As lengthy like a reasonable premise, exploitation of shallow geothermal power energy won't result in geological problems; therefore the geological atmosphere monitoring should be done.
And wind energy, Solar Power Other new Energy As shallow geothermal power energy has additionally been within the "Alternative Energy Law" was clearly urged through the inclusion of the introduction of new energy range, but in the promotion of using, the received much less focus on the previous. Lately, the Secretary of state for Land making great efforts to build up the area in the making of shallow geothermal power energy, questioned on the process of China Geological Survey, Research and Extension shallow hypothermia, deputy director of LI Ning.ng.
Shallow geothermal power energy boost economical
With new energy, wind energy, solar power and folks have lengthy been familiar, however the reference to geothermal power energy, particularly in shallow geothermal power energy, lots of people still feel strange. Inside your opinion, exactly what is shallow geothermal power energy? Could China shallow geothermal power energy development and usage of condition to perform a presentation?
LI Ning: Shallow geothermal power energy is less than 200 meters subterranean soil and groundwater reserves in the earth thermal energy, using warmth pumps take advantage of technology for acquisition, not just heating, but additionally cooling. And in comparison with other causes of energy, shallow geothermal power energy has broadly distributed, could be recycled, large reserves might be near to use the benefits of a clear energy. With China's rapid economic growth, the worsening energy situation. Economical keeps growing in present day shallow geothermal power energy being an important new energy, its development and usage of sustainable development being an important way, but Ground Source Electric Technology could be "timely help" so shallow geothermal power energy use and development possible.
By June 2009, China's use of shallow geothermal power cooling and heating from the construction projects happen to be 2236, construction section of nearly 80 million square meters, which 80% concentrated within the Beijing, Tianjin and Liaoning along with other southern parts of North China and Northeast. At the moment, Shenyang, Beijing's development and utilization is towards the top of the. Beijing has a lot more than 1,800 million square meters of structures using shallow geothermal power cooling and heating, Shenyang City, a lot more than 20 million square meters. In 2008, our country with the development and usage of shallow geothermal power energy, to attain 19.87 million a lot of co2 pollutants. The following 5 years, China increases within the construction area within 200 meters of shallow subterranean development and usage of geothermal power energy, to help promote energy conservation.
Rational exploitation won't cause geological problems
Primary factors which presently modify the promotion of using shallow geothermal power energy?
LI Ning: to begin with due to variations in geological conditions. Not in almost any condition does apply underneath the shallow geothermal power energy, not really exactly the same city all of the geological models are appropriate to be used, so efforts have to increase exploration and evaluation.
From technology itself, the expansion and usage of shallow geothermal power energy mainly with the subterranean Water Source Electric Systems and Ground Source Electric system to attain. Both of these technologies each their very own weak points and groundwater source electric system by water and geologic conditions Geothermal power electric system a lot more than the first investment, covers a place of major.
And geothermal power development and usage of a method Project Need Air conditioning Ac and also the mixture of geological drilling technology, have to unite the different departments. Now, the architectural design sector generally don't realize, or even the maturity from the technology skeptical domestic ground source electric technology associated with fundamental information and it is not so healthy at the moment and excellent. Design Institute for Mental dare not rashly attempt Striving; customers don't want to risk using ground source electric technology affected in certain areas to advertise speed.
From economic factors, not every one of the floor source electric systems engineering are economic and reasonable. The present utilization of ground source electric system, the first investment than traditional boiler home heating is greater. However, when the design is uncommon, can make energy-saving operation to attain preferred objective.
Accessory for the insurance policy, some areas use ground water source electric system and also the protection water assets policy of conflict, it is essential to safeguard the groundwater assets because the prerequisite for that development and usage of shallow geothermal power energy make relevant preferential guidelines.
Geothermal power energy development and usage of shallow groundwater extraction involved recently, many metropolitan areas due to over-exploitation of groundwater has triggered surface subsidence along with other geological problems triggered much concern. Shallow geothermal power energy programs along the way may cause the hazard?
LI Ning: It's we have to take seriously. A couple of years back to Beijing to build up geothermal power heating for that Olympic village, seemed to be undecided concerning the leadership of geothermal power exploration ultimately wouldn't cause geological problems? So that they invite lots of domestic and worldwide geothermal power experts, opened up a national geothermal power workshop.
