Energy is not only the blood of modern industry, but also the cornerstone of normal life.

Wind energy, solar energy, biomass energy.

Hydrogen energy will be an important medium for building a future energy system and realizing energy reform.

Guo Jianfeng, a researcher at the Institute of Science and Technology Strategy Consulting of the Chinese Academy of Sciences, said that through the analysis of published papers, it is found that new energy technologies are in a period of accelerated development.

According to Guo Jianfeng, statistics on the top 10 papers with the highest frequency of citations can reveal the research directions that different new energy technology fields around the world pay attention to and focus: Biomass energy research mainly focuses on lignin pyrolysis, catalysts, pretreatment, microalgae biofuels, and biology.

In these fields, both paper statistics and scientist interviews have found that hydrogen energy and solar energy are two new energy sources that everyone pays attention to.

The report introduces: In the future energy system, hydrogen energy is an important secondary energy source for carbon reduction, and the research interest in hydrogen production, hydrogen storage, and the transportation and utilization of hydrogen energy is growing rapidly.

Hydrogen energy is an important entry point to boost the deep decarbonization of the energy system.

The research and development of zero-carbon solar fuel technology is the focus of great attention in the scientific research community.

Industrialization has encountered a bottleneck, who is the "blocker" in the application of new energy?

The global technology conversion rate of research results in the new energy field is generally low, and the integration of production, education and research needs to be strengthened; energy storage technology and energy Internet have attracted global attention

Chen Wei, deputy director and research librarian of the Strategic Information Center of the Wuhan Literature and Information Center of the Chinese Academy of Sciences, concluded that the global technology conversion rate of research results in the new energy field is generally low, and the integration of production, education and research needs to be strengthened.

The results show that the domestic and foreign markets for energy storage, solar energy and hydrogen energy technology research have received the highest attention, while the technologies with relatively high industrial conversion rates are energy storage, biomass energy and solar energy technology.

Among the new energy technologies, energy storage technology and energy Internet are the most concerned.

Energy storage technology is an important component of the modern energy system.

With the widespread application of energy storage technology in energy production, consumption and low-carbon smart transformation, the need to improve the safety, energy density, capacity scale, endurance, service life and lower battery costs of energy storage batteries is becoming more and more urgent.

　　Energy Internet is a new type of infrastructure for modern energy systems.

　　Under the global carbon neutral scenario, the energy system will have the basic attributes of diversification, intelligence, safety, and flexibility, which means that the importance of research on energy Internet technology and smart energy system technology will be highlighted.

　　According to the analysis of the report, the current energy Internet research still needs to pay attention to the following issues: First, focus on the energy Internet architecture and core equipment technology research, in the intelligentization of energy production and consumption, energy Internet system planning, multi-energy flow energy exchange and routing technology, energy intelligence Breakthroughs have been made in transmission technology and intelligent network collaborative control technology; the second is to focus on the research of energy system big data collection, mining and utilization technology, in the energy Internet communication, energy informatization and cyber-physical integration, energy big data application technology, energy Internet Breakthroughs have been made in management technology and other aspects; the third is to focus on the implementation and transformation of energy Internet technology, and have made breakthroughs in the research and design, demonstration applications, and implementation of multidisciplinary interdisciplinary, information network infrastructure and energy infrastructure links.

　　How does China perform in the new energy R&D competition?

　　China's total contribution to new energy research is relatively large, and the contribution of top high-quality research is also relatively high; but compared with developed countries, the overall efficiency of research still needs to be improved

　　Tan Xianchun, deputy director and researcher of the Institute of Sustainable Development Strategy of the Chinese Academy of Sciences Science and Technology Strategy Consulting Institute, introduced that the report compared the main contributions of new energy research leading countries to the development of the field, and found that countries have differences in research efficiency.
China's publication volume in the eight technical fields of new energy ranks among the top two in the world, indicating that it has a strong degree of activity in all major directions of new energy research.
Comprehensive analysis of the research influence of 8 technical fields (the average citation frequency and the number of high-quality research papers), China ranks in the top six in the number of high-quality papers in all technical fields, but the citation frequency of papers in most fields is relatively high Later, it shows that China's research efficiency in the field of new energy technology still needs to be further improved.

　　For example, in the country comparison, China has the largest number of published papers in the field of energy Internet, and the number of high-quality papers is also leading, indicating that the Chinese scientific research community is highly concerned about the frontier research of the energy Internet and has certain competitiveness in the field of energy Internet.
However, judging from the ranking of countries by the frequency of citations of papers, China is only ranked fifth in the world, indicating that the influence of Chinese papers is still far behind that of the United Kingdom and the United States.
It is still necessary to strengthen key core technology research and improve the energy Internet.
Field research level.

　　But China has also performed very well in many areas.
Tan Xianchun said, for example, the development of China's energy storage industry has quickly become a rising star in the world.
The report specifically mentions that the "Energy Storage Industry Research White Paper 2020" jointly issued by the Energy Storage Special Committee of the China Energy Research Society and others shows that the cumulative installed capacity of battery energy storage worldwide in 2019 is 9520.
5MW, of which the cumulative installed capacity of lithium-ion battery energy storage The scale accounts for 88.
6%.
Although China’s energy storage industry started late, it has developed at an impressive pace in recent years.
The cumulative installed capacity of battery energy storage that has been put into operation reached 1709.
6MW, of which the cumulative installed capacity of lithium-ion battery energy storage accounted for 60%.
In 2015— In 2019, the cumulative installed capacity of lithium battery energy storage increased by more than 100% annually.

　　The report puts forward suggestions on the development of China's new energy:

　　First, the breakthrough and popularization of large-scale energy storage technology is a strong support for the development of renewable energy.
The rapid rise of renewable energy such as wind energy and solar energy, as well as the smart grid industry, has made energy storage technology a technical barrier that countries all over the world must overcome.
Large-scale high-efficiency energy storage technology is a key technology to realize the popularization and application of renewable energy.
It can solve the time difference between power generation and electricity consumption and the impact of intermittent renewable energy power generation directly on the grid.
It is the future energy system that is flexible and inclusive The key node of soft link with balance function.
China should further improve the policy mechanism to promote the development of the energy storage industry, guide long-term capital investment through financial and market-oriented means, build an energy storage technology innovation and technology reserve system, strengthen research on the integrated application of new energy and energy storage, and promote large-scale energy storage technology Breakthrough and commercial application.

　　Second, hydrogen energy will become an important medium for building a future energy system and realizing energy reforms.
With the low-carbon and carbon-free transition of human society, the breakthrough and utilization of hydrogen energy technology has become an important direction for the development of clean energy.
Many countries and regions around the world have issued a strategic roadmap for hydrogen energy development, raising the hydrogen energy plan to a national strategic level.
As an important energy medium for the interconnection, complementation and collaborative optimization of multiple energy networks, hydrogen energy can increase the utilization rate of renewable energy, realize the coupling of the power grid and the gas network, increase the flexibility of the power system, and also have the function of energy storage, through the electrolysis of renewable energy.
Hydrogen is produced from water to realize energy consumption and storage.
Therefore, it is necessary to strengthen the top-level design of hydrogen energy, clarify large-scale application scenarios, reasonably propose hydrogen energy development roadmaps in different scenarios, and formulate corresponding standards and specifications to accelerate the development of the green hydrogen production, storage, transportation, and application industrial chain.

　　Third, breakthroughs in solar fuel technology and cost reductions will help reduce oil dependence.
Solar fuel technology is gradually developing from basic scientific research to industrial viable technology, which is expected to fundamentally change the status quo of over-reliance on fossil resources in the energy and chemical industries.
The advancement of solar power generation technology and wind power generation technology will further reduce the cost of power generation, driving the electrolysis of water from renewable energy to produce hydrogen rapidly becoming a green and sustainable solar fuel production route.
The key to using solar energy to efficiently convert water and carbon dioxide into fuels or chemicals is how to reduce costs and improve efficiency.
China should continue to increase the research and development of solar fuel technology, strengthen the research and application of integrated application technology of solar power technology and construction and other infrastructure, select regions with abundant sunlight resources to carry out typical demonstration projects, and promote the industrial production of solar technology.

　　Fourth, the Energy Internet will give full play to the dual advantages of "Internet +" and smart energy to achieve overall energy allocation and optimization.
Energy Internet can realize the reconstruction of energy production and consumption order, deeply integrate energy production, transmission, storage, consumption, and market operations with information and communication technology, create new business models, and realize a new energy ecosystem of energy sharing.
The construction of the Energy Internet needs to strengthen the integrated application of mobile Internet, cloud computing, big data and the Internet of Things in the smart grid, build a financial support platform, strengthen the management system for the construction of shared energy infrastructure, realize the marketization of the energy Internet, and build a safe and efficient , Sustainable smart energy system.
China should actively promote the research and development of key technologies of the Energy Internet, strengthen the interconnection between different energy networks, promote the construction of comprehensive energy network infrastructure, and improve the energy Internet services and management and operation mechanisms.
