national relevant bodies, published for the first time in 2011, 2014 was updated.
Overall, our nation’s wind energy resources adequate to support the development of large-scale wind energy. Large-scale wind power-wind resource data, combined with the cost analysis of the supply curve, initially proposed wind power development in China’s medium-and long-term goals.
Research results is divided into two a scene considered: in basic scene zhixia, 2050 years wind electric capacity can reached 1 billion-kilowatt around of scale, from currently domestic related of energy research results view, basic identity in 2050 before and after, wind electric should reached 8~10 billion kW of volume level, and provides trillion kWh above power of development target; we also proposed has a more optimistic of active scene, that to 2050, towards in basic scene of based Shang doubled.
Reporter: If you want to achieve such a high proportion of wind power development is necessarily required in terms of the entire power system operation to do quite a lot of changes.
Hu Gao: Yes, wind turbine development requires effective integration of wind power into existing power systems, also need to be adapted to the power system of wind power this volatility changed accordingly. Like, reference Denmark of high proportions development experience, needs further advance power market run mechanism and run management way of change, mining and release power system of flexibility; developed and implementation wind electric grading, and local across provinces elimination na programme, coordination wind electric, and other power and grid construction, and load management,; in can renewable energy share high of local regional, established can renewable energy power of smart grid system. After 2030, complete the building of electricity market operation and management mechanism adapted to new energy sources, energy storage, smart grid and other advanced technology widely used in electric power system, fundamentally the incorporation of wind power and eliminate the problem.
Reporter: could you tell us something about our solar roadmap?
Hu Gao: more widely-distributed solar energy resources, use more convenient. Judging from the global energy transition strategies, have argued that solar power over the next few years, through technological innovation, large-scale development, electric power system, as well as other supporting technological progress, will supplement energy, from the current areas of alternative sources of energy, in the future and gradually developed into China’s “independence, self-reliance, low-carbon, sustainable” energy system is one of the main energy.
Roadmap for study of combination of Chinese renewable energy society, Institute of electrical and other institutions and industry experts. Report on proposed solar-specific development goals.
In the basic scenario, solar photovoltaic power generation in 2050 close to 1 billion-kilowatt the size of thermal power generation reached million kW size, low-temperature heat utilization in widespread use.
And wind power, the road map also made a more optimistic vision for solar, in a positive scenario, the objectives set out in the road map is that based scene to compete for the use of solar energy will double by 2050 solar power generation, heating together contributed more than 800 million tons of coal equivalent in the field of alternative energy.
Solar technology a lot, these technical routes exist between competing, alternative relationships with each other, so the road map does not attempt to define a variety of future developments, but in the production scale, efficiency and cost trend analyses based on should work toward greater emphasis on the technology and applications, as well as the appropriate incentives and safeguards. In addition, also pointed out that the national energy planning, energy management, energy use patterns and other aspects, giving priority to the development of solar energy is adjusted accordingly.
Reporter: how biomass will have a development?
Hu Gao: biomass energy than solar energy technology to multifarious, participate in road maps also include the national development and Reform Commission’s Energy Research Institute, Tsinghua University, the Chinese Academy of Sciences Guangzhou energy, Department of agriculture planning and design Research Institute, environmental protection bodies such as the Institute of light industry. Currently available biomass resources in China is about 300 million tons of standard coal, but only using about 10% the whole biomass has great potential in China.
Current low levels of biomass energy development in our country, all kinds of technical development imbalances, market mechanisms and incentives system is not yet complete, total use is small. Thus, by 2030, biomass energy industry mainly in the relatively more mature generation, heating and bio-gas main; after 2030, bio-liquid fuel will enter a period of rapid development, increases of raw materials essential for the production of bio-liquid fuel demand. Analysis of comprehensive factors such as resources, technology and market capacity, research suggests that by 2050, total biomass energy can replace fossil fuels will exceed 300 million tons of standard coal, which is quite large for supply.
The overall pattern of future development of biomass energy should be “Government guidance and market operation”. Government based on a clear direction and size of the industry, by opening up markets, removing market barriers and develop aspects of market operation rules, strengthen market supervision, speed up the development and utilization of biomass energy.
Reporter: will the goals set out in the road map and how relationships between Governments planning objective is?
Hu Gao: study on the roadmap, is the relevant research institutions and industry, combined with the current national energy development strategy and the development of renewable energy technologies, industrial capacities, market demand and other factors in an academic way, also to the future development of the technology, policies supporting puts some expected path. We hope that this study, for relevant departments to develop planning, industrial policy to provide some valuable information.
