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.

Targeting a national economic goal in mind of making hydrogen competitive with natural gas, Australia’s government has put AU$70 million (US$44.3 million) into a “deployment funding round” for renewable hydrogen.

“The elimination of solar energy’s intermittency and ensuring its 24-hour availability at grid-competitive cost is the holy grail and RayGen has found it”.

An optimal power system portfolio for the US state of California that would drive the world’s fifth largest economy towards greenhouse gas reduction goals for 2030 and then to zero carbon by 2040, includes 1GW of long duration energy storage.

When lithium-ion’s dominance of the energy storage market begins to wane, redox flow batteries are well positioned as a strong competitor, emerging technology market research and business intelligence group IDTechEx has said.

Zinc8 Energy Solutions is to deploy a 100kW / 1.5MWh zinc-air battery energy storage system in New York City, with financial support to come from New York State Energy Research and Development Authority (NYSERDA).

Enabling longer duration storage and non lithium-ion technology, what to do with the storage capabilities of electric vehicles and how the industry is overcoming regulatory hurdles were all key topics discussed at this year’s Energy Storage Summit in London.

The UK energy storage is currently “in limbo” despite improvements to regulation made in recent years, according to panellists at the Energy Storage Summit.

Battery storage in continental Europe “is not working anymore” following the integration of the European market, according to Next Kraftwerke CEO Jochen Schwill.
