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 happens to be focused first and foremost on commercial vehicles. In Profit 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 within 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 perhaps a diesel engine. Also, H2 vehicles can be refuelled in almost no time at all, in comparison with the charging times needed 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 could be stored in the tank.
WIKA pressure sensor 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 the kind are very stringent. They must be certified as hydrogen-compatible and must also have been created for used in vehicles. The latter primarily affects the mechanical construction in respect of shock and vibration resistance, in addition to electromagnetic compatibility (EMC).
To crank up Security 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.
