Japanese Organizations Launch Groundbreaking Initiative for Zero-Emission Shore Power Systems

A group of Japanese organizations have embarked on a groundbreaking initiative to advance standardized, zero-emission shore power systems. This comes as Japanese ports and coastal industrial zones account for approximately 60% of the country’s CO2 emissions and are therefore a prime target for decarbonization. With Japan aiming to achieve carbon neutrality by 2050, shore power has emerged as a crucial focus, as diesel generators on docked ships contribute to around 40% of CO2 emissions in ports and also emit harmful substances like NOx and SOx, impacting the surrounding environment.

The organizations involved in this pioneering effort include e5Lab, Marindows, e-Mobility Power, CHAdeMO Association, The Japan Ship Technology Research Association, Mitsubishi Ship Building, Development Bank of Japan, City of Kobe, Port and Harbor Bureau, and City of Yokohama, Port and Harbor Bureau. Their collective objective is to establish and maintain a strategic ecosystem for zero-emission chargers, develop user-friendly charging systems, and incentivize more ships to utilize these services. The ultimate goal is to achieve zero emissions from ships in port areas, facilitate the adoption of electric vehicle (EV) ships, expand the use of renewable energy, and address global and local environmental issues.

The system will comprise an onshore power station with standardized chargers and billing systems, a shipboard power receiving module with standardized and modularized hardware and software, and high-capacity communication between ship and shore through a standardized communication system within the port. In the initial phase, by fiscal year 2025, the partners plan to install prototype standardized universal zero-emission chargers in the prominent Hanshin and Keihin Ports, which are both international strategic hubs for domestic and foreign freight and ships. Following this, the aim is to expand the chargers to other national and international ports.

This ground-breaking initiative holds immense potential in transforming the maritime industry and reducing carbon emissions. By implementing zero-emission shore power systems, Japanese ports can significantly contribute to the country’s decarbonization goals and lead the way towards a more sustainable future for the industry.
