3 Traditional vs Alternative Hydro Wave and Tidal Rivers and Streams Canals Industrial Water Nano-Hydro Inter-connection and Micro-Grids 3/22

4 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 5/25

6 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

7 Only US NW Coast and W Europe have a few really good sites CAPEX and O&M costs are insane 7/25

8 Few rivers have speeds > 4 knots Obstacles include Floods, debris, access, many regulations, conflicting uses 8/25

9 How to tap the energy in these man-made waterfalls and canals?

10 Waterfall kw 5 w x 6 h (min); 6+ MGD Canal 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

11 Competitive before subsidies $4,000/kW $ LCOE at 20-year lifetime ~ 6 year ROI at US avg $0.11/kWh

12 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

13 TM High-speed channels Spillways and waterfalls Slow steady channels All channels and speeds 13

14 TM Submerged or surface Floats in place Operates in slow currents Easy to make, install, repair Range of sizes, blades 14

15 Has floating end caps Held in place with ropes Can float or rest on base Power from generators goes up anchor line to load or grid on shore Range of sizes, blades 15

16 Tested by US Navy Power up to several US homes Power for pumps and irrigation Backup and emergency power Hydrovolts turbine in US Navy test tank 16

17 USBR operates the canal It runs 11 months/year Hydrovolts has License Agreement to use as demo site

32 Stackable Permanent Magnet Generator for Micro Hydro Stator has coils Rotor has magnets Stackable design fits most sites 3/6/

33 CWU team visit to Hydrovolts in Seattle 3/6/

34 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/

37 US Bureau of Reclamation Innovate Washington Impact Washington McKinstry Co Potential Partners: US Army Corps of Engineers Fort Lewis Yakima Training Center 37/22

38 New Energy for Development Create new local economies Create new agriculture lands Change the Water Paradigm Now, move water to make power Change the fundamentals of canal design A New Industrial Sector Make turbines like cars in factories close to the customers New basic manufacturing jobs supporting clean energy 38/25

39 Provide rate parity with solar! Partner with Federal Agencies USBR, USACE, Army, Energy Support energy resource assessments Support CWU and our Yakima project 39/22

40 Mass-scale Micro-Hydro is finally profitable 100+ GW of power unleashed Water Transport = Clean Energy Change the Canal Paradigm A World of New Applications Where the water flows, energy grows Burt Hamner, Founder & Director 40/25
