The grant will also go towards the UK’s greenest cruise terminal at a port in Southampton, which opened in July.
Maritime Minister Robert Courts showed his support for the opening of the Horizon terminal at the Port of Southampton.
The terminal is the first of its kind which uses solar panels and clean energy shore power plug-in charging for ships.
According to the Department for Transport, the £55million facility – built in partnership between MSC Cruises and Norwegian Cruise Line Holdings – is leading the way in green cruising.
This comes as the UK sets to eliminate all emissions from shipping by 2050.
