Port Electrification
Definition
Port electrification is the replacement of fossil-fuel-powered equipment and energy use in ports with electricity, encompassing shore power (or cold ironing) that lets berthed ships switch off auxiliary engines, plus electrification of cranes, yard vehicles and harbour craft. Shore-side electricity can virtually eliminate a ship's at-berth emissions where the grid is clean.

Overview
How it is used
Regulation is accelerating adoption: the EU's FuelEU Maritime requires container and passenger ships to use onshore power supply at major EU ports from 2030, and California's at-berth rules have long mandated emissions control.
Why it matters
Ports are concentrated nodes of maritime emissions and urban air pollution; electrifying them delivers immediate local health benefits while building the infrastructure shipping's broader decarbonisation will need.
