3 Why Energy Storage is hot "It's the end of energy and transportation as we know it, and it's coming very quickly, "It's going to be over by 2030; it has started already. "This is not an energy transition. This is a technology disruption." Tony Seba, Stanford University Lecturer, SMH 24/5/2016 So 1.4 million households in Australia have solar panels at the moment. If we add batteries to those households, they, together, will make up the biggest power station in our system Luke Osborne, Reposit, ABC Catalyst Feb 2, million houses on the National Electricity Market (NEM) will install batteries by Morgan Stanley report, Reneweconomy 20 May

18 Standards: Australian Context 7 Key Findings 1. There is a lack of knowledge on the variety of energy storage technologies, and thus on how to care for and operate them in a safe manner in the domestic and small commercial scale context. 2. There is currently no consensus on the appropriate method to extinguish a lithium battery storage fire in the event of an incident. 3. There is insufficient accreditation and training to support and provide qualifications for designers and installers of energy storage systems. 4. Emergency response teams (fire brigade, police and ambulance) have limited education about the issues related to an energy storage technology in the event of an incident. 5. There is a lack of standards for battery storage system disposal and recycling (except in the case of lead-acid batteries). 6. Australian standards for battery energy storage and connection to the electricity network are incomplete. 7. Stationary energy storage installations and incidences are insufficiently reported. 18
