Meeting Objectives

• Develop wind/hydropower vision for hydrogen
  production
• Dialogue with stakeholders on the opportunities,
  barriers and priorities for wind/hydropower
  hydrogen production
• Provide feedback on modeling efforts
• Help define DOE role for renewable hydrogen
  production

Wind H2 Potential

• Current installed capacity 5 GW
• Potential installed capacity 3,250 GW (Class
  4)
• 1,100 GW needed to provide hydrogen for U.S.
  light duty fleet
• Class 3 wind development provides new
  opportunities

4
H2 and Hydropower

• 103.8 GW -- 8 to 12 percent of U.S. electrical
  generation
• Pacific Northwest, up to 70 percent of
  electricity is generated from hydropower
• Grid emissions trade-offs
• Near-term electricity source for distributed
  hydrogen

Renewable Electrolysis Challenges

• Delivery (electrons/hydrogen)
• Current technologies and system designs provide
  expensive hydrogen
• Bulk hydrogen storage
• Very low-cost electricity required

Technology Drivers
H2 Technology Drivers

• Next generation wind turbine designs
• Variable speed, reduced gearing
• Power control
• Low-cost, high efficiency electrolyzers
• Hybrid wind systems
• Power electronics
• Storage
• Advanced, lower cost TD (HVDC, etc)
• Bulk energy storage/distributed power
