The Causeway Project

Delivering sustainable transport for Ireland with a Compressed Natural Gas (CNG) refuelling network

Sustainable alternative fuel for Ireland

Gas Networks Ireland is leading a project called the Causeway Study, under which 14 high capacity fast-fill CNG stations, a single renewable gas injection point and a vehicle grant are being delivered. Successful delivery of these objectives will demonstrate the validity of CNG as a viable alternative to diesel in Ireland while also helping to meet Ireland’s requirements under the EU’s Alternative Fuels Infrastructure Directive.

Progress to date

To date, the Causeway Study has seen the development of a renewable gas injection facility, the deployment of a fleet of CNG vehicles and the rollout of 4 CNG stations at Circle K Dublin Port, Circle K Cashel, Circle K Ballysimon Road and Circle K Clonshaugh.

CNG stations

In December 2018, Gas Networks Ireland and Circle K launched Ireland’s first publicly accessible fast-fill CNG station at Circle K’s Dublin Port station. A second public CNG station at Circle K’s Cashel premises on the M8 motorway opened in July 2020. In 2021, new transport corridors became available for CNG vehicles travelling in Ireland with the opening of two additional Circle K stations at Ballysimon Road, County Limerick and Clonshaugh, County Dublin. 
 
Each station has the capacity to fill up to 50 HGVs a day, with each fill taking no more than five minutes. There are currently a further 7 public CNG stations progressing through the design, planning and construction project phases.

CNG Vehicle Fund

Gas Networks Ireland supported Irish businesses to transition to CNG through the delivery of a CNG Vehicle fund, making up to €20,000 available to businesses towards the purchase of a new CNG vehicle. The successful fund, which was designed to support the purchase of CNG powered commercial vehicles including trucks, buses and vans, was fully subscribed to. A new CNG Vehicle Grant Scheme is now available under the Green Connect Project.

Renewable gas injection facility

Gas Networks Ireland successfully injected locally produced renewable gas into the gas network for the first time at Ireland’s only purpose-built injection facility in Cush Co. Kildare. The dedicated renewable gas entry point in Cush commenced commercial flows in May 2020 and joined Corrib as the only indigenous gas source on Ireland’s network following the closure of the Kinsale Head gas field. Once flowing at maximum capacity, Cush can supply renewable gas to approximately 11,000 homes.
