The future of energy storage is inextricably tied to the electrification of transport and the revolutionization of the electrical grid. At scale, these two applications will increase the total global installed energy storage capacity by over an order of magnitude. Designing energy storage technologies for the future must therefore carefully consider the impact such widespread adoption will have on resource demands (e.g. for raw materials) and the environment. StorageX tackles these challenges by bringing together experts in engineering, environmental sciences, and economics to evaluate the resource economics and environmental impact of different energy storage technologies. This understanding provides valuable feedback and guidance for researchers developing new technologies and concepts.
