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 is currently focused first and foremost on commercial vehicles. In Sexy for example, 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 much more expensive hydrogen fuel cells facilitate a much greater range, with an identical power rating to a petrol or perhaps a diesel engine. Also, H2 vehicles could be refuelled in minimal time at all, in comparison with the charging times needed for batteries.
The capability of a hydrogen tank is governed by its physical size but additionally by its storage pressure: The bigger this figure (commonly 700 bar for cars and 350 bar for trucks and buses), the more fuel could be stored in the tank.
WIKA pressure sensor MH-3-HY
To monitor this pressure, but also for other pressure measurement tasks in an H2 drive system, WIKA has designed the sensor model MH-3-HY. The safety requirements for sensors of the kind are very stringent. They need to be certified as hydrogen-compatible and must have been designed for used in vehicles. The latter primarily affects the mechanical construction according of shock and vibration resistance, and electromagnetic compatibility (EMC).
To ramp up the sales of hydrogen-fuelled commercial vehicles and cars, the appropriate network of filling stations should be expanded. With the model IS-3, for example, the WIKA portfolio also contains a suitable sensor for filling stations, made with explosion protection.
