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.

Abstract [en]

Many bio-based technologies are emerging technologies, with the characteristics of being radical and fast growing. The 2018 Nobel prize in chemistry is based on enzymatic bio-based conversion as a green alterative for several conventional technologies. Overall, the transition to a bio-based economy is seen as a mean to reach sustainability, energy independence and economic growth. Bioeconomy strategies have however also been criticized for focusing too much on economic growth and too little on sustainability. Assessing potential life cycle sustainability risks and benefits early in the development of technologies – when still at lab or pilot scale – provides valuable insights about how to prioritize research activities and to potentially avert unintended consequences. The lack of knowledge and high uncertainty in early development however also makes such assessments challenging. On the social sustainability side, bio-based technologies create new jobs, while the social acceptance can hinder the market growth even in an innovation country like Sweden. Emerging technologies like for example artificial intelligence might reduce jobs and gene therapy in medicine might bear risk for coming future generation. The questions and risks are manifold. Therefore, it is essential to have a roadmap for guidance that takes a holistic approach to sustainability with a life cycle perspective. To add to the complexity, the possibilities for assessment approaches are extensive. Different perspectives can be assessed in numerous ways and with many different methods. The goal of this study is to contribute to a sustainable transition to the bioeconomy, by serving as a roadmap for research and innovation (R&I) on emerging bio-based technologies.

To suggest a general roadmap for holistic and interdisciplinary assessments, this study identifies, and describes the use of multiple perspective assessments in selected R&I projects on emerging bio-based technologies. The projects include virgin and waste raw materials, biotechnology conversion processes and products such as bio-based chemicals, building materials, soil amendment, and pellets for heat. The findings are, in combination with existing frameworks on biomass- and bio-product prospect models, used to suggest an assessment roadmap for identifying sustainability prospects of emerging bio-based technologies.

The result consists of an “assessment roadmap” including the perspectives resource-, economic-, environmental-, social- and market potential. Each perspective is accompanied by questions targeted to identify benefits and risks, such as “What valorization routes currently exists, and are under research, for the feedstock?”; “Is the feedstock available, also in the future?”; “Is the production technology socially accepted?”. The roadmap for bio -based emerging technologies also provides advice on the procedure for sustainability assessments, such as organizing an initial workshop with expert knowledge and highlight the importance of scanning before allocating resources for in depth analyses.

Abstract [en]

Waste, also food waste, abound. From an environmental point of view food waste should first and foremost be avoided. However, the waste that inevitably is produced along the food production chain should be utilized to the best of our ability. One option is to produce biobased chemicals and materials from the waste through biological processes. This study looks into what food waste resources are available for such production, industrial fermentation, in Sweden, from waste emanating in primary production all the way through to final consumption. In addition, drivers for waste generation, influencing institution and waste market characteristics are assessed.

Abstract [en]

Forest-derived biofuels have been on the agenda for several decades. Despite extensive research and development efforts, forest biofuel concepts have nevertheless not yet been realized on any significant scale. The discrepancy between the expectations from the research community and the lack of momentum regarding biofuel production raises the question of if and how research results can be used to achieve such goals. Here, we report results from an interview study with the aim of evaluating how energy system models can be used to illustrate barriers and drivers for forest biofuels, with focus on Swedish conditions, using the BeWhere model as case. The study is framed as an example of expertise, and problematizes how energy system models are interpreted among expected users. While the interviews revealed some general scepticism regarding models, and what kinds of questions they can answer, the belief was also expressed that increased complexity might be an advantage in terms of being able to accommodate more barriers against forest biofuels. The study illustrates the complexity of this policy area, where an energy system model can answer some, but never all, 'what if.?' questions. The results reveal a need for reformation in energy system modelling in order to more explicitly make society the subject of the work, and also illustrate that the belief in expertise as a tool for consensus-building in decision-making should be questioned.

Abstract [en]

Sugarcane ethanol systems can deliver large greenhouse gas emissions savings if emissions associated with land-use change are kept low. This qualitative study documents and analyzes actions and opinions among Brazilian farmers who shift to sugarcane production. Semi-structured interviews were held with 28 actors associated with sugarcane production in three different regions: one traditional sugarcane region and two regions where sugarcane is currently expanding. Most farmers considered sugarcane a land diversification option with relatively low economic risk, although higher risk than their previous land use. Beef production was considered a low-risk option, but less profitable than sugarcane. In conjunction with converting part of their land to sugarcane, most farmers maintained and further intensified their previous agricultural activity, often beef production. Several farmers invested in expanded production in other regions with relatively low land prices. Very few farmers in the expansion regions shifted all their land from the former, less profitable, use to sugarcane. Very few farmers in this study had deforested any land in connection with changes made when shifting to sugarcane. The respondents understand "environmental friendliness" as compliance with the relevant legislation, especially the Brazilian Forest Act, which is also a requirement for delivering sugarcane to the mills. Indirect land-use change is not a concern for the interviewed farmers, and conversion of forests and other native vegetation into sugarcane plantations is uncontroversial if legal. We derive hypotheses regarding farmers' actions and opinions from our results. These hypotheses aim to contribute to better understanding of what takes place in conjunction with expansion of sugarcane and can, when tested further, be of use in developing, e.g., policies for iLUC-free biofuel production.
