The Causeway Project represents a significant step forward in delivering a sustainable alternative fuel for Irish transport. The Project will see the formation of a national Compressed Natural Gas (CNG) refuelling network, a renewable gas injection facility and the deployment of a fleet of CNG vehicles.

The Causeway Project Activities

The Causeway Project is delivered through 6 activities:

  1. Project Management
  2. Pilot CNG Network – 14 Fast Fill Refuelling Stations
  3. CNG Vehicles and Supports – CNG Vehicle Fund
  4. Renewable Gas Injection Facility
  5. System Operation & Data Analysis Study
  6. Communication & Dissemination


The Causeway Project is managed by Gas Networks Ireland together with the National University of Ireland Galway and runs from February 2016 to December 2020.

The Causeway Project is co-financed by the European Union’s Connecting Europe Facility (CEF). CEF is a transport and infrastructure program within the European Commission which focuses on sustainable, efficient, multi-modal transport across European key corridors.

Outcome: Sustainable alternative fuel for Ireland

The project will demonstrate the validity of CNG as a viable alternative to diesel for Ireland’s transport operators. Deployment mechanisms will be studied and disseminated across EU member states, informing further integration of CNG for Transport across Europe. This is in line with the vision of The Alternative Fuels Infrastructure Directive.
