Eco Marine Power - who create renewable energy solutions to encourage "sustainable shipping" - have developed a vessel that can be powered with the renewable energy source.
Writing about the ship on their website, they shared: "The patented EnergySail is revolutionary rigid sail device designed by Eco Marine Power that allows ships to harness the power of the wind and sun in order to reduce fuel costs plus lower noxious gas and carbon emissions. The patented EnergySail is unlike any other sail - it can be used even when a ship is at anchor or in port and has been designed to withstand high winds or even sudden micro-bursts.
"The EnergySail can be fitted with a range of renewable energy technologies such as solar panels or wind power devices. It is a truly unique renewable energy platform specifically designed for shipping that can be fitted to a wide variety of vessels from large Capesize bulk ore carriers and RoRo vessels to naval and coastguard patrol ships."
The sail can also be retro-fitted to other boats and thus can be upgraded as of when newer technology becomes available.
They added: "The flexible nature of the EnergySail design will also allow for it to be upgraded during the life-cycle of the ship it is fitted to so that newer technologies can be incorporated as they become available such as more efficient solar modules or panels.
"It has also been designed so that it will require little maintenance and be robust enough to withstand the harsh conditions of an operational life at sea."
