Global geothermal is "hot" green future will come

The energy shortage caused by geopolitical conflicts has further strengthened the determination of Europe and the United States to develop green and low-carbon energy. On the one hand, Europe and the United States attach importance to the clean supply of fossil energy, and on the other hand, promote the development of new energy. In view of the large scale of building heating and cooling energy consumption and the high proportion of energy consumption, energy substitution has become an important policy re-optimization entry point, and the status of geothermal energy has been upgraded again, and the development speed has been accelerated. The important reasons for the importance of geothermal energy are the stability of supply and widespread distribution. Although solar, wind and ocean energy are also clean renewable energy sources with unlimited supply, they are limited by factors such as seasonal changes and are not available anytime and anywhere. In contrast, geothermal energy, especially shallow geothermal energy, is widely available around the world, is not affected by seasonal changes and climatic conditions, and can be used locally to heat and cool buildings. The geothermal energy that people usually ignore is actually a clean renewable energy that can be used almost indefinitely around, and its potential is being gradually tapped out.

"Both safe and low-carbon" has become the basic principle followed by the transformation and development of China's energy industry

The global geothermal energy market is expected to reach $9.4 billion by 2027, with a compound annual growth rate of 5.9%. Under this trend, the practice of developing geothermal energy in Europe and America has certain reference significance for our country.

China is a big energy consumer, and coal accounts for about 57% of energy consumption, far higher than the world average. At the same time, China is a big country of direct utilization of geothermal energy, but the utilization of geothermal energy accounts for a relatively low proportion of total energy consumption, which does not match its resource potential. China has put forward the goal of reaching the peak of carbon before 2030 and achieving carbon neutrality before 2060, which determines that "safe and low-carbon" has become the basic principle followed by the transformation and development of China's energy industry.

In the important period when China has completed the building of a moderately prosperous society in all respects and is moving towards the second centenary goal, improving people's living standards and optimizing the industrial structure are important symbols of high-quality development. With the continuous improvement of China's urbanization level and the steady advancement of new rural construction, allowing urban and rural buildings to rely on renewable energy to achieve heating and cooling is an important measure to help high-quality development. According to the Ministry of Natural Resources data, the national ground source heat pump heating and cooling area from 2010 100 million square meters of rapid growth to 2020 800 million square meters, the average annual compound growth rate of 20%, to the end of the "fourteen five" will increase to 900 million square meters, geothermal development has a good basis for development, including China Petrochemical, including a number of enterprises are engaged in geothermal heating business.

From the perspective of the development trend, the future heating and cooling is not only needed in the northern region, but also in the southern region, especially due to historical reasons, some hot summer and cold winter areas have not been able to achieve central heating in the past, resulting in extreme cold weather when people's lives are widely affected. Nowadays, with the improvement of the level of economic development, the call for winter central heating in hot summer and cold winter areas is increasing. If you rely on fossil energy to ensure winter heating, it is bound to increase the overall energy supply and carbon emission reduction pressure, which does not match the "dual carbon" direction and basic requirements of regional economic development. The development of renewable energy is an ideal and realistic choice to enable hot summer and cold winter areas to achieve heating and cooling without increasing energy supply pressure and environmental pressure. Therefore, the promotion of geothermal energy heating and cooling is of great significance in giving play to the advantages of adequate supply and wide distribution of geothermal energy.

China's geothermal industry has entered a flourishing period

Tight gas supplies in Europe due to geopolitical conflicts are driving demand for geothermal energy. In terms of geothermal power generation, there are currently 142 geothermal power plants in operation in Europe with a total installed capacity of 3.5 GW. More than 30 geothermal power Wells are expected to be drilled in Europe in the next five years. In terms of geothermal heating, the shortage of natural gas in 2022 has pushed the demand for ground source heat pump markets in Europe to a record high, with more than 141,300 ground source heat pump systems installed, and it is expected that by 2030, the installed amount of ground source heat pump in Europe will be 30 million units, which can replace 35 billion cubic meters of natural gas.
