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.
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.

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 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.
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 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.
