  • Bioenergy futures in Sweden - system effects of CO2 reduction and fossil fuel phase-out policies
  • 2015
  • Ingår i: GCB Bioenergy. - : Wiley. - 1757-1707 .- 1757-1693. ; 7:5, s. 1118-1135

    • Bioenergy could contribute both to the reduction of greenhouse gases and to increased energy security, but the extent of this contribution strongly depends on the cost and potential of biomass resources. For Sweden, this study investigates how the implementation of policies for CO2 reduction and for phase out of fossil fuels in road transport affect the future utilization of biomass, in the stationary energy system and in the transport sector, and its price. The analysis is based on the bottom-up, optimization MARKAL_Sweden model, which includes a comprehensive representation of the national energy system. For the analysis, the biomass supply representation of MARKAL_Sweden is updated and improved by the use of, e.g., forestry forecasting modeling and through construction of detailed biomass supply curves. A time horizon up to 2050 is applied. The results indicate a potential for significantly higher use of bioenergy. In the main analysis scenario, in which CO2 reduction of 80% by 2050 is imposed on the Swedish energy system, the total bioenergy utilization increases by 63% by 2050 compared to 2010. The largest increase occurs in the transport sector, which by 2050 accounts for 43% of the total primary bioenergy use. The high demand and strong competition significantly increase biomass prices and lead to the utilization of higher cost biomass sources such as stumps and cultivated energy forest, as well as use of pulpwood resources for energy purposes.

  • Integration of next-generation biofuel production in the Swedish forest industry – A geographically explicit approach
  • 2015
  • Ingår i: Applied Energy. - : Elsevier BV. - 0306-2619 .- 1872-9118. ; 154, s. 317-332

    • The geographic locations of biofuel production facilities should be strategically chosen in order to minimise the total cost of using biofuels. Proximity to biomass resources, possibilities for integration, and distance to biofuel users are aspects that need to be considered. In this paper, the geographically explicit optimisation model BeWhere Sweden was used to investigate the future production of next-generation biofuels from forest biomass in Sweden. A focus was placed on the integration of biofuel production with the existing forest industry, as well as on how different parameters affect biofuel production costs, the choice of technologies and biofuels, and the localisation of new biofuel plants. Six examples of different biofuel routes were considered. A methodology was developed considering detailed, site-specific conditions for potential host industries. The results show that the cost of biomass and the biofuel plant capital cost generally dominate the biofuel cost, but the cost for biomass transportation and biofuel distribution can also have a significant impact. DME produced via black liquor gasification (naturally integrated with chemical pulp mills) and SNG produced via solid biomass gasification (mainly integrated with sawmills), dominate the solutions. The distribution of these technology cases varies depending on a number of parameters, including criteria for sizing biofuel plants, the electricity price, the biofuel distribution cost and the cost of biomass, and is sensitive to changes in these parameters. Generally, plants with low specific investment costs (i.e., high biofuel production) and/or plants with low specific biomass transportation costs occur most frequently in the solutions. Because these properties often vary significantly among biofuel production facilities at different host industry sites of the same type, the results show the advantage of including site-specific data in this type of model.

  • Supply assessment of forest biomass : A bottom-up approach for Sweden
  • 2015
  • Ingår i: Biomass and Bioenergy. - : Elsevier BV. - 0961-9534 .- 1873-2909. ; 75, s. 213-226
  • Tidskriftsartikel (refereegranskat)abstract
    • As there is increasing interest in the use of biomass for energy in Sweden, the potential availability and harvesting costs of forest roundwood, harvesting residues and stumps were estimated up to the year 2069 in 10-year intervals, using a high spatial resolution GIS. In each individual forest area, an average harvesting cost per forest assortment was estimated, based on the geographic and other properties of the area. Using cost structure and resource availability, marginal cost curves were constructed to allow analyses of the effects of changing market conditions and different policy frameworks. Based on geographically explicit data, the results indicated that the average harvesting costs would be 21–24 € m−3 for roundwood, depending on the type of harvesting and extraction operation. The corresponding cost estimate for harvesting residues was 23–25 € m−3 and 35 € m−3 for stumps. The harvesting cost estimates lie on the steeper part of the marginal cost curve, suggesting that increases in the supply of woody biomass can only occur at significantly higher harvesting costs. From a policy perspective, this suggests that subsidies aimed at reducing the harvesting costs will only have limited success in increasing the harvested volumes, given current technology. Therefore, for future development in the supply of forest assortments for energy generation, it is important to consider not only the supply potential, but also the integration of improvements in harvesting and transportation systems.

  • The Role of Public Policies for Energy Technology Development : Their Innovation Effects and Interaction
  • 2015
  • Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • The overall purpose of this thesis is to analyze the role of public policies for technological development (i.e., innovation) in the renewable energy sector. The thesis consists of an introductory part and three self-contained papers.Paper I investigates the innovation effects of renewable energy support policies and their interaction in the empirical context of solar photovoltaic (PV) technology. This is achieved by using data on solar PV patent counts and policies targeting solar PV development across 13 countries over the time period 1978-2008. These policies include public R&D support to solar PV as well as two different types of production support schemes: feed-in tariffs (FIT) and renewable energy certificates (REC). The data are applied to a negative binomial model and the results indicate that: (a) both FIT and REC schemes stimulate solar PV patenting activity although the impact of the former is of a larger magnitude; (b) public R&D has been more influential than the production support schemes in inducing solar PV innovation; and (c) policy interaction exists in that the innovation effect of public R&D support is greater at the margin if it is accompanied by the use of FIT schemes for solar PV.Paper II analyzes the role of pilot and demonstration plants (PDPs) in technological development. As surprisingly little explicit attention has been devoted to this issue in prior research, the existing literature is synthesized and categorized, and an agenda is proposed for future work. Scholarly work on PDPs can be found across several research fields and the discussion in the paper is organized around three research streams: engineering and natural science research, technology and innovation management, and innovation systems. Based on searches in key bibliographic databases more than 200 publications were identified and reviewed. According to the literature synthesis, the plants bridge basic knowledge generation and technological breakthroughs on the one hand (promoted by public R&D support), and exploitation of new technology for commercial use on the other (promoted by production support schemes). Still, more research on the subject is needed. For instance, the role of PDPs for inducing innovation needs to be assessed in a rigorous empirical setting as this issue has only been researched in conceptual studies or retrospective case studies based entirely on qualitative or descriptive approaches. Paper III provides an econometric analysis of the innovation impacts of publicly funded PDP activities in the case of advanced biofuel technology. This is achieved by using data on biofuel patent counts and PDPs across eight European countries over the time period 1980-2011. It is acknowledged that PDPs have two main objectives: testing and optimization of technology (experimental PDPs), and diffusion and commercialization of technology (exemplary PDPs). The data are applied to a negative binomial model and indicate that: (a) PDP activities are overall positively correlated with biofuel patents; (b) experimental PDPs are more innovation-promoting than exemplary PDPs; and (c) experimental PDP activities encourage innovation also indirectly through knowledge spillovers.The overall conclusion is that environmental policy encourages renewable energy innovation. Public R&D support as well as production support schemes are important for inducing innovation, and there are interactions between these policy types which must be acknowledged when designing public support. As public R&D support is more innovation-promoting when accompanied by the use of certain production support schemes, these policies should be employed simultaneously. Moreover, publicly funded PDP activities foster innovation and thus, their role must also be acknowledged when designing public policy.

  • Meeting Challenges in Forestry : Improving Performance and Competitiveness
  • 2021
  • Ingår i: Forests. - : MDPI. - 1999-4907 .- 1999-4907. ; 12:2
  • Tidskriftsartikel (refereegranskat)abstract
    • Improving the efficiency of the forestry sector will have an important impact on our possibility to attain long-term sustainability and mitigate climate change. In this study, attainable, and sustainable, efficiency improvements in the harvesting of forest products are analyzed using Data Envelopment Analysis (DEA). The price impacts of the efficient harvesting volumes are evaluated in a second step using a spatial forest sector model. The results indicate that the harvested volumes of forest products, both for the industry and energy sectors, can be significantly increased if a more efficient forest management is adopted. This supply-side effect will also result in general price decreases for sawlogs, pulpwood, fuelwood and harvesting residues. However, in certain counties, and for specific forest products, the estimated decreasing price effect from a more efficient forest management cannot fully offset the increasing price effect of the energy sector expanding its use of forest products. More forest biomass enters the market, which is needed in the transition towards a bioeconomy, and the increased availability of forest biomass will restrict the price effect making investments in the bioeconomy more likely to be profitable.

  • Cost-Benefit Analysis of climate policy and long term public investments
  • 2016
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • This compilation dissertation consists of four essays with the common theme of welfare analysis of long-term public investments. The first two essays focus on analysis of climate change mitigation, i.e., the social cost of carbon dioxide. The third essay focuses on cost-benefit analysis (CBA) of transport investment projects, while the last essay takes a broader perspective on welfare analysis.Essay 1: The Temporal Aspects of the Social Cost of Greenhouse Gases. The purpose of Essay 1 is to investigate the temporal aspects of the social cost of greenhouse gases. I find that the calculation period should ultimately be modeled to be consistent with the discount rate and that the “global-warming potential” concept is unsuitable for calculation of the social cost of GHGs other than carbon dioxide.Essay 2: Avoiding path dependence of distributional weights: Lessons from climate change economic assessments. In Essay 2, I explore shortcomings in income weighting in evaluation of climate change policy. In short, in previous versions of two of the most important existing models, regional economic growth is double counted. The proposed alternative approaches yield about 20–40% higher values of SCCO2 than the old approach.Essay 3: Does uncertainty make cost-benefit analyses pointless? In Essay 3, the aim is to investigate to what extent CBA improves the selection decision of projects when uncertainties are taken into account, using a simulation-based approach on real data of infrastructure investments. The results indicate that, in line with previous literature, CBA is a rather robust tool and considerably increases the quality of decision making compared with a random selection mechanism, even when high levels of uncertainty are considered.Essay 4: Household Production and the Elasticity of Marginal Utility of Consumption. In Essay 4, I develop a new model to show that omission of household production in a previous model leads to bias when the elasticity of marginal utility of consumption, EMUC, is estimated. I further offer new, unbiased estimates based on current evidence of the included parameters, suggesting a lower bound of EMUC at about 0.9.

  • Evaluating fuel switching options in the Swedish iron and steel industry under increased competition for forest biomass
  • 2022
  • Ingår i: Applied Energy. - : Elsevier. - 0306-2619 .- 1872-9118. ; 324
  • Tidskriftsartikel (refereegranskat)abstract
    • Significant use of forest biomass in the iron and steel industry (ISI) to mitigate fossil CO2 emissions will affect the biomass availability for other users of the same resource. This paper explores the market effects of increased forest biomass competition when promoting the use of forest-based bio-products in the ISI, as well as the interactions between the ISI and the forest industries. We employ a soft-linking approach that combines a geographically explicit techno-economic energy system model and an economic partial equilibrium model of the forest industries and forestry sectors. This allows for iterative endogenous modelling of new equilibrium price developments for different biomass assortments, determining locational choice of bio-products and assessing optimal bio-products technology choices. The results indicate an upward pressure on biomass prices when bio-products are introduced in the ISI (up to 62%), which affects both forest industries and the ISI itself. Prudence is thus warranted not to render bio-production investments uneconomical ex-post by neglecting to include potential price effects in investment decisions. The estimated price effects can be mitigated by increased domestic biomass supply, adjustments of international trade or by revising relevant policies. Even though the results suggest that the price effects will affect the geographical preferences for individual bio-production plants, proximity to the ISI production facility and integration benefits are more important than the proximity to cheaper biomass feedstocks. Product gas production integrated at ISI sites emerges as particularly attractive, while charcoal production exhibits sensitivity to fluctuating markets, both regarding resulting cost for the ISI, and preferred production locations.
