Transition Roadmap for
Developing DHC in South Dublin
John O’ Shea
Energy Systems Analyst - Codema
Where to start? How? Why DH?
(Location, Mapping (Delivering Viable (The Big Opportunity)
& Stakeholders) Projects – Steps &
Support)
Why DH? – The Big
Opportunity
Carbon saving potential Renewable heat potential
Heat
4GDH CO2 saving
37%
potential in South
Dublin region
(250,000 tCO2/a) Transport
42%
Electricity
21%
SDCC Total
Emissions
(11,800 tCO2/a)
Why DH? – Not just a heating solution
Benefits recognised in EU &
national policy
Energy Efficiency Directive: Project Ireland 2040
Article 14 – Comprehensive DCCAE Climate Action Fund
assessment of potential for DHC
Climate Action Plan 2019:
Article 14(4) – Adequate
measures be taken to develop Action 70 – DH Policy framework
DH if cost effective Action 53 – Assessing financing
Recast Renewable Energy Action 133 – 3rd level campus DH
Directive:
Action 151 - Geothermal where
Acknowledges the contribution DH seen as key enabling
of DHC to increasing the share of infrastructure
renewable heat
Where to Start? - Location Heat Heat Physical Demand + Source - Barriers = Start Here
Heat Sources 17 Heat Source Types Investigated – Approx. 70 different data sources used
Heat Sources • Total heat capacity identified within SDCC = 493 MW • Total number of heat sources identified = 115 *Surface water could be over 10 times the listed capacity figure if mean flow was used
Heat Demand • Spatial Energy Demand Analysis (SEDA) • Future land use zones (SDZ, RES-N, REGEN)
Physical Obstacles These obstacles include; Infrastructure, Historical & architectural heritage sites, Habitat, Rivers & lakes.
Start Here Rank Name 1 Clonburris / Grange Castle 2 Clondalkin 3 Ballymount / Templeogue 4 Palmerstown 5 Lucan 6 Citywest 7 Rathcoole 8 Newcastle
Where to Start with Stakeholders? • What roles need to be filled • Further information on the methods of communication and common stakeholder questions can be found in the Transition Roadmap.
