Cleaner heavy transports – Environmental and economic analysis of liquefied natural gas and biomethane

Marcus Gustafsson och Niclas Svensson

Abstract: Looking to reduce climate change impact and particle emissions, the heavy-duty transport sector is moving towards a growth within technology and infrastructure for use of liquefied natural gas (LNG). This opens an opportunity for the biogas market to grow as well, especially in the form of liquefied biomethane (LBM). However, there is a need to investigate the economic conditions and the possible environmental benefits of using LBM rather than LNG or diesel in heavy transports. This study presents a comparison of well-to-wheel scenarios for production, distribution and use of LBM, LNG and diesel, assessing both environmental and economic aspects in a life cycle perspective. The results show that while LNG can increase the climate change impact compared to diesel by up to 10%, LBM can greatly reduce the environmental impact compared to both LNG and diesel. With a German electricity mix, the climate change impact can be reduced by 45 – 70% compared to diesel with LBM from manure, and by 50 – 75% with LBM from food waste. If digestate is used to replace mineral fertilizer, the impact of LBM can even be less than 0. However, the results vary a lot depending on the type of feedstock, the electricity system and whether the calculations are done according to RED or ISO guidelines. Economically, it can be hard for LBM to compete with LNG, due to relatively high production costs, and some form of economic incentives are likely required.

Dimensions and characteristics of biogas policies – Modelling the European policy landscape

Marcus Gustafsson och Stefan Anderberg

Abstract: Biogas solutions typically span across several sectors, such as waste handling, energy and transport. While this can be an advantage in comparison to other alternatives, it also creates an intricate policy structure that is challenging to overview, making it difficult to evaluate consequences of different policy changes that might not be directly related to biogas. This article presents an attempt to describe the institutional conditions for biogas solutions in the EU by defining the dimensions and characteristics of policies and policy instruments influencing biogas. A five-dimensional model of biogas policies is proposed: type of policy; administrative area; administrative level; targeted part of the value chain; and continuity and change over time. This reflects the complexity of the conditions for biogas solutions and constitutes a platform for describing, discussing and developing biogas policies. From the proposed model, it becomes clear that biogas policy is a very dispersed and incoherent policy area. Thus, there is an apparent risk that the responsibility for biogas policy is diffuse and has no obvious owner among the involved actors, making the framework of biogas policies patchy and ineffective. This model can contribute to an improved overview of biogas policies, and can be used as a tool for comparing the policy landscapes in different countries.

Developing biogas systems in Norrköping, Sweden: An industrial symbiosis intervention

Axel Lindfors, Marcus Gustafsson, Stefan Anderberg, Mats Eklund, Murat Mirata

Abstract: Biogas systems are often multi-functional and involve several actors in different sectors, requiring these actors to collaborate closely in order to implement such systems. In this paper, a study is presented where the theory of institutional capacity building is used to guide interventions with public and private actors to facilitate the development of local biogas systems in Norrköping, Sweden. The interventions were performed in the form of a workshop series, where local actors with potential to influence biogas developments actively took part. The workshop series generated knowledge on Norrköping’s significant potential for both producing and using biogas, which was traced, in part, to its high concentration of bio-based industries and its good position as a hub for transports. The interventions also created a shared understanding that cooperation and coordination to distribute resources and knowledge about biogas, both geographically and across sectors, was critical for realizing this potential. The municipal organization was identified as an important actor for coordinating these efforts. Observations during the workshops and survey responses indicate that the interventions contributed to building institutional capacity and initiation of efforts to develop local biogas solutions. Ideas put forth in this study enable interventions to target the intangible internal capacities of emerging industrial symbiosis networks. In addition, institutional capacity building serves as a useful analytical framework capable of capturing progress within emerging networks in the short-term even when material, water or energy synergies are yet to be realized.
