BackgroundThis paper is based on an issue raised by the organization Energigas Sverige, which together with the Ministry of Finance has posed the question about the fiscal impact of an increase in biogas production. Since the fiscal effects of an increased biogas production are both positive and negative, due to reduced use of fossil fuels, we want to investigate this further.PurposeThe purpose is to describe and explain the obtained fiscal impacts of an increased biogas production and based on our problem: ?What are the obtained fiscal effects caused by an increase in biogas production?? we could see the following fiscal effects: positive impact on employment, increased revenues of social security contributions and income taxes, reduced unemployment costs and reduced tax revenues on fossil fuels. These effects are summarized in a negative tax revenue of 2,6 billion SEK. Along the summarized negative effect we also accepted one of the two prepared hypotheses, which stated that an increase in biogas production leads to a negative fiscal impact. Design/Methodology/ApproachWe have chosen to work from an Anglo-Saxon scientific tradition and furthermore, we have a positivistic approach when we want to explain the relationship between cause and effect of an increase in biogas production and the following fiscal impacts.

Osynkroniserade processer samt för små gasklockor hos SSAB EMEA Luleå orsakar fackling av energirik gas och andra problem som exempelvis svängande värmevärde på blandgas. Med hjälp av waveletanalys, korskorrelation och autokorrelation har dynamiken i systemet Energigaser kartlagts och analyserats. Utifrån det framarbetade resultatet har även åtgärdsförslag tagits fram.Resultatet visar bland annat på att masugnsgasen har regelbundna svängningar med 30 minuters intervall. Detta påverkar blandgasen som också svänger med 30 minuters intervall men fördröjt jämfört masugnsgasen. Detta beteende orsakar onödig fackling av masugnsgas om nivån i blandgasklockan är för hög.
