DEWA doubles down on storage with patent for redox flow battery stack
Dubai Electricity and Water Authority’s Research and Development Centre (DEWA’s R&D Centre) has filed a new patent for a redox flow battery stack with improved electrolyte distribution.
The battery stack is stated to have a streamlined shape by changing the size of the cell at the inlet and outlet sections. According to the R&D Centre, this ensures a reduced pressure drop, better performance and efficiency of the battery flow system leading to increased power density, and reduced manufacturing costs.
The new patent, which is the fourth filed by the Centre, reportedly resolves a significant challenge in flow battery.
Conventional redox flow battery stack has inactive sites at the edges of the cell which restrict mass transport of the reactants at the electrode/electrolyte surface, leading to pressure drops which affect the overall efficiency and performance of a flow battery system.
HE Saeed Mohammed Al Tayer, MD & CEO of DEWA, expressed his pride in the scientific achievement, adding that it aligns with DEWA’s strategy to energy security by adopting the latest technologies and implementing several energy storage projects.#

“The patents registered by DEWA reflect our commitment to contribute to the localisation of knowledge and the participation of the scientific community in specialised scientific research, which aims to develop the clean and renewable energy sector.”
This news comes in as DEWA implements numerous energy storage projects.
These include using concentrated solar power (CSP) in the 4th phase of the Mohammed bin Rashid Al Maktoum Solar Park, which combines CSP and photovoltaic solar panels with a production capacity of 950MW.
DEWA is also implementing a 250MW pumped-storage hydroelectric power station in Hatta as well as a pilot project for energy storage at the Mohammed bin Rashid Al Maktoum Solar Park, using Tesla’s lithium-ion battery solution.
