Solar battery breakthrough

Battery storage has long been the major cost of home, business and even caravan solar. Most new systems are now lithium-ion and costs about $1 per watt/hour (most home systems need 12,000-15,000 watt/hours).

This may well be slashed by a new Australian-developed battery (called Gelion) that uses zinc-bromide: a (claimed) much cheaper and safer technology than the lithium-ion batteries used now.

The zinc-bromide chemistry used by Gelion operates without the need for active cooling and enables 100% of the battery’s capacity to be used (most batteries are damaged or wrecked by that).

The Gelion company is based on work by Professor Thomas Maschmeyer, winner of the 2018 Eureka Prize for Leadership in Innovation and Science. The so called the Gelion Endure system is inexpensive, robust, safe, fully recyclable and scalable.

The company plans to launch the system into the $70 billion global energy storage market. It states that ‘the global battery market is currently valued at $60 billion to $70 billion and yet, if we were to take all current batteries produced in one year, they would only have the capability to store around The zinc-bromide chemistry used by Gelion operates without the need for active cooling and uses 100% of the battery’s capacity, the company says

 Its electrode surfaces can be rejuvenated remotely using battery management systems, making it suitable for stationary energy storage applications in remote sites.
