The future availability of rare earth elements (REEs) is concern due to monopolistic supply conditions, environmentally unsustainable mining practices, and rapid demand growth. We present an evaluation potential scenarios for REEs with a focus on the issue comining. Many assumptions were made simplify analysis, but identify some key variables that could affect markets market behavior. Increased use wind energy electric vehicles are more sustainable future. However, since technologies...
Supply disruptions of imported mineral commodities pose significant risk to U.S. manufacturers emerging technologies.
Many authors suggest that market forces are inadequate to successfully manage the problems of resource availability and use. The fundamental question is whether these inadequacies intrinsic or if they arise from a failure firms detect respond subtle signals. This paper explores latter by describing (1) mechanisms can limit materials availability, (2) effects such limits on firm, (3) preliminary metrics diagnose risks, (4) strategies reduce firm's risk exposure. Case analyses two systems used...
Critical materials are resources that vulnerable to supply disruptions, where those disruptions can have significant adverse impacts on society. In the coming years, risks associated with energy transition and geopolitics likely intensify new expected emerge. This perspective identifies three "Grand Challenges" represent frontier areas for critical research highlights some promising directions each area: (1) extending visibility downstream value-added beyond elemental forms; (2) quantifying...
The accelerating adoption of clean energy technologies is driving demand for certain mineral commodities like lithium, essential electric vehicle batteries. Understanding the influence transition on each market requires examining their supply and price elasticities. However, there have only been a limited number studies that estimated elasticities in emerging technologies. We empirically estimate elasticity (PEDs) used lithium-ion battery cathodes anodes—cobalt, graphite, manganese, nickel....
Platinum is an excellent catalyst, can be used at high temperatures, and stable in many aggressive chemical environments. Consequently, platinum current industrial applications, notably automotive catalytic converters, prospective vehicle fuel cells are expected to rely upon it. Between 2005 2010, the industry approximately 40% of mined platinum. Future growth sales shifts toward new technologies could significantly alter demand. The potential risks for decreased availability evaluated,...
Modern technology makes use of a variety materials to allow for its proper functioning. To explore in detail the relationships connecting products that require them, we map supply chains five product platforms (a cadmium telluride solar cell, germanium turbine blade, lead acid battery, and hard drive (HD) magnet) using data ontology specifies chain actors (nodes) linkages (e.g., material exchange contractual relationships) among them. We then propose set network indicators (product...
Secondary mass savings are reductions that may be achieved in supporting (load-bearing) vehicle parts when the gross (GVM) is reduced. Mass decompounding process by which it possible to identify further secondary result reduction of GVM. Maximizing (SMS) a key tool for maximizing fuel economy. In today's industry, most complex parts, require significant design detail (and cost), designed first and frozen while rest development progresses. This paper presents estimating SMS potential early...

Abstract Estimating the material flows of rare earth elements (REEs) is essential to understanding which industries are most vulnerable potential REE supply disruptions which, in turn, may inform policy recommendations aimed at reducing risk. However, REEs a group mineral commodities characterized by highly uncertain estimates and demand due market's complexity, opacity, small size. In this study, streamlined methodology was applied map commodity first‐use final‐use applications estimate...
Mineral commodity supply disruptions have the potential to ripple through and impact economy in many ways. Industrial vulnerability is a crucial component of mineral criticality tools as it provides guidance on economic importance these commodities regional indices. Using an model that links end-use data input-output tables linear optimization routine, reductions output individual industries overall may be calculated. Such can also help identify industries, they direct or indirect consumers...
Materials criticality assessment is a screening framework increasingly applied to identify materials of importance that face scarcity risks. Although these assessments highlight for the implicit purpose informing future action, aggregated nature their findings make them difficult use guidance in developing nuanced mitigation strategy and policy response. As first step selection strategies, present work proposes modeling accompanying set metrics directly compare strategies by measuring...

Platinum group metals, a key material for electronics manufacturers, exhibit characteristics of with high scarcity risk based on Malthusian, Ricardian and structure metrics. This includes potential future demand growth, extraction costs market concentration primary supply. The conditions that impact downstream firms are explored through the use dynamic model. In particular, average spending over period time by is proposed as simple metric to compare relative impacts various scenarios these...
Increased recycling, product redesign and substitution can improve firm resilience in the face of uncertainties materials availability. The delays involved implementing these strategies may result unprepared firms losing market share to competitors who are better prepared address challenges.
