The government has come under pressure to stop the imminent decommissioning of the Kinsale gas pipeline and the Inch onshore terminal in County Cork.
Fine Gael TD David Stanton called for urgent action due to current pressures on gas supplies in Europe and a lack of alternatives in Ireland.
Deputy Stanton said: "Due to the current pressures on gas supplies in Europe, no gas storage infrastructure in Ireland and a reliance on the gas interconnector to Scotland, I am greatly concerned that we have no contingency if the situation deteriorates further.
"We depend on gas to cook our food, heat our homes, power industry, and generate a lot of our electricity. Many recent reports have highlighted serious concerns regarding the country's almost total reliance on gas imports arriving through the pipeline from Moffat in Scotland."
He continued: "I see this pipeline and the terminal as critical pieces of national infrastructure which could be used to facilitate a Floating Storage and Regasification Unit (FSRU) for non-fracked LNG imports. These imports would provide a consistent, and what I believe to be necessary, backup support to ensure security of supply in our transition to renewables.
"This pipeline and the associated infrastructure remain in place as the Kinsale and Seven Heads gas fields go through the decommissioning process. I would ask that the decommissioning of this infrastructure be stopped and the possibility of affixing an offshore FSRU be closely examined. We need to look at the potential benefits to further diversifying the country's gas supply sources.
"This would mean that we could move relatively quickly to ensure an alternative method of satisfying security of gas supply in the event that supplies through the gas interconnector to Scotland were unable to be fulfilled."
