Turning hydrogen into kilometres

Fuel cell electric vehicles (FCEV) powered by hydrogen are climate-friendly and also powerful. The growing demand for these zero-emission drives happens to be focused first and foremost on commercial vehicles. In Switzerland for instance, the ?H2 Mobility Initiative?, in collaboration with a major automobile manufacturer, aims to introduce 1,600 hydrogen-powered trucks to its roads by 2025. By 2040, 30,000 trucks, 40,000 buses and 80,000 taxis in South Korea could have H2 in their fuel tanks.
When compared to now widespread electric motors with batteries, the a lot more expensive hydrogen fuel cells facilitate a much greater range, with an identical power rating to a petrol or a diesel engine. Also, H2 vehicles could be refuelled in almost no time at all, in comparison with the charging times necessary for batteries.
The capacity of a hydrogen tank is governed by its physical size but also by its storage pressure: The higher this figure (commonly 700 bar for cars and 350 bar for trucks and buses), the more fuel can be stored in the tank.

To monitor this pressure, also for other pressure measurement tasks within an H2 drive system, WIKA has designed the sensor model MH-3-HY. The safety requirements for sensors of the kind have become stringent. They must be certified as hydrogen-compatible and must also have been created for use in vehicles. The latter primarily affects the mechanical construction according of shock and vibration resistance, and electromagnetic compatibility (EMC).
To crank up the sales of hydrogen-fuelled commercial vehicles and cars, the correct network of filling stations has to be expanded. With digital pressure gauge -3, for instance, the WIKA portfolio also includes the right sensor for filling stations, designed with explosion protection.
