The energy transition is one of the most significant challenges of our time. By 2050, more than 13 trillion of dollars of investments are expected in the electricity sector, with 77 percent from renewable sources. In this context, the open innovation paradigm should play a key role in reducing the costs of current technologies, creating new markets and reshaping the existing ones through the interaction of the five main stakeholders in this process: universities, corporations, governments, entrepreneurs and venture capitalists. In the first article, we show the importance of the interaction of the first three actors around mission-oriented public policies. We build a framework that can address the best practices of this type of policy when applied to the energy transition context. In the second, we seek to identify the patterns that have led energy startups to success or failure over the past 20 years. We find that business models, invested values, and investor profiles play a key role in these trajectories. Finally, considering the relevance of the relationship between startups and corporations during the energy transition, we analyzed in the third article the role of corporate venture capital (CVC) over the last 25 years and we recognize the fifth wave of CVC, which has many particularities and drives the CVC units to the innovation s strategic center of modern corporations. Overall, we conclude that all these main five stakeholders have a distinct but fundamental role in the energy transition.
