Powering the new economy with clean energy
Many households and businesses already attach battery storage to their clean energy systems. Now is the time to grow the industry, encourage the take-up of storage and help make Australia a renewable energy leader. With public interest high, now is the time for a targeted, five-year support package to drive down costs and put battery storage in reach of every household and business.
Battery storage can reduce network peaks and troughs by storing electricity during off-peak times and discharging it during the peak. Continue reading “Focus on the Solution – Not the Problem”
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.

For many businesses it is important to look at using battery storage to reduce peak demand charges. Often, even one large energy spike can greatly increase total energy bills with this drawdown increasing the energy charge for all power usage. If the peak demand needed can be reduced then the overall electricity charges can be reduced.
Peak demand usually occurs when several high energy using pieces of machinery come into use at the same time, particularly if this machinery has large initial starting energy draws.
Peak demand is usually calculated based on the highest 15 minute average usage over a given month, even if it only occurs once a month (some energy retailers actually use the maximum usage over a yearly period, again even if this maximum only occurs once a year). These demand charges are also often charged on a tiered scale with higher charges the higher the peak is.

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.

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. Continue reading “GridEdge and the FZSoNick battery”
- 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 %).

Molten Salt Battery
When it comes to green energy, the intermittent nature of renewable sources like wind, solar, and tidal power presents a difficult problem for the electrical grid management. Peak energy production often doesn’t correlate well with peak energy demand, necessitating a means of storing excess energy when consumption is low. As renewable energy sources become more prevalent, and the need to curb fossil fuel emissions continues to increase, finding a new grid energy storage solution has never been more important. It is the final piece of technology required to bring about wide scale adoption of renewable energy sources like solar panels and wind turbines.
- What is a Molten Salt Battery?
Molten salt batteries, especially liquid metal batteries, are increasingly gaining interest from the energy community as a grid energy storage solution for renewable energy sources. Combining high energy and power densities, long life times, and low cost materials, they have the potential to meet the unique demands of grid scale energy storage. A molten salt battery is a class of battery that uses a molten salts electrolyte. The components of molten salt batteries are solid at room temperature, allowing them to be stored inactive for long periods time. During activation, the cathode, anode and electrolyte layers separate due to their relative densities and immiscibility. The molten salt layer in the middle serves as an electrolyte with a high ionic conductivity, and is the medium through which the ionic species travel as the battery charges and discharges.

Some Energy storage batteries have a built-in BMS or Battery Management or Monitoring System to monitor how a battery operates and how it talks to the grid. This is an electronic system that manages a batteries function by protecting the battery from operating outside its “Safe Operating Area” both for the batteries health and to prevent any accidents that the battery could cause by malfunctioning.
The internal BMS monitors and controls all charging and safety aspects of the battery. The BMS will also keep you informed of the state of the battery so you can monitor the batteries health.
When integrated with other SoNick batteries the SoNick BMS synchronises the operation of the battery bank so that all batteries work together as one large battery. Continue reading “SoNick battery BMS or Battery Management System”
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.
