“Geothermal is one of the most realistic and competitive energy sources for new energy.†The 4th National Geothermal Resources Development and Geothermal Heat Pump Technology Application Seminar held in Jinan recently came from the Institute of Geology and Geophysics, Chinese Academy of Sciences. The academician of the Chinese Academy of Sciences Wang Jiyu pointed out: "For a long time, the development and utilization of geothermal resources have not received enough attention. As a result, in the rapid development of energy sources such as wind power, solar energy and nuclear energy, geothermal heat has lagged far behind other new energy industry developments. Due value."
The potential value of geothermal in Shandong exceeds RMB 6.5 trillion. According to the introduction of academician Wang Jiming, China is a country dominated by low- and medium-temperature geothermal resources. Geothermal energy is rich in reserves. Taking the province as an example, it is estimated that the amount of geothermal energy stored within a depth of 200 meters is equivalent to 13.14 billion tons of standard coal equivalent, equivalent to 40% of the total coal geological reserves in our province, and the potential economic value of geothermal resources is more than 6.5 trillion yuan.
"Compared to renewable energy sources such as wind and solar energy, geothermal energy is the only renewable energy source that is not affected by weather and seasonal changes," said academician Wang Jirong.
According to reports, the greatest advantage of geothermal is its stability, continuity and high utilization. At the same time, geothermal resources are still a kind of clean, low-carbon and renewable new energy. Exploiting and utilizing geothermal resources is an inevitable trend for the development of green economy, low-carbon economy and circular economy.
Liu Guiyi, deputy director of the provincial shallow geothermal research and promotion center, said that geothermal heat can not only be widely used in heating, bathing, entertainment and aquaculture, but also save energy, protect the environment, and produce great economic benefits. Taking geothermal heating as an example, generally only 16 yuan per square meter, and coal-fired heating fees per square meter reached 27 yuan, a heating season down, a housing area of ​​100 square meters of the family, annual savings of more than 1,000 yuan.
Wang Jixi said: "Geothermal is one of the most realistic and competitive energy sources for new energy sources." It is estimated that the amount of geothermally recoverable resources in the world is quite large, exceeding the annual consumption of global primary energy sources.
“Geothermal resources have great potential for power generation. It is expected that by 2050, the installed capacity of global geothermal power generation is expected to reach 70 JW. If new technologies are used, the installed capacity can be doubled, and geothermal power generation can provide 8.3% of global power supply. "Wang Jizhen said. By then, the world can reduce CO2 emissions by 1 billion tons annually.
Wang Bingjun, director of the State Council's former counselor and director of the Ministry of Housing, Urban and Rural Construction and Environmental Engineering Technology Center, said that the total area of ​​ground-source heat pump utilization in China has exceeded 140 million square meters and the total efficiency exceeds 5000 MW. China’s medium-low-temperature geothermal resources have been ranked first in the world for direct development and utilization. .
“After the national renewable energy demonstration projects and demonstration cities have achieved success, the promotion of renewable energy projects in small cities and towns will inevitably lead the geothermal heat pump industry into a new round of climax. The prospects are encouraging.†Wang Bingjun said, “New things Difficulties are certain, but market growth will remain high."
There are four major problems in geothermal development: "Although geothermal has an irreplaceable advantage, compared with the rapidly developing wind and solar energy industries, the development and utilization of geothermal heat has lagged behind other new energy industries." In this regard, Wang Jixi pointed out that China's geothermal development There are four major problems.
The low level of geothermal resources exploration and evaluation in China has affected the development and utilization of geothermal resources. It is understood that so far, China has not yet conducted a survey on geothermal resources, and only some areas have carried out exploration and evaluation demonstration projects, and the scope of scale is relatively small.
The development of geothermal technology is seriously out of balance. Although China's geothermal low-temperature utilization technology has reached the international advanced level, there is still a certain gap between high-temperature utilization and international comparison. Especially for geothermal power generation, there was no new breakthrough after the completion of the Yangbajing power station in Tibet. At present, geothermal power plants have been built in 24 countries around the world. Its total installed capacity and annual power generation capacity are 10,715 MW and 612 MW respectively, compared with 25 MW in China.
Many key technologies for geothermal utilization have yet to be mastered in China. Wang Jixi stressed: "High-temperature power generation technology has already been mastered in China, and low-temperature power generation technologies still require new technological breakthroughs."
Lack of human resources. At present, talents in China's geothermal utilization face a difficult situation. In this regard, Wang Jiqiu believes that China should focus on cultivating high-level and complex geothermal talents, and must cultivate complex talents who understand both ground technology and underground exploration.
According to reports, due to the constraints of many factors, the development and utilization of geothermal resources in China has been slow to develop. There have been no major technological breakthroughs in the past 20 years. This has also led to a slow progress in the scale of geothermal promotion, limited to public buildings or very few residential communities. Ordinary people know less about this, and most of them are limited to spa bathing.
Liu Guiyi told reporters that when investigating the geothermal utilization industry in our province, it was found that the lack of overall planning and improper use resulted in unsatisfactory system performance. At the same time, due to technical factors causing waste of resources, these issues would not affect the entire industry if they were not solved in time. development of.
Geothermal Development Urgently Needs Policy Support At present, there are still many technical difficulties in the development of geothermal resources. Wang Jijun proposed to establish a national-level geothermal technology research and development platform, strengthen technology research and development, implement demonstration projects, and formulate preferential policies to promote the development of geothermal utilization industries.
“At present, the development of geothermal resources still lacks the problems of unified planning, unsatisfactory management system, and lack of geological monitoring. In this regard, relevant industrial policies will be issued to regulate the situation,†said Wang Jixi.
Wang Jixi said that the National Renewable Energy Law clearly recognizes that geothermal energy belongs to renewable new energy sources. Therefore, its development and use should be supported by national policies. Compared with other renewable energy sources, the utilization efficiency of geothermal power generation reaches 72%. Increasing the installed capacity of geothermal power generation can not only achieve the goal of energy saving and emission reduction and environmental protection, but also improve the power supply and promote economic development. It is recommended to refer to other renewable energy sources. The on-grid price subsidies for energy generation, the development of on-grid tariff subsidies for geothermal power generation, and the promotion of the rapid development of geothermal power generation.
“The total amount of geothermal energy in China is huge. In the new energy industry, geothermal should not be this position, and it should rise from the current ranking to the third or fourth at the end of the ranking,†said Wang Jixi.

JHK Door Industry Beech Veneer Door Skin is popular used to produce nice and classical veneer molded door. Beech veneer is very popular in European and American market. In order to make good door skin, we use good fiberboard and glue, after two times high temperature, the beech veneer will stick on the fiberboard perfect.
Beech in Europe is like Oak in North America. It grows everywhere and gets used for just about everything. It works especially well with accent woods that have a contrasting color, like Mahogany. We pretty much always have plain sliced, plain quarter (rift) and figured in inventory. We favor steamed over unsteamed as do most of our customers. Figured sometimes has such strong character that it will display some lighter grain tones. This is a great wood veneer that isn't that hard to work with and can be used in large doses with little consequence other than having the ability to look very clean and fresh.
