Turning Xinjiang’s Solar Energy into Hydrogen Energy

Xinjiang is rich in sunlight resources and is also suitable for laying large-area photovoltaic cells. However, solar energy is not stable enough. How can this renewable energy be absorbed locally? According to the requirements put forward by the front headquarters of Shanghai Aid Xinjiang, the Shanghai Academy of Sciences is organizing the implementation of the “Multi-energy Complementary Green Hydrogen Storage and Use Xinjiang Integrated Application Demonstration Project”. This project is located in Anakule Township, Bachu County, Kashgar City. It will convert solar energy into hydrogen energy and use fuel cells to provide power and heat for local enterprises and villages. It will provide a worthy promotion for my country to achieve the goal of carbon peak and carbon neutrality.

The Plan

Qin Wenbo, Dean of the Shanghai Academy of Sciences, said that technological innovation to support the “dual carbon” goal often requires cross-unit and cross-professional cooperation, not only for new technology research and development but also for concept verification, engineering design and trial operation in various application scenarios. . In order to do a good job in the Kashgar project that integrates multiple technologies, the Shanghai Academy of Sciences, under the guidance of the Municipal Science and Technology Party Committee and the Municipal Science and Technology Commission, adopted the “two lines and two divisions” organization plan. The “two lines” refer to the administrative line and the technical line. The administrative line is responsible for resource support, progress monitoring and task scheduling, and the technical line is responsible for specific R&D and implementation; the “two divisions” refer to the chief commander on the administrative line and the chief designer on the technical line.

In order to do a good job in scientific research and organization in the field of new energy, the Shanghai Academy of Sciences recently relied on Shanghai Aerospace Industry Corporation to set up a new energy technology research institute, with hydrogen as the core to develop complementary fusion technologies for gaseous energy and smart grids, and explore application scenarios for carbon reduction technologies. . Director Dr. Feng Yi said that Shanghai Aerospace is a pioneer in new energy technologies such as photovoltaic cells, lithium battery energy storage, and power generation micro-grid systems. Various technologies and equipment have withstood tests in space. The Institute of New Energy, Shanghai Academy of Sciences attempts to provide integrated solutions for the micro-practice of the “dual-carbon” strategy through integrated innovation.

Demand information from the front headquarters of the Shanghai Aid to Xinjiang shows that it is necessary to organize the development of solar power generation, energy storage and comprehensive application demonstration systems. In response to this demand, the Shanghai Academy of Sciences organized a number of scientific research institutions and enterprises to carry out the research and demonstration work of the “Multi-energy Complementary Green Hydrogen Storage and Use Xinjiang Integrated Application Demonstration Project”.

At present, the basic plan for the Kashgar project has been released, including a green hydrogen storage integrated system, a multi-energy efficient and stable power supply adjustment device, a fuel cell device suitable for desert environments, and a surface water efficient hydrogen production device in Xinjiang. Feng Yi explained that after photovoltaic cells generate electricity, they are input into the lithium battery energy storage system. The electricity is used to electrolyze water to produce hydrogen and convert solar energy into hydrogen energy. Compared with solar energy, hydrogen energy is easy to store and transport, and can be used as a raw material for fuel cells for combined heat and power. “The hydrogen production, hydrogen storage, fuel cell and other equipment yunyi designed are all containerized, which is easy to transport and suitable for use in various parts of Xinjiang.”

There is a large demand for electricity and heat in the deep processing of agricultural products in the park where the Kashgar project is located, and the combined heat and power supply of fuel cells can just meet the demand. According to estimates, the income generated by the power generation and heating of the Kashgar project can cover the project operation and maintenance costs.’

The person in charge of the Science and Technology Department of the Shanghai Academy of Sciences stated that the development of the Kashgar project has multiple meanings: one is to provide high-efficiency, low-cost, replicable and popularizable technical routes and solutions for the consumption of new energy in the central and western regions; the other is modular design and containerized technology. Assembly, convenient transportation and use are very suitable for the application scenarios in Xinjiang and other western regions of my country; third, through the export of science and technology, it is expected to lay a solid foundation for Shanghai to participate in the nationwide carbon trading in the future, and to achieve Shanghai’s “dual carbon” goal more smoothly Provide technical support.
