Medical Centre – Commercial Case Study using SoNick batteries

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.

A space was identified under the stairwell as the only realistic place to house the batteries and inverters. This limited the type of battery storage due to both space and safety requirements. Continue reading “Medical Centre – Commercial Case Study using SoNick batteries”

Why is energy storage pushed as needing an ROI

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 and the FZSoNick battery

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.

NASA robot catches fire

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.

A number of attempts were made to put out the fire but eventually the robot was wheeled outside and allowed to burn itself out.

Climate of the Nation 2017 Australian attitudes on climate change

 

 

  1. 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 %).
  2. 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 %).

Redflow welcomes safety-first fire rules for batteries

 

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.

Along with GridEdge and many other non-lithium battery companies Australian battery company Redflow Limited (ASX:RFX) has welcomed proposed new regulations that prioritise fire safety for the deployment of lithium-based batteries inside homes.

What is a Molten Salt Battery

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.

SoNick battery BMS or Battery Management System

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”

Fire risk for solar and batteries

Victoria’s Metropolitan Fire Brigade says it may take “Years to understand’ the fire risk posed by lithium ion battery storage

 

The MFB said the solar installations were vulnerable to faults across their systems, including isolation switches, inverters and installed wiring, and from deteriorating components.

The alarming figures come as the solar battery storage industry pushes to kill new regulations that would force homeowners to build a separate “fire bunker” housing for battery installations.

Under draft rules released by Standards Australia, lithium ion batteries are classed as “Fire Class 1” and would not be allowed inside or within 1m of a domestic dwelling. The industry will have until August 15 to respond to the draft regulations.

The safety moves are designed to avoid a repeat of Labor’s insulation batts scheme in which the rapid rollout of roof insulation in 2009 led to more than 200 house fires across the nation, and ultimately four deaths. Continue reading “Fire risk for solar and batteries”

Battery Standards and Lithium battery fires

It is interesting that everyone is up in arms about the battery standards being introduced into Australia but maybe people should be asking why these standards are being brought in. It is not only government and coal company lobbying.

Yes, lithium ion batteries are currently cheaper and installing them in safer locations will add cost to installing them, however there are already safer battery technologies on the market that are being pushed out of the market due to the cheap cost of lithium ion batteries.

It is easy to say there is a low probability of your lithium ion battery catching fire, (and some lithium battery technologies are safer than others), but if it is your house that burns down or someone in your house that is injured you may be taking a different view on the safety standards.

The thing that is not being addressed here is that a fire doesn’t have to start in the battery due to a fault in the battery for the battery to catch fire; it can start in the vicinity of the battery and then move to the battery. The standards are designed to help the fire brigade protect your property and their members safety by limiting the dangers caused by battery fires that can’t be put out.
