A port has said it remains “on course” to be the first in the UK to introduce shore power for cruise ships.
Associated British Ports (ABP) said it would meet a previous pledge to install the technology in Southampton in 2020.
However the firm said it had not yet resolved issues over funding and a potential drain on the National Grid.
On a recent visit to the port, prime minister Boris Johnson said he was “very interested” in shore power as a means of limiting pollution from ships.
Shore power, otherwise known as “cold ironing”, reduces the time vessels run their engines in port.
Shipping is forecast to emit between 2% and 6% of nitrogen dioxide emissions in Southampton, ABP’s Port Air Quality Strategy said in 2018.
However a report to Southampton councillors in January 2019 said shore power “demonstrated no discernible benefit to nitrogen dioxide concentrations at EU relevant locations”.
The report added that shore power could nevertheless deliver unspecified “public health benefits”.
The council applied in January 2019 for a government grant to fund a £7m shore power scheme.
However the bid was rejected because of concerns over insufficient benefits and speed of delivery, the authority said.
On a visit to Southampton on 2 December, the prime minister told reporters: “We need to reduce the diesel fuel emissions from ships.
“One thing you could do… which I’m very interested in doing… is support the port in providing the juice from the shore, plug them in.” . . . . . . .
