Green revolution on water
As land NEVs surge, the water's green revolution quietly speeds up. The Yangtze pure-electric container ships 'Green-Water 01/02' run the Nanjing–Nantong–Yangshan route with 24 box-type battery packs via 'swap-not-charge', zero-emission, zero-pollution, zero-noise—Tonghai terminal built charge-swap stations for clean-energy ships, 'as flexible as swapping a phone battery'. The other berth-emission lever is shore power: docked ships plug into shore electricity and shut diesel generators, cutting smoke and noise at source.
From built to used
Shore power moves from 'built' to 'used'. Nantong Tonghai port's shore-power coverage and usage both hit 100%, H1 2026 serving 1,410 ships with 178.2 MWh; Hubei built 108 shore-power berths, 307 units, and by Feb 2026 had served 84.5k+ ships, replacing 17.2k t diesel and cutting ~44.6k t pollutants. Tianjin Port's C-zone smart terminal is the world's first 'smart-zero-carbon' terminal, 100% self-generated green power, ~95k tCO₂ cut yearly; national key-port berths >90% shore-power coverage, ~90 GWh national use in first 8 months of 2025. Guangdong built 1,285 shore-power facilities covering 1,674 berths (93.9%).
Yantai's close sample
For a port city like Yantai, shore power and electric ships are a 'close-at-hand green sample'. Dongdian Huichong's community and public charging sees Yantai Port's docked ships, port machinery and logistics vehicles electrifying, naturally same-source as the city charging network—operators should watch port, anchorage and ship-power-bank storage refill extension. Shore power lights ports, green power feeds ships; rivers and seas clear, waterfront residents benefit first. Land and water both green make the complete green-travel map.
