Nataliya Roznyatovskaya et al, have published an open acces review article on electron transfer processes for vanadium redox flow batteries. It concerns the complex reactions in diluted and concentrated vanadium electrolyte solutions.
The electrode processes play a decisive role in the efficiency and performance of vanadium redox flow batteries.

In particular, there is a little-noticed difference in the past between the properties of diluted and concentrated vanadium electrolyte solutions. For example, the results of measurements in diluted solutions cannot simply be transferred to higher and practical concentrations, since the structural properties of the vanadium species and thus also their chemical properties and reaction mechanisms are different.

Members of CENELEST are co-organising the 2020 Meeting of the International Coalition for Energy Storage and Innovation (ICESI 2020) in Sydney.

The International Coalition for Energy Storage and Innovation (ICESI) is a new international professional organization focusing on the science and technology challenges for grid scale energy and renewable energy integration.

The conference will cover three full days with a distinguished speaker, 2 plenary speakers and 42 invited speakers. The organising committee are pleased to announce that they have secured the services of the 2019 Nobel Laureate in chemistry Prof Michael Stanley Whittingham, the Founding Father of rechargeable lithium batteries, as the distinguished speaker.

ICESI is currently the only international organization that focuses on the scientific and technological challenges for the development and deployment of scalable energy storage technologies for electric grid and emerging market applications. ICESI annual conferences have a great tradition and unique style of blending fundamental research with practical applications to provide a vibrant mix of discussions on electrochemical power conversion and energy storage.

The purpose of ICESI is to establish an international forum to connect and industry in the world to address the long term scientific and technological challenges for the development and deployment of scalable energy storage technologies for electric grid and emerging market applications, and to serve as the authority, spokesperson and advocator for supporting energy storage research. In addition, ICESI will help identify the gaps in science, markets and technologies to promote collaboration in the international community and collaborations between the research community and industry, provide realistic assessment of current and future technologies, and provide guidance for long term research and long term investment. ICESI will also recognize and promote significant scientific and technological advances, individuals and teams who have made significant contributions in the field, establish new platforms and mechanisms to integrate and utilize the best resources in the scientific community and solve major scientific and technology challenges of key technologies, and speed up the transfer of these technologies to industry.

Chris and Jens together with the team Sunswift of the UNSW accompanied the preparations and the qualification for the Bridgestone World Solar Challenge in Darwin/Australia.
The World Solar Challenge is a car race in which solar-powered vehicles in different classes have to drive through the entire continent of Australia from Darwin to Adelaide. The distance is over 3000 km under the strict climatic conditions of the Australian outback.

We have published an open access article about the effect of the counter ion in the electrolyte of Vanadium Redox Flow Batteries (VRFB). Sulphate and pure chloride based electrolytes have been compared regarding its electrochemical properties in half-cells and batteries. We show here that the usage of pure chloride based electrolyts results in lower performance and a reaction of V(V) with chlorine.

Several CENELEST members took part in this year’s Smart Energy Conference and Exhibition in Sydney/Australia. In addition to presentations, numerous companies were represented as exhibitors at the two-day event. CENELEST participated as an exhibitor with its own booth. During the two days countless discussions were held and numerous new contacts from the international and national Australian sector of energy storage were established.
