Many analyses examining the transition to a low-carbon energy system in the United States identify carbon capture, utilization, and sequestration (CCUS) technologies as critical in order to make progress toward deep decarbonization. These technologies have proven difficult to develop and scale, however, and much uncertainty remains about the durability and longevity of policies and incentive structures designed to demonstrate their feasibility. Funds from this grant support work by David Victor and his team at the University of California, San Diego to examine the economic, political, institutional, and technological barriers that are impeding the development of CCUS technologies. First, the team will survey the literature and develop a typology of canonical CCUS technology features being used in different CCUS demonstration facilities, such as the adopted method of carbon dioxide sequestration or the planned industrial use of the carbon dioxide byproduct. They will then select a set of demonstration plants that represent a broad array of different CCUS features to study, conducting semi-structured interviews with a wide range of industry leaders, government representatives, scientists, engineers, and non-governmental actors involved in these projects. Their analysis will focus on the regulatory, institutional, and technological barriers and opportunities that have shaped the development of CCUS technologies to date with the aim of extracting relevant lessons that can be learned as this suite of technologies moves ahead. At the end of the project, the UCSD team will organize a structured workshop to review the research results and share findings with the broader community of researchers and practitioners.
