Critical Materials

Clean energy technologies have been developed to address the pressing global issue of climate change; however, the functionality of many of these technologies relies on materials that are considered critical. Critical materials are those that have potential vulnerability to supply disruption. In this paper, critical material intensity data from academic articles, government reports, and industry publications are aggregated and presented in a variety of functional units, which vary based on the application of each technology. The clean energy production technologies of gas turbines, direct drive wind turbines, and three types of solar photovoltaics (silicon, CdTe, and CIGS); the low emission mobility technologies of proton exchange membrane fuel cells, permanent-magnet-containing motors, and both nickel metal hydride and Li-ion batteries; and, the energy-efficient lighting devices (CFL, LFL, and LED bulbs) are analyzed. To further explore the role of critical materials in addressing climate change, emissions savings units are also provided to illustrate the potential for greenhouse gas emission reductions per mass of critical material in each of the clean energy production technologies. Results show the comparisons of material use in clean energy technologies under various performance, economic, and environmental based units.

Abstract Institutional capacity is enabling environment for interactions between individuals and organizations. Understanding the changes required regarding the institutional capacity is needed to remove barriers and stimulate transition to sustainable energy systems. The aim of this study was to identify those barriers to understand what type of changes of the institutional capacity is required. Review of publications was done with focus on the three critical domains for clean energy transition – social acceptance, climate and energy policy and critical materials. In result, the most important aspects of the institutional capacity that form the barriers as well as stimulus in the three domains were identified. Causal loop diagram providing a systemic viewpoint on the important elements and interactions within the mentioned three domains is presented. Results of the study can be used for system dynamics model of energy transition.
