ABL investigates photo voltaic powered chilly ironing at Mombasa Port
A feasibility examine carried out by power and marine consultancy ABL Group investigated two attainable brownfield websites for the set up of a photo voltaic photovoltaic (PV) plant to generate renewable power powered shore energy – or ‘chilly ironing’ – on the Port of Mombasa, Kenya.
The undertaking was commissioned following the proposed introduction of the Inexperienced Ports Coverage by the Kenyan Ports Authority, which foresees that each one ships within the port of Mombasa should flip off the ship’s turbines and function from shore energy.

“A examine carried out in 2021 exhibits that 25 p.c of the emissions of ships are produced whereas idle in port. Using electrical energy from the shore brings vital reductions in emissions. p.c clear within the native photo voltaic PV sources, making an ideal inexperienced contribution to the coastal energy system,” stated Aimee Besant, head of power storage at ABL Group.
As a part of the examine, ABL’s renewable power specialists carried out a feasibility examine for the shopper to evaluate the feasibility of putting in a 5-10 MWp photo voltaic plant, the power from which can be utilized to put in a inexperienced power shore energy system. The scope of labor consists of offering a sign of the price of a correctly sized photo voltaic plant, and evaluating the typical consumption wants of the ship and wider power wants of the port and harbor.
The outcomes of the examine assessed two potential brownfield websites that have been thought-about viable choices for photo voltaic PV plant improvement, following desktop evaluations by the ABL group. The work concerned growing a conceptual design for every website, every designed to maximise PV output from the websites. The design outcomes have been in contrast with the ship and port consumption wants and the native price of heavy gasoline oils to find out that, on a kWh foundation, the mixture of PV-generated and grid equipped shore energy can be efficient. the fee in comparison with conventional onboard turbines.
“The examine discovered {that a} vital discount within the native burning of heavy gasoline oils might be obtained from the usage of chilly ironing, leading to an enchancment in native air high quality. Whereas the chilly that steeling is extra thought-about in several nations, this undertaking exhibits the dimensions of the chance for different ports world wide to discover the set up of shore energy generated from their native inexperienced power useful resource, in addition to elevated potential when mixed with power storage options corresponding to lithium batteries or hydrogen,” provides Aimee Besant.
Though this examine was designed to research the feasibility of photo voltaic PV generated chilly iron, it was prolonged to research the feasibility of further sources of renewable energy or power storage.
ABL Group gives a variety of technical providers throughout renewable power together with wind, photo voltaic, power storage and hydrogen, in addition to electrical engineering and cables, and maritime elements, to supply complete help for the set up {of electrical} options on the coast, from the primary R&D, idea improvement, engineering, building.
