Redflow, the flow battery manufacturer, settles in after a turbulent year

On 30 August Redflow, the Brisbane-based manufacturer of Zinc-Bromine flow batteries, announced that its revenue for the year to 30 June 2018 was Australian$1.8 million (£1m) for a loss of A$12m. Corresponding results for the previous year were A$1.4m and A$12.9m. Redflow describe 2017/18 as a turnaround year: it was certainly turbulent, with the manufacturing [...]

Some Good News for Flow Batteries

Two recent news items show that flow batteries are starting to receive more attention. In the first, RedT announced the sale of two systems, each with an energy storage capacity of 40MWh, to the German company Energy System Management GmbH (ESM). These are to help maintain equilibrium between supply and demand and to assure a [...]

Pumped storage could solve the storage problem if sufficient sites could be found

Pumped Storage is the method of storing electrical energy by using it to pump water from a low-level to a high-level reservoir. The energy is retrieved by reversing the process, in which the pumps become generators and the water is released back to the lower level. In the UK the best-known example is Dinorwig in [...]

Flow Batteries: a brief overview

We recently wrote about Redflow’ s involvement in grid and off-grid energy storage through the use of Zinc-Bromine batteries. This article on the exciting developments in battery technology looks at the possibilities for Flow Batteries in this area. The distinguishing feature of a flow battery is that the electrical energy is stored in a liquid [...]

Redflow raises cash to develop a more conventional market for its flow batteries

Redflow, the Brisbane-based manufacturer of Zinc-Bromine flow batteries, is in the process of raising A$14.5 million (£8.7m) on the Australian stock exchange. This follows similar exercises in 2016 and 2015 that raised A$12m and A$16m respectively. Is this money well invested? The missing link in the use of wind and solar production has been the [...]

Will hydrogen cars eliminate diesel and petrol engines from the roads

Hydrogen cars are vehicles powered by a single hydrogen fuel cell. The fuel cells work by using a “fuel stack” to use outside air with hydrogen they carry in tanks in a chemical reaction which creates electricity, with the only emission being water. I came across an early prototype of such a car about ten [...]
