Project objectives:
The use of hydrogen engines is an indispensable part of the energy transition and can represent a cost-effective and reliable alternative to fuel cell vehicles in many areas of application. However, as a gaseous and carbon-free fuel, hydrogen has very poor lubricating properties. This results in a number of problems, such as the high stress on the lubricating oil due to water as a combustion product, increased risk of corrosion and increased wear.
In order to avoid performance variations and achieve an optimum lubricating oil selection, the aim of the joint project with the Chair of Technical Thermodynamics at the University of Rostock is to simulate the lubricating oil stress in hydrogen operation as realistically and systematically as possible in the laboratory and to document and evaluate the observed lubricating oil changes. This will mainly be done using fully formulated engine oils. However, model oils (pure base oils, base oils specially doped with individual additives) will also be used for certain questions. Based on the data collected, a catalogue of criteria for lubricating oils in hydrogen applications will be proposed and new product developments initiated. The active focus here is on the innovative use of bio-based or CO2-based base oils in order to improve the aspect of sustainability in the lubricant sector as well.
