Pipeline Details Operator: ENURA S.p.A.[2] Owner: ENURA S.p.A.[2] Parent: Snam [55%], Gasdotti Italia S.p.A [45%][4] Capacity: Length: 573 km / 356.05 miles[5] Northern Section: 340 km[6] Southern Section: 231 km[7] Diameter: 10, 26, 8, 16, 6 inches[5] Cost: Estimated at €600 million[8] Status: Under construction[9] Start Year: 2025[5] Background 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.[10] [8] [11]
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.[5]
ENTSOG lists the project as "TRA-N-1194".[5] [12]
Sections of the project The Ministero della transizione ecologica splits the project into two sections: Methanisation Sardinia - Northern section[6] [7]
Northern Section The northern section is described by the Italian ministry as "the laying of two new DN 650 (26 ") pipelines from Palmas Arborea to Porto Torres, for a total of 126.495 km and a DN 400 (16") pipeline from Macomer to Olbia, with a length of 104.480 km and the laying of secondary pipelines functionally connected to the main lines with a length of approximately 110km."[6]
Included in this section are the following pipelines:[13]
a 26 inch diameter pipeline from Macomer to Porto Torres
an 8 inch diameter lateral pipeline to Alghero
an 8 inch diameter lateral pipeline to Sassari
a 16 inch diameter pipeline from Macomer to Olbia
a 6 inch diameter lateral pipeline to Theisi
a 6 inch diameter lateral pipeline to Suni
a 26 inch diameter pipeline from Palmas Arborea to Macomer
a 16 inch diameter lateral pipeline to Nuoro
a 16 inch diameter lateral pipeline to Siamanna
A map of the northern section can be found on the Ministero della transizione ecologica map viewer platform.[1] [13]

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.[8]
Incorporating Hydrogen In 2022, Italgas announced plans for an "end-to-end green hydrogen project" that will be integrated into the pipeline network being built in Sardinia. They plan to have the hydrogen produced in Sardinia through the use of energy blended with natural gas to make use of the pipelines built through the methanization project.[14]
Opposition Fridays For Future Cagliari, MetaNO, and other groups in Sardinia have organized events, written op-eds, and taken actions in opposition to the Methanization of Sardinia Project.[15] [16]
