The 2023 ZGC Forum—the “Second Carbon Peak Carbon Neutral Technology Forum” opened in Beijing.

Nearly 400 representatives participated in the conference, and the number of online participants exceeded 200,000. The social response was enthusiastic. The theme is “Open Cooperation Shared Future”, conduct in-depth exchanges around “development and innovation of key energy technologies”, and explore technologies for energy revolution and industrial green transformation and upgrading from the fields of energy development strategy, new power system, renewable energy and energy storage path.

Xu Chunming, an academician of the Chinese Academy of Sciences, delivered a keynote speech and said that the only option for the strong volatility and instability of renewable electricity and the stable operation of “long-term optimal” required by chemical processes is energy storage. Lithium-ion batteries are an important material used in common energy storage methods, but their development is limited by resources and prices. If we can find a low-cost, large-scale, and long-term energy storage process, then it will have a great impact on electrochemical energy storage. There will be more room for development.

Xu Chunming has his own views on how to reduce the cost of energy storage. Since the benefit space of energy storage itself is not large enough at this stage, it can be solved by improving the efficiency of energy storage and reducing the cost of some key materials. At the same time, it is also necessary to consider how to combine the source and the load. Reducing storage costs is a systematic issue, and it is also a direction that the energy storage industry needs to continue to improve for a long period of time in the future.

Chen Zhongwei, academician of the Royal Canadian Academy of Sciences, said that electrochemical energy storage is an important guarantee for new energy applications. The most important criteria for evaluating electrochemical energy include four parameters. The first is cost, the second is safety, the third is energy density, and the fourth is power density. Future energy upgrades can be based on these four parameters. standards to improve.

The potential of the large-scale energy storage market in the future is huge, and it will reach more than 100 times that of the current electric vehicle market, which also means that the demand for batteries will rise in a straight line. In the context of dual carbon, it is necessary to consider the sustainability of batteries, including the regeneration of materials, the mutual balance between energy and resources, and the mutual balance between energy and battery safety.

Xu Nanping, an academician of the Chinese Academy of Engineering, said that the “double carbon” goal is both an opportunity and a challenge for China. The key to turning challenges into great opportunities lies in technological innovation. Among them, zero-carbon energy costs are the main driving force for national competitiveness and the application of new technologies to reduce emissions in the industry. From the demand side, the state will vigorously support the transformation of energy structure consumption, expand the installed capacity of batteries, and further open up the energy storage market. From the power generation side, promote the commercialization of building-integrated photovoltaic distributed power generation, and pilot photovoltaic + energy storage projects.

In order to achieve the goal of carbon peaking in 2030, Xu Nanping suggested focusing on the development of benchmark technologies such as photovoltaics and large-scale long-term chemical energy storage, and building a photovoltaic-energy storage equipment system.
Focusing on the dual-carbon strategic goals, it is incumbent on us to seek green energy and develop the energy storage industry together!
