Iberdrola has signed a memorandum of understanding with engineering consultants AECOM, regional sustainable project developers Ancitel Energia e Ambiente, and Cinque International, which has specialism in green hydrogen, to convert the 300 km Apennine railway in Italy to green hydrogen. Part of the line, which links Sansepolcro (Arezzo) and Sulmona (L’Aquila), is used by diesel locomotives which are approaching the end of their lives, and to convert the trains to run on hydrogen is considered far cheaper than to electrify the line. The MoU also encompasses “an evaluation of the technical viability of converting the Ferrovia dei Due Mare (Two Seas Railway) to green hydrogen, which will connect Fiumincino and Rome airports with San Benedetto del Tronto”. The projects are further examples of the potential of hydrogen as a future fuel/energy vector for heavy transport.
