Tesvolt Ocean rolls out ‘Kaptein’ power storage solution

Tesvolt Ocean, a brand-new joint venture (JV) based in Lübeck, Germany, has developed a battery system that will enable significantly more ships in the maritime and inland shipping sector to be equipped with clean e-drives for the first time.

The JV was recently formed by German energy storage solutions provider Tesvolt’s Maritime Solutions division (51%) and Norway’s marine battery specialist Ocean Batteries (49%).

Space in ships was often too tight for the compact battery storage systems available on the market, until now. The new “Kaptein Series” power storage system has the advantage that the battery modules can be installed individually anywhere aboard the ship – even on the floor, the JV said.

As explained, the new power storage solution also features high energy density, light weight, and fast charging capability. This makes clean e-drives for shipping easier to implement as well as more cost-efficient.

Tesvolt Ocean presented its new battery storage system at the maritime trade fair SMM in Hamburg last week.

“We’re entering the market with a best-in-class storage system, offering a technological solution for the biggest pain points of ship owners, system integrators, and shipyards,” Kent Thoresen, CTO of Tesvolt Ocean, commented.

“The range of ships with electric propulsion, for instance, is still a problem for many owners. Ship spaces are often cramped, so not enough battery modules can be accommodated to achieve the desired range. At 246 Wh per liter, our new Kaptein system has the highest energy density on the market to date, meaning despite its high capacity it takes up very little space.”

“We spent three years speaking intensively with customers in six focus groups about what they need. That’s why Kaptein fits their needs so well. It solves real problems in e-propulsion for ships,” Kilian Hoffmann, CCO at Tesvolt Ocean, added.
