- In this article I summarize recent progress in the effective field theory approach to low energy nuclear systems, with a focus on the power counting issue. In the pionless sector, where the power counting is quite well understood at the nucleon-nucleon (NN) level, I discuss some recent developments toward few- and many-body calculations. In the pionful sector, I focus on the actively debated issue of power counting in the NN sector and some recent developments toward a model-independent NN interaction. Finally, the scenario that the power counting might depend on the number of particles is discussed.

- Bus fleet electrification achieves momentum and inspiration within public transport aiming at further improving the mobility sustainability. In many countries, such as Sweden, China, and the USA, there are several ongoing demonstration projects of electric buses and many research projects. The charging technology development and implication is key for the expansion of electric buses and to foster it. An investigation of characteristics and benefits of various existing and future charging technologies has been created in this paper. The main types of charging infrastructure are depot charging, station charging, and inductive charging. The choice of different types is highly related to infrastructure construction, investment, and daily operation. The detailed illustration and analysis of them can provide a solid foundation to the near-future large-scale electric buses’ operation.

CDM's influence on technology transfers : A study of the implemented clean development mechanism projects in China
- 2015

Tidskriftsartikel (refereegranskat)abstract
- Technology transfers through the Clean Development Mechanism (CDM) under the Kyoto Protocol is one of the most important catalysts in the cooperation between developed (Annex I) and developing (non-Annex I) countries for climate change mitigation. With the large-scale implementation of CDM projects in recent years, it is important to timely and comprehensively analyze the effectiveness of technology transfers in these implemented projects on the level of individual countries. In this context, China is of particular significance as it is the biggest host country of CDM projects in the world; 50% of total CDM projects implemented from 2007 to 2012 have issued Certified Emission Reductions (CERs) to 60% of all of the CDM projects. In this study, we evaluated the performance of technology transfers in an exclusive database of 754 CDM projects hosted by China between 2007 and 2012 with issued CERs since CERs were first issued in China. In addition, we developed a logistic regression approach using 11-variables that include a series of extended technology transfer-based indicators from the perspectives of project design, economic level, and technology capability that have not been studied in detail in the past. The results show that technology transfers are more likely to occur in large-sized projects with higher CER incomes, in projects with international participants, and in projects involving types such as HFC-23 reduction, fuel substitute, and N2O decomposition, in comparison to projects involving renewable energy. We observed that over 90% of the technology transfer projects only include importation of equipment or training to China. In our findings of the regression results, it shows that technology transfers occurred more often in regions with lower technology capabilities, less energy consumption, and a lower GDP growth rate. Supported by high local technology capability and the governmental strategy with independent innovation, the advantages of introducing technology from other countries are offset by local technology diffusion. In a market view, financial incentives hinder CDM host parties from introducing new equipment or trainings for the high marginal cost, unless the high marginal cost of technology transfer can be offset by a large CDM with a high CER income. Technology transfer is more income-driven than sustainability-driven at the present stage in China. In our analysis, the drive out effect between HFC-23 and renewable projects in CDM suggests China government to publish more effective incentives to attract more sustainable types of CDM projects with a higher level of technology innovation. The results are also discussed in the context of policy issues, which can be helpful for the decision makers when formulating future sustainable strategic plans and policy.

A Gap in the Grid : Attempts to introduce natural gas in Sweden 1967-1991
- 2013
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis follows the process of introducing natural gas in Sweden and the construction of a Northern European gas grid from 1967 to 1991. Natural gas is a relatively unnoticed fuel in Sweden today, but this relative anonymity stands in contrast to an extensive historical activity that has taken place behind the scenes of Swedish energy policy. The single pipeline constructed between Denmark and Sweden in the early 1980s was both preceded and followed by many other attempts to construct a larger natural gas pipeline in the region made in the last 50 years. Åberg traces these attempts while discussing the complex and messy process of constructing and managing a transnational energy infrastructure.Åberg follows actors in Sweden and other countries in their attempts to negotiate and construct a natural gas infrastructure, and puts this process into a national as well as transnational context. The perceived risks and opportunities surrounding natural gas are examined, together with factors that have influenced the development of natural gas in a broader sense. By seeing the changing and messy natural gas projects as arenas where different actors construct and negotiate risks and opportunities, as well as contexualize the projects, Åberg shows how the natural gas sector in Sweden has evolved and taken shape.The study shows that natural gas in Sweden has suffered from unstable actor coalitions on different levels, a difficult market situation, and a changeful political context, especially with regard to energy policy. The import status of the fuel and the consequential transnationality of the natural gas infrastructure have also made the process of constructing a pipeline more complex. However, natural gas was introduced in Sweden, showing that when a strong enough actor coalition agreed that there was enough reason to warrant a natural gas introduction and was ready to join this endeavor, a connection could be achieved. This puts into question to what degree general explanations in terms of finance and policy drive energy decisions, and makes a case for showing how these explanations are adapted into their social and historical contexts in sometimes surprising ways.

Capitalist eschatology: Immediacy, investment, ideology
- 2022
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper presents some preliminary ideas on how to study the place of eschatology in the contemporary economy, focusing specifically on space-colonizing ambitions of US entrepreneurs such as Elon Musk. Such a study may focus on three problematics, relating to immediacy, investment, and ideology. The study of what one may call “capitalist eschatology” involves interrogating the making of alternative futures, by situating imaginaries of humanity becoming a multiplanetary species in the present realities of political economy. The authors combine STS and ethnographic method with a history of technology perspective, in order to study both the present and the long roots of the sociotechnical and economic practices and imaginaries that make up such a “eschatology”.
