Five cylinder pressure tanks with a volume of 1,560 are placed on the roof of the vehicle in the rear area. At a pressure of 350 bar and a density of about 24 kilograms of hydrogen per cubic meter, the tank’s capacity will be 37.5 kilograms.
For comparison: Solaris provides a range of 350 kilometers for the Urbino 12 hydrogen with a comparable tank size. So either Karsan is much more efficient or the manufacturer has decided in favor of a 700-bar system – in which case, at a density of 40 kilograms of hydrogen per cubic meter, 62 kilograms can fit into the tank.
The E-drive is supposed to be a very quiet hub motor, its battery running on lithium titanate cell chemicals. The hub motor allows for a very flat and roomy interior. For the body, Karsan offers a choice of two or three doors. The hydrogen e-ATA can carry up to 95 passengers, 40 of whom are seats.
This model is equipped with factory air suspension and can be ordered with an optional assist system and a digital mirror replacement system. Karsan says it uses proven components from the European bus supply industry.
The hydrogen e-ATA, which has now been presented at IAA Transportation in Hanover, is based on the battery-electric drive e-ATA that was launched a year ago. It is available as a solo bus of ten or twelve meters in length (with a battery capacity of up to 300 or 450 kWh) and also as an 18 meter articulated bus.
Here, up to 600 kWh can be installed, and the maximum power of the articulated bus is twice as high at 500 kW thanks to the two driven axles. It is not yet known whether fuel cell drive will also be offered on the articulated bus. Solaris presented the 18-meter model with fuel cells shortly before the trade show in Hanover.
