A net zero carbon gas network

Our vision is for Ireland's gas network to be net zero carbon by 2050. Gas is an essential part of Ireland’s pathway to 2050 and beyond.

Evolving the network

To evolve the gas network we are now blending renewable gas with natural gas. We are also developing the support network for Compressed Natural Gas and Bio-CNG in transport. In the longer term we will introduce hydrogen gas into the network and develop Carbon Capture & Storage (CCS) processes.

There are two core actions required

1. Inject renewable gas and hydrogen

We plan to inject 50% carbon neutral or zero carbon gases into the network. This will replace half of the natural gas required to meet consumer demand.

2. Capture and store CO₂ emissions

Natural gas will still be required to meet demand for power generation and large industry. The CO₂ emissions produced by using this natural gas will be captured and stored in a process called Carbon Capture and Storage (CCS).

Gases and gas technologies to deliver Ireland’s net zero carbon network

  • Renewable Gas

    It is net zero carbon, extremely versatile and fully compatible with the existing gas network infrastructure.

  • Compressed Natural Gas and Bio-CNG

    CNG is natural gas used in transport. Bio-CNG is compressed renewable gas used in transport.

  • Carbon Capture and Storage (CCS)

    Captures the emissions from natural gas power plants and large industry preventing emissions entering the atmosphere – the ‘abated’ natural gas is net zero carbon.

  • Hydrogen

    Produces zero CO₂ emissions when combusted and can be blended with natural gas or used in its pure form.

  • Natural Gas

    It emits 40% less CO₂ than coal and 22% less CO₂ than oil.

  • Power to Gas

    Uses renewable electricity to split water into hydrogen and oxygen.

The gas network can meet half the projected 2050 gas demand with net zero carbon gases (renewable gas & hydrogen) and by using carbon capture and storage to abate emissions from the remaining natural gas #Vision2050 #renewableenergy #CleanerEnergyFuture

Benefits of this approach

Least cost, least disruption

This is the least expensive and disruptive way to decarbonise home heating for those on, or near, the gas network. Decarbonising the electricity generation sector will be significantly cheaper using gas in combination with Carbon Capture and Storage.

More on decarbonising home heating

Immediate emissions reductions

Immediate emissions savings will be made by replacing peat, coal and oil with natural gas in electricity generation, heating and transport. Early progress ensures emissions savings accumulate and grow as we move toward 2050. Longer term, a total annual emission saving of at least 18.7 Mt CO₂ will be achieved across Ireland's economic sectors.

Energy security and flexibility

The flexibility and energy storage capacity of the gas network is unique. It ensures that heat is always available, and high levels of renewable energy can be accommodated on Ireland’s electricity grid. Gas with CCS will ensure that existing and new gas power plants can continue to provide flexible, secure and cost effective electricity generation.
