Is district heating a cost-effective way to heat Irish buildings ? - Jason Mc Guire & Prof. Hannah Daly

Share of residential energy demand against the share of fossil fuel in DH in 2017 DH systems provide local employment & improved air quality. [...] The potential share of heat in the residential and services sector, which district heating networks could serve, and the potential share of surplus heat supply within the district heating networks DH was not a decarbonisation option in Ireland due to low modelling feasibility thresholds, which have now multiplied by 10. [...] Number of potential DH zones and the cumulative heat demand per group and region The heat demand density threshold is based on an even distribution of DH zones per heat density demand group. [...] Ireland’s sectoral and national carbon budgets, & climate targets (MtCO ) used in TIM Scenario No DH2 B Sectoral and national carbon budgets, and the net-zero target are core constraints in District Heating DH-30 30% heat market share & each scenario with no annual No annual growth capgrowth constraints Scenario DH-50 50% heat market share & C No annual growth cap DH-90 90% heat market share & No. [...] Page 13 Summary Conclusions Strengths Limitations Future Work • While not as significant • Irish energy sector • The cost of surplus • Account for new as electricity, DH is key coupling heat & the distance CHP as a supply in cost-effectively advancement.
