As always, Scania’s work is based on a modular approach. In the four trucks deployed in ASKO’s operations, the internal combustion engine in the powertrain is replaced by an electric machine, powered by electricity from fuel cells fed with hydrogen and from rechargeable batteries. The rest of the powertrain is composed of the same standard components used in the hybrid trucks and buses that Scania already delivers.
To increase their range, these vehicles have been fitted with a hydrogen system, which converts the gas into electricity with just pure water as a waste product. This allows the vehicles to be used 24 hours a day whilst remaining quiet and clean.
Pierburg GmbH, a subsidiary of Rheinmetall Automotive AG, is applying its accumulated combustion engine expertise in pumps and valves to offer special products for fuel-cell vehicles. In addition to a leak-free control valve that is suitable for the specific requirements of fuel cells, two other products have been developed and occupy a special position in the market to date: a coolant pump and a hydrogen recirculation blower. Both are suitable for both low-voltage and high-voltage vehicle electrical systems with 400 and 800 volts.
The "H2 Kusatsu Farm" can stably supply hydrogen regardless of the weather by using two methods. The first one is to utilize water electrolysis unit that produces hydrogen by electrolyzing water using the power from solar panels. The other is to utilize compact hydrogen production equipment in combination with a gas reforming process with long and accumulated technology from "Ene-Farm", residential natural-gas type fuel cell.
Schaeffler has recognized the enormous potential of hydrogen technology as an energy carrier of the future and has developed key components for fuel cells and fuel cell stacks, so-called metallic bipolar plates.
