2050 renewable energy is expected to dominate the power system

Polaris solar PV net news: December 16, China and Denmark renewable energy development project issued the China renewable energy roadmap 2050 report, renewable energy for 2020, 2030 and 2050 domestic high-growth scenario, 2050 years wind power, solar power is expected to dominate the power system.

Associate Director, Danish renewable energy development project introduced Wang Zhongying, Executive Director, in accordance with the study design scenario, total final energy consumption by more than 60% of electricity, electricity supply reached 91% per cent of development of non-fossil energy sources, renewable energy accounted for more than 86%. If the above goals are met, China’s sulfur dioxide emissions of various pollutants, nitrogen oxides, heavy metals will be lower than 1980 levels of emissions.

In terms of wind power development plan, according to the project, basic scenarios in 2020 wind power installed capacity is expected 200 million-kilowatt, 400 million-kilowatt 2030, 2050 1 billion-kilowatt; in a positive scenario in 2020 wind power installed capacity is expected 300 million-kilowatt, 1.2 billion-kilowatt 2030, 2050, 2 billion-kilowatt.

Report concludes that wind energy resource potential above 3 billion-kilowatt, under the existing conditions of wind turbine technology, more than enough to support 2 billion-kilowatt wind power installed capacity. By 2050, the basic scenario, the total wind power investment of 12 trillion yuan (2010 prices); in a positive scenario, total wind power investment to 24.5 trillion yuan (2010 prices).

On route to development, by 2020, positive and orderly development of onshore wind power, offshore wind demonstration; 2021-2030 land, offshore wind energy and development, and offshore wind power demonstration in 2031-2050, in Eastern, Central and Western onshore wind power and offshore wind development.

National renewable energy Center Vice Director of Hu Gao said: “in General, our nation’s wind energy resources adequate to support our goal of large-scale wind energy development. Countries are also planning nine qianwanqianwa-level wind power levels, layouts in the North and coastal areas. We examined seven bases each time economy and concluded that the seven bases of economic exploitation amount can be more than 1 billion-kilowatt. ”

In terms of solar energy development plan, the basic scenario projected 2020 PV 100 million-kilowatt, 400 million-kilowatt 2030, 2050 1 billion-kilowatt; in the positive scenario is expected 2020 PV 200 million-kilowatt, 800 million-kilowatt 2030, 2050, 2 billion-kilowatt.

Research report finds that the short and medium term commercial module efficiency of crystalline silicon cells over 20%, dominant market position. 2030 thin-film battery technology breakthrough efficiencies close to crystalline silicon cells, in equal shares with crystalline silicon cells on the market. 2025 solar PV to achieve parity. After 2030, the solar power will become one of the leading alternative energy after 2050 solar power will become one of the dominant power.

Photovoltaic power generation, distributed PV market will be gradually expanded, hydropower development will in the short and medium term and ground flat term distributed PV architectural resources saturation tends to market stability. Centralized PV power station due to plenty of desert resources, network-building and absorptive capacity of strengthened and more with strong development potential.

In addition, the project team focused on developing biomass energy (residues and wastes as raw materials). At present, the utilization of biomass energy in China is only 10%. In accordance with the roadmap, biomass energy resource in the future is expected to reach about 600 million tons of standard coal, biomass energy industry in 2050 will provide more than 300 million tons of standard coal products as substitutes for fossil energy, stimulating investment of 1.56 trillion dollars.

At present, the development of renewable energy is already the country’s strategic choices. The energy development strategies action plan recently issued by the State Council (2014-2020) calls for “green carbon” development strategy 2020 non-fossil fuels in primary energy consumption reached 15%, raise the proportion of non-fossil energy in 2030 to about 20%.

New Energy Department Shi Lishan, Deputy Director of the National Energy Council presented at the project presentation, the renewable energy is developing rapidly in recent years, increased scale of wind power and photovoltaic power generation. But with Denmark over China’s energy supply relies mainly on coal, non-hydro renewable energy’s share of energy consumption is low. In addition, renewable energy-rich regions in the North, on the one hand a lot of burning coal, on the other hand many clean electricity can not be grid-connected.

“In the development of clean energy, we are not thinking of technical problems, and more should be of interest. We have not built up power management system adapted to renewable energy, not build priority renewable energy concepts and awareness. “Shi Lishan said.
