4 Energy and Water Nexus in the Alberta Context Water for Energy How much water consumption is for electricity? How much water consumption is for fuels? What reductions are possible? Energy for Water How much energy consumption is for water treatment? What reductions are possible?
5 Water Consumption for Electricity Plant Type Cooling Process Water Consumption, gal/MWh Natural Gas – Steam Turbine Open-loop100 - 250 Closed-loop160 - 690 Coal/ biomass – Steam Turbine Open-loop200 - 300 Closed-loop300 - 480 Nuclear Open-loop140- 400 Closed-loop590 - 850 Concentrated Solar Thermal Closed-loop740 - 890 Wind0 Sources: EPRI, USDOE and Argonne National Lab Open-loop Closed-loop
6 What about Carbon Capture 40 – 80% increase in water consumption Example, high rank coals Source: USDOE/NETL Report, “Cost & Performance Baseline for Fossil Energy Plants, May 2007” 0 40 80 120 Levelized Cost of Electricity (mills/kWh) IGCCNGCCPC-SubPC-Super No Capture IGCCNGCCPC-SubPC-Super No CaptureWith Capture
7 Water Consumption for Fuel Fuel or Feedstock Net Fresh Water Consumed, gal per gal of fuel Notes Gasoline (US Conventional) 3.4 – 6.6PADD II, III, and V combined Gasoline (Saudi Conventional) 2.8 – 5.8Dependent on age of well Gasoline (Oil Sands)2.6 – 6.2 Includes thermal recovery, upgrading and refining Corn Ethanol17 - 239 Variation caused by irrigation requirements Switchgrass ethanol2 – 9.8 Dependent on production technology Source: Argonne National Lab, 2011
8 Water Consumption per unit Energy and Water Use for Fuel Extraction & processing Source: Report to Congress on the Interdependency of Energy & Water, USDOE, 2006
9 Advanced Oil Sands Technologies to Decrease GHG Emissions and Water Use Decrease Fresh water Use Decreasing GHG Emissions SAGD, CSS Best-in-class SAGD Energy Efficiency SAGD, CSS Steam-solvent Electrical heating Combustion Non-aqueous Extraction Surface Minning Energy Efficiency refining, mining Current 5 - 10 years 10 - 20 years CCS
10 Examples of Reduced Energy and Reduced Water Recovery Processes Solvent Processes VAPEX Thermal Solvent Processes Steam Solvent Processes SAP ES-SAGD LASER Challenges: Depth, Reservoir Quality, Solvent Losses, Cost & Availability
11 Future Electrical Processes Electrical Processes Transfer of electrons between wells in situ EM field development, energy transfer and viscosity reduction Oil displacement & gravity drainage to production well ET-DSP ETI/ECP (GE Tech) Siemens Harris Challenges: Electricity source & cost, land disturbance, process efficiency

14 Impact of Increased Water Recycle on GHG Emissions *zero liquid discharge AI-EES Study: Assess impact of water recycling on energy use, waste generation Find “sweet” spots between water recycling & energy New technology opportunities AI-EES Study: Assess impact of water recycling on energy use, waste generation Find “sweet” spots between water recycling & energy New technology opportunities 9 companies, ADOE, AENV, ERCB
15 Commercially Proven Methods to Treat Produced Water from a Thermal in-situ Production Facility Produced Water Evaporation Warm Lime Softening
16 Minimize Water Use: Water Recycling Reduce fresh water use Use saline water as make-up Trade-off between energy and water: need new technologies
17 What About Membranes? ParameterCurrentWithin 10 years Power use, kWh/kgal~ $ 10~$ 7 Productivity, gal/day/membrane 6,500 – 12,50015, 000 – 25, 000 Useful life5 – 7 years10 – 12 years Key Issue: Deoiling efficiency
