随着全球南方国家的经济增长和发展加快，以及对新能源技术的需求扩大，矿物与能源之间的关系变得越来越重要，而与此同时，各种重要矿物的品位和传统采矿的可用储量正在下降。目前正在广泛研究深海沉积物和城市矿石等非常规资源，但开采仍然有限。本文探讨了向清洁能源未来过渡的一些影响，同时通过传统矿石的下降和非传统矿产资源的吸收的转变。三种能源情景，每一种都有三个可再生能源的吸收水平，评估了关键矿物在12种替代矿物供应模式下限制增长的潜力。研究表明，在每单位容量的材料强度稳定的情况下，硒、铟和碲可能成为薄膜光致发光材料扩展的障碍，而钕和镝可能会延迟风力的传播。对于燃料电池，没有观察到限制。
The nexus of minerals and energy becomes ever more important as the economic growth and development of countries in the global South accelerates and the needs of new energy technologies expand, while at the same time various important minerals are declining in grade and available reserves from conventional mining. Unconventional resources in the form of deep ocean deposits and urban ores are being widely examined, although exploitation is still limited. This paper examines some of the implications of the transition towards cleaner energy futures in parallel with the shifts through conventional ore decline and the uptake of unconventional mineral resources. Three energy scenarios, each with three levels of uptake of renewable energy, are assessed for the potential of critical minerals to restrict growth under 12 alternative mineral supply patterns. Under steady material intensities per unit of capacity, the study indicates that selenium, indium and tellurium could be barriers in the expansion of thin-film photovoltaics, while neodymium and dysprosium may delay the propagation of wind power. For fuel cells, no restrictions are observed.
