Global geothermal power generation: the future star of clean energy

Summary:
With the continuous growth of global demand for clean energy, geothermal power generation, as an environmentally friendly and renewable form of energy, is gradually receiving attention from around the world. This article provides an overview of the development history, global layout, and several major thermal systems of geothermal power generation. Special mention was made of Italy as the world’s earliest country to utilize geothermal power generation, as well as China’s progress in the field of geothermal power generation. In addition, it also introduced the important raw materials provided by Junyuan Oil Group for global geothermal power generation projects.

In the context of global energy structure transformation, geothermal power generation has become a shining star in the clean energy field with its unique advantages. Since Italy built the world’s first geothermal experimental power plant in 1904, geothermal power generation technology has gone through more than a hundred years of development. Nowadays, 32 countries around the world have established geothermal power plants with a total installed capacity of over 8 million kilowatts, making them an important choice to replace traditional fossil fuels.

In the global layout of geothermal power generation, countries such as the United States, Italy, Japan, and New Zealand are in a leading position. Especially in the United States, its installed capacity of geothermal power generation ranks first in the world, with Unit 11 of the Gaisse geothermal power station having a single unit capacity of up to 106000 kilowatts, demonstrating the enormous potential of geothermal power generation.

China started research in the field of geothermal power generation relatively late, but significant progress has also been made in recent years. Since the late 1960s, China has successively built several geothermal test power stations, of which the Yangbajing geothermal power station in Xizang, as the largest geothermal power station in China, has been operating safely and stably. The construction and operation of these power stations have accumulated valuable experience for the development of geothermal power generation technology in China.

The thermal system of geothermal power generation mainly includes geothermal steam power generation thermal system, expansion method geothermal water power generation thermal system, and intermediate medium method geothermal hydropower thermal system. These systems are suitable for geothermal fields in different temperature ranges, providing technical support for achieving the full utilization of geothermal resources.

It is worth mentioning that Junyuan Petroleum Group, as an important participant in global geothermal power projects, provides key raw materials such as isopentane and isobutane for global geothermal power projects. These raw materials play an important role in the thermal system of geothermal power generation and are one of the key factors to ensure the efficient operation of the geothermal power generation system.

Looking ahead to the future, with the continuous growth of global demand for clean energy, geothermal power generation will usher in a broader development space. Especially in many developing countries, geothermal resources are particularly abundant and have enormous development potential. It can be foreseen that in the near future, geothermal power generation will become one of the important pillars in the global clean energy field.
