Decarbonising the gas network

•Download as PPTX, PDF•
•

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.

Decarbonising the gas network: getting to zero carbon emissions by 2050 Brendan Murphy
Ervia is a company of size and scale 1,700 employees We operate gas and water infrastructure and services 24/7 365 days a year 1.7m customers
Our Purpose To enhance the health and quality of life of the people of Ireland, protect our environment and enable economic development
Ireland’s Energy Mix Oil 57% Coal 2% Peat 1% Natural Gas 16% Electricity 19% Renewables 4% Wastes 1% Total Final Consumption Oil Coal Peat Natural Gas Electricity Renewables Wastes 4 • 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.

6 Carbon Capture & Storage
Gas is critical to Ireland’s electricity system 7
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
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
And CCS continues to develop 18 Large scale CCS facilities operating globally as of 2018. MT of CO2 has been captured since 1972. 23 MT in Norway. 230+ 40 Million tonnes of CO2 can be captured annually 6,500 KM of CO2 pipelines operating safely 2025 The United Kingdom created joint industry/gov working group to develop CCS by mid 2020s
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.
12 Biomethane
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 *Optimal use of biogas from waste streams: An assessment of the potential of biogas from digestion in the EU beyond 2020 (European Commission Report, 2016)
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:
15 Compressed Natural Gas Vehicles
• 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 16 0 500 1000 1500 2000 2500 Biomethane transport EV Subsidy required per t/CO2 abated
17 Hydrogen
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
19 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.
