Redflow Limited, a publicly-listed Australian company (ASX: RFX), produces small 10kWh zinc-bromine flow batteries that tolerate daily hard work in harsh conditions. Marketed as ZCell and ZBM2, Redflow batteries are designed for high cycle-rate, long time-base stationary energy storage applications in the residential, commercial & industrial and telecommunications sectors, and are scalable from a single battery installation through to grid-scale deployments. Redflow batteries are sold, installed and maintained by an international network of energy system integrators. Redflow’s smart, self-protecting batteries offer unique advantages including secure remote management, 100 per cent daily depth of discharge, tolerance of high ambient temperatures, a simple recycling path, no propensity for thermal runaway and sustained energy delivery throughout their operating life.

Australian energy storage technology company Redflow Limited (ASX: RFX) is pleased to announce that it has signed a collaboration agreement with Chinese zinc-bromine flow battery company ZbestPower Co., Ltd, to supply a large scale (100kwh) Redflow battery energy storage solution for a demonstration project for a key smart grid project in China.

The Redflow deployment will be part of the Haidong Transportation Group’s Smart Grid Project in Qinghai Province, which is recognised as a key market in China’s shift to a low carbon renewable energy future. Sponsored by the China National Energy Bureau, this Smart Grid Project consists of a 66KW solar PV parking carport, 18 EV fast charging points, 1MWH energy storage system and smart energy management system. The energy storage system will allow the Haidong Transportation Group to charge its electric vehicles with renewable energy and energy at the lowest price from the grid, and analyse various energy storage technologies. ZbestPower is managing the entire project.

Under the Collaboration Agreement, Redflow and ZbestPower have agreed to develop a large scale battery storage solution to meet critical project milestones set by Haidong Transportation Group, demonstrate the technical and economic viability of the Redflow system over the duration of the demonstration and collaborate on leveraging the Redflow system for commercial opportunities in China.

In a project backed by the Thai Government, the village of Ban Pha Dan in Lamphun province is using solar cells to harvest energy and a high-performance hybrid battery system, including ZBM2s, to store energy for a village microgrid that is separated from the national electricity distribution network.

Ban Pha Dan, 70km south of the northern Thai city of Chiang Mai, is a small village that has lacked access to electricity because it is surrounded by a wildlife reserve where power poles are forbidden. This microgrid project was initiated by Thailand’s Energy Ministry and the Renewable Energy for Sustainable Association with financial support from the Energy Conservation Promotion Fund.

Thailand’s Energy Minister Dr Siri Jirapongphan visited Ban Pha Dan to inspect the new microgrid and energy storage system in mid-January. Later that month, the Thailand National Energy Policy Council, chaired by Prime Minister Prayut Chan-o-cha, approved Thailand’s Power Development Plan, which prioritises the development of renewable energy sources for the period 2018-2037. Dr Jirapongphan said that non-fossil energy would account for 35 per cent of total capacity by 2037. 

Australian energy storage company Redflow Limited (ASX: RFX) has won a follow-up sale of 32 zinc-bromine flow batteries to provide standby energy storage for mobile phone towers in South Africa.

This second sale follows an initial order last month for five batteries for use at mobile phone towers run by a leading South African telecommunication company. The towers are owned by a local company that is supported by the South African Government’s Black Economic Empowerment (BEE) affirmative action agenda.

Redflow CEO Tim Harris, who received the new order after a visit to South Africa last week, said it clearly demonstrated the technological and commercial viability of Redflow’s zinc-bromine flow batteries for telecommunication deployments. “Our batteries thrive on heat and hard work, which is what these sites in South Africa require.  Following yesterday’s Optus announcement, today’s new sale further highlights the value proposition that Redflow’s ZBM2 zinc-bromine flow batteries deliver to telecommunications companies, both in Australia and overseas,” he said.
