Microgrids at large ports
When will it become accepted practice that large ports are retrofitted with microgrids?
Ports are the sites of major pollution, where large vessels continue to run their engines even while at berth, and heavy-lifting work is being performed by diesel-powered cranes.[1,2,3,4] As the maritime industry explores ways to decarbonize, microgrids that at ports can play a supplementary role to existing electric grids with an enhanced energy storage systems.
Microgrids-originally developed to manage industrial operations in remote areas-are designed to draw and manage energy from renewable sources such as solar, tidal, wind, hydrogen or other electrofuels that is generated around the clock.[5,6] Microgrids at ports will enable the electrification of lifting and transport machinery, and will also enable large cruise ships to transition to cold ironing, a practice that is currently limited because city-grids cannot bear the load.
The global microgrid market is growing at annual rate of 11.26%, and projected to reach $46bn by 2025.[7,8] Ongoing challenges at ports include the space, cost, and installation of renewable energy generating technologies and microgrid control systems, and the know-how to manage it all.
