Turning hydrogen into kilometres

Fuel cell electric vehicles (FCEV) powered by hydrogen are climate-friendly in addition to powerful. The growing demand for these zero-emission drives is currently focused first of all on commercial vehicles. In Switzerland for instance, the ?H2 Mobility Initiative?, in collaboration with a significant automobile manufacturer, aims to introduce 1,600 hydrogen-powered trucks to its roads by 2025. By Authoritative , 30,000 trucks, 40,000 buses and 80,000 taxis in South Korea could have H2 in their fuel tanks.
Compared to the now widespread electric motors with batteries, the much more expensive hydrogen fuel cells facilitate a much greater range, with a similar power rating to a petrol or a diesel engine. Also, H2 vehicles could be refuelled in minimal time at all, in comparison with the charging times necessary 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 can be stored in the tank.
WIKA pressure sensor MH-3-HY
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 this kind are very stringent. They need to be certified as hydrogen-compatible and must also have been created for used in vehicles. The latter primarily affects the mechanical construction according of shock and vibration resistance, in addition to 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 Save -3, for example, the WIKA portfolio also includes the right sensor for filling stations, designed with explosion protection.
