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.Read more about the national hydrogen strategy
What is hydrogen?
Hydrogen (H2) 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 can be transported through our existing modern gas pipelines, minimising disruption and reducing the amount of expensive infrastructure needed to build a new separate hydrogen transmission network.
Green hydrogen is produced by using renewable electricity to split water into hydrogen and oxygen in a process known as electrolysis. As such, it is produced without the release of carbon dioxide (CO₂) and so is both a carbon free and renewable gas.
In 2021, the total wind energy generated in Ireland and Northern Ireland was 11,695 GWh, while 938 GWh of wind energy was dispatched down. This represents 7.4% of the total available wind energy in 2021. In Ireland, the dispatch-down energy from wind resources was 752 GWh. This is equivalent to 7.3% of the total available wind energy.

Given future plans to harness both on-shore and off-shore wind resources, this potential energy wastage could increase unless suitable storage solutions are used. Gas Networks Ireland has identified that green hydrogen production and integration with the gas network could provide a way to maximise Ireland’s renewable energy potential.
What role will green hydrogen play in Ireland's energy future?
Green hydrogen is well suited for storage, making it an attractive option to decarbonise energy systems and drive a cleaner energy future for Ireland and beyond. As Gas Networks Ireland works towards decarbonising our national gas infrastructure, hydrogen will play an integral role in Ireland’s energy future. Green hydrogen enables the optimisation and full exploitation of renewable electricity potential in Ireland by utilising excess generation that would otherwise be curtailed to produce green hydrogen for onward use on the gas network.
Hydrogen networks will play a key role in this future system, similar to the role played by the natural gas network today; supporting the deployment of increased renewable energy, providing resilience and flexibility to the electricity system, and serving the needs of high heat industries and businesses across the country. Ireland and the EU have committed themselves to achieving net zero emissions by 2050. 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.
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.Read more
The future hydrogen economy
The Irish gas network will play a central role in our future clean energy and hydrogen economies by connecting hydrogen production, storage and end-users within hydrogen clusters as they emerge at port locations and at other sites around the country.Read more
