Storing renewable energy in the world’s biggest batteries

Is it possible for wind and solar to supply reliable, dependable electricity day or night, regardless of the weather? One of the biggest criticisms of renewable energy has been the simple fact that the output of wind and solar farms can vary depending on the weather and time of day. When renewables made up a small part of the generation mix, that variability wasn’t a big problem. But as wind and solar do more of the heavy lifting, it is vital that we find ways to store energy for those times when less energy is being generated. In this episode of ReWired: Solving the Energy Puzzle, we look at one of the newest - and most headline grabbing - large-scale storage technologies. Just like the AA cells that historically powered devices like transistor radios, massive battery banks today store energy in electric vehicles and increasingly offer a way to support the electricity grid. Hear Edify Energy CEO John Cole tell us about the 25 MW / 50 MWh battery they have installed alongside their solar farm at Gannawarra in northern Victoria.  Australian Energy Market Operator CEO Audrey Zibelman shares her perspective on the role storage technologies like batteries have a role to play 'firming' the variable output of wind and solar farms, and helping to keep the lights on. We also hear from Climateworks CEO Anna Skarbek, who believes that batteries will be an important part of the future energy portfolio. She shares her belief that flagship projects like the Hornsdale Power Reserve in South Australia provide a glimpse of the future and help to shift the conversation around the energy transition.
