It’s a big call for what is currently a pretty small concern – the company, as noted above, was only fairly recently spun out of the University of Sydney, and notched up its first fund-raising in 2016 with a $11 million investment by UK renewables group Armstrong Energy. “I start off with an empty battery with zinc ion, with two positive charges on it, plus two bromide ions, so that’s electrically neutral – that’s your zinc-bromide salt,” he says. And that market will only grow.”, Will they be moving into the utility-scale market? With the help of a new $10 million fundraising round – also launched on Wednesday night – Gelion expects to be mass producing its zinc bromine gel battery technology for applications ranging from residential to grid, at a cost of below $100/kWh by the end of 2021. “Their safe battery technology (is) hidden in the pole structures, and that will deliver solar power all night long – it’s very exciting,” adds University of Sydney vice chancellor and principal, Dr Michael Spence. “One of our key philosophies is never to talk down any other product,” he starts by saying, “but flow batteries in general are just more complex, because they have moving parts. “Applications will range from anything where other battery technologies are more combustive,” Fitzpatrick adds. Sophie has been writing about clean energy for more than a decade. “Our estimates are, that when we’re mass producing, that will be the price,” said Gelion CEO, Rob Fitzpatrick, referring to the production cost for the battery cell component, only. According to Fitzpatrick, Gelion is currently in “a number of advanced conversations with all of the major commercial construction companies in Australia,” but not in a position to talk about them publicly yet. “I got the power!” Take a look inside the base of our solar powered lighting tower. For easy remote access (Gelion is owned by Gelion UK, a joint venture between management and Armstrong Energy, who oversee the corporate governance and funding of the business, as well as assisting in long-term strategic planning.). “Where we’re focusing first is at the larger end,” says Fitzpatrick. “A remarkable feature of our patented nanostructured gel is that it can deliver a slow and steady discharge, or a fast capacative type of discharge, depending on the thickness of gel and battery architecture. To further reduce self-discharge and to reduce the vapor pressure of bromine, complexing agents are added to the positive electrolyte. In the zinc–bromine flow battery the negative electrode reaction is the reversible dissolution/plating of zinc: At the positive electrode bromine is reversibly reduced to bromide (with a standard reduction potential of +1.087 V vs SHE): The measured potential difference is around 1.67 V per cell (slightly less than that predicted from the standard reduction potentials). However, it is rather stable in contact with neutral and alkaline aqueous solutions. “Grid-scale applications come in all sizes, and the ability to have stability on the grid is exactly what this sort of thing will target.”. That salt is dissolved in water to make an electrolyte. Zinc–bromine batteries use a liquid to transport the changed particles, which makes them unsuitable for mobile use. “Building off the experience of working with University of Sydney … the biggest draw is coming from commercial-industrial and solar farm applications. Ions can move quicker, decreasing charging time. As of April 2016 , Gelion, which is the spin-off company of Sydney University, is developin… Soc. With the help of a new $10 million fundraising round – also launched on Wednesday night – Gelion expects to be mass producing its zinc bromine gel battery technology for applications ranging from residential to grid, at a cost of below $100/kWh by the end of 2021. The technology was unveiled as part of a $1 million contract with the University – the company’s first such commercial deal – which starts with the installation of battery integrated solar light poles across the Sydney campus, followed by plans to add storage to the Uni’s rooftop solar systems. This market is not that. ZBM2s are easy to deploy in scalable parallel clusters for high availability, high scale deployments at the largest sites. 100% depth of discharge capability on a daily basis. The brainchild of Professor Thomas Maschmeyer, who first tested his idea for a non-flow zinc bromine battery using “two pieces of carbon paper covered in gel, stuck together with some wooden washing pegs and some silver solder wire”, Gelion Technologies today delivered six solar-panel-shaded tables with benches on the University of Sydney’s Camperdown and Darlington campus. Beyond that, the company has ambitions in almost every sector of the burgeoning global battery storage market, which it notes is currently valued at between $60bn-$70bn. During charging, zinc is electroplated onto conductive electrodes, while at the same time bromine is formed. In terms of home solar storage, the only commercially available zinc-bromine battery on the market currently is Redflow’s Zcell, specifications of which are listed on SQ’s solar battery comparison table. 127(3), 528–32 (1980), Handbook of batteries, 3rd edition. Indeed it is this quality of the zinc bromine chemistry – which mimics some of the attributes of fire retardants – alongside the scalability of the gel batteries, that has attracted the attention of Australia’s construction industry. “It can’t blow up, it cant catch fire – and if the house burns, the battery is the last thing that will burn, not the first,” says Fitzpatrick. “The biggest challenge with this sort of technology is being 10 years ahead of the curve. On discharge, the reverse process occurs: the metallic zinc plated on the negative electrodes dissolves in the electrolyte and is available to be plated again at the next charge cycle. This helps to prevent bromine from reaching the positive electrode, where it would react with the zinc, causing the battery to self-discharge. Ions can move quicker, decreasing charging time. It is a widely available, relatively inexpensive metal, which is electropositive, with a standard reduction potential E° = −0.76 V vs SHE.

The ZBM2 zinc-bromine flow battery is designed to work on its own and can also scale to work as part of a much larger energy storage system, with as many batteries as you require. “Then we have big plans to add Gelion storage to our rooftop solar structures, so we feel very lucky to have early access to this really breakthrough technology.”. Sydney-based energy storage start-up Gelion has officially launched onto Australia’s booming battery market, with a new take on zinc bromine chemistry it says can offer a cheaper, safer and more sustainable alternative to lithium-ion. 39.1–39.8 (2002), This page was last edited on 21 November 2020, at 03:28. This creates the possibilities for new housing developments to be completely powered by solar systems that are off the grid. It’s Endure batteries can be scaled up from the core cell size – which at the moment is 5Wh – to 7-25kWh for residential; 50-100kWh for commercial; and containerised at 1MWh for grid-scale applications. In a video on the company’s website, Gelion says it has partnered with construction companies to test the batteries inside the structure of their buildings, “so the walls can become batteries.”. The company currently has an automated production facility it’s “working with” in Australia, and a semi-automated plant in India, about which Fitzpatrick says there will be “more to talk about” in coming weeks. “In addition, we are able to run at reasonably high temperatures, have no need for active cooling, and the batteries are able to discharge to zero per cent and be safely stored and transported, (unlike) others, which have to be kept in a partially charged state.”. The big difference with Gelion Endure is that it’s a non-flow battery that uses, as the name suggests, a gel approach.
