A group of Scottish renewable and maritime companies are aiming to lead the way for a circular economy approach to port decarbonisation.
Backed with a £535,000 government grant, Forth Ports, Waterwhelm, Logan Energy and PlusZero will embark on a year-long trial, leading to a state-of-the-art demonstrator system for green hydrogen shore power being delivered. Marine vessels, when berthed at the Port of Leith, will be able to use it, paving the way for diesel-powered systems currently in use on some quaysides to be left redundant.
Waterwhelm’s specialist water treatment technology will turn wastewater from the Seafield treatment works site in Edinburgh into fresh re-use water. Logan Energy’s electrolyser technology will be used to create hydrogen. This will then be used as a clean fuel in PlusZero’s combustion engine.
Building this circular economy approach to port decarbonisation, the partners hope it will pave the way for a similar approach across the country, one that can be used especially in remote locations or areas where a connection to the main electricity grid is not available.
