This document discusses decarbonizing Ireland's gas network by 2050. It notes that natural gas currently meets 16% of Ireland's energy needs. The document outlines a path to a zero carbon gas network by 2050 through increasing renewable gases like biomethane and hydrogen, and using carbon capture and storage technology with natural gas. It argues gas will continue to be important for electricity generation and replacing fossil fuels in heating and transport. The document maintains decarbonizing the gas network requires supporting technologies like carbon capture and storage, as well as utilizing Ireland's existing gas infrastructure and renewable resources like biomethane.

• Ireland’s dependency on oil must change if
we are to meet climate targets.
• Natural gas meets 16% of final
consumption and generates over 50% of
the electricity.
• Gas network can be decarbonised and can
replace fossil fuels in electricity generation,
home heating and transport.

8. Decarbonising Electricity Generation – Ireland needs CCS
8
June 2018 – Power Generation by Fuel Type
No other technology visible today to provide
long-term, low-carbon peak supply - securely
No credible alternatives to Gas+CCS – AT SCALE
Nuclear - Not legally allowed
Hydro - Lack of resource
Biomass - Unsustainable
Batteries - Scale unachievable
Electrical I/C - Inadequate & unreliable
Long periods with very
little wind
9. Experts agree on need for CCS
The UK Government should not plan to meet the
2050 target without CCS
To stay ‘well below 2 degrees’ CCS would provide
32% of global emission reductions
Limiting global warming to 1.5 degrees will require
‘the use of negative emissions technology’ Bio
Energy CCS will be critical
10. And CCS continues to develop

11. Carbon Capture & Storage
• CCS - carbon neutral power
for Ireland
• Could capture & store 2.5
million tonnes of CO2 pa.
• Potential for export of CO2
• CCS needs to be supported,
similar to wind energy.
13. Biomethane: Ireland has a significant opportunity
13
• Highest resource
potential in the European
Union
• Offers opportunity for
farmers to diversify
• Enhances Ireland’s
Security of Supply
• Needs to be supported

14. Utilising biomethane to decarbonise home heating
14
Least cost and least disruption
to the homeowners
Avoids expenditure on ‘deep’
retrofits of over €50bn
Supports Ireland’s indigenous
renewable gas sector
Increased utilisation of an
existing state asset worth over
€2.6bn
Decarbonising homes utilising
biomethane offers:
16. • Over 25m CNG vehicles globally
• Min network of 70 CNG stations across Ireland
14 stations by 2020
• Transition from natural to renewable gas
• Initial CO2 reduction of up to 22%
• 99% less Particulate Matter
Biomethane can also decarbonise transport

18. Hydrogen will also play a key role – UK leading the way
18
• Converting North of England (3.7m
connections) to a hydrogen network. Potential
to decarbonise 70% of homes by 2050 in UK.
• Converting industrial demand in Liverpool &
Manchester to hydrogen including a
residential blend
• Hydrogen blend trial on a private network

Key Messages
• The Irish Gas Network can be carbon neutral by 2050 with
the right supports for CCS, Biomethane and Hydrogen
• The consumer needs to be at the heart of the transition.
Least cost and least disruptive technologies will be favoured
by consumers.
• To achieve decarbonisation Ireland will need to utilise all its
assets. Electricity and gas networks will be critical.
