Heat Pump Systems

The technology is very matured and systems can be installed adopting the local temperature variations. According to the reports published in the World Geothermal Congress 2010, up to the year 2010 (ending December 2009) the installed capacity of GSHP in the world is 50583 MWt and the energy generated was 438071 TJyear (121696 GWhy: CF of 0.27). The country that has the highest installed capacity of GSHP is USA (12611 MWt) followed by China ( 8898 MWt). In China the amount of utilizable geothermal energy (for space cooling and heating) at shallow depths, according to a news published in "Renewable Energy World.com" in 2011, is equivalent to about 350 million tons of standard coal, which is equivalent to 2.8 million GWh of electricity. If this energy source is tapped, then this will reduce emission of 500 million tons of CO2 by avoiding to mine 250 million tons of coal. The extractable geothermal energy in China's 12 major geothermal provinces is equivalent to about 853 billion tons of standard coal that could generate seven billion GWh of electric power!!
