PRESS RELEASE: Lutherstadt Wittenberg/Germany, 10.9.2024 – TESVOLT, a market and innovation leader for commercial and industrial energy storage solutions in Germany and Europe, has announced a new joint venture, TESVOLT OCEAN. The TESVOLT Maritime Solutions division merged with Ocean Batteries from Norway last week. The innovation and market leader TESVOLT is focused on commercial and industrial energy storage solutions in Germany and Europe. Its 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. 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.
