Tuckerboot (hydrogen)
A H2Yacht is equipped with a fuel cell drive Tuckerboot. The two previously built boats serve as tour boats on the river Elbe and its tributaries around Hamburg.
Drive
The boat is driven through the polymer electrolyte fuel cells, which use as an oxidant and hydrogen as a reducing agent the oxygen from the air. The electric current thus produced is regulated by means of a DC-DC converter and drives the electric motors.
The required hydrogen is stored in high pressure tanks up to 350 bar on the boat. Since the fuel cell operates at relatively low pressure, a pressure reducing valve is installed in the hydrogen tanks.
The boat also carries with two backup batteries to still travel a certain distance, for example, in the case of fuel shortage can. In the DC-DC converter, a control unit is installed, which processes the thrust commands of the master and controls the engine accordingly.
Refueling
The two hydrogen tanks, each boat can be removed from the boat and be filled at hydrogen filling stations.
The tanks are equipped with a standard tank connection (TN -1), which is also compatible with the TK -15 and TK -16 - Tankanschlüsen the car hydrogen filling stations, and can be filled with 200 bar or 350 bar. You take a volume of either 26 l ( manageable by one person ) or 39 l (of two people to handle ).
The tanks can remain during refueling also inside the boat, but this is rarely possible, since there are hardly any hydrogen filling stations directly near water.
