b'28 Partner News Summer 2021EnterpriseThe ScottishRail integration of hydrogen traction technologyBased on a retired three-car Class 314 train, the Scottish hydrogen train conversion will Hydrogenfit an Arcola A-Drive fuel cell powertrain with hydrogen tanks and battery modules mounted under each end-coach. Train Project The A-Drives key components will be sized for test running on a defined route on the Boness and Kinneil Railway. Incorporating a 70kW fuel cell, hydrogen will be stored in composite cylinders at a Decarbonisingpressure of 350 bar with a capacity that is tailored to the requirements of the low speed, 100-mile demonstration route. Scotlands Railways Proven in several heavy-duty transport applications, the A-Drive powertrain platform will be extended to meet rail safety and compliance requirements, enabling Arcola to significantly reduce development time and cost to deliver a complete hydrogen traction solution in less than 10 months.Harnessing the strengths of batteries and hydrogen in a hybrid system, the electrical energy store comes from the hydrogen and fuel cell combination which increases the overall energy density.

Due to ambition to phase out diesel trains fromScotlands geographically diverse network,the tight schedule, Arcola is retaining the its network and deliver zero emissionconnecting communities and contributingtrains existing friction braking system in passenger railways by 2035. Large partsto a green economic recovery.the demonstration phase of the project.of the Scottish network have already been electrified but for several remote routes where electrification is not economically viable, hydrogen and battery technology offer complementary sources of traction.In December 2020, hydrogen fuel cell integrator Arcola Energy was appointed to lead a rail supply chain consortium to deliver a production-ready and safety certified hydrogen-powered train to demonstrate that hydrogen traction can be safely and effectively used as an alternative for the parts of the Scottish network where electrification is not practical or affordable. The project will see a retired class 314 electrical multiple unit (EMU) converted to hydrogen traction using Arcolas proven A-Drive fuel cell powertrain, with an overarching objective of creating opportunities for the Scottish rail supply chain through skills development and industrialisation of the technology.
