Originating in the Silicon Valley, the term “Innovation Ecosystem is the evolving set of actors, activities, and artifacts, and the institutions and relations, including complementary and substitute relations, that are important for the innovative performance of an actor or a population of actors.” Creating energy sector innovation ecosystems has been challenging due to a multitude of participants, access to capital, role of governments, and challenges scaling promising technologies. With the need to develop and scale new technologies to achieve net zero by 2050, energy innovation will be the linchpin. What are critical factors for creating successful clean energy/tech innovation centers? Where are the most successful cleantech innovation ecosystems, and what makes them successful? Does the nature of the energy system make it less receptive to new ideas and innovations? How could governments incentivize these ecosystems? How could the pace of knowledge transfer be accelerated from innovation to deployment? With future growth in energy demand and investments centered in developing countries, how can new ecosystems be created in these countries?
