Mahle Powertrain, the specialist engineering subsidiary of the Mahle Group, is expanding its Northampton facility to include a dedicated hydrogen powertrain testing capability.

The capacity to hold two tube-trailers on-site with rapid switch-over functionality between them will ensure a near-continuous supply of hydrogen.

In addition, upgraded engine dynamometers with a 900kW, 4,000Nm nominal capacity mean the centre will be placed to support the growing demand for hydrogen powertrain development as well as testing of both light and heavy-duty applications.

Simon Reader, Director of Global Engineering Services, Mahle Powertrain said: “Off-highway, heavy-duty and marine sectors are increasingly looking to hydrogen combustion engines as a way of decarbonising their emissions in areas where electrification isn’t suitable.”

The facility is already being used in the development of hydrogen fuel cell systems, hydrogen combustion engines and testing of hydrogen fuelled vehicles.

It will also soon begin work on the development of an H2-ICE concept that converts existing heavy-duty diesel engines to hydrogen combustion.

The facility’s supply side meticulously follows the BCGA (British Compressed Gases Association) guidance on the storage and handling of hydrogen. In addition, the individual test cells each feature a unique Mahle Powertrain-designed system for the monitoring and safe handling of any potential gas escape.

Reader added: “This expansion is in response to strong demand from our customers for this type of work. It equips our test cells with a dedicated hydrogen supply to create a facility that can perform rigorous testing on even the most heavy-duty engines and their increased weight and torque characteristics.”
