Renewable Gas

We’re working to decarbonise the gas network with renewable gases such as biomethane and green hydrogen.


Renewable gas, also known as biomethane, is a carbon-neutral gas made from farm and food waste through a process known as anaerobic digestion.

This renewable energy is structurally identical to natural gas and can be used in exactly the same way through the existing infrastructure, boilers and appliances, meaning homeowners and businesses will be able to transition to this sustainable energy source and play their part in progressing Ireland towards a cleaner energy future, without changing a thing.

The Biomethane Energy Report

Gas Networks Ireland has published the Biomethane Energy Report, a comprehensive study detailing the key findings from a national Request for Information process targeting biomethane producers.

GRAZE Gas Project and Mitchelstown Central Grid Injection

The Mitchelstown Central Grid Injection (CGI) facility will facilitate the injection of biomethane into Ireland’s transmission network. It is fully compatible with the existing national gas network, appliances, technologies and vehicles, and will ultimately replace natural gas to reduce emissions in heating, industry, transport and power generation, while also supporting the decarbonisation of the agri-food sector.


Green Hydrogen

Green hydrogen is a carbon free gas that can be produced from renewable electricity and is well suited for storage, making it an attractive option to decarbonise energy systems and drive a cleaner energy future for Ireland.

National Hydrogen Strategy

Gas Networks Ireland welcomes the publication of the National Hydrogen Strategy, an important milestone in the decarbonisation of the gas network in the journey to a net-zero energy system in Ireland by 2050.

Hydrogen Research and Projects

Hydrogen will be key to enabling the decarbonisation of sectors that are difficult to electrify such as high industrial heat, heavy transport and power generation.  

We believe that Ireland’s gas network will play a central role in Ireland’s energy future. To do this we are working on partner projects and conducting research to ensure that the existing gas network and gas appliances can be operated safely, while using green hydrogen to meet customer requirements.
