Engineering:Single liquid flow battery
Single liquid flow battery (SLIQ) is a liquid battery which consist of only one rechargeable liquid and a technology which can be used for grid storage. This is an interesting concept due to the simplicity, low cost, durability, thermal stability (no thermal runaway), low carbon foot print, eliminating the need of rare earth minerals for storage and its applicability to transportation systems. Departments of Business Energy And Industrial Strategy of UK (BEIS) has identified a company which has successfully installed such a prototype in year 2013. According to the BEIS Report this is a novel flow battery technology that is low-cost, long lasting and easily scalable. The result is a polysulfide redox Single Liquid Flow Battery (SLIQ). According to this report[1] this technology has the potential to make a significant cost reduction to both the capital and levelized cost of energy storage. In addition to low cost, the SLIQ has high energy density, millisecond response time and +20 year lifetime. The power and energy are independently scalable giving complete flexibility and high efficiency (92%) has been demonstrated by the first demonstrator installed at Inverie on the Knoydart peninsula in Scotland, UK. A detailed report of the first prototype of this groundbreaking technology can be found in this case study.[2] Technologies such as the SLIQ are crucial to fight the present climate crisis. Inventors have shared audio and visual material online for interested parties to understand the technology and to use it with renewable energy technologies[3]
Invention and Inventor
The Single Liquid Flow battery or the SLIQ technology was invented in year 2013 by Pasidu Pallawela. According to World Intellectual property organisation WIPO Pasidu Pallawela and Power Migration Partners Ltd holds patent rights to this technology. Patent information is shown here - Pasidu Pallawela's Single Liquid Flow Battery Technology Further information about this patent is found in the UK intellectual Property office website. Single liquid flow battery patent[4] Pasidu Pallawela is credited with multiple inventions and granted patents over the past years such as surface area-based pressure sensing device [5] to life saving energy back packs.[6] Pasidu Pallawela has delivered talks about this novel energy storage technology in several high-profile industrial energy conferences such as All Energy conference and exhibition in the UK.[7] As a business innovation, this was nominated for MEL British Chamber of commerce Awards[8] in 2017 as the best business innovation and won the category award[9]
Prototypes and industry application
According to Sustainable Islands International website report[10] a 30kWh/8kW prototype has been installed in Scotland to support a remote community and has been running successfully since 2013.
The company has been recently selected by Canadian and UK governments to install large scale SLIQ battery systems to support the grid and to support storage of renewable generation.[11] According to this news article in a British news paper says that this technology and supporting electronics will demonstrate how this energy storage systems can increase uptake of renewables, save money for customers and utilities, and accelerate carbon reductions by boosting the use of electric energy.
