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.

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.

Hydrogen Research

Recent research conducted by Gas Networks Ireland shows existing gas appliances tested can be operated safely utilising blends of 20% hydrogen with natural gas, with a similar level of performance to meet customer requirements.
