Spain has developed a new organic redox flow battery

Recently, CIC EnergiGUNE, a research center for energy storage technology in Spain, led the research and development of a high-performance green redox flow battery (Higreew) research project to produce cheap and efficient redox organic flow batteries.

It is reported that the project is funded by the European Commission with 3.8 million euros, including scientists from European universities such as the Autonomous University of Madrid and the University of Bohemia, as well as Czech redox battery expert Pinflow and electrochemistry Equipment supplier C-Tech, etc.

This new battery will be based on a water-soluble organic electrolyte. Scientists say that the battery electrolyte has low cost and is compatible with optimized low-resistance membranes and fast electrode dynamics. This new technology will enable researchers to develop more environmentally friendly and sustainable redox flow batteries with higher power and energy density, while providing longer life.

According to concerns, the researchers ’goal is to control energy storage costs below 0.10 euros / kWh / cycle before the end of the 40-month project that started last month; / kWh / cycle or less.

Later in the study, the batteries will be tested at the Spanish Gamesa plant. Scientists say the project aims to prove that organic flow batteries can become a sustainable alternative to vanadium batteries. Vanadium batteries are one of the key raw materials listed by the European Commission.

In addition, unlike vanadium redox flow batteries, such devices are more environmentally friendly because they do not contain heavy metals or harmful acids.
