| Abstract |
The decarbonisation of the energy system is at the forefront of government policy as we transition into a low carbon economy consistent with maintaining global warming below the 1.5-2 degrees C limit determined by the Paris Accords. By allowing increased penetration of renewables, thus increasing the amount of renewable energy which can be utilised, one potential technology which is able to assist the decarbonisation of both the electricity and process heat sectors is high temperature thermal energy storage (TES). In addition to providing a source of energy storage, these systems can utilise waste-based products from other industries such as steel making, asbestos processing, combustion, potash production, mining and minerals processing, or glass recycling as the storage media. The usage of such materials can not only be cost-effective, but also increase sustainability to further their participation in a circular economy which is crucial to reduce our dependence on virgin materials. Therefore, the current study aims to provide an overview of the available materials which could be utilised for high temperature thermal storage between 200-750 degrees C. |
