By the late 1960s, petroleum had become the primary source of energy in the world. The thermal forces of petroleum and coal replaced the mechanical forces of water and wind. The time was ripe for the EU to strike up an 'energy transition' from the carbon economy of the twentieth century to the hydrogen economy of the twenty-first century. The biblical metaphor of the seven days of creation is helpful to emphasize three major features of the genesis of technoscientific objects such as fuel cells: First, they require a gradual process of individuation. Second, it may be a long, painstaking and possibly endless process. And third, a recurrent key issue lies in conflicting interactions between the fuel cell and its milieu. At the sunset of the seventh day, the 'hydrogen world' had not been created yet. In spite of reconfigurations at each stage, the fuel cell creature kept two constant features throughout the tentative creation of a 'hydrogen world'.
