The world’s first zero-emission pushboat, the Electra, was launched in Berlin at the end of May. It is equipped with hydrogen fuel cells with a total capacity of 300 kW, photovoltaic panels with a total capacity of 2.5 kW-peak, and lithium-ion batteries (with a capacity of 116 kWh and 1,160 kWh, respectively). It will be used for transporting the Ursus barge, which is supposed to carry industrial cargo between Berlin and Hamburg.
