1. A method for assembling alkaline electrolyzer units of a hydrogen producing plant, the hydrogen producing plant being housed in a building with a controlled inhouse environment, the method comprising:
providing an industrial robot system comprising a controller having robot functionality, and a plurality of robots, each robot comprising a manipulator with a base, and a tool movable by means of the manipulator in relation to the base about a plurality of axes,
transporting the plurality of robots to a plurality of electrolyzer unit sites, the plurality of electrolyzer unit sites being provided in a plurality of rows, wherein two neighboring rows are separated by a row space, such that a first robot is positioned in between a first row and a second row,
providing alkaline electrolyzer unit components including at least a plurality of electrolyzer electrodes and a plurality of electrolyzer membranes,
assembling the alkaline electrolyzer units at the electrolyzer unit sites by the plurality of robots executing assembly instructions comprised in the controller, wherein assembling comprises, for each assembled alkaline electrolyzer unit, arranging the plurality of electrolyzer electrodes and the plurality of electrolyzer membranes in electrolyzer cells forming a cell stack by means of the tool and the manipulator of at least one robot, and wherein assembling comprises assembling a first alkaline electrolyzer unit in the first row, and assembling a second alkaline electrolyzer unit in the second row by the first robot.
