Methanization of Sardinia Project is a proposed natural gas pipeline system on the island of Sardinia in Italy.


The proposed pipeline would run north across Sardinia from Cagliari to Porto Torres, with branch pipelines leading off the main pipeline to Carbonia, Nuoro, Bosa and Olbia.[1][2][3]

Pipeline Details

  • Owner: ENURA S.p.A.[2]
  • Capacity:
  • Length: 573 km / 356.05 miles[4]
  • Diameter: 10, 26, 8, 16, 6 inches[4]
  • Cost: Estimated at €600 million[5]
  • Status: Proposed[4]
  • Start Year: 2025[4]


In May 2019, a new project for a 573 kilometre gas pipeline in Sardinia was presented by Enura, a joint venture between Snam - Italy’s leading gas transport company - and Società Gasdotti Italia. The project is being backed by the regional government of Sardinia.[6] The first, southern portion of the project from Cagliari to Oristana received clearance from Italy’s environment ministry in the summer of 2020, but has not yet been authorised by the national economic development ministry.[5] In addition to the pipeline, a network of regasification plants, coastal depots and city grids would create the capacity to transport up to 1.8 billion cubic meters of gas across Sardinia. The project costs of approximately €600 million look likely to be paid for by taxpayers through levies in their future energy bills. Arera, the state regulator for the energy sector, has pointed out that the costs can be spread across Italy as whole but only if a special government bill is introduced. Otherwise, Sardinian citizens alone will have to pay for the project.[7]

According to the SNAM "Ten-year development plan of the natural gas transmission network 2017 – 2026," the Methanization of Sardinia project consists of "a main backbone belonging to the National Network for a length of approximately 380 km and having a diameter of DN650 / DN400 and the pipelines belonging to the Regional Network for about 190 km with diameter DN400 / DN150 that will allow to reach the main market areas of the Region." Implementation of the project was expected by 2021, but the European Network of Transmission System Operators for Gas (ENTSOG) expects the project to commence operation in 2025.[4]

ENTSOG lists the project as "TRA-N-1194".[4]

The renewable energy alternative for Sardinia

Rather than progressing with the island's gasification via the pipeline project, clean energy advocates are proposing that Sardinia's excellent wind (onshore and offshore) and solar resources should be developed further. A study published in August 2020 by the Politecnico di Milano university and commissioned by WWF found that 100% of Sardinia’s energy needs could be met by renewable energy by 2050. The study projects that this would require Sardinia's total wind and solar capacity to rise by approximately ten times the current level, to roughly 20 gigawatts.[5]
