RedFlow’s Zinc-Bromine battery: A breakthrough technology to boost uptake of renewable solar

RedFlow’s new kilowatt-scale batteries have been hailed as a critical enabling technology that allows easy integration of large numbers of small solar generators into the electricity grid. The RedFlow systems also put Australia in front of the rest of the world in being ready for the so-called ‘Smart Grid’, which is how electricity will be provided in the future.

RedFlow CEO Chris Winter, speaking on the eve of the annual conference of the Australian and New Zealand Solar Energy Society in Townsville, said, “RedFlow is delighted to be involved in this ANZSES solar generation conference. Delegates will have a chance to see our energy storage systems in action, using solar energy stored during the day to power an evening party on a beach on Magnetic Island.

Here in Queensland, we are now manufacturing our high performance systems which are an ideal match with Solar generation. This means that electricity generated from daytime sunshine can now be efficiently captured and used in evening peak times when power companies often struggle to meet electrical demand”.

The core of RedFlow’s patented technology is their zinc-bromine battery module.

At just 220kg, it has a 10 kWh capacity – enough to run a typical household for many hours.

“You’d need about one and a half tonnes of lead-acid batteries to do the same job, and our battery is much more environmentally benign as it does not use toxic heavy metals like lead” Mr Winter said.

“In 2010, we will begin expanding our manufacturing capacity to meet the expected huge global demand for smart-grid storage systems. RedFlow plans to be one of the largest manufacturers in the world for this application, on the back of our cutting edge technology and superior systems integration”.

Upgraded Zinc-Bromine Battery Capacity

RedFlow Technologies Ltd (RedFlow) is pleased to announce that its ongoing design optimisation program is continuing to deliver good results.

RedFlow’s engineering team is continuing to work on techniques to improve the performance and reduce the production cost of its proprietary zinc-bromine battery.

The latest optimisation has increased energy storage capacity by approximately twenty per cent. Tests at the company’s Seventeen Mile Rocks facility in Brisbane last week showed the new generation zinc-bromine stack is capable of delivering over 13 kWh of energy in repeated cycling tests. This compares with the nominal 10.5 kWh rating of the current generation RedFlow battery.

Commenting today, RedFlow’s CEO, Mr. Chris Winter said “The latest round of improvements show that the ongoing development path we have is delivering great results. The new generation battery has approximately 20 per cent more capacity than the prior generation, while retaining high efficiency and capacity for 100% discharge.

Mr Winter said “As a consequence, RedFlow has more than achieved a 20% reduction in its cost per kWh, as the new generation battery incorporates other cost–saving features. We will be moving to progressively implement the new design into our production operations.

RedFlow’s advanced design is packaged in a module of approximately 230 kg. An equivalent set of lead-acid batteries would weigh 2,200 kg (when operated in an equivalent daily cycling mode, and limited to 20% depth of discharge to ensure an acceptable operating life).

If you have any questions on the above, I will be pleased to assist”.

Advanced Remote Area Power Supply New Development Contracts

RedFlow Technologies Ltd (RedFlow) is pleased to announce that it has signed an additional development contract with Ergon Energy Corporation for demonstration of advanced remote area power supply systems.

Remote area power supply systems (RAPS) are common in Australia’s rural locations which are too distant to have connection to the electricity grid. Currently, most RAPS rely on a mix of diesel generation, solar PV, and lead-acid batteries.

With increasing fuel prices, high maintenance costs and carbon emissions, diesel generation is becoming less attractive.

Solar PV, while cheap to operate, suffers from non-availability at night-time or in poor weather. Lead-acid batteries are usually used to overcome this intermittency, but suffer from high cost and weight, and relatively poor reliability.

The preferred advanced RAPS system uses solar PV combined with high performance batteries such as RedFlow’s zinc-bromine storage systems. This type of RAPS combines 24/7 availability with low operating cost, and excellent environmental credentials.

There are two elements to the new demonstration program with Ergon Energy signed today:

  • A Remote Terminal Unit (RTU) to interface with selected inverters and provide communications; and
  • A zinc-bromine battery optimised for RAPS applications.

 

As part of the contract, there will be field trials at two existing Ergon Energy sites.

Commenting today, RedFlow CEO Mr. Chris Winter said “We are pleased to be working with Ergon Energy on this program. It provides another opportunity to demonstrate that RedFlow’s zinc-bromine batteries are the most cost effective solution for RAPS applications. Moreover, solar PV generation combined with battery storage has zero carbon emissions and is clearly the way of the future for RAPS”.

Mr Winter added “There is strong demand for better RAPS products throughout Australia, and globally. The product we demonstrate here with Ergon Energy will pave the way for international sales in future years. Already Australian  companies have a strong reputation internationally within the renewable energy industry and this collaboration will help enhance that.”
