The working paper “Electrifying ports to reduce diesel
pollution from ships and trucks and benefit public health: Case studies of the
Port of Seattle and the Port of New York and New Jersey” from the International
Council on Clean Transportation (ICCT) looks at the potential impacts on air
quality and public health of full electrification of the ports.
Both the port of Seattle and Port of New York and New
Jersey have electrification plans underway, but the study forecasts the impact
of full electrification – 100% shore
power for ocean going vessels at berth, 100% electrification of harbour craft,
and 100% electrification of trucks in the port.
Using computer models to estimate the impact of such
measures, authors Zhihang Meng and Bryan Comer, Ph.D. found that average
concentrations of fine particulate matter near the Port of Seattle could be cut
by 0.3–0.42 μg/cu m, compared to a 2019 average of 7.5 μg/cu m. The area
effected by emissions from the Port of Seattle could also be cut from from
292.1 sq km to 54.5 sq km.
“Air quality
improvement near the Port of Seattle under the full electrification scenario is
estimated to provide monetized health benefits of over $27 million annually.
For the Port of NY/NJ, air quality improvement is expected to translate to at
least $150 million of health benefits per year,” said the paper.
The total area affected by Port of NY/NJ emissions
could be cut from 2,172.3 sq km to 504.5 sq km, with significant improvements
in air quality in both the City of Elizabeth and Jersey City. Oceangoing
vessels were found to be the biggest contributors to emissions of carbon
dioxide, particulate matter and nitrogen oxides. Full electrification could reduce port fine particulate emissions by
75% at the Port of Seattle and 69% for NY/NJ, said the report.
