Big benefits of shore-side electricity

Shore-side electricity can drastically reduce the emissions from fossil-fuel-powered auxiliary engines of ships at berth, according to a new study that has estimated the auxiliary power demand at berth for 714 major ports in the European Economic Area and the UK.

The level of emission reductions depends on whether the auxiliary power demand at berth would be supplied from national grids or from green (CO₂-neutral) electricity. The former could reduce annual CO₂ emissions by 3 Mt, and the latter by 5 Mt. This equals an average reduction of overall shipping emissions by 2.2 (3.7) per cent and requires only 0.2 per cent (6.4 TWh) of the current electricity generation capacity of the EEA and the UK. Using shore-side electricity from the grid can also contribute to substantial annual local air pollution reductions of 86,400 tonnes of NOx, 4,100 t SOx, 1,600 t PM10, 4,300 t CO, 94 t CH₄, 4,800 t NMVOC, and 235 t N₂O.
