Title: Geothermal Energy and the Great Basin Center for Geothermal Energy at UNR


1
Geothermal Energy and theGreat Basin Center for
Geothermal Energyat UNR
  • Lisa Shevenell, Director
  • Kwang Kim, Assistant Director
  • March 22, 2007
  • Senate Committee on Commerce and Labor

2
What is geothermal?
  • Areas where energy can be tapped from high
    temperature waters in the near-surface part of
    the Earths crust

Benefits of Geothermal Development
  • Diversifies economy
  • Creates jobs, particularly in rural NV
  • Provides clean, renewable power
  • Provides reliable, baseload power
  • Provides distributed power security
  • NV could be net exporter of power
  • Offsets fossil fuel emissions

7
The Environmental Impact
  • One Megawatt of Geothermal Energy will annually
    avoid()
  • 8,666 tons of CO2 / MW
  • 36.6 tons of SO2 / MW
  • 12.5 tons of NOx / MW
  • 11,000 gallons of water / MW
  • () Off setting a coal-fired power plant
    at 38 efficiency

Based on the International Energy
Agency (IEA)

Great Basin Center for Geothermal Energy
  • Initiated _at_ UNR via an earmark provided by
    Senator Reid in 2002
  • Conducting applied research in collaboration with
    industry
  • identify and evaluate new and emerging
    technologies
  • explore for and assess geothermal resources
  • Outreach/Training/Education
  • Provide needed and timely information
  • Have developed international reputation

10
Mission
  • The mission of the Great Basin Center for
    Geothermal Energy is to work in partnership with
    U. S. industry to establish geothermal energy as
    a sustainable, environmentally sound,
    economically competitive contributor to energy
    supply in the United States.

Opportunity
  • Nevada has a large geothermal resource base
  • UNR has a core group of qualified and experienced
    researchers in science and engineering
  • UNR has diverse engineering and geological
    science degree programs for undergraduate and
    graduate education

12
Considerable known geothermal resources in
Nevada 10 Power plant sites 14 Under
development 11 Direct use sites Many more
projected
13
Future Installations (from DOM)
  • 274 MW - 2006, installed
  • 60 MW - under construction
  • 55 MW - drilling
  • 70 MW - final permitting
  • 138 MW - exploration

14
Key Challenges/Goals
  • Locating productive resources (Developing
    exploration strategies)
  • Characterizing resources, reservoir
    management
  • Optimizing power conversion
  • Communicating results to stakeholders
  • Educating the next generation (collaborating
    with Sierra Pacific and Ormat)

15
Partnerships
  • GBCGE partnering with industry on several
    projects
  • Amp Resources Salt Wells
  • Nevada Geothermal Blue Mountain
  • Newcrest Resources, Inc. - Tungsten Mountain and
    McGinness Hills
  • Ormat Steamboat, Bradys, Desert Peak,
    Education/Training
  • Pyramid Lake Tribe on their property

16
Future Needs
  • Obstacles/barriers to future power plant
    installations
  • BLM permitting
  • Reducing risk of drilling (financing)
  • Stable funding
  • Develop curricula
  • Undergraduate (renewable minor) 3 colleges
  • Graduate already employing some
  • International workshops, short courses
