Abstract [en]

World is currently facing an energy crisis as well as a climate crisis. Among various strategies nurtured to triumph this global predicament adoption of clean sources for energy production lead in frontage. Baltic Biogas Bus is commendable endeavor initiated by the Storstockholms Lokaltrafik (SL) AB, Sweden and funded by the European Union under the Baltic Sea Region Program in order to face this reality via a pragmatic approach of transforming the entire public transportation system that run on conventional fuel in the Baltic Sea Region by introducing biomethane as an alternative. This thesis project has been thus conferred by SL AB and carried out in conjunction with the Baltic Biogas Bus project.

In this report a framework has been developed in a systems perspective to benchmark biomethane supply chains consisting of biogas upgrading, biomethane distribution and refilling with the focus of facilitating sustainability decision making in introducing biomethane as a public transportation fuel. Sustainability of a specific decision situation would therefore be signified by three performance indicators; climate impact, energy intensiveness and cost effectiveness at each phase of the supply chain. A ‘SWOT analysis’ and a ‘multi criteria analysis’ has been performed with the focus of facilitating the decision maker with a much holistic picture with regard to the three main pillars of sustainability; environmental, social and economic aspects.

Even though compressed biomethane systems have been widely adopted as a vehicle fuel so far promoting liquefied biomethane seems to be more viable in many aspects. However the latter is still in its infant stages and therefore the reliability of the accuracy of performance is still not proven solidly. In contrast venturing into the former system guarantees a more secured investment with proven accuracy of results and widespread availability of technological know-how. Distribution of compressed biomethane through gas grids seem to be a feasible option only in short distances and in very large scale whereas using composite swap bodies would be the most preferable alternative for biomethane distribution using on land transportation. Nevertheless distribution in liquefied form seems to be the most sustainable alternative among all forms of distribution irrespective of distance and quantity. Nurturing liquefied biomethane supply chains would manifest better performance in climate and cost perspectives while adopting compressed biomethane supply chains based on gas grids would lead to better energy intensiveness.
