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. 收起
