Voters say yes to renewables says Essential Research Australian poll

 

 

A recent Essential Research Australian poll found that almost two out of three people agree that more renewable energy is the solution to future energy needs, and a similar amount approve of Labor’s 50 per cent renewable energy target. In other significant findings 71 per cent think the Federal Government is not doing enough to ensure affordable, reliable and clean energy for households and businesses and 45 per cent blame blackouts on failures of the energy market during extreme weather.

Climate change: 60% (up 6% since December) agree that climate change is happening and is caused by human activity and 25% (down 2%) believe that we may just be witnessing a normal fluctuation in the earth’s climate. By age groups, those aged under 35 split 70%/15% and those aged 55+ split 47%/40%. People with higher education were more likely to think climate change is happening and is caused by human activity – those with university degrees split 72%/19%.

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.

Molten salt energy storage for South Australia

South Australia approves 150 MW concentrated solar thermal plant

Although , using molten salt,  this is a different technological process to our SoNick, sodium nickel chloride batteries but adds credence to the benefits of using molten salt as a storage medium for batteries. Unlike the lithium batteries that are so popular at the moment molten salt batteries are non-toxic, cannot catch fire and go into thermal runaway and are recyclable at end of life with current processes not hopefully at some time in the future.
South Australia approves 150MW concentrated solar thermal plant

South Australia has made a commitment to concentrated solar thermal, the towering clean energy storage solution seen by many as a serious contender for utility-scale moderator as intermittent sources of energy replace coal and gas generation.

The Aurora Solar Energy Project located in Port Augusta, about 300km north of Adelaide, will incorporate eight hours of storage or 1,100 MWh, allowing it to operate like a conventional coal or gas power station. Continue reading “Molten salt energy storage for South Australia”

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”
