Revolution happening in geothermal energy industry Revolution happening in geothermal energy industry Document Transcript

  • Revolution happening in geothermal energy industry Geothermal energy supplies more than 10,000 MW to 24 countries worldwide and now produces enough electricity to meet the needs of 60 million people. It is considered possible to produce up to 8.3% of the total world electricity with geothermal resources, serving 17% of the world population. Thirty nine countries (located mostly in Africa, Central/South America, and the Pacific) can potentially obtain 100% of their electricity from geothermal resources (Dauncey, 2001). Already 24 countries are using geothermal energy source for producing electricity and another 22 countries will add to the list by 2010. In addition to large power generation, geothermal is also used for direct use purposes worldwide. In 2005, 72 countries reported using geothermal energy for direct heating, providing more than 16,000 MW of geothermal energy. Geothermal energy is used directly for a variety of purposes, including space heating, snow melting, aquaculture and more.Snapshots of status and potential of geothermal energy Renewable Capacity (GW) Market Size (billion $) Market Size Energy Growth Rate (%) Source 2008 Future Estimates 2008 Future Estimates Geothermal 14 20 7.5 13.1 8 According to market studies, investment in geothermal energy is growing at 24% a year. This exceptional investing growth rate is expected to continue - and increase even faster - for the foreseeable future. New Investments in Geothermal Energy ($ billions) 2004 2005 2006 2007 2008 2004-08 CAGR (%) 0.9 0.4 1.0 0.9 2.2 24Technology Advancement Estimated World Geothermal Electricity Potential with Present Technology with Technology Improvement
  • As seen from the chart above, with technology improvement, the total electicity generation potentialfrom geothermal increases 100%. The technology improvements are likely to come primarily frominnovative concepts such as enhanced geothermal.Until recently, geothermal power systems have only exploited resources where naturally occurringwater and rock porosity is sufficient to carry heat to the surface. However, the vast majority ofgeothermal energy within drilling reach is in dry and non-porous rock. Enhanced GeothermalSystems (EGS) are a new type of geothermal power technologies that do not require naturalconvective hydrothermal resources. EGS technologies "enhance" and/or create geothermalresources in this hot dry rock (HDR) through hydraulic stimulation.With technology advancement, it is estimated that the following countries could meet 100 percent ofelectricity demand with geothermal energy.

In those countries that have existing proven geothermal resources (such as the USA and Philippines), the governments have released mandates and programmes that show exceptional support for this renewable energy source. This support is in the form of tax breaks, grants, subsidies and more. How can individuals and entrepreneurs benefit from this dramatic opportunity? Geothermal energy industry presents attractive opportunities to a wide range of people, including investors and entrepreneurs.
  • Business opportunities by scale of investments required Scale of Type of OpportunityInvestment Consulting and installation for home-based geothermal systems Low Training people for geothermal heat pump installations Setting up medium scale geothermal plants Medium Setting up manufacturing plants for components and accessories for the geothermal energy industry Setting up large-scale geothermal equipment and components manufacturing plants Setting up large geothermal power plants or home-based geothermal installations High Involving in large-scale distribution of biofuels o Centralized grid-connected geothermal plants o Installing large-scale distributed (home or location-based) geothermal heat pumps
