Dutch farm deploys six Redflow batteries

In a Netherlands first, a Dutch dairy farm has deployed six Redflow ZBM2 zinc-bromine flow batteries to store self-produced solar energy that can support its milk production with sun-harvested energy. Dubbed the Photon Farmer, the project aims to store solar energy for the farm’s use with six 10 kilowatt hour (kWh) ZBM2 batteries, the first Redflow deployment in the Netherlands.

Located at Vierakker in the eastern Netherlands, the 57.5-hectare family-owned farm currently stocks 110 dairy cows. Due to public importance, the European Union is co-financing the deployment, which could revolutionise energy supply by supporting businesses to become energy independent.

ICL, a leading global producer of bromine and supplier of the advanced zinc-bromide electrolyte used in ZBM2 batteries, proposed Redflow for the Photon Farmer project because of the ground-breaking advantages of zinc-bromine flow batteries over older battery types such as lithium and lead-acid.

Redflow Global Sales Director Andrew Kempster, who is visiting the Netherlands this week for the project’s launch, said the Photon Farmer had produced energy with solar panels for several years. “The battery project is seeking the best business model for future local sustainable energy production, including energy storage in a battery,” he said. “Our zinc-bromine flow battery technology is well-suited for this project.”

A prime driver for the project is to enhance the ability of farms to produce energy from renewable sources, leveraging large roofs with room for solar panels and even available space for windmills.

The Dutch energy system is based on large, central production facilities with many small users whereas renewable energy production typically occurs at distributed locations. Currently, energy is produced in line with demand, which is not possible with renewable energy. For example, a dairy farmer cannot choose to milk cows only when the sun shines or when the wind blows.

Batteries solve this problem by storing surplus renewable energy. The Photon Farmer project aims to learn if the ZBM2, with its intelligent battery management system, can optimally match supply and demand. The Redflow ZBM2 is the world’s smallest flow battery.

Redflow’s unique battery is intrinsically fire safe, due to its design and the fact that its bromine electrolyte is inherently non-flammable. The ZBM2 delivers superior energy storage performance, being capable of 100 per cent daily Depth of Discharge and delivers 10 kWh of sustained storage for its warranted 10 years. This means no loss of energy storage capacity over time, as occurs with other battery chemistries such as lithium and lead-acid.

The Redflow ZBM2 battery is sold and installed globally for use in small to large-scale telecommunications, industrial and commercial applications. ZBM2 batteries are already in use in Austria, Germany, Portugal and Spain.

Redflow has also launched its ZCell residential energy storage system for homes in Australia.

The ZBM2 zinc-bromine flow battery is made from components that are easily recyclable or reusable, which makes it a sustainable battery solution. Due to this unique design, the ZBM2 was nominated for the Responsible Care Award in 2016 by the VNCI – an annual sustainability prize within the Dutch chemical industry.

Off-grid suburb a ‘perfect storm’ for energy giants

Australian energy companies are facing a “perfect storm” as renewable alternatives are hastening the move to off-grid electricity. Earlier this month US energy giant Brookfield announced it had signed a deal with property group LWP to build a new suburb near Newcastle, NSW, powered entirely off-grid, challenging incumbent industries to adapt or perish. The move has enormous implications for rural and regional communities throughout Australia where the tyranny of distance has often led to towns becoming stranded at the far end of a very long energy line. Simon Hackett, chair of RedFlow —an Australian company that designs off-grid batteries — told Fairfax the Australian energy industry is facing a “perfect storm”. “The combination of high energy prices, widespread deployment of photovoltaic solar panels (PV), a ready supply of sunshine and the looming presence of widespread, affordable and effective energy storage systems is encouraging customers to look for other ways to supply their energy needs,” he said. Read the full story at the Sydney Morning Herald

Redflow welcomes Tesla to the battery market, as investors including Graeme Wood and Simon Hackett pour in another $16 million

Redflow has welcomed the entry of US electric car maker Tesla to the large-scale battery market, after investors poured an additional $16.1 million into the zinc-bromide module (ZBM) maker. The startup raised approximately $9.7million, along with a $6.4 million entitlement offer. The entitlement offer allowed existing shareholders to purchase one new share for every seven they already owned reports. Read more at SmartCompany
