WHAT WE DO
Our solutions
NANOSTRUCTURED ELECTRODES
The Flow-nano solution exploits the potential of thin carbon paper and carbon cloth substrates in terms of very low hydraulic and ohmic losses, providing them with unprecedented electrochemical performance and reaction rate:
• High Voltaic Efficiency: > 80 % at 400 mW cm-2 power density
• It can sustain operation up and beyond 700 mW cm-2 power density
• Very stable and reliable performance
Flow-nano electrode not only allow operation at incredibly high power density – thus decreasing power unit costs (€/kW), but also open the possibility to a more flexible system and exploitation of the energy production, following the fluctuation of the renewable energy grid.
FLOW-NANO VANADIS SOLUTION
The Vanadís solution makes redox flow battery the most cost-effective solution for the long duration energy storage of renewables.
Our Vanadís Solution is a nanostructured flow-nano electrode, designed with a superior specific surface area and catalytic activity, that enables a threefold increase in RFB power and a much higher electrolyte utilization factor.

The Vanadís solution makes redox flow battery the most cost-effective solution for the long duration energy storage of renewables.
​
Vanadium Flow Batteries (VFBs) are one of the most recyclable types of battery available today. Vanadium doesn’t degrade. The VRFB contains a reusable electrolyte and has an infinite number of cycling capabilities, allowing the battery to last more than 20 years.
​
Unlike a conventional battery, a VRFB uses a vanadium electrolyte to store energy in separated storage tanks, not in the power cell like a conventional battery. Suitable for both grid and decentralised energy applications, the VRFB is one of the preferred energy storage technologies providing an effective solution to address the challenges of grid modernisation and stabilisation, as well as renewable energy integration.
In a vanadium redox flow battery, a vanadium based liquid electrolyte is used as the active material for storing energy. The liquid electrolyte is circulated through the electrochemical cells where reactions occur at the electrode surfaces and cause electrons to move in and out the battery.
​
The reaction rate at the electrode surface is the key operating parameter of the vanadium redox flow battery. Higher the reaction rate, more power can be extracted and more energy can be stored by the battery. This translates into lower cost per unit of power and per unit of energy.
​
Our electrodes are chemistry agnostic, therefore could be used also for redox-flow batteries based on different chemistry than vanadium.
The Flow-nano solution exploits the potential of thin carbon paper and carbon cloth substrates in terms of very low hydraulic and ohmic losses, providing them with unprecedented electrochemical performance:
• High Energy Efficiency: > 80 % at 300 mA cm-2 current density
• Large electrolyte utilization: > 70.0 % at 300 mA cm-2 current density
• Long lifetime: < 0.004% Energy Efficiency drop per cycle over long-term testing.
ENHANCED PERFORMANCE
NANOJED TECHNOLOGY
The core of our innovation is a proprietary and patented plasma-assisted nanoparticle jet deposition technology (NanoJeD), where a non-thermal plasma ionises and dissociates precursor molecules into radicals that evolve into nanoparticles of different sizes and shapes. A novel supersonic fluid dynamic approach enables to quench and collect, by ballistic impact, the spherical shaped nanoparticles onto the target substrate, increasing its specific surface area.
By tuning chemical reactions / formulations, we can enhance the catalytic activity of the nanoparticles themselves, thus further improving VRFB power density / system efficiency.
With our treatment we triple the current density compared to standard electrodes.
NanoJeD technology increases the stack power up to a factor of 3.
​
With our electrode - Vanadìs solution, we triple the current density, hence the battery power, compared to standard carbonpaper and carbon cloth electrodes.
​
This translates into:
​
- tripled output power density or
​
- cutting of unit stack cost by a factor 3
Using the proprietary and patented NanoJeD technology, defected and turbostratic carbon nano-onions are deposited onto a standard carbon paper electrode to obtain, after an annealing process, a stable configuration of nano-catalysts, strongly adhering the fibres and increasing by orders of magnitude both the active surface area and the electrochemical activity of the material.
