District Energy System Four scenarios (2.1-5.2 MW) $128-154/MWh
Decentralized Boilers $110-127/MWh Still dependent upon fuel imports
Low cost firewood Pellet boilers/DES higher cost Firewood boilers may be best option
Electricity is subsidized Residents pay $0.13/kWh; diesel cost is $0.40/kWh BC Hydro has incentive to reduce electrical space and
hot water heating: 5-7 year payback

Background on Canada’s Oil Sands
22
• Canada has the world’s 3rd largest oil reserves: 173 B bbl
• Ultimate potential is 315 B bbl (larger than Saudi reserves)
• Oil sands are 97% of Canada’s proven reserves
• Production: 2.3 M bpd in 2014 to 4 M bpd in 2024 World = 94 M bpd
• CDN Economic impact 2010 to 2035 forecast: $2.1 trillion
• Contribute >$750 B to government revenue (2010-2035)
• 2014: 0.5 EJ/yr of natural gas

Background on Canada’s Oil Sands
23
• Surface mining & In situ recovery options
• SAGD is most common In situ method
• Surface mining = more water challenges; lower GHGs
• Only 20% of oil sands recoverable using surface mining
• ~50% of recovery is In situ and main source of growth
• ~55% of bitumen upgraded to synthetic crude oil in Alberta but forecast to drop to 20% by 2026
• Bitumen must be blended with a diluent (e.g., natural gas condensate) to pipeline

Alternative Approach to Liquid Biofuels
Cellulosic Ethanol Thermal Bioenergy & Biohydrogen in Oil Sands
300 L EtOH/bdt (200 L gasoline) 1450 L SCO/bdt (gasoline cut = 650 L)
CHP for internal demand CHP for In situ recovery
33% energy yield to ethanol 80% (or more) thermal efficiency
Electricity exports? Displace coal vs. gas?
80% GHG ↓ from CDN baseline 90% GHG ↓ Well-to-Refinery
↓ ~0.5 t CO2e/bdt Thermal: ↓ ~1.0 t CO2e/bdt
• Low carbon fuel standard: reduce life cycle GHG emissions by 20% from 100 g CO2e/MJ fuel baseline from 1 BL
• Cellulosic ethanol: 1.1 M bdt
• Thermal bioenergy: 500 k bdt

Biosteam for Manufacturing?
• Eneco to provide ‘biosteam’ for Delfzijl Chemie Park in the Netherlands (via CHP generation)
• AkzoNobel Specialty Chemicals is main tenant
• Retrofit to existing biomass power plant
• Site accounts for 10% of Dutch chemical production

Renewable Natural Gas (Biomethane)
• Most likely bioheat for detached homes in cities with natural gas
• Agriculture and municipal feedstocks will dominate
• Greatest potential volume is forest feedstocks
• $12-15/GJ for ag/municipal; double that for forest
• In Ontario, much lower cost than electric heat
• Competitor is electricity, NOT natural gas
• Europe = government-led approach
• Canada = utility-led approach
• Biggest hurdle at present is regulatory situation
• Regulated utilities limited by the OEB
