VESS develops vanadium redox flow battery systems for marine applications, designed to meet the growing demands for decarbonization, safety, and long-term operation in shipping. Our solutions are suitable for both new ships and electrification and e-retrofit of existing vessels.
The marine environment requires energy systems with high safety, long life, and minimal maintenance. Vanadium flow batteries offer several advantages over other technologies.
The system achieves a service life comparable to, and in some cases longer than, the hull of a ship.
The water-based electrolyte and intrinsically safe chemistry eliminate 100% of the risk of overheating and fire.
VESS vanadium batteries do not need to be replaced every 5-8 years, like lithium batteries.
The system guarantees a low cost per 1 kWh of energy, considering all costs throughout its life.
The systems adapt to the specific ship through flexible configurations of stacks, electrolyte tanks, and pumping modules.
VESS is implementing a recharging technology by replacing the electrolyte. Similar to traditional fuel bunkering, the low-charge electrolyte is drained from the ship and replaced with a charged one. The process is carried out via a two-way pumping system for about 20-30 minutes, after which the vessel can continue its route with full energy capacity. The technology is applicable to:
VESS plans to build a stationary vanadium redox flow battery (VRFB) station with a service center in the Black Sea, which will allow all vessels that:
VESS systems create a closed, sustainable, secure, and seamless cycle of products and services that enable you to focus on the processes that create real value for you.
Electrolyte recharging barges function as floating power stations and are a key element of the VESS marine ecosystem. They consist of the following components:
