Tesvolt Ocean, a new joint venture 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.
TESVOLT OCEAN is a joint venture between the two maritime industry experts, TESVOLT Maritime Solutions from Germany and Ocean Batteries from Norway. TESVOLT holds a 51% stake in the joint venture TESVOLT OCEAN.
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 in the ship – even on the floor. Due to its disruptive technology, the new power storage solution also features the highest energy density, the lightest weight, and the fastest charging capability on the market. This makes clean e-drives for shipping easier to implement as well as more cost-efficient.
TESVOLT Maritime Solutions has supplied battery storage systems since 2018, primarily for workboats, deep-sea applications, and aquaculture, but also for pleasure craft and the yachting industry. TESVOLT Maritime Solutions has already equipped 160 ships with environmentally friendly battery propulsion systems, including the award-winning “E-Spatz,” a working vessel of the German Federal Waterways and Shipping Administration. Ocean Batteries has been offering modular, safe, and powerful battery solutions since 2019. TESVOLT OCEAN presented its new “Kaptein” battery storage system at SMM, the world’s leading maritime industry trade fair, last week in Hamburg.
“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,” explained Kent Thoresen, CTO of TESVOLT OCEAN. “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.”
Most batteries approved for use in shipping did not even have a continuous C-rate of 2 C. At 4 C, the “Kaptein” storage system offers the highest continuous C-rate available in the maritime industry to date. This means significantly shorter charging times for ship owners.
The new storage system also scores highly in terms of weight. At just 4.83 kg per kWh of storage capacity, it will be the lightest battery system for shipping on the market; batteries currently available on the market weigh at least 7 kg per kWh. A unique fire suppression system ensures maximum safety.
“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,” added Kilian Hoffmann, CCO at TESVOLT OCEAN. “We’ve already had a huge number of inquiries about the new battery system.”
Based in Lübeck, Germany, the company develops high-performance battery storage solutions that are specially designed for the demanding conditions at sea. With its innovative products and solid services, TESVOLT OCEAN is setting new standards in Europe’s maritime energy supply.
