Bränsle för den moderna nationen Etanol och gengas i Sverige under mellankrigstiden och andra världskriget
Sammanfattning: This thesis investigate Swedish policy-making concerning promotion of wood gas and ethanol distilled from fermented sulphite lye as domestic fuel alternatives in the Interwar years and World War II. With a departure point in the theories of social constructions of technology (SCOT), the sociology of expectations and Thomas P. Hughe’s socio-technical systems I analyse the measures that were undertaken in these efforts, the arguments put forward for and against the ethanol and wood gas projects and how the efforts turned out. I also investigate how the interpretations of ethanol and wood gas as fuel alternatives changed from the Interwar period on through World War II and what consequences this had for ethanol and wood gas policy immediately after World War II. Source material includes Parliament and Government records, cabinet meeting files, governmental commissions, authority archives, technical evaluations and handbooks and scientific medical publications.Ethanol and wood gas were promoted from a nationalist vantage point. The Interwar debate was imbued with visions of national techno-scientific prowess in a perceived ongoing global contest for technological and scientific advancement, of which achieving autarky, self-sufficiency on important raw materials and industrial products, was an ideal for some. Ethanol and wood gas were also promoted as means for creating a lucrative new market for the forestry industry, which also held a prominent position in nationalist visions of technology. Expectations of a new war also motivated the promotion of ethanol and wood gas as national fuels. Measures for promotion included tax exemptions, sales guarantees and legislation for mandatory ethanol purchase for all petrol importing companies and gasifier loan funds. Political conflicts mainly centred around the principles of free trade as opposed to protectionism, proper use of tax funds and whether the potentials of the fuel alternatives were rhetorically exaggerated. During World War II ethanol and wood gas in particular served as important petrol surrogates. The increased wood gas use led to negative interpretations of wood gas a fuel alternative due to its hazardous, dirty and time-consuming maintenance and the changed driving behaviour it required from its users compared to petrol or ethanol fuelled automobiles. Compared to wood gas, ethanol was appreciated for its socio-technical similarities to petrol, but production was after the war deemed difficult to maintain during wartime. Whereas wood gas remained an important stand-by surrogate during the cold war, Swedish politicians lost interest in ethanol of the kind that was promoted in the Interwar years.
