Accelerator selected the maker of an organic flow battery among a group of “startups with the potential to dramatically alter the future global energy landscape”.

Australian stock exchange-listed flow battery manufacturer Redflow has scored a second order for its devices from the Rural Connectivity Group, a New Zealand-based telecommunications company.

There exist opportunities for flow batteries to target areas of the market lithium-ion “can’t provide in an economically justifiable way,” the chief commercial officer of Invinity Energy Systems has said.

Realising the theoretical promise of solar-wind-storage hybrids is far from straightforward, with individual projects likely to vary considerably. Ben Willis examines some of the technical complexities of combining different technologies into a single, profitable entity.

“The bottom line is that this is a good business decision. We will get back our money in eight to 10 years at the current price of power. As the price of energy goes up, we’ll pay it back even quicker.”

Avalon Battery and redT have revealed that their proposed merger will create a new company to be known as Invinity Energy Systems.

redT has been given a provision notice from Pivot Power to manufacture 2MW/5MWh of vanadium redox flow batteries as part of the Energy Superhub Oxford project, striking up a partnership with vanadium producer Bushveld Minerals to support the project.

Former Governor of New York George Pataki has welcomed the possible siting and construction of a vanadium redox flow battery (VRB) factory in the state.

As energy storage becomes an increasingly integral part of a renewables-based system, interest in and discussion around non-lithium (and non-pumped hydro) technologies increases. A team of experts from CENELEST, a joint research venture between the Fraunhofer Institute for Chemical Technologies and the University of New South Wales take a deep dive into redox flow batteries.

While lithium-ion batteries get most of the headlines, long-duration solutions of various types are gaining ground. Alice Grundy and Andy Colthorpe profile some of the established and emerging concepts in this increasingly important field.
