Decarbonization Of Domestic Heating Systems In Ireland.pdf

The authors highlight the urgency of climate change action and the need to reduce greenhouse gas (GHG) emissions, particularly in the thermal energy sector, which accounts for a significant portion of Ireland's energy demand.

The study focuses on the town of Tralee as a case, with specific data on residential heating systems: 60% use oil-fired central heating, 20% rely on electricity, 10% use coal or other solid fuels, and 1% utilize biomass. Three scenarios are proposed for comparison:

- Base Case: Upgrading existing systems to expected efficiency levels.
- Scenario 1: Replacing all systems with individual biomass-fueled boilers.
- Scenario 2: Implementing a District Heating System (DHS) powered by biomass.

The research rationale underscores Ireland's EU-set renewable energy source heating and cooling (RES-H) target of 12% by 2020, emphasizing the need for significant progress in the renewable heat sector. The study also highlights Ireland's high oil dependency (49% of all energy use) and lack of fossil fuel resources, underscoring the importance of exploring alternative energy options.

Key considerations include:
- Renewability and Sustainability: Ensuring fuel stocks are locally available and produced.
- Local Economic Benefits: Increased cash flow within the community leading to job creation in various sectors.
- Social Gains: Improved air quality and potential tourism boost.

The authors advocate for a shift towards biomass-based systems, noting their potential to reduce GHG emissions, improve local economies, and create jobs, especially in areas hit hard by economic downturns.
