The Tesla Victorian big battery fire at Moorabool near Geelong in Victoria is another example of why smaller community-based neighbourhood batteries are a preferable way forward for making the energy supply more renewable. With smaller installations that are more spread out and serve the community in which they are based there is less likelihood of larger electricity supply interruptions when a large power supplier has issues and has to be taken off line for safety reasons.
The 300MW/450MWH capacity big battery comprised of Tesla batteries in multiple shipping containers was registered with AEMO on 28th July 2021. During testing on 30th July 2021 one cell failed and caught fire and quickly engulfed the container in which the batteries were housed. This then spread to another container which was also destroyed. Luckily fire fighters were able to keep other containers cool enough so that they didn’t also catch fire. The blaze was finally extinguished 4 days later. 150 firefighters and 30 fire trucks and support vehicles attended the fire along with many other multi-agency specialists.
The medical centre was to be refurbished and part of the upgrade was to install a PV system with battery storage. The difficulty was allocating the space for battery storage that was safe for patients as well as staff. As is usual in a medical centre space is a premium and is used for medical related purposes as a priority.
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.

On June 14, 2016, four researchers at the NASA Jet Propulsion Laboratory were preparing to ship a waist-high, ape-like robot named RoboSimian off-site. The robot had been built to rescue people from dangerous situations that were to difficult for human rescuers. The scientists swapped one lithium-ion battery for a fresh one, then left for lunch to let the new power supply charge.
Unfortunately, the new lithium ion battery malfunctioned and went into thermal runaway. Luckily the researchers were no longer in close proximity to the robot so no-one was hurt, although NASA have said there have been a number of these close calls.
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 %).
Just like GridEdge’s sodium nickel chloride battery technology Redflow’s flow battery is well suited to Australia’s varying weather conditions and doesn’t have the fire risks that lithium ion batteries do.
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.
