Accelera fuel cells power locomotive in HY2RAIL project

In partnership with the Austrian railway authority, ÖBB, recognised for managing one of Europe's most advanced railway systems, the HY2RAIL project demonstrates how fuel cells can sustainably meet the power needs of heavy-duty freight locomotives.

To power the locomotive, m.ZERO, an Austrian engineering consultancy, integrated Accelera fuel cell power modules into a strong 120 kW system. This customised system meets strict rail vehicle standards, including the European standard EN 61373, which outlines testing requirements for railway applications, focusing on shock and vibration.

Furthermore, m.ZERO oversaw the integration of all balance-of-plant components and interfaces in collaboration with Accelera. The fuel cell system was then combined with a ternary battery system to create a hybrid propulsion system that includes power electronics, on-board hydrogen storage technology, a vehicle control unit, and software. This integration was led by m.ZERO in partnership with project leaders Hy2RAIL.

ÖBB’s technical service arm, TrainTech, played a pivotal role in overseeing the railcar’s modernisation. The transformed locomotive was previously an OBB X534-type catenary construction and maintenance railcar, reliant on a diesel-electric propulsion system. Following installation of the new fuel cell electric system, it now runs emissions free.

“Expanding our fuel cell technology into locomotives for freight reinforces our standing as a premier fuel cell provider in the European market, particularly for the railway sector,” said Alison Trueblood, General Manager of Fuel Cell and Hydrogen Technologies at Accelera. “Alongside our experience with passenger trains, this project enhances our ability to support the dynamic rail market, further demonstrating the viability of hydrogen technology for zero-emissions heavy-duty transport.”

"We made the right decision with our choice of fuel cells for the project as Accelera's units are delivering exactly as specified,” said Herbert Wancura, CEO of m.ZERO. “Modernising to zero-emission technology isn't just feasible, it's an economically and environmentally savvy choice. We are ready to support rail OEMs in their zero-emission endeavours and eager to collaborate with Accelera again on any upcoming projects.”

The H2Rail project brought together the strengths and expertise of leading rail organisations and received co-financing from the Austrian Research Promotion Agency.
