Multi energy complementary new energy and traditional energy will develop in an inclusive way
In recent years, the development of clean and low-carbon energy is one of the main directions of China 's energy structure reform. At the 2019 Taiyuan energy low carbon development forum "new energy development bottleneck discussion" sub forum held recently, Zeng Shaojun, professional vice president and Secretary General of new energy chamber of Commerce of all China Federation of industry and commerce, believed that in recent years, China has undergone tremendous changes in wind, solar energy, biomass energy, thermal energy and other aspects, showing that the "wind" has passed, the "sun" has risen "Living" is full of vitality and "hot" gas. He pointed out that in the future, new energy will develop in a distributed way and become inclusive together with traditional energy. Therefore, it is necessary to continuously innovate key technologies, do a good job in coal subtraction, green addition and energy efficiency multiplication, and realize multi energy complementarity.
Prason Agarwal, regional project director of the International Renewable Energy Agency, said that to accelerate the development of renewable energy, comprehensive technologies should be developed, such as identifying and confirming the location of renewable energy, developing financing projects, reducing industrial energy consumption, adding new energy vehicles, deploying digital communication technology, etc.
New energy takes "expanding market and reducing cost" as policy
Zeng Shaojun pointed out that China's energy revolution has three paths: reduction revolution, increment revolution and efficiency revolution. The energy reduction revolution includes three aspects: subject, means and object. However, the reduction revolution is not "one size fits all", simple and absolute reduction, but "structural weight loss". The control of the total amount of energy should be careful with administrative constraints. Energy incremental revolution includes traditional energy, new energy and overseas energy. Traditional energy development should be based on "structural adjustment and environmental protection". Efforts should be made in green mining, clean use and efficiency improvement. New energy should be based on the principle of "expanding market and reducing cost". The energy efficiency revolution includes the energy network and market system. The energy network is mainly to speed up the construction of smart grid and strengthen the power demand side management. The interconnection with surrounding countries and regions should be considered. The oil and gas network should be improved to form a large system of national interconnection. The expansion of the west east power transmission capacity and the UHV transmission should be on the agenda. In the aspect of market system, we should open up market access and introduce competition; reform the way of energy management by the government, speed up price reform, distribute interests reasonably and mobilize the enthusiasm of all parties.
Zeng Shaojun believed that at present, in terms of China's new energy, first, the "wind" has passed. China's wind power industry has undergone great changes in more than ten years. It has experienced a tortuous process of explosive high-speed development, falling to a low point and then turning to recovery. At present, it is in a period of steady development.
Second, "Yang" light rises. China's solar energy heat utilization industry has developed rapidly, and has become the world's largest country in solar energy heat utilization production and application. The industry has experienced a rapid growth period, and is now transitioning to a mature period of calm development.
Third, "life" is full of vitality. As an important part of China's future green energy, biomass energy industry is showing great vitality. Facing the dual pressure of energy shortage and environmental pollution, biomass energy as a clean, environmental and renewable energy is a very ideal alternative. Even in the context of weak global economic recovery, the development of China's biomass industry has made breakthrough progress.
The fourth is the "hot" air. China is rich in geothermal resources. Due to the technical difficulties, investment instability and other risk factors in the process of development and utilization, the utilization of geothermal resources in China is still relatively limited, accounting for less than 0.5% of the energy structure. However, from the perspective of future development trend, the development and utilization of geothermal energy in China has broad prospects.
Energy storage is the core of energy Internet
Chai linliang, director of the finance office Secretariat of Shanxi provincial Party committee, pointed out that at present, China's new energy development momentum is good, the installed capacity accounts for 30%, but the power generation accounts for less than 10%, which is far behind the developed countries with better new energy utilization level. In this regard, Han Xiaoqing, Dean, professor and doctoral director of the school of electrical and power engineering of Taiyuan University of technology, believes that new energy is crucial to the development of China's energy. At present, the main problem of new energy in China's power system is that China's new energy installation accounts for 18% in 2018 and is expected to exceed 50% in 2050. However, in 2018, China's new energy consumption exceeded 100 billion kwh, exceeding the Three Gorges' annual power generation.
Yang Liyou, chief engineer of Jinneng clean energy Co., Ltd. and general manager of Jinneng Clean Energy Technology Co., Ltd., said that the new energy industry has just moved from the era of high subsidies to the era of affordable prices. In the next few years, the industry will be able to use clean, efficient and cheap clean energy in most parts of the world. There is still a long way to go. It needs to promote technological progress and reduce the cost of use , improve conversion efficiency.
Han Xiaoqing believes that as an effective solution to the problem of new energy grid connection, energy storage is the core link of energy supply and demand interaction in the energy Internet, and energy storage technology can be used as a bridge between the power grid and other networks such as natural gas network, heating system, electrified transportation network, etc. Energy storage characteristics will change from high cost, low performance, short life and low density to low cost, high performance, long life and high density. Therefore, it can be predicted that energy storage will exist in the form of light weight, small size, low price, high efficiency and plug and play in the future, which provides a completely different form of energy supply and demand from the traditional power grid.
Promote the deep development of energy revolution
Zeng Shaojun concluded that the key to the future development of wind power lies in the sea, and the core is to solve environmental problems. In terms of solar photovoltaic power generation, the key of crystalline silicon technology path is to further reduce production costs and improve management level, and the film should pay more attention to market application; solar thermal power generation needs more breakthroughs in the construction of commercial demonstration projects, so as to attract investment and achieve large-scale development; the way out for solar thermal utilization lies in engineering application and cross season heat storage; the development of biomass energy The core is to solve the problem of collecting radius of raw materials, which is related to China's legal credit environment; the use of shallow geothermal should focus on environmental impact assessment, and large-scale development and utilization should do well in groundwater recharge and avoid pollution.
Looking forward to China's new energy development in the future, Zeng Shaojun said that the first is distributed development: the distributed development of new energy. In the future, the distributed application and innovative development of photovoltaic, wind power, biomass energy, geothermal energy and other energy systems will become an important part of China's response to climate change and energy security.
Second, clean utilization: that is, clean utilization of traditional energy. To realize the development and utilization of traditional energy resources in a safe, efficient, clean and low-carbon way will be a major change in China's energy development, and will also play a role in promoting sustainable economic and social development. We should vigorously promote the clean utilization of coal-based alcohol ether fuel, coal to oil, natural gas replacement and other ways to promote the clean, efficient and recycling development of traditional energy.
Third, inclusive development: inclusive development of new energy and traditional energy. Characteristics of the new era: the mixed economy is the development direction, and the inclusive development of state-owned traditional energy and private new energy is the best choice to realize "Pareto".
Fourth, multi energy complementary: that is to establish a multi energy complementary energy system with energy storage as the core. Build an efficient and flexible comprehensive energy system and vigorously develop a multi energy complementary system with energy storage as the core. Through the effective combination of wind, light, water and fire energy storage, give full play to the advantages of various power sources, regulate peak load and pressure, improve the capacity of consumption, increase the proportion of new energy applications, alleviate "wind, light and water abandonment", and achieve stable and high-quality development of energy economy.
Five is key technology innovation: key technology research and development and major project layout. In the future, the focus of energy development will change from speed and scale to quality and efficiency. Therefore, we must pay attention to the research and development of key technologies and accelerate the cultivation of new energy development momentum. Sixth, market-oriented reform: Deepening the reform of energy system and mechanism guided by market. The embodiment of deepening the market-oriented reform in the field of energy is to use the market-oriented system and mechanism to promote the in-depth development of the energy revolution.
