Abstract [en]

Carbon capture and storage (CCS), including bioenergy with carbon capture and storage (BECCS), could contribute to climate change mitigation strategies. However, the 2020s is not the first time that CCS is high on the agenda. This study explores the differences between the past and current developments of CCS and discusses how incumbent actors' experiences can inform the understanding of potential future energy system transitions in Sweden. For this purpose, a multi-level perspective (MLP) analysis was conducted based on documents, interviews and focus groups with key actors. Since the 2000s, increased urgency of climate change has further pushed policy makers into action. In addition, there is a new framing of CCS that underscores the potential of BECCS to provide negative carbon dioxide (CO2) emissions, as well as prospects for offshore storage of CO2 in Norway and other territories. As such, this study shows that Sweden could be on a transformation pathway towards implementing CCS alongside other mitigation measures.

Abstract [en]

Bioenergy with carbon capture and storage (BECCS) is a chain of technologies to capture, transport and, store carbon dioxide of biogenic origin. There are countries and regions where BECCS could be a suitable part of the climate change mitigation toolbox.

With the aim of investigating the possible deployment of BECCS in Sweden, both qualitative and quantitative methods were used. Studies of the potential of BECCS often fail to account for the perspectives of the companies that are anticipated to do the implementation. This thesis takes its starting point in those perspectives. The thesis investigates critical factors for the deployment of BECCS and how these inform a possible transition pathway with BECCS. To improve the understanding of the context for the deployment of BECCS, the thesis also investigates alternative ways to capture carbon dioxide from the lime kilns in Kraft pulp mills and the potential to achieve negative emissions with wood-based panels.

The thesis finds that critical factors that can affect deployment include upcoming incentives and regulations, the availability of storage capacity, and the continued use of biomass. In the near to mid-term, any transition with BECCS will be reliant on incumbent actors and their reorientation. A key for BECCS is the framing around generating negative emissions, which is different from the framing of carbon capture and storage (CCS) from 20 years ago as an enabler of business as usual. Generating negative emissions is, however, a concept only possible through boundary selections and assumptions, and everyone using the same guiding principles lowers the risk of double counting and/or omission of emissions.

The thesis also finds that alternative technologies, i.e., oxyfuel combustion and electric arc plasma calcination, can capture carbon from lime kilns without using additional fuel and at the same time generate useful steam. Such alternatives can be important in a future with increased competition for biomass resources. It is also possible to achieve negative emissions with wood-based panels in Sweden. While this can provide an alternative with additional benefits, i.e., material for construction, this thesis finds that it is not possible to achieve negative emissions with wood-based panels on the same scale as the potential for negative emissions with BECCS.  

Abstract [sv]

Biogen koldioxidavskiljning (bio-CCS eller BECCS) är en kedja av tekniker för att avskilja, transportera och lagra koldioxid med biogent ursprung. Det finns länder och regioner där BECCS skulle kunna passa bra som en del av de samlade åtgärderna för att begränsa klimatförändringarna. 

Med syftet att undersöka den möjliga utbyggnaden av BECCS i Sverige har både kvalitativa och kvantitativa metoder använts. Studier av potentialen av BECCS misslyckas ofta med att redovisa perspektiven från de företag som väntas göra implementeringen. Den här avhandlingen har sin utgångspunkt i dessa perspektiv. Avhandlingen undersöker kritiska faktorer för utbyggnad av BECCS och hur dessa påverkar en möjlig omställning med BECCS. För att öka förståelsen kring kontexten för utbyggnad av BECCS undersöker avhandlingen även alternativa sätt att avskilja koldioxid från measugnar i sulfatmassabruk och potentialen att åstadkomma negativa utsläpp med träpaneler.  

Avhandlingen finner att kritiska faktorer som kan påverka utbyggnaden inkluderar kommande incitament och regelverk, tillgängligheten av lagringskapacitet, och den fortsatta användningen av biomassa. I närtid är alla omställningar med BECCS beroende av etablerade aktörer och deras omorientering. En nyckel för BECCS är inramningen runt att skapa negativa utsläpp. Denna inramning är annorlunda från inramningen av koldioxidavskiljning, transport och lagring (CCS) från 20 år sedan som en möjliggörare att fortsätta som vanligt. Att skapa negativa utsläpp är dock ett koncept som enbart är möjligt med hjälp av gränsdragningar och antaganden. Att alla följer samma guidande principer för dessa minskar risken för dubbelräkning och utelämnande av utsläpp. 

Avhandlingen finner också att alternativa tekniker, som syrgasförbränning och eldriven kalcinering med plasmateknik, kan avskilja koldioxid från mesaugnar utan att använda ytterligare bränsle och samtidigt generera användbar ånga. Sådana alternativ kan vara viktiga i en framtid med ökad konkurrens om biomassa. Det är också möjligt att åstadkomma negativa utsläpp med träpaneler i Sverige. Medan detta kan vara ett alternativ med flera fördelar, så som material för konstruktion, finner den här avhandlingen att det inte är möjligt att åstadkomma negativa utsläpp med träpaneler på samma skala som det är möjligt med BECCS.
