Skogliga biobränslens roll i Stockholm Exergis framtida strategi / The role of woody biomass in the future strategy of Stockholm Exergi

Danielsson, Ellinor, Ekman, Jenny January 2021 (has links)
Studien syftade till att ge en rekommendation angående hur fjärrvärmebolaget Stockholm Exergi bör utforma sin framtida strategi beträffande fasta oförädlade skogliga biobräanslen. Genom litteraturstudier och intervjuer utreddes dessa bränslens konkurrenskraft utifrån perspektiven klimatneutralitet, politiska direktiv och styrmedel, leveranssäkerhet samt lönsamhet. Resultatet visade bland annat att användningen av grenar och toppar kan medföra klimatnytta. Vidare framkom att implementeringen av EU:s nya förnybartdirektiv inte kommer att ha storskalig påverkan på Stockholm Exergis framtida användning av dessa bränslen. Gällande leveranssäkerhet och lönsamhet påvisades exempelvis en större framtida efterfrågan på skogliga restprodukter från andra sektorer. Ändock kunde slutsatsen dras att skogliga biobräanslen, under vissa förutsäattningar, har en viktig roll i Stockholm Exergis framtida fjärrvärmeproduktion. / The study aimed to give a recommendation regarding how the district heating company Stockholm Exergi should design their future strategy concerning unprocessed solid woody biofuels. Through literature studies and interviews, the competitiveness of the fuels has been assessed based on climate neutrality, political directives and instruments, security of supply as well as profitability. Among other things, the results showed that the use of tree branches and tops can imply positive climate effects. Furthermore, the implementation of EU's new renewable energy directive will only have a marginal impact on Stockholm Exergi's future use of woody biofuels. Regarding the security of supply and profitability,an increased future demand of forest residues in other sectors have been identified. However, the study concludes that, under certain circumstances, woody biofuels have an important role in Stockholm Exergi's future district heating production.
