Addressing climate change requires a transition to sustainable energy and mobility solutions. However, these transformations present challenges: the growth in renewable energy is placing an increasing strain on grids, and achieving widespread acceptance of battery electric vehicles remains difficult. Bidirectional charging can address both problems. Battery electric vehicles serve as energy storage devices to stabilize the grid, thereby generating revenue. Of particular note is the application in an industrial context given the fleets of company and employee vehicles; consequently, this application is the focus of this dissertation. Despite the great potential, establishment and scaling remain challenging. There is a lack of research on acceptance of bidirectional charging among employees as users, firm adoption for introducing the technology into fleets, and the business model for the orchestrator as an intermediary in the cross-industry ecosystem between the mobility and energy industries. To address these challenges, three studies were conducted as the core of the dissertation. The first study uses a choice-based conjoint analysis involving 772 employees from German companies to capture users’ needs and preferences for bidirectional charging at the workplace. In the second study, a Technology-Organization-Environment framework is applied to examine drivers and barriers to the firm adoption of bidirectional charging through 36 interviews with fleet and energy managers. Both studies provide important input for the orchestrator’s business model within a cross-industry ecosystem, which is comprehensively analyzed in the third study based on 37 expert interviews and a stakeholder workshop with 38 experts. The results show that employees have significant concerns about battery degradation and mandatory plug-in times in making their vehicles available for bidirectional charging, while financial compensation and minimum range are less relevant in the workplace context. Companies are driven by economic considerations and only introduce bidirectional charging if reliability and profitability are assured. The complexity of implementing and operating is a major concern for companies, especially since many are still undergoing the transition to electric mobility. The orchestrator in the cross-industry ecosystem must take these preferences into account and deliver a value proposition to both end customers and ecosystem partners. This creates customer value by offering a full-service solution comprising complementary components, as well as orchestration value by connecting all partners from both industries on an interoperable platform. Consequently, this enables the orchestrator to capture double value, with interoperability serving as the foundation for further scaling. Overall, through a comprehensive analysis of employee acceptance, firm adoption, and business models within a cross-industry ecosystem, this dissertation lays the foundation for bridging mobility and energy industries using bidirectional charging in industrial applications.
