Decarbonising Electricity Generation with CCS – Ireland needs ‘Zero Emission Firm Power’ No credible alternatives to Gas+CCS – AT SCALE û Nuclear - Not legally allowed û Hydro - Lack of resource û Biomass - Sustainability??? û Batteries - Scale unachievable û Electrical I/C - Unsuitable for Security of Supply Long periods with very little wind No other technology visible today to provide long-term, low-carbon peak supply – securely Long periods with very little wind 5

What is Carbon Capture and Storage? Exhaust gas CO 2 CO 2 Compression CO 2 underground Gas-fired CCGT Carbon Capture Transportation power plant and Conditioning storage Unit CO 2 is The captured The CO 2 is Existing or new 90% of CO 2 transported power plant CO 2 is injected into the separated from through both compressed and depleted gas exhaust gas from onshore and dried field for the power plant offshore gas permanent pipelines to a storage depleted gas field 7

Global CCS Status Large scale CCS facilities 18 230+ operating globally as of 2019. MT of CO 2 Million tonnes of CO 2 can 40 has been be captured annually captured since 1972. KM of CO 2 pipelines 6,500 23 MT in operating safely Norway. 0 The United Kingdom created joint 2025 industry/gov working group to develop CCS by mid 2020s 8

Global CCS Status

Experts agree on need for CCS Limiting global warming to 1.5 degrees will require ‘the use of negative emissions technology’ Bio Energy CCS will be critical 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 The UK Committee on Climate Change’s Net -Zero report (May 2019) states “CCS is a necessity not an option”.

Proximity of power plants and refinery to where offshore pipe comes onshore Aghada CCGT • The 56km offshore gas pipeline comes Inch Terminal – link Irving Oil to offshore gas Refinery ashore at Inch infrastructure Terminal. Whitegate CCGT • All key infrastructure for CCS is located within a few kms of each other. 17

KPMG Report for the UK Energy Networks Association – decarbonising heating Evolution of Gas Diversified Energy Networks Sources - Gas and hydrogen for heating - Different technologies in different areas (Municipal model) - Carbon Capture & storage £156 - £188 bn £104 - £122 bn Electric Future Prosumer - Switch to electric heating systems - Self-generating heating - Gas network no longer used Gas network no longer used £274 - £318 bn £251 - £289 bn

Hydrogen production Steam methane reformer Electrolysis • A proven commercial technology in use since • Carbon free if renewable electricity used. 1960’s. Lowest cost and dominates production. • Potential solution for electricity industry’s storage • Natural gas commonly used as a feedstock as dilemma. being low sulphur little pre-treatment is needed • Currently higher cost due to grid electricity costs. and it is already compressed. • Used in smaller scale production including service • 250MW unit is a typical size. station in demonstration projects. • Output >99.9% purity. • Up to 100MW available • Efficiency 70%-80% HHV • Output >99.999% purity. Suitable for CCS to be added . • Efficiency 70% HHV. • 30

Most EU countries are active in hydrogen demonstration activity Ireland has the opportunity to Ireland has the opportunity to EU Power to gas projects EU Power to gas projects participate but has not done so participate but has not done so EU allowable blend percentages EU allowable blend percentages 31 31 31 31

Typical storage capacities and time scales of different network scale technologies Electricity storage will require several technologies to overcome the volatility of renewable generation. Power to gas may play a role in large scale long term energy storage well beyond the capabilities of batteries. 32

A future international trade in hydrogen? • Hydrogen may be produced more economically elsewhere. – Countries with CCS facilities may produce hydrogen from SMR and export i.e. Norway – Countries and areas with high wind resources may have dedicated hydrogen production from renewables i.e. Dogger bank island proposal – Countries with large solar potential may use emerging technologies i.e. North Africa, Australia to Japan • Hydrogen may be shipped – In liquid form at very low temperatures – Contained within ammonia at -30C at atmospheric pressure • Hydrogen may be transported by pipelines – There is circa 3,000 km of hydrogen transmission pipelines in both Europe and the US 33
