Long-duration storage is key to Australia’s energy security Recent disruptions to the Strait of Hormuz are a reminder of a simple fact: energy markets reprice risk quickly. In Australia, this pain is initially felt in transport and parts of industry that rely on imported liquid fuels, with prices set offshore and supply chains we do not control. Reducing that risk exposure depends on accelerating electrification of those sectors, where it is economic to do so.
