Advanced materials hold significant potential to create better products and production processes. Yet realising their promise remains challenging: historically it has taken 15 to 20 years from discovery to deployment of new materials in products. Consequently, governments have been creating shared digital and physical infrastructures – “collaborative platforms” – to pool and manage global data, drive the development of nascent industries, and create hubs of interdisciplinary research, development and training. Based on evidence from 12 case studies, this report characterises governance mechanisms of collaborative platforms for advanced materials such as terms of funding, access, and IP policy and explores how they can create different kinds of value. Technology convergence, the engagement of society and digitalisation are identified as key trends. The study describes conditions under which collaborative platforms can align and power value chains, foster standards, catalyse innovation ecosystems and build education, skills and social capital.
