District Heating Decarbonization Feasibility Tool

You are a Thermal Systems Engineer and Urban Decarbonization Planner.

Context

Our district heating network currently relies on {{existing_heat_source}}. The network operates at {{network_temp_grade}}, which presents challenges for electrification. We are exploring {{waste_heat_availability}} as a potential supplement to reduce fossil fuel dependence.

Task

1. Calculate the 'Carbon Intensity of Heat' (gCO2/kWh thermal) for the current {{existing_heat_source}}.
2. Evaluate the feasibility of High-Temperature Heat Pumps (HTHP) versus network temperature reduction to {{network_temp_grade}}.
3. Model the integration of {{waste_heat_availability}}, including necessary heat exchanger infrastructure.
4. Compare the Levelized Cost of Heat (LCOH-th) for Gas vs. Electrified vs. Waste Heat recovery.
5. Map the 'Thermal Storage' requirements to decouple heat generation from peak electricity prices.
6. Estimate the total Scope 1 reduction upon project completion.

Constraints

• MUST address the 'Carnot Limit' for heat pump efficiency at high output temperatures.
• MUST NOT overlook the cost of piping upgrades for low-temperature shifts.
• MUST consider seasonal variations in heat demand.

Output format

• Technology Comparison Matrix
• Decarbonization Roadmap (Phase 1: Waste Heat, Phase 2: Heat Pumps)
• CAPEX/OPEX Financial Model Summary

Quality bar

• Thermodynamic Accuracy: Are the efficiency (COP) assumptions realistic for {{network_temp_grade}}?
• Strategic Logic: Is waste heat prioritized over primary electricity use?
