Battery capacity depends on user needs

Posted on by Linda

 

There are many things to take into account when looking at an energy storage battery for your home or business. These include what you want your energy storage battery to do as well as its safety, performance, operating temperature and end of life recyclability.

Unfortunately many people only look at the initial purchase cost of batteries and this is what they use to compare different batteries. This doesn’t take into account what a battery may cost them over its lifetime or the cost to the environment of both the battery’s manufacture and end of life disposal. To make a realistic comparison of a battery’s cost you need to consider it’s full “cradle to grave” impact on all areas, including its safety during operation and it’s environmental impact.

Accelerating Climate Action

Amongst the G20 countries, Australia’s emission reduction target – a reduction of 26-28% on a 2005 baseline – is unusually weak, nowhere near what is required for us to play our fair share in meeting a 2°C Paris target.

The impacts that we are experiencing now at a ~1°C rise in average temperature are the forerunners of rapidly escalating risks as the temperature rises towards 2°C and beyond. An overview of these risks – worsening extreme weather, damage to natural ecosystems, disproportionate impacts on the poor and vulnerable – is given by the ‘burning embers diagram’ of the Intergovernmental Panel on Climate Change (IPCC). The series reveals a striking trend – as the science of climate impacts advances, severe impacts are now expected at more modest increases in temperature

Problems solved with battery storage

Posted on by Linda

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. Continue reading “Problems solved with battery storage” →
