CTM launches hydrogen: Cagliari among the leading cities in sustainable mobility
23 March 2026
Cagliari enters the new frontier of local public transport and becomes one of the first Italian cities to introduce hydrogen-powered buses into its fleet.
The three new buses, presented in Quartu Sant'Elena, are the first in Sardinia and form part of an investment plan of around 150 million euros with which CTM aims to achieve a fully zero-emission fleet.
The new vehicles will operate on suburban lines 9 (Cagliari – Decimomannu) and 19 (Quartu Sant'Elena – Assemini), routes characterised by longer distances, where high range and fast refuelling times allow continuous service without intermediate charging stops.
The vehicles, 12-metre Solaris Urbino Hydrogen buses powered by fuel cells, produce only water vapour with no polluting emissions, and can achieve a range of up to 600 kilometres.
Hydrogen thus forms part of a system based on an energy mix, the most effective solution for the future of public transport.
The fleet renewal programme continues: by September, 236 electric buses will be in service and, with the completion of the new charging infrastructure, CTM will have an increasingly sustainable and efficient public transport system, with the goal of reaching a fully zero-emission fleet by 2030.
