On the eve of new energy technology breakthrough, are we ready

According to the analysis of the report, the current energy Internet research still needs to pay attention to the following issues: First, pay attention to the energy Internet architecture and core equipment technology research, and make breakthroughs in the intelligent energy production and consumption, energy Internet system planning, multi-energy flow energy exchange and routing technology, energy intelligent transmission technology, and intelligent network collaborative control technology; Second, pay attention to the technology research of big data collection, mining and utilization of energy systems, and make breakthroughs in energy Internet communication, energy information and information physical integration, energy big data application technology, and energy Internet management technology; The third is to pay attention to the landing transformation of energy Internet technology, and make breakthroughs in the research design, demonstration application, and landing implementation of multi-disciplinary, information network infrastructure and energy infrastructure link.

How does China fare in the New energy R&D race?

The total contribution of China in the field of new energy research is large, and the contribution of high-quality research is also high. However, 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 Strategic Advisory Institute of Science and Technology of the Chinese Academy of Sciences, introduced that the report compared the main contributions of the leading countries in new energy research to the development of the field and found that there are differences in research efficiency among countries. China's number of published documents in the eight new energy technology fields ranked first and second in the world, indicating that it has a strong degree of activity in the main directions of new energy research. A comprehensive analysis of the research influence of eight technical fields (citation frequency and number of high-quality research papers) shows that the number of high-quality papers in China ranks top six in all technical fields, but the citation frequency of papers in most fields ranks relatively low, indicating that China's research efficiency in the field of new energy technology still needs to be further improved.

For example, in the country comparison, the number of published papers in the field of energy Internet in China is the largest, and the number of high-quality papers is also in the lead, indicating that the Chinese scientific research community pays great attention to the theoretical frontier research of energy Internet, and has certain competitiveness in the field of energy Internet research. However, from the ranking of countries with the frequency of citations, China only ranks fifth in the world, indicating that there is still a certain gap between the influence of Chinese papers and that of the United Kingdom and the United States, and it is still necessary to strengthen the research of key core technologies and improve the research level in the field of energy Internet.

But China also shines in a number of areas. Tan Xianchun said, for example, China's energy storage industry has rapidly become a global up-and-comer. In particular, the report mentions that the "Energy Storage Industry Research White Paper 2020" jointly released by the Energy Storage Committee of the China Energy Research Society shows that the cumulative installed capacity of global battery energy storage in 2019 is 9520.5MW, of which the cumulative installed capacity of lithium-ion battery energy storage accounts for 88.6%. Although China's energy storage industry started late, but in recent years, the development speed is remarkable, the cumulative installed capacity of battery energy storage has reached 1709.6MW, of which the cumulative installed capacity of lithium-ion battery energy storage accounted for 60%, in 2015-2019, the cumulative installed capacity of lithium battery energy storage increased by more than 100% per year.

The report puts forward recommendations for the development of new energy in China:

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 and solar energy and the smart grid industry has made energy storage technology an urgent technical barrier for countries around the world to overcome. Large-scale and efficient energy storage technology is the key technology to achieve the popularization of renewable energy, which can solve the difference between power generation and electricity consumption and the impact of intermittent renewable energy generation directly connected to the grid, and is a soft link key node with flexible, inclusive and balanced functions in the future energy system. China should further improve the policy mechanism to promote the development of energy storage industry, guide long-term capital investment through financial and market-oriented means, build energy storage scientific and technological innovation and technology reserve system, strengthen new energy and energy storage integrated application research, and promote large-scale energy storage technology breakthroughs and commercial applications.
