The promotion of shore power technology is the best solution to reduce pollution from ships calling at the port. Through the "oil-to-electricity" approach, the replacement of energy by ships during the docking period can greatly reduce pollutant emissions from ships.

 

When the electricity price is low, the electricity is stored in the storage battery, and when the shore power is needed, the electricity is sent out. This is like equipping the traditional shore power system with a giant 'charger', which can not only play a role in the grid. The effect of peak cutting and valley filling has also reduced the cost of using shore power for ships.
