While „barracking“ for renewables has obvious attractions, it’s no use „pretending“ batteries are the solution to energy storage, according to Sky news host Chris Kenny.
„Energy storage is the problem with renewable energy, it’s the only issue really, the big one,“ Mr Kenny said.
„But these politicians and commentators think there’s already some king of big battery nirvana.
„Now there are plenty of people barracking for renewable energy, good on them, it’s a free world and renewables of course have lots of obvious attractions.
„But it is no good pretending that batteries are the solution. You can’t run an electricity grid on make-believe.“
Mr Kenny also spoke with Nationals Senator Matt Canavan who said the question of battery energy storage for windfarms should not be „how much do you need“, but rather „how much of the year“ can you accept the power to go out.
„It’s not as easy to say well how much do you need as backup, what you need to say is how much of the year will you accept the lights going out,“ he said.
„Because you could have no wind power for weeks, for months – it’s very variable. But you’ve got to decide what risk you’d wanna accept.“
