IHA 2013 World Congress: IGA: Renewable systems: sharing experience

390

Published on

Dr Herman Ibrahim, Board Member National Energy Council, Indonesia, International Geothermal Association (IGA),

For many years, renewable energy systems were seen as dependent on non-renewable sources. Challenges of cost, variability, storage and ancillary services have been put forward as barriers to a renewable future. However, an increasing number of cases describe 100% renewable energy systems, utilizing the differentiated, but mutually supportive, characteristics of different renewable sources. Leading energy agencies will present the current status of the renewables sector, and representatives of each renewable energy technology will contribute on behalf of their constituencies.

Transcript of "IHA 2013 World Congress: IGA: Renewable systems: sharing experience"

  1. 1. Geothermal Energy SystemsHerman Darnel IbrahimBoard Member of International Geothermal AssociationBoard Member of DEN, the Indonesian National Energy CouncilPanel on Renewable SystemsIHA World Hydropower CongressKuching, 24 May 2013
  2. 2. Hydrothermal GeothermalEnergy source: Earth [magma]Technology: Dry Steam, Flash Steamand BinaryApplication: in 24 CountriesWorld Capacity: 12 GWYearly Production: 75 TWh1st Power Plant: 1904 [Italy]Geothermal Direct UseFor Heating and CoolingEnergy source: EarthTechnology: Down hole pump, Heatpump, Heat ExchangerApplication: in 78 CountriesWorld Capacity: 29 GWthYearly Production: 200 TWhGeothermal Production SystemsKuching, 24 May 2013 2IHA Congress: Geothermal System by HDI
  3. 3. Geothermal Power Plant is Steam Power Plant of which the natural steam isproduced from the earth.Geothermal Power Characteristics: Clean, No fuel combustion, steam is produced by drilling the earth. Renewable, used [condensed] steam is re-injected to the earth. Base load capability 85-90% Capacity Factor [not affected by seasons] Capacity per well up to 40 Megawatt Typical well capacity: 5 Megawatt Typical Well drilling success probability: 50-60% Typical drilling cost per well: USD 5 to 6 Million Typical Total Project plant investment cost: USD 3 to 4 Million per MegawattDevelopment Challenges High project risk [exploration] PPA and Exploration like Chicken and Egg: Utility prefer to sign PPA afterexploration [Feasibility Study], Developer “need” PPA before exploration.Geothermal Electricity SystemsKuching, 24 May 2013 3IHA Congress: Geothermal System by HDI
  4. 4. Technology Development: Resource assessment More competitive drilling technology Improving EGS [dry rock resources] technologyProjected Milestones In the period to 2030, rapid expansion of geothermal electricity and heatproduction will be dominated by deployment of conventional hightemperature hydrothermal resources driven by relatively attractiveeconomics. By 2050, geothermal electricity generation could reach 200 Gigawattproducing 1400 TWh per year. By 2050 , geothermal heat could contribute 5.8 EJ [~1600 TWh thermalenergy] annually.Policy makers, local authorities and utilities need to be more aware of thefull range of geothermal resources available, and of their possibleapplications.Geothermal Roadmap To 2050Kuching, 24 May 2013 4IHA Congress: Geothermal System by HDI
