Salt batteries – the only chemistry UL9540A certified for safety

More and more people are recognising that one of the major issues with energy storage batteries are the dangers with fires and explosions particularly associated with thermal runaway (self-sustaining fires). This has become particularly relevant as people are considering installing the many lithium ion battery technologies in their houses or businesses and are becoming aware of the possibility of the dangers associated with this.

Standards Australia has been working on new installation standards “AS-NZ 5139_2019” which will try and address this issue but there is still a lot of discussion around whether the new installation restrictions are too strict or are really looking at individual battery characteristics correctly and fairly.

International Standard “UL9540A” has been developed to independently examine Fire Risk with Battery Cells and Evaluate Thermal Runaway Fire Propagation in Battery Energy Storage Systems.

Battery storage uptake by households surges as grid costs soar

 

Battery storage systems being installed in Australia look set to confirm earlier predictions that battery installations will treble in 2017.

New data from the SunWiz 2017 Mid-Year Battery Report shows more than 7000 battery installations took place across Australia in the first six month of 2017.  By contrast there were 6500 installations recorded for all of 2016. Current projections say Australia is headed for a total of more than 20,000 energy storage battery installations by the end of 2017.

Problems and Solutions solved with energy storage

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.

Peak shaving to reduce peak demand charges

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.

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%.
