    The critical role of informed political direction for advancing technology: The case of Swedish marine energy2017In: Energy Policy, ISSN 0301-4215, E-ISSN 1873-6777, Vol. 101, p. 52-64Article in journal (Refereed)
    Abstract [en]

    Marine energy technologies can contribute to meeting sustainability challenges, but they are still immature and dependent on public support. This paper employs the Technological Innovation Systems (TIS) framework to analyze the development and diffusion of Swedish marine energy up until 2014. While there were promising device developers, relevant industrial capabilities, and world-class research, the system suffered from weaknesses in several important innovation processes. Finally, the analysis identifies the lack of informed political direction as a critical blocking factor and highlights its connection to domestic market potential.

    District heating as a flexibility service: Challenges in sector coupling for increased solar and wind power production in Sweden2023In: Energy Policy, ISSN 0301-4215, E-ISSN 1873-6777, Vol. 172, article id 113332Article in journal (Refereed)
    Abstract [en]

    With expanding solar and wind power production, the topic of flexibility services attracts increased attention in the Swedish energy system. In this context, the potentials in using thermal storage capacities in district heating (DH) systems have been brought forward, primarily by academic scholars. Using a ‘grounded’ approach, this study investigates if professionals assigned to Swedish DH companies and electricity distribution system operators utilise, or plan to utilise, DH systems as flexibility services for the electricity grid. Original data was collected through semi-structured interviews, held with fourteen individuals affiliated to different actors in the Swedish energy system. These individuals were identified as being experts, or practically engaged, in using DH utilities as flexibility services for the electricity grid. The findings show that although technologies for coupling between DH systems and the electricity grid are already in place, initiatives for using DH systems as flexibility services for the electricity system are rare in Sweden. Coupling challenges stem from ownership and operation legislation frameworks, marginal incentives and a widespread focus on firm benefits rather than energy systems benefits. Identified initiatives for using DH systems for flexibility services are primarily run on a local scale, designed and propelled by small groups of engaged individuals.

    Vertical integration of local fuel producers into rural DH systems: Climate impact and production costs2015In: Energy Policy, ISSN 0301-4215, E-ISSN 1873-6777, Vol. 78, p. 51-61Article in journal (Refereed)
    Abstract [en]

    Farmers can use their own agricultural biomass residues for heat production in small-scale systems, enabling synergies between the district heating (DH) sector and agriculture. The barriers to entry into the Swedish heat market were extremely high as long as heat distribution were considered natural monopoly, but were recently lowered due to the introduction of a regulated third party access (TPA) system in the DH sector. This study assesses the potential impact on greenhouse gas emissions and cost-based heat price in the DH sector when farmers vertically integrate into the heat supply chain and introduce more local and agricultural crops and residues into the fuel mix. Four scenarios with various degree of farmer integration, were assessed using life cycle assessment (LCA) methodology, and by analysis of the heat production costs. The results show that full integration of local farm and forest owners in the value chain can reduce greenhouse gas emissions and lower production costs/heat price, if there is an incentive to utilise local and agricultural fuels. The results imply that farmer participation in the DH sector should be encouraged by e.g. EU rural development programmes.

    The impact of blending mandates on biofuel consumption, production, emission reductions and fuel prices2023In: Energy Policy, ISSN 0301-4215, E-ISSN 1873-6777, Vol. 183, article id 113835Article in journal (Refereed)
    Abstract [en]

    The transport sector accounts for about 20% of EU’s GHG-emissions. Progress in emission reductions has been slow and primarily driven by biofuels promoted through national blending mandates. The mandates differ in whether they are measured in volume, energy, or emission reduction and in how gasoline and diesel are targeted. Due to this, national mandates and their effects have not previously been quantitatively compared on an EU level. In this article we convert the mandates for all EU member states between 2009 and 2020 to a common unit and study their impact on biofuel consumption, production, emission reductions and fuel prices. We find that mandates are driving biofuel consumption in the EU and correlates with emission reductions. Increased mandates have however often been fulfilled by blending biofuels eligible for double counting. We also find that reduction mandates have been effective in encouraging high-performance biofuels. For historical fuel prices, we do not see a clear correlation between countries’ shares of biofuel and consumer fuel prices while the global oil price has a considerable impact. For biofuel production, increased demand drive investments in the EU, but when it comes to localisation of new plants factors such as local infrastructure are more important than national mandates.

    Pathways for the development of future intelligent distribution grids2022In: Energy Policy, ISSN 0301-4215, E-ISSN 1873-6777, Vol. 169, article id 113140Article in journal (Refereed)
    Abstract [en]

    The next decade will bring several technical and organisational challenges to the electrical distribution grids, which are becoming an important pillar of the energy transition. Distribution system operators will play a crucial role and thus need to find innovative solutions that will prepare them for these changes. Acknowledging large differences between European distribution grids, this paper presents pathways for distribution system operators developed within the scope of the UNITED-GRID project, in close cooperation with distribution grids in the Netherlands, France and Sweden. Investment decision tools based on future scenarios and future-readiness assessment form the first step to steer the distribution system operators towards the necessary technical and digital innovations that increase the observability and controllability of the grid. Secondly, new types of business models are introduced that can be integrated into the operators’ portfolios. Thirdly, a workshop methodology is proposed to define the new internal requirements that make distribution system operators more agile to face the fast impacts of the energy transition. Case studies from the demonstration sites in the three countries are used as examples in the paper. © 2022 The Authors

    Don't extinguish my fire – Understanding public resistance to a Swedish policy aimed at reducing particle emissions by phasing out old wood stoves2022In: Energy Policy, ISSN 0301-4215, E-ISSN 1873-6777, Vol. 167, article id 113017Article in journal (Refereed)
    Abstract [en]

    Wood stoves emit particulate matter when used for domestic heating. Consequently, the National Board of Housing, Building and Planning in Sweden enforced a prohibition of new installations of old wood stoves in 2017 to protect the public health. The prohibition caused a public backlash that organized itself as a “wood stove rising”, eventually leading to a cancellation of the new legislation in 2019. We performed comprehensive interviews with 11 signatories of the original appeal to analyze the underlying motives for combating the implementation of this pro-environmental energy policy. We find that domestic heating through fire-making is an age-old human behavior that is deeply connected to several social and emotional human needs, but also to survival in remote areas with cold climate. The likelihood of policy observance and acceptance is higher if the policy is not perceived as being in direct conflict with these needs: basic emotion regulation, sensations of tradition and connection to other people, and means of crisis management for the individual. We also find that the protesters acted out of a sustainability perspective, albeit one where the continued use of functional devices was valued more than the perceived wear-and-tear of replacing outdated technology. © 2022 The Authors
