• Utilizes 111 expert interviews and 50 site visits to examine UK industrial decarbonization. • Explores sociotechnical pathways, capabilities, and learning processes. • Harnesses a challenge-oriented regional innovation systems (CoRIS) framework. • Reflects on deeper issues of incumbency, innovation, and incremental vs. transformative change. Few sectors in the global economy need deep decarbonization as much as heavy industry, which is currently the largest and fastest growing source of global carbon emissions. Based on an original dataset of 111 expert interviews and 52 site visits, this paper asks: what sociotechnical pathways, capabilities, and regional innovation systems are emerging to support industrial decarbonization? It combines and applies insights from evolutionary economic geography and transitions studies, such as sociotechnical capabilities and learning, as well as spatial frameworks such as challenge-oriented regional innovation systems (CoRIS) and green industrial restructuring. It utilizes these collective concepts of pathways, capabilities and CoRIS to explore the organizational and technological, individual, and systems level dimensions of industrial decarbonization efforts ongoing across Great Britain. We find that within industrial net-zero clusters, spatial and technological proximities are being effectively leveraged, especially through new forms of networking, collaboration, and partnerships. CoRIS provides the basis for greater reflection on perennial transitions issues, both within and across clusters, related to incumbency and innovation, in addition to spotlighting emergent issues such as light versus deep green restructuring and incremental versus transformative change. In simpler terms, industrial decarbonization unfolds as a multi-scalar process. Industrial decarbonization exhibits both incremental and transformative patterns of change. Industrial decarbonization lastly involves dynamic processes that coevolve across a spectrum of sociotechnical attributes. [ABSTRACT FROM AUTHOR]

• Social innovations are essential for just sustainability transitions in energy. • Understanding potential of social innovation requires understanding its power dynamics. • Power dynamics in social innovation in energy include power to/over/with. • We require inter- and transdisciplinary power concepts to understand power in transitions. This paper explores how power relations are manifested, altered and/or reproduced in processes of social innovations in energy transitions (SIE). We explore this research question by developing an interdisciplinary and transdisciplinary power heuristic building on different dimensions of power: power to, power over and power with. This conceptual framework helps us analyse the power dynamics in multiple types of SIEs that aim to contribute to sustainable energy transitions across three different national contexts: Germany, Poland, and the United Kingdom (UK). Our findings show how social innovation involves different dimensions of power to/over/with, and how power relations are both altered and reproduced. The cases under study also lead us to argue that understanding how power dynamics develop requires the analysis of the interplay between different power dimensions across the multiplicity of actors within different SIE-fields and their initiatives.

• The article explores the development of local electricity exchange practices in three European countries: France, Switzerland, and great Britain; the comparative cases reveal the complexity and variation of the local electricity exchange phenomenon across our three national contexts. • Local electricity exchange has as much potential to cement conventional actors and power relations in the sector as it does to support new actors or transform power relations. • Local electricity exchange varies considerably across national contests and is strongly linked with institutional frameworks and policy regimes in place, including competing dynamics of centralization and shifting forms of ownership. • Considerable uncertainty exists concerning local electricity exchange markets of the future; their viability is to be proven and investments are needed for realization of the projects. Local electricity exchange is often praised for its ability to empower consumers and benefit communities. In this paper, we investigate and compare the development of local electricity exchange practices in three European countries: France, Switzerland, and Great Britain. We ask: how do local electricity exchange practices and markets vary across national contexts? What are their dynamics of ownership and consolidation, if any? What areas of contestation or disagreement emerge? To answer these questions, we first briefly define and conceptualize local electricity exchange and its categories before explicating our mixed methods research design consisting of document analysis, 40 original expert interviews across the three countries, and observational data derived from seven meetings and events. These comparative cases reveal the complexity and variation of the local electricity exchange phenomenon across our three national contexts, how such acts of decentralization in turn (and perhaps unpredictably) consolidate power among incumbent actors, and how local electricity exchanges are prone to significant contestation and disagreement. Moreover, they reveal competing dynamics of centralization and shifting forms of ownership. We conclude by noting that (i) local electricity exchange has as much potential to cement conventional actors and power relations in the sector as it does to support new actors or transform power relations; (ii) approaches to local electricity exchange vary considerably across national contexts and are strongly linked with institutional frameworks and policy regimes; and (iii) the future merits of local electricity exchange are prone to great uncertainty and contestation.
