Three questions if I may:

1.  Can AGL advise on the sizes of the larger batteries contemplated and to be realeased at a later date (i.e. how much larger than 7.2 KWh)

2.  What is AGL thinking around providing storage for customers with 3 phase requirements?

3.  Is AGL wedded to lithium ion or other lithium derivatives, or for example flow batteries for commercial / industrial customers with larger loads?

Thanks for getting in touch. Here are some answers. 

1. AGL will be able to supply batteries at any scale to suit the needs of the customers. 7.2kWh is just the start, later in the year we will have offerings at larger sizes and will be able to supply our largest customers with batteries into the MWh scale if need be.
2. Batteries for 3-Phase are on the roadmap and will be available sometime in the first half of next year, if not before. 
3. Lithum-Ion is our primary focus as, at the current time, it offers the best cost-performance profile for the widest range of applications. We are constantly revieing the technology landscape and are always open to alternatives to other technologies as they become viable for specific applications.

I run a high-purity silica mining and exploration operation in Southland New Zealand. I have been in contact with professor Alan Brent at Victoria University who put me on to liquid silica renewable  energy storage units. Southland silica Ltd has status having recently been invited to enter the Callaghan Innovation C-Prize environmental awards. Callaghan Innovation is a government think tank that advises cabinet on a variety of scientific issues relating to national policy. During periods of excess renewable energy production the liquid silica can be superheated from 1,500 degrees to 2,500 degrees. When the grid requires peak demand the superheated silica can be passed through a heat exchanger to drive conventional steam driven turbines for electricity production. Perhaps it is possible to upgrade out dated coal-fired power stations to liquid silica renewable energy storage units. Rio Tinto are intending to close their Tiwai Point aluminium smelter. This facility receives it's renewable energy from the adjacent Manapouri power station which produces 15% of New Zealand's electricity. Southland Silica Ltd is looking for management and capital to upgrade it's current operation to provide the feedstock to a refinery of silicon metal at Tiwai Point for photovoltaics and renewable energy storage units.
