As the world scales up on secure, clean and affordable energy generated from renewables, there is an increasing requirement for large-scale energy storage systems that are able to efficiently store and release power when required. TFP is at the forefront of this transformation, providing advanced materials that enhance the performance and sustainability of flow batteries.  

TFP has a range of innovative solutions for flow battery chemistries that are charging ahead within energy storage markets, helping to power a cleaner, greener future.  

What is a Flow Battery?

Flow batteries are recognised as one of the most promising technologies capable of storing renewable energy on a large scale, offering a broad range of benefits that make them a valuable asset in the energy transition.  


Flow batteries typically last for up to 12 hours, significantly longer than the 4 hours achieved by Lithium-Ion systems. They offer the capability of flexible, large scale energy storage, while maintaining a consistent supply of renewable energy. This makes them well suited to electrical power grids and attractive for users requiring uninterrupted supply or back up power such as hospitals, manufacturers and offices. 


The long-duration storage of flow batteries allows renewable energy to be stored and distributed when needed, supporting a a future of 100% green energy. 


Unlike lithium-ion batteries, where cell size restricts the charge capacity, flow batteries can be engineered with larger storage tanks enabling the use more electrolytes to meet energy requirements. This flexibility enables a de-coupling of power and energy, creating robust battery systems. 


Flow batteries can be constructed from low-cost, readily available materials and recyclable materials, such as thermoplastics and carbon-based materials. The electrolytes can be recovered and reused, offering a cleaner alternative to lithium-ion batteries, which are harder to recycle. 

Flow batteries have the potential to deliver the full benefit of renewable energy and ultimately, achieve commitments of Net Zero Goals. 

What makes flow batteries unique? 

Unlike traditional batteries, flow batteries store energy in liquid or gaseous reactants housed in separate tanks from the cell where the reaction occurs. This design offers flexibility and scalability. There are several types of flow batteries, including Vanadium, Zinc-Bromine and Hydrogen-Bromine, each with different reactants.  

TFP’S Advanced Solutions for Flow Batteries 

TFP regularly collaborates with battery manufacturers to advance power and energy device technology. Our nonwovens, are used in many battery chemistries including flow batteries, lithium –ion, sodium nickel chloride and lead-acid.  We specialise in providing high performance materials that enhance the efficiency and durability of flow batteries. Our solutions include:  


Our nonwovens, featuring carbon fibre networks, offer high C-rate capability when coated, and are produced using proprietary wet-laid technology to ensure high surface area and porosity.


TFP Catalyst range features highly tuned molecular ratios and electrochemical active surface area (ECSA), to produce a catalyst demonstrating excellent durability without hindering the catalytic performance.


Our chemically resistant glass products, such as E, C, and ECR glass, are specifically engineered to meet the rigorous demands of lead-acid and lithium thionyl chloride battery systems.

To learn more about our innovative battery technology solutions, join us at the next edition of the International Flow Battery Forum 25/27 June in Glasgow, Scotland, where Dr. Srijita Nundy, TFP Hydrogen’s Head of Innovation, will present a poster on ‘Material Advancements in Flow Battery Technology’.
