The first phase of the AERRL study on alternatives to fossil diesel use in railways is now at an end. The conclusions of the study, launched by the Association of European Rail Rolling Stock Lessors (AERRL), Akiem, Beacon and Cargounit, with support from Crédit Agricole CIB, ING, KfW IPEX-Bank and Societe Generale, show that the entire rail sector needs to design a common strategy to address the challenge of transitioning from fossil diesel. AERRL is proud to share an initial roadmap of technology alternatives for the years to 2050, based on results of a study conducted by eolos.
