“The research project” HyTrain “was born against this background and from our responsibility to check the feasibility of the hydrogen variant for the Zillertalbahn 2020+. The lack of references and standards for limiting the procurement risk for this pioneering technology led to the need to put together a multidisciplinary consortium of research, development, planning and operations. With a view to other interested parties from the branch line sector and the resource situation in the Zillertal, we submitted “HyTrain” to the climate and energy fund via the flagship region WIVA P&G (hydrogen initiative flagship region Austria Power & Gas), “says Ernst Fleischhacker, Managing Director of the strategy and project development company FEN Sustain Systems GmbH (FEN Systems) based in Innsbruck.
