Autonomous hydrogen submarine among winners of government competition campaign aimed at tackling maritime transport emissions.
A consortium of start-ups has been awarded £ 380,000 to develop the sub-delivery of packages without a captain or a crew.
Call it with the thought of the blue seas - the sous-marin will follow the maritime routes but 50 meters below the surface.
It will be able to deliver cargo in shallow waters where container ships cannot operate.
Then it will dive under the waves to weather storms in the open sea. .
The company that won the grant, Oceanways, flagged Belfast to Glasgow as a possible route for the submarine.
The grant is part of a £ 23million UK fund for environmental maritime projects.
The money is too small to cut carbon emissions on time to avoid dangerous global warming, but this demonstrates the explosion of innovation and climate change prompted.

The submarine cargo ship (if it has already been built) to be powered by "green " hydrogen from renewable energy.
Creators say it will also collect micro plastic from the water column and feed the data to researchers.
Oceanwayssays he could swim under the ice cap.
'Whiskey would be a good candidate '
Company founder and CEO Dhruv Boruah said that the unmanned boat would not compete with freighters, but instead focus on "short and precise " journeys.
But what kind of cargo will the submarine be carrying?
"This is what we are going to find out over the next few months " he told Hfrance.fr's Good Morning Ulster program.
"I think whiskey would be a goo d candidate. "
Among the other winners is an electric charging stationthan connected to an offshore wind turbine where electric boats will power at sea.
The company behind the project said it would initially deliver savings of over 1,270 tonnes of emissions of CO2e per year.
Ships will be able to moor and hook up with a semi-automatic system before loading and sailing.
Maritime transport currently produces around 3% of global emissions, but UK government aims to become the world leader by supporting a zero emissions plan by 2050.
Critics say Britain is not doing enough in the short term to achieve this objective.
