Gas Networks Ireland is trialing an advanced composite pipeline technology that could lower emissions, improve network efficiency, and prepare the country's infrastructure for the transition to hydrogen. 

The state-owned company, which operates the national gas network, is collaborating with Purapipe International to test a patented pipeline material under real-world conditions.

The new pipeline, made from a proprietary composite, has the potential to reduce the carbon footprint of infrastructure projects compared to traditional materials, with its enhanced durability and efficiency expected to lead to long-term operational improvements.  

Initial off-grid testing is underway at Gas Networks Ireland's Network Innovation Centre in Dublin, in partnership with Murphy International.

The controlled environment allows engineers to rigorously evaluate the pipeline’s safety, integrity, and performance.  

With the results from the first phase of the pilot project expected in late 2026, this initial phase will help determine if the technology is suitable for broader deployment across the national network. 

According to Bobby Gleeson, chief operations officer at Gas Networks Ireland, the trial is part of the company's commitment to innovation and future-proofing the network. 

"By working with international partners like Purapipe, we can explore new technologies that could enhance the resilience of our network, reduce emissions, and ensure Ireland is ready to safely transport renewable gases such as hydrogen," Gleeson said in a statement.

Jesper Steen, CEO of Purapipe International, added that the project highlights the potential of the company’s technology to create more efficient and environmentally friendly infrastructure. 

The initiative is part of Gas Networks Ireland’s larger innovation program, which includes connecting biomethane producers and conducting hydrogen blending trials, all aimed at supporting Ireland's transition to a low-carbon economy.
