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

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.

GridEdge is a company that delivers both off grid and on grid energy supply to all levels of consumer demand.
GridEdge has the Australian and New Zealand distributor rights to the FZSoNick sodium nickel chloride battery which has superior operating capabilities, compared to any other battery technology, currently available. The SoNick battery operates at a wider range of temperatures compared to other batteries and has the advantage of being a non-toxic, environmentally friendly battery that is much more compact, compared to many other batteries set up currently on the market or proposed in the near future.

- 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 %).

Across Australia, extreme weather events are projected to worsen as the climate warms further.
Extreme heat is projected to increase across the entire continent, with significant increases in the length, intensity and frequency of heatwaves in many regions.
The time spent in drought is projected to increase across Australia, especially in southern Australia. Continue reading “How will Climate Change affect Australia?”
Recent sub zero temperatures in Victoria have caused problems with liquid in solar panels and batteries freezing.
Plumbers and solar installers say they have struggled to keep up with unprecedented demand for help as temperatures plummet. Cold weather can cause water in solar panels to freeze and expand, resulting in snapped and split panels and broken frost valves. Naturally this problem is worse in cheaper products or products that aren’t installed properly to allow for temperature extremes.
We have also heard of several instances of batteries freezing as well. Most lead acid and lithium ion batteries only operate effectively between around 5 – 35 to 40 °C which is problematic on days when the temperature gets very cold or even is below freezing as we experienced in Melbourne recently.

Energy storage batteries come in a variety of different sizes and weights and each have different characteristics. Here is a comparison of some of the most common batteries currently available in Australia with comparisons of size for a similar sized 20kWh system. You can see from this image that size is not necessarily a good indication of the power that is available to be used in a battery installation. Some batteries have much better energy density than others with the FIAMM SoNick battery having the best energy density of all, although some of the newer lithium ion batteries also have a very good energy density..
If you have a lot of suitable space to store your battery this may not be relevant but if you are limited in space you may want to consider one of the more energy dense batteries. If there is a possibility of moving house you may want to take into account the battery size as well as its weight if you want to move it with you. Continue reading “What is your Energy Storage Battery Size?”
Most batteries will operate, with varying degrees of effectiveness in the 5- 35 °C range so are fine for the autumn and spring operating months, however if you want a battery that will also operate efficiently in winter and summer you need to understand how temperature has an effect on a batteries operating capabilities.
The ambient weather temperatures have a large impact on the performance and on the life of most batteries and unfortunately, it’s a characteristic that isn’t often talked about.
The optimum temperature for most batteries to operate at is around 25°C and this is the temperature all battery testing is performed at. When temperatures vary, either up or down there is an effect on the performance and life of most batteries. Continue reading “Battery Operating temperatures”
Energy storage batteries come in a variety of different sizes and weights and each have different characteristics. Here is a comparison of the degradation after 10 years of batteries currently available in Australia with comparisons of size for a similar sized system from other battery technologies.
You can see from this image that different battery technologies have different degrees of degradation over their lifetime. You need to take this into account when deciding the best battery for your needs. If a battery seems cheaper to purchase upfront but has then degraded significantly after a couple of years and may be down to only 50 or 60 % of original capacity after 10 years this will significantly affect how much power you can draw from that battery.
This degradation is also what may make it difficult to add additional batteries to an installation after a few years. In many cases with lead acid and lithium ion batteries you may need to purchase a new system if you want to add extra capacity. Continue reading “Battery degradation”
Climate change is increasing the risk of bushfires in Victoria and lengthening fire seasons.
- Extreme fire weather has increased since the 1970s in the east and south of Australia, including Victoria, with the fire season length extending from October to March.
- Climate change is now making hot days hotter, and heatwaves longer and more frequent. Drought conditions have been increasing in Australia’s southeast.
- Climate change is driving an increase in dangerous fire weather, which in turn is increasing the frequency and severity of bushfires.
