In-Stream Hydrokinetic Turbine in Ruby, Alaska Alaska Federation of Natives Anchorage, AK October 24, 2008 Brian Hirsch, Ph.D. Energy Program Manager Yukon River Watershed YRITWC •66 Tribes & First Nations •Treaty – based •VISION: Drink water directly from River within 50 years •Clean water needs clean energy •Municipalities as observer/participants Definition • Hydrokinetic: “Moving Water” (no dams!) – Includes both Ocean (tidal) and River (in-stream) Hydrokinetic Variations Challenges/Considerations » River “Trash” (Debris) » Ice & break-up » Silt » Water Speed » Anchoring » Power Delivery to Shore » Navigable Waters » Fish » Permitting Lessons Learned • It Works! (“proof of concept”): – Produces power; diversion boom; grid integration • Performance improvements/cost reduction: – Better current; anchoring system; turbine design for lower current; anchor line debris • To Be Determined: – Fish impacts; permitting; data monitoring & ongoing resource assessment The Future Mobility Scale it Up!
