Hybrid Energy Systems: An Integrated Energy System Scheme
Sustainability:
• Economic
• Environmental
• Social
Results
• Case 1: High gas prices (6.2%/yr) with an imposed carbon tax
• Case 2: Low gas prices (3%/yr) with an imposed carbon tax
• Case 3: High gas prices (6.2%/yr) without an imposed carbon tax

• Two heat sources • Two uses of low
temperature heat • Three forms of storage Effective configurations may utilize subset of these.
Features: • A better DG
• At dist sub • 10-100MW
• Modular • built quickly • region-specific
configurations • Efficient • Flexible
• fast • storage
