Turning hydrogen into kilometres

Fuel cell electric vehicles (FCEV) powered by hydrogen are climate-friendly together with powerful. The growing demand for these zero-emission drives happens to be focused first and foremost on commercial vehicles. In Switzerland for example, 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 2040, 30,000 trucks, 40,000 buses and 80,000 taxis in South Korea could have H2 within 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 perhaps a diesel engine. Also, Pitfall 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 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 have become stringent. They need to be certified as hydrogen-compatible and must have been created for used in vehicles. The latter primarily affects the mechanical construction in respect of shock and vibration resistance, along with electromagnetic compatibility (EMC).
To crank up the sales of hydrogen-fuelled commercial vehicles and cars, the correct network of filling stations must be expanded. With the model IS-3, for example, the WIKA portfolio also includes the right sensor for filling stations, made with explosion protection.
