Electric cargo ships crossing oceans could be just 3 years away. CATL's marine division has already supplied batteries for 900 vessels and is making big strides with sodium-ion tech.
Falling battery prices are finally making long-range electric shipping economically viable—a huge step toward zero-carbon ocean freight.

CATL Expects Oceanic Electric Ships in 3 Years - CleanTechnica
Support CleanTechnica's work through a Substack subscription or on Stripe. News in batteries and electrification has been coming fast and furious lately. Recently, Su Yi, the head of CATL’s marine division, stated, “CATL’s marine business already covers inland rivers, lakes, and coastal waters, and is now advancing toward ocean-going applications.” ...

Maritime Communication in Evaporation Duct Environment with Ship Trajectory Optimization
In maritime wireless networks, the evaporation duct effect has been known as a preferable condition for long-range transmissions. However, how to effectively utilize the duct effect for efficient communication design is still open for investigation. In this paper, we consider a typical scenario of ship-to-shore data transmission, where a ship collects data from multiple oceanographic buoys, sails from one to another, and transmits the collected data back to a terrestrial base station during its…

Accurate and Effective Model for Coexistence of Classical and Quantum Signals In Optical Fibers
The rising interest in quantum-level communication has resulted in proposals for coexistence schemes with classical signals within the same fiber optic channel, where the most recent proposals leverage novel fibers designed for space-division multiplexing (SDM) transmission. In all cases the large power difference between classical and quantum channels presents challenges for such schemes, as the classical signals generate interfering noise that corrupts the quantum signal. In this work, we dis…
