So much conflicting information on battery storage


When consumers go online to compare different batteries there is so much conflicting information available it is very difficult to get a clear picture of what is available and to understand what is happening in the industry. What is important is you compare similar products and don’t just listen to what salespeople are telling you.

If a product has been in use for a number of years the quoted figures are more likely to be reliable than if a product is new and hasn’t yet been tested in real life conditions. Generally batteries are tested in factories at 25 degrees. This can produce different results than are experienced in real life when temperatures vary widely.

Currently there are no relevant battery standards in Australia as the current battery standards only really apply to lead acid batteries which have been the main energy storage batteries available until quite recently. This means companies that are trying to sell you batteries can make any claims they like regarding depth of discharge and numbers of cycles of their new batteries. This is why you will find very different claims from the same batteries.

It is important that when looking at ROI or “return on investment” that people take into account all factors of the lifetime cost of any renewable energy system, including energy storage. This has to include environmental and health costs both with the production of the battery and the end of life recycling (not only in Australia but overseas as well).

If you are looking for reliable information it is a good idea to look at battery technologies that have been around for a while and have results based on real life testing, such as our SoNick batteries that have been used in installations worldwide since 2006.

The Australian Energy Storage Council or ESC which is the peak body for monitoring battery storage in Australia is working on a new “battery storage guide” where many features are taken into account including safety, performance, operating temperature as well as recyclability and environmental impact. It looks like our sodium nickel chloride (SoNick) or molten salt battery will be the only battery in the top category.
