There are ONLY Two Ways That We Can Reduce CO2 and Not Reduce Our Standard of Living

District Energy


The Fundamentals: Thermal vs. Electrical

Why District Energy : Denmark 1973 " 

Imported oil provided 94% of Denmark s energy supply; self-sufficiency 2%

" 

Oil crisis caused a severe shock to the economy which brought forward many ideas for energy conservation, fuel switching, and Combined Heat & Power (CHP)

" 

Large quantities of natural gas were discovered in the North Sea

" 

At the time, district heating supplied 30% of the Danish heating market; with 33% of heat produced by CHP plants

By 1980, energy planning at the Federal level lead to legislation & tax measures mandating a path to higher efficiency, cleaner fuels, the expansion of district energy systems, and the use of combined heat and power.


Why District Energy : Denmark 2000 " 

Dependence on imported oil – 2%

" 

Use of indigenous energy sources – 65% of total energy consumption

" 

District heating –50% (up from 30%)

" 

District heating produced by CHP plants – 64% (up from 33%)

" 

Renewable energy provides 25% of district energy fuel input

" 

25% of Denmark s total energy consumption fueled by natural gas

" 

60% of all Danish homes are heated by district energy

Benefits to Communities "   Long-term Community Investment "   Economic Development Tool "   Enhances Developer s Green Image "   Opportunity for CHP "   Fuel Flexibility & Diversity (and a bridge from nonrenewable to renewable fuels) "   Fuel Dollars Stay Within the Community "   Employment


Conventional Building Systems Approach

Natural Gas: Heating & domestic water

Electricity: Cooling & other loads

50% fuel conversion 10% transmission/ distribution losses

70%

COP 3.0


District Energy

" 

Boiler system efficiency increase; +diversity

" 

Chiller system efficiency increase; +diversity

" 

Combined heat & power

" 

Hot water thermal storage: recover excess heat from CHP operations, discharge at off-peak hours for heating

" 

Chilled water thermal storage: produce chilled water at night and discharge during peak hours.

" 

Absorption cooling: CHP heat produces cooling

" 

Bridge to renewable fuels (solar, biomass)

Energy Transfer Station


Conclusion

" 

Municipality Must be Involved to Have a Successful System

" 

Methodology Must be Developed to Ensure Maximum Connection

Rate " 

City Controlled Buildings Must be Connected ASAP

" 

Phase Build Out of System to Match Revenue

" 

Minimum Operations and Overheads for DE systems in Early Years


FINAL POINTS

§  If a Community does not have thermal energy infrastructure – it has not met the sustainability test. §  If a Province does not have a thermal energy infrastructure strategy, it is missing 50% of the energy equation.
