The potential scale of future demand in Australia ranges from 10,000 tonnes, to stabilise the electricity network, to 2.5 million tonnes for security of the gas network or for potential export. This means we need around 5 million tonnes of storage capacity for a fully developed hydrogen industry. We assessed the options for
The technology for CAES has been demonstrated at several locations worldwide and we think the geology is suitable in several areas of the UK to support schemes in the UK. These properties mean that large voids in the subsurface can be created by solution mining, resulting in storage space that is gas-tight and suitable for
By modifying underground spaces of abandoned coal mines into underground pumped-storage power stations, it can realize the efficient and reasonable utilization of underground space, and at the
Underground Thermal Energy Storage is well suited to district energy systems, where thermal energy is transferred trough piping networks for heating and cooling. Adding a thermal energy store increases the thermal capacity of district energy systems, improves energy efficiency and resiliency and benefits system operators and
