Energy Storage Discussion Thread « BraveNewClimate

Eclipse Now , on 13 November 2011 at 8:50 PM said: //3. If the storage technology becomes cheap, what is to stop baseload plants like coal and nuclear from undercutting renewables, given that they can charge large batteries in low-demand times and then sell the power during peak (high-price) periods?// This is a great point! I was personally quite amazed at the Nullabor seawater dam claims that a 7km diameter 20m deep dam could store enough energy to run the whole of Australia for 10 hours. The author of the paper said it might come in at $2 billion if the base is not concreted… more if it was concreted. http://energy.unimelb.edu.au/uploads/Australian_Sustainable_Energy-by_the_numbers3.pdf Let’s call it $3 billion with concrete. That’s still cheaper than many baseload nuclear power plants, and how many of those would we need to run the *whole* of Australia for 10 hours? So...
