Multi-energy complementarity will be the main feature of clean energy development

Deloitte China recently released the "2017 Clean Energy Industry Report", which explores the development trends of China's clean energy industry in detail, and includes several sub-industries from solar energy, wind energy, new energy vehicles, solid waste treatment, water treatment and new technologies of energy conservation and environmental protection. The opportunities and challenges they face are analyzed.

The "Thirteenth Five-Year Plan" has formulated a number of indicators for China's 2020 energy structure adjustment plan: the proportion of non-fossil energy consumption has increased to more than 15%, the consumption of natural gas has reached 10% of gravity, the proportion of coal consumption has fallen to below 58%, and power generation The proportion of coal consumption in coal consumption has increased to more than 55%. This means that clean energy will play a more important role in the future.

Zhou Jinchang, Deloitte China ’s National Leading Partner in Technology, Media and Telecommunications said: "From the perspective of data, China ’s total investment in clean energy has always been higher in the world in recent years, growing from less than US $ 10 trillion in 2005 to 2015. More than 100 trillion US dollars, the installed capacity and output of various types of clean energy also ranks first in the world. Compared with the traditional energy industry, the clean energy industry has higher requirements for research and development, investment, correspondingly higher costs, and profitability. Weak, and China ’s clean energy industry is more affected by policies and subsidies, and the participation of state capital is higher. However, with the development of the industry and policy encouragement in recent years, we can see that the clean energy industry will pay more attention The law of independent market development will give full play to the role of price regulation and develop a more sound energy financial system. "

At the same time, multi-energy complementarity is also one of the main features of clean energy development in the future. Energy complementary systems are not only conducive to the development of clean energy, increasing the proportion of new energy, but also reducing the level of high pollution and high energy consumption such as thermal power. Got. As of 2015, renewable energy accounts for a certain percentage of global power generation, including hydropower, wind energy, biomass energy, solar photovoltaic, solar thermal power, geothermal energy, and ocean energy. In the future, these types of renewable energy will combine non-renewable energy to create a cleaner and more efficient energy complementary power generation system.

According to the data from 2016, although China's renewable energy generation has far surpassed the second and third places in the United States and Germany, hydropower accounts for more than half of the renewable energy power generation. It shows that hydropower may have a certain negative impact on the ecological environment of local waters. Therefore, in the future, China will focus on the development of two types of clean energy: solar photovoltaic and wind power. Yu Yang, Deloitte China ’s Leading Partner in Clean Technology Industry, said: "Although China ’s wind and photovoltaic development has been at the forefront of the world, the problem of abandoning light and wind is still serious. Therefore, in the future, countries will pay more attention to system optimization and innovation. Development model, actively constructing a smart energy system. Not only improving the peak shaving capability of the system as a major measure to supplement the shortcomings of electric power development, but also accelerating the construction of high-quality peak shaving power sources, actively developing energy storage, transforming the dispatching operation mode, and speeding up the breakthrough in grid balance And adaptive operation control technologies to significantly increase the power system's ability to shave peaks and absorb renewable energy. "

In addition, with the encouragement of policies, the photovoltaic industry will develop in synergy with traditional industries and play a huge role in the development of poverty alleviation projects, such as "agricultural-optical complementarity" and "fish-light complementarity" and other cooperation models should be revived and achieved significant results. Deloitte predicts that during the "Thirteenth Five-Year Plan" period, the contribution of the solar industry to China's economic output value will exceed one trillion yuan, providing about 7 million jobs. It is worth mentioning that the solar energy industry may bring more innovative investment and financing models to our country. Yu Yang believes: "In the future, the better economic benefits of the photovoltaic industry will attract more social capital to invest, and more photovoltaic industries will also bring multiple benefits to society and form a virtuous circle."

Zhou Jinchang concluded: "Energy green and low-carbon development is still the main object encouraged by the government, and the clean energy industry has always been supported by policies. The government still regards the development of clean and low-carbon energy as the main direction of adjusting the energy structure and gradually reducing the proportion of coal consumption. Increase the proportion of natural gas and non-fossil energy consumption, significantly reduce the intensity of carbon dioxide emissions and pollutant emissions, optimize the layout and structure of energy production, and promote the construction of ecological civilization.
