Biogas offers a sustainable alternative to fossil fuels, promoting circularity and local economic growth. It is, therefore, increasingly prioritised by decision-makers within Sweden and the EU. Despite its advantages, the Swedish market is perceived as underachieving in terms of scale and penetration. Biogas, a socio-technical system, has necessitated state and regional support for its establishment and expansion, given its competition with entrenched fossil fuels and its inherent material limitations. This thesis primarily seeks to explore how the interplay of political, societal, and market perspectives has influenced the biogas market. The research zeroes in on the Swedish biogas market, with a special focus on the impact of geographical regions on market shaping.To Janet, Terri, Vanessa, and Vic for knowing and loving me for the vast majority of my life. To my Mom and Dad for our daily video calls and all the love and support. Also to my dad, thank you especially for my stubbornness! I came about that honestly as we say, and it has been this one trait that made this happen. To my sister, who I can always count on to keep me company during lunch and distract me from all the day-to-day worries. RIP to little flora, the best four-legged study partner ever and who kept me company while studying for many years.Lastly, a big shout-out to all public libraries and their wonderful librarians. I can honestly say that without those wonderful small libraries in small towns, providing a sanctuary and inspiration to all who seek, I would never have made it this far. viii
