Safe and Sustainable Testing of Hydrogen Powertrains

Abstract

Hydrogen-based powertrains are hopeful prospects in the development of climate-friendly transport systems of the future. Testing in a safe way is absolutely essential for the development and testing of hydrogen-based powertrains.

Our attention is to ensure sustainable testing.

Green hydrogen and green electricity, as well as feeding them back into the power grid, are important elements in the issue of sustainability. The production of green hydrogen through electrolysis is a goal we will achieve in 2024.

Safety is a priority issue, when testing with hydrogen. This is in our interest, but also in the interest of all our customers. A comprehensive safety package for the operation of hydrogen powertrains serves as a basis for this. This includes hazard assessment, fire and explosion protection documents, as well as a safety strategy.

The results of the risk assessment are the cornerstone for the safety concept.

The risk assessment reveals the hazards that can occur during hydrogen testing. With the help of various countermeasures, the probability of occurrence or risks of these events can be reduced.

These countermeasures have been worked out for a wide range of scenarios and include requirements for sensors, redundancies, as well as room air exchange rates and line evacuations.

The entire spectrum was then summarized in the safety strategy and is being implemented for all hydrogen test benches. This strategy relates to the test bench side. Special walls, explosion protection documents and ram protection are also installed for trailer stations in order to the safety of the hydrogen suplly process.
