Battery storage uptake by households surges as grid costs soar
Battery storage systems being installed in Australia look set to confirm earlier predictions that battery installations will treble in 2017. Continue reading “Creating Energy Independance”
Amongst the G20 countries, Australia’s emission reduction target – a reduction of 26-28% on a 2005 baseline – is unusually weak, nowhere near what is required for us to play our fair share in meeting a 2°C Paris target.
The impacts that we are experiencing now at a ~1°C rise in average temperature are the forerunners of rapidly escalating risks as the temperature rises towards 2°C and beyond. An overview of these risks – worsening extreme weather, damage to natural ecosystems, disproportionate impacts on the poor and vulnerable – is given by the ‘burning embers diagram’ of the Intergovernmental Panel on Climate Change (IPCC). The series reveals a striking trend – as the science of climate impacts advances, severe impacts are now expected at more modest increases in temperature

There are a variety of reasons that people choose to make use of battery storage. In the domestic market the most common ones are to reduce the price they are paying for ever increasing electricity costs by shifting power from their solar panels collected during the day to when it is needed at night.
There are many other people for whom the desire to be energy independent is the driving force, even if they still stay connected to the grid. This may be because of dissatisfaction with treatment from power companies or due to an unreliable supply. Continue reading “Why will I choose energy storage batteries?”

Australian States are powering ahead on climate targets despite federal inaction
Australian states and territories are powering ahead, developing policies that will meet the federal government’s internationally agreed greenhouse gas emission targets, with South Australia, the ACT and Tasmania leading the race.

One of the biggest problems with the efforts to use renewable energy to produce large amounts of the energy consumed on a daily basis has been its inability to reliably supply power at the times it is most needed. This can and will be addressed with the installation of battery systems that allow households, businesses and energy network providers to store renewable energy for use at night or in peak periods.
Solar panels convert the sun’s rays into electricity during the day with maximum generation being between the hours of 11 to 3pm. Unfortunately, for most people unless you are home during the day 80% of this power gets fed back into the grid for very little return. Likewise, although energy generation through wind is now very efficient and cost effective the times when wind produces energy can be intermittent.
Batteries also reduce the amount of electricity that is exported to the grid from rooftop solar during the middle of the day. This has the capacity to significantly reduce variability and stabilise grid supply. Continue reading “Problems and Solutions solved with energy storage”
Before purchasing any battery storage it is critical that you understand what you want to do with the battery. If you only want to shift some energy generated from your solar panels during the day to be used at night and don’t mind if you don’t have power when the grid goes down it isn’t as critical that your battery needs to be able to provide all the power you need.
However, if you want to be energy independent and want to have power in times of power outages (as most people do that purchase batteries) then you need a battery that is capable of running your house for a period of time. You need to consider your appliances and what you consider essential and determine what power will be drawn down by all of them. As can be seen in the above image you may need multiples of some battery technologies to accomplish this which may greatly increase the cost of an installation.

Why is energy storage pushed as needing an ROI but water tanks are sold to help the environment.
It is interesting that many people looking at battery storage look on it as an investment with a ROI when this philosophy isn’t used for any other household appliances. Nobody ever asks what is the ROI of a fridge or a car.
When water shortages are an issue, people are encouraged to purchase water tanks to supplement water storage supplies, however there is never mention of ROI for these, possibly because if water tanks were purchased to reduce the cost of water rather than to protect the environment they would never pay for themselves. Continue reading “Why is energy storage pushed as needing an ROI”
- Climate Change: The majority of Australians agree that climate change is occurring (71 %) and accept the scientific consensus that human activity is the main cause (57 %).
- Action: The majority of Australians want Australia to address climate change because they see strong economic, environmental and social benefits and opportunities in the shift to a clean economy (73 %).

Energy storage batteries come in a variety of different sizes and weights and each have different characteristics. Here is a comparison of some different battery technologies currently available in Australia with an indication of the amount of power that can be drawn down.
You can see from this image that size is not necessarily a good indication of the power that is available to be used from a battery. Some batteries have much better energy density than others.
Another thing to consider is how much power you can actually draw from the battery at any point in time. Our SoNick battery can draw 150 amps for 4 hours continuously but some other batteries are very limited in the amount of power that can be used, maybe only with enough to boil a kettle and little more.
