Constructing a typology of H2 in cities and regions -: An international review

This paper primarily develops a seven-fold conceptual typology of place-based hydrogen initiatives. Through an international review of place-based hydrogen initiatives we reveal a plethora of projects, demonstrations, test-beds, ambitions and expectations at a wide range of spatial scales. We ask whether there is anything distinctive about how these different spatial scales attempt to develop the hydrogen economy. In particular, we seek to identify whether patterns emerge around the social interests involved at different scales of activity and the degree to which hydrogen links to different place-based agendas-political and resource autonomy, economy and employment. The paper addresses these questions and draws out a series of three key conclusions. First, there is wide ranging and significant diversity in the motivations for cities and regions to become involved in hydrogen economy developments-wider than conventional energy policy objectives. Second, there are still significant overlaps between different scales of action. Third, there is a tension between the more bounded concepts of using hydrogen to build self-reliance at a particular scale and those initiatives oriented around developing a more systemic technological system which is rolled out elsewhere. Finally, we argue that a key issue for further research is in understanding the social interests and institutions that attempt to both learn from across these activities at different scales and provide some sense of coordinated action between them. In our review the role of corporates-rather than national government-seems to be critical to such attempt to provide coordination across places and needs to be the focus of further research.
