Turning hydrogen into kilometres

Fuel cell electric vehicles (FCEV) powered by hydrogen are climate-friendly and powerful. The growing demand for these zero-emission drives is currently focused first and foremost 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 2040, 30,000 trucks, 40,000 buses and 80,000 taxis in South Korea could have H2 within 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 a similar power rating to a petrol or a diesel engine. Also, H2 vehicles can be refuelled in minimal time at all, when compared to 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 higher this figure (commonly 700 bar for cars and 350 bar for trucks and buses), the more fuel could be stored in the tank.
pressure gauge MH-3-HY
To monitor this pressure, 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 this 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 according of shock and vibration resistance, and also electromagnetic compatibility (EMC).
To crank up the sales of hydrogen-fuelled commercial vehicles and cars, the appropriate network of filling stations has to be expanded. With the model IS-3, for example, the WIKA portfolio also includes the right sensor for filling stations, designed with explosion protection.
