Traditional vs Alternative Hydro Wave and Tidal Rivers and Streams Canals Industrial Water Nano-Hydro Inter-connection and Micro-Grids 3/22
Traditional: Based on head/height/pressure Need vertical drops and containment Dams and big pipes are main solutions Very small hydro possible but typically used in remote sites with natural flows, eg. Flooding Alternative: Based on water velocity Horizontal velocity: Like wind turbines Vertical velocity: Like heaving waves Power increases with cube of velocity Need < 4 knots or 2 m/sec flow for real power 4/22
5/25
Only a few places have adequate tidal flows for utility scale power CAPEX and O&M costs are insane Scotland is most promising global site 6/25
Only US NW Coast and W Europe have a few really good sites CAPEX and O&M costs are insane 7/25
Few rivers have speeds > 4 knots Obstacles include Floods, debris, access, many regulations, conflicting uses 8/25
How to tap the energy in these man-made waterfalls and canals?
Waterfall 2 25+ kw 5 w x 6 h (min); 6+ MGD Canal 1.5 18 kw 12 w x 6 h; 1.5+ m/s Same Advantages: Reliable, renewable power Fast installation (<8 hrs) Low maintenance Minimal site prep Minimal permitting Modular and scalable
Competitive before subsidies $4,000/kW $.04-.06 LCOE at 20-year lifetime ~ 6 year ROI at US avg $0.11/kWh
1. Cross-axis switchblade hydrokinetic rotor + 2. Low-speed Permanent Magnet generator + 3. Grid-tied inverters + 4. Hydrovolts sector focus = Affordable, small hydropower turbines to make clean power from water currents 12

CWU team visit to Hydrovolts in Seattle 3/6/2013 33
CWU project is on hold Hydrovolts is focused on obtaining new investment and on waterfall turbine installation. If granted, will demo two new canal turbines in Roza Canal in March with USBR. US Army Yakima Training Center is interested energy security from canal turbines Hydrovolts seeks funding and more partners to support its development and the future of new hydrokinetic power in the Valley and region. 3/6/2013 34
