Application areas for redox flow batteries
Storage of green electricity for increasing self-consumption
It is becoming ever more important to store green electricity, especially in PV systems. Operators of PV systems are being confronted with an economic dilemma: they receive, for example, just 7 cents per kilowatt hour (kWh) for the electricity they feed into the grid, while they have to pay, say, 30 cents per kWh for the electricity they purchase. It is this difference that makes increasing your own consumption of, for example, self-generated PV electricity particularly attractive.

Installing redox flow battery storage systems means that solar power generated during the day but not immediately consumed can be temporarily stored and used when needed. This reduces the demand for expensive grid electricity and increases the profitability of the PV system - not only for private but also for commercial users!
Storage for better marketing
Optimized energy storage for the future
Redox flow batteries with our stacks or modules offer operators of large wind farms and solar plants a trailblazing storage solution that maximizes energy efficiency and optimizes the marketing of green electricity. Storing generated energy makes it possible, for example, to utilize the energy generated even during grid bottlenecks or to fully exploit the benefits of variable exchange electricity prices and sell it profitably during periods of high demand and corresponding prices.


 


Co-location: utilizing synergies and achieving added value
The strategic co-location of redox flow storage systems directly at wind or solar farms delivers a tailored and scalable solution for storing and managing energy directly on site, thereby minimizing transport losses and maximizing efficiency.
Large grid storage systems - an essential contributor to grid expansion
Scalable energy storage solutions contribute to relieving the public electricity grid by absorbing peak loads and supporting stability in the grid. Installation at grid bottleneck points in particular, coupled with a modern energy management system and intelligent control solution, increases grid stability and signifies a reduction in grid expansion.
It is possible to flexibly adapt the capacity of these systems to the specific energy requirements. Not only does this reduce costs, it also increases the stability and reliability of the energy supply.
Supply of charging points for electromobility
Fast-charging points especially require high power so that electric cars can be charged over a short period of time. High outputs often necessitate expensive grid expansion to ensure that the charging capacity of up to 350 kWh can be achieved with a 63 A connection. Connected power storage units can therefore offer a sensible and cost-effective alternative to expansion with cables and converters.
Load management (peak shaving), emergency power supply in industry
Reducing peak loads when starting up machines and systems can help to reduce grid charges. Battery storage systems can also be used to achieve an emergency power supply, i.e. the power supply is guaranteed in the event of a grid failure.
Storage systems for stand-alone grids
There is often no large-scale grid architecture for distributing electricity from large, centralized power plants in remote areas or in developing countries. This is why it often makes sense to expand stand-alone grids with renewables (wind, solar) as generators. This requires adequate electricity storage systems as a means of ensuring a constant energy supply.

			

			

				
How does a redox flow battery work?


Redox flow batteries work by storing electricity in liquids. The storage liquids, also referred to as electrolytes, are stored in two tanks. In order to charge or discharge the liquids, these are pumped through so-called stacks, where the liquids are charged or discharged by converting electrical energy into chemical energy and vice versa.
Electrons and ions are transferred between the electrolyte solutions by means of electrochemical reactions during the charging process, resulting in energy being stored in the form of chemical energy. This process is reversed during the discharging process; the electrons and ions migrate in the opposite direction and the energy previously stored is converted into electrical energy, allowing it to be utilized.
There are a number of different storage liquids. Vanadium electrolytes have been steadily developed since the 1980s and have been deployed in commercial systems for over 10 years. There are also many other promising electrolytes under development, e.g. those that are based on very affordable and widely available metals such as iron or on organic active materials that are in theory available in infinite quantities.

			

			

				
The special features of our energy storage systems in comparison to conventional batteries:

Extended service life


Redox flow: more than 15,000 charge/discharge cycles over a service life of 20 years
Li-Ion: 4,000 charge/discharge cycles on average and a service life of 10 years

More cost-effective


The long cycle life means that we can achieve a significant reduction in the costs per storage cycle, a reduction in the levelized cost of storage (LCOS). This can be 40 % of the LCOS of Li-ion batteries, depending on the system configuration!

Simple automation


Redox flow batteries offer unique flexibility in terms of adapting capacity (in kWh) and power (in kW), which can be scaled independently of each other. This makes them ideal for cost-efficient energy storage solutions with longer storage durations (Long Duration Energy Storage, LDES).

Recyclable


The design of redox flow batteries means that the active material contained in the electrolytes can be very easily separated from the system and reprocessed or recycled. This is considerably easier than with Li-ion batteries, which require complex and expensive mechanical and chemical separation processes for recycling.

No critical resources


The use of critical resources such as lithium or cobalt is no longer necessary. There are various electrolytes, many of which manage without metallic resources - making redox flow batteries a promising technology for widespread use as power storage in parallel with the expansion of renewable energies worldwide!

Non-flammable


The water-based electrolytes used are non-flammable - in contrast to lithium. This allows redox-flow batteries to be installed across several storeys and without fire distances, which means that higher energy densities can be achieved compared to lithium-ion batteries. This reduces the space requirements for larger storage systems - and therefore the costs!
The use of redox flow batteries shows its cost advantage per kWh when it comes to longer storage times. For storage times of over 6 hours, they are cheaper than lithium-ion batteries.

			

			

				

			

			

				
VANEVO products

			

						

							
Patented stacks
Bonding instead of pressing


VANEVO has devised a new manufacturing process for the core component of redox flow batteries. VANEVO stacks use fewer complex parts than existing stack concepts, simplifying the requirements. The process can also be more easily automated, significantly accelerating the assembly process.
Simple, faster and cheaper


Doing away with sealing elements eliminates the need for massive end plates for tensioning - the stacks are therefore considerably lighter and consequently easier to handle. Bonding is a cost-effective way of manufacturing VANEVO stacks and is protected by several patent applications.
> 35% less costs*
> 30% less environmental pollution*
> 5% more efficient*
40% fewer parts in our stacks*
*compared to conventional manufacturing processes and technologies.

						

						

							
Standardized modules
Modular solutions for energy efficiency


In order to simplify how our technology is used, we have developed modules that operate as efficient and user-friendly “black box” systems. These modules integrate our advanced stacks together with tanks, pipework, pumps, sensors and battery management software (BMS). They are designed in such a way that they can be easily understood and used by system integrators, much like they are used to with Li-ion modules.
Key features of our modules


Standardized 10kW power and 40kWh capacity, whereby 4 to 6 modules fit into a 20 foot container. Our modules are made up of two 5 kW VANEVO stacks and two 1000 liter tanks, rounded off with high-quality pipework, sensors, pumps and our battery management system. Easy handling is ensured by clearly defined plus and minus poles and an interface to the BMS. The modules are not only conceived for established vanadium electrolytes, they are also suitable as a platform for the widest range of electrolytes.

These modular solutions allow VANEVO customers to implement storage solutions into their existing systems in a way that is flexible, easy to integrate and cost-effective. Discover the benefits of VANEVO stacks and how they can improve the efficiency, cost and environmental performance of your energy projects.
