The transportation sector is undergoing a significant shift towards electrification, driven by sustainability challenges and battery electric vehicle (BEV) technology advancements. This transition also leads to a convergence of transport and energy industries, introducing new dynamics and creating new business opportunities in these sectors. Such changes have extensive implications not only for single firms but for entire ecosystems as these adapt to new technologies, activities, and business models. This study introduces the concept of Industry-Converging Ecosystems, where traditional industrial boundaries become less distinct, requiring collaboration among unfamiliar participants across various industries. This paper investigates the tensions between value creation and value capture and control in such ecosystems through a case study of an innovative electric charging system for buses in V & auml;ster & aring;s, Sweden. The findings advance ecosystem research by (1) introducing the industry-converging ecosystem concept, (2) revealing two sources for business model tensions stemming from monetisation uncertainties and resource competition, and (3) demonstrating the lack of clarity in ecosystem control caused by limited influence over business models and diminished legitimacy due to their newness.
