Redox flow battery engineering & technology
NovaFlow develops technologies designed to reduce the cost and resource dependency of redox flow batteries. Today, we support research and industry partners with specialized engineering for cells, stacks, laboratory test systems and complete RFB subsystems.
01 / 05 What we do
Specialized engineering for RFB cells, stacks, laboratory test systems and complete subsystems. NovaFlow delivers documented, ready-to-run solutions tailored to the requirements of universities, research institutes and industrial partners.
NovaFlow is developing PEPS for decentralized production and recycling of vanadium electrolyte, alongside advanced bipolar plates for industrial RFB stacks. PEPS is designed to reduce dependence on high-purity raw materials, lower electrolyte costs and potentially reduce transport-related CO₂ emissions by up to 85% through on-site production.
02 / 05 Engineering services
NovaFlow supports universities, research institutes, technology developers and industrial companies in the design and validation of RFB cells, stacks, test systems and subsystems. Our strongest experience is in vanadium redox flow batteries, with relevant engineering principles transferable to other RFB chemistries.
Design and development of customized laboratory and pilot test systems for RFB cells, stacks, components and electrolyte studies.
Mechanical and electrochemical engineering support from laboratory cells to stack concepts.
Development support for complete RFB subsystems, research prototypes and pilot installations.
Structured planning and evaluation of RFB development work.
Contact NovaFlow to discuss scope, interfaces and technical requirements.
For investors
NovaFlow is raising a pre-seed round to validate its electrolyte production process, establish laboratory proof for PEPS and bipolar plates, prepare the initial patent filing and advance three signed non-binding LOIs toward pilot projects.
03 / 05 Technology in development
NovaFlow is developing a portfolio of technologies that targets major cost drivers in vanadium redox flow batteries. The current priority is the validation and protection of PEPS and its underlying electrolyte production and recycling process.
PEPS is NovaFlow's development platform for decentralized production and recycling of vanadium electrolyte. The platform is intended to operate at or near the battery project site, reduce transport requirements and allow the use of a broader range of vanadium containing feedstocks.
NovaFlow has developed a process intended to convert suitable vanadium-containing secondary materials and waste streams into battery-grade electrolyte. The process could reduce dependence on high-purity raw materials, lower electrolyte costs by up to 50% and reduce transport-related CO₂ emissions by up to 85%.

04 / 05 Why redox flow batteries
Redox flow batteries combine non flammable aqueous electrolytes, independent scaling of power and energy, long operational life and the potential for circular electrolyte use. NovaFlow is working on the cost and supply chain barriers that currently limit broader deployment.
