Title | The world's first self-developed geothermal thermovoltaic generator field test breakthrough 1000W class Source | Geothermal Edit | Geothermal small core (add micro-signal: geothermalAI, you can get the relevant information) → This is the geothermal energy online AI geothermal small core edited the 1st article 2024 January 15, Xie Heping academician shenzhen university team 2023 annual summing up meeting and the deep earth engineering intelligence Construction and Healthy Operation and Maintenance National Key Laboratory (Shenzhen University) kick-off meeting was held. Xie Heping said that in 2024, the team will directly produce hydrogen from seawater and geothermal thermoelectric power generation two subversive technologies as soon as possible to promote the scale of industrialization, and contribute to the "development of new quality productivity". At the meeting, academician Xie Heping, director of Deep Earth Science and Green Energy Research Institute of Shenzhen University and director of National Key Laboratory of Intelligent Construction and Healthy Operation and Maintenance of Deep Earth Engineering, introduced in his speech that the team of SZU has achieved five landmark achievements in 2023, namely, the sixth batch of the country's approval/shenzhen's first Chang'e V moon soil samples, the world's first independent research and development of geothermal thermovoltaic power generator field test exceeded 1000W, and completed a world-scale industrialization of direct hydrogen production from seawater and two subversive technologies of geothermal thermovoltaic power generation on dry-heat rock site in Qinghai The world's first dry-heat-rock single-well thermovoltaic power generation field test was completed at the Republic of China dry-heat-rock site; deep coal pressure- and gas-preserving coring was realized for the first time in the international arena; the world's first seawater direct electrolysis hydrogen production technology sea trial was successfully conducted; and the world's first deep-sea solid combustible ice heat preservation and pressure-preserving sampling sea trial was successfully conducted. According to the website of Institute of Hydrogeology and Environmental Geology, Chinese Academy of Geological Sciences (IHEG) on December 8, 2023, funded by China Geological Survey, IHEG, together with Guangzhou Energy Research Institute of Chinese Academy of Sciences, Shenzhen University and other related units, jointly carried out a joint test of dry heat rock single-well heat harvesting-thermovoltaic power generation system in the dry heat rock exploration and test site of Gonghe Republic of Qinghai. During the test period, the maximum instantaneous heat recovery rate of the single well exceeded 2 MW, and the average heat recovery rate of 72 hours reached 1 MW. Compared with the same type of single well heat recovery system in China, the maximum heat recovery rate of the system was increased by nearly 4 times, and the average heat recovery rate was increased by more than 2 times. Under the extreme working conditions (69.7℃ at the hot end and 5.0℃ at the cold end), the extreme power generation capacity of the thermovoltaic motor reaches 1,290.8W, realizing the current world's largest power geothermal thermovoltaic power generation. Previously, in March 2023, Academician Xie Heping introduced in public, the Great Bay Area geothermal resources are very rich, there are 60% area is granite, granite is below the low and medium temperature geothermal. The current geothermal power generation technology is dominated by turbine power generation, which is very inefficient, so how to tackle the research and development of new power generation technology, especially the disruptive and transformative technology of low and medium temperature geothermal power generation, the world is currently tackling and are all at the same starting point. According to Geothermal Plus, since 2019, Xie Heping's team has proposed three new technologies in the field of geothermal power generation: subversive technology for thermovoltaic power generation, transformative technology for magnetic levitation power generation, and exploratory technology for in-situ power generation. At present, thermal voltaic power generation has realized the development of three generations of thermal voltaic generator principle prototypes after four years of research, and has achieved a leapfrog breakthrough of 10W class-100W class-1000W class. The Institute of Deep Earth Science and Green Energy of Shenzhen University was established in March 2018 by Academician Xie Heping as the director, and is committed to innovative research and exploration in the fields of deep earth science and low-carbon green energy, and its research directions include deep earth science and in-situ rock mechanics, deep earth and deep sea deep space fidelity coring and prospecting theory and technology, engineering perturbation rock dynamics, seawater hydrogen production principle and technology, low and medium temperature geothermal power generation theory and technology, low-carbon and CCUS technology, and low-carbon power generation theory and technology. Low carbon and CCUS technology, etc. The National Key Laboratory of Intelligent Construction and Healthy Operation and Maintenance of Deep Earth Engineering was approved in 2023 on the basis of the existing State Key Laboratory of Deep Geotechnics and Underground Engineering of China University of Mining and Technology (CUMT), which was reorganized by China University of Mining and Technology (CUMT), Shenzhen University (SZU) and Sichuan University (SU), with Academician Xie Heping as the director. The research direction of the National Key Laboratory of Intelligent Construction and Healthy Operation and Maintenance of Deep Earth Engineering (Shenzhen University) includes dynamic (static) mechanics of deep-earth engineering rocks, deep geothermal and clean energy development, deep-earth engineering materials and intelligent construction, deep-earth resource in-situ fluidized mining and healthy operation and maintenance, and deep-space and deep-sea fidelity coring prospecting. Academician Xie Heping put forward the requirements of "seeking newness, seeking truth and seeking reality" to all members of the team and laboratory. "Seek new", that is, to focus on the world's scientific frontiers and major national strategies, to do from 0 to 1 of the original innovation, in the selection of the direction and the development of the field, the key is to "do what others have not done, to do beyond what others have done"; "" Truth-seeking" is to have an objective, rigorous and rational attitude of governance and the scientific spirit of truth-seeking, in accordance with the requirements of President Mao Junfa, to achieve "real problem solving, real problem solving, real problem solving;" "Truth-seeking" is to seek truth from facts, and to be practical and realistic, with a strong sense of responsibility. That is, to seek truth from facts, down-to-earth, hard-working and persistent will to struggle.
