Negotiating contested visions and place-specific expectations of the hydrogen economy

This paper explores the role of the `hydrogen economy' as a guiding vision encompassing multiple contested technological futures, value judgements and problem framings. Hydrogen visions draw upon six overarching and competing narrative themes: power and independence; community empowerment and democratisation; ecotopia; hydrogen as technical fix; inevitability and technical progress; and `staying in the race'. In other words the hydrogen economy possesses great interpretive flexibility. This, it is argued, is the key to hydrogen's rhetorical power, allowing it to become a space in which divergent interests and agendas are promoted. Turning to issues of scale and place, the case of London is used to document the dynamics of expectations: how the open flexible guiding vision of a hydrogen economy must inevitably be re-invented and grounded in local agendas and contexts if its promise is to become realised
