While nexus research in sustainability science has investigated the consequences of connected systems, it has paid less attention to the processes of building nexuses which is becoming increasingly important in low-carbon transitions because these often require the creation of new connections between multiple consumption-production systems. Building on multi-system research in the sustainability transitions literature, this paper introduces a conceptual system interface perspective on nexus-building which considers four dimensions (technology, actors, institutions, and resources) that are useful for analyzing nexus-building dynamics. We apply our framework to the case of electrification of ferries in Norway which requires the building of a new interface between the electricity system and the maritime transport system. The case study shows that the system interface was initially characterized by conflicts and tensions in all dimensions, which actors then attempted to resolve through cross-system intermediation and adjustment activities. These activities were asymmetrical because of differences in external pressures, urgency, unequal power relationships, and different degrees of interest in cross-system nexus building. Because important tensions remained unresolved, ferry actors started implementing sub-optimal workaround solutions in the diffusion phase. [ABSTRACT FROM AUTHOR]

The innovation literature increasingly addresses grand challenges and transformative change. However, the issue of to what extent transformative change can build upon the resources, actors and institutions of existing innovation systems has not received sufficient attention. Against this background this paper aims to advance our understanding of the geographies and continuities of transformative change, by exploring the role of regional innovation systems in mission-oriented innovation. Based on an in-depth case study of electrification of ferries in Western Norway, the paper finds that the accomplishment of the mission was in large part due to the fact that it created new regional economic opportunities and built upon and mobilized existing regional resources, actors and structures. This mission re-orientation of an existing regional innovation system was characterized by (a) limited contestation, low complexity and low uncertainty about the technological battery-driven solutions pointed at, (b) multi-actor and multi-scalar agency and finally (c) asset modification of strong and pre-existing RIS structures, institutions and regulatory context.
