The Port of Aberdeen yesterday announced a pioneering project to significantly reduce emissions from vessels on standby outside the harbour.
It is to collaborate on the venture with Stillstrom by Maersk, a new offshore-charging company.
The pair will conduct a joint feasibility study into an innovative offshore renewable-charging hub.
The concept will provide a platform for vessels to use electricity from either offshore wind or grid energy -eliminating the need for them to consume fossil fuels while idling.
It will also allow for the charging of battery packs on vessels.
The study, which will run until the end of the year, will develop a roadmap for the potential introduction of offshore-charging infrastructure at the port.
Aberdeen has one of UK's busiest harbours, with more than 6,000 vessels visiting and anchoring outside every year.
Green-port strategy
Its green-port strategy is said to be well developed, exploring a wide range of emissions-reduction opportunities, including quayside electrification, the use of alternative fuels and lower-carbon power supplies, and sustainable waste management.
Port chief executive Bob Sanguinetti said: "Innovative thinking and practices are crucial if we're to achieve a green maritime industry. We look forward to working with Stillstrom to develop low-carbon power supply and reduce emissions from vessels on standby outside our port.
"Pioneering projects like renewable offshore charging will help to make our vision of becoming Scotland's premier net-zero port a reality."
Stillstrom chief executive Kristian Jorgensen added: "We are extremely pleased that the Port of Aberdeen and Stillstrom have entered into this collaborative memorandum of understanding.
"The feasibility study is a cornerstone in our go-to-market strategy for our ports-and-hub segment. Together with the Port of Aberdeen as a close partner, we will be able to map and show the true value of utilising electricity for idling vessels - which we expect will not only support the journey towards a net-zero ocean economy and a better near-coastal environment, but also an economically-attractive solution for vessel owners."
