Professor Ma Weibin and associate professor Gong Yulie, from Geothermal Laboratory of Guangzhou Institute of Energy Conversion (GIEC) attended WGC2010 co-convened by International Geothermal Association (IGA) and the Indonesian Geothermal Association (INAGA) in Bali of Indonesia from Apr 24 to 30.

About 2000 representatives from 83 different countries and areas took part in the congress and about 1000 papers were submitted.

The conference theme was “geothermal: the energy to change the world”, which covers about 39 topics such as assessment of geothermal resources, geothermal drilling technology, geothermal power, geothermal direct use (including ground source heat pump), enhanced geothermal systems (EGS). Among of them, the discussion about EGS, being considered as the future of geothermal energy, attracted great interests of the scholars and became a hot spot in the congress. 9 academic fields regarding EGS project were discussed, including overviews, exploration, seismic analysis, fracture analysis, chemical processes, Australian Cases, economics, and emerging concepts.

In technical session, Dr. Gong Yulie and Master Luo Chao presented Thermodynamic analysis of geothermal power generation combined flash system with binary cycle and An absorption refrigeration system used for exploiting mid-low temperature geothermal resource two papers, respectively, which attracted great interests by the scholars from other countries.

During the congress, scholars and professors from China discussed and exchanged their opinions about the prospects of geothermal energy, geothermal power generation and EGS in China. Finally they appealed unanimously that Chinese Geothermal Association should be set up in China to promote our geothermal resource development, especially on geothermal power generation.

WGC is held each five years to provide the latest technology and data about geothermal exploitation and technology communication venue for scholars. The WGC2010 held in Bali was a new milestone for worldwide geothermal development, which agreed that EGS is the future of geothermal energy, and it is significant for the exploitation and utilization of the geothermal resource.
