The world’s largest solar-powered car carrier is China’s Yuan Hai Kou (often written as Yuanhai Kou).
It is operated by Guangzhou Yuanhai Automobile Shipping Co., Ltd., a joint venture under China COSCO Shipping Corporation Limited.
This Pure Car and Truck Carrier runs on solar power and supports the industry’s decarbonization goals, in line with IMO Targets.
The groundbreaking vessel was designed to meet the growing demand for vehicle shipments, especially to cater to the increasing Chinese automobile exports.
Yuan Hai Kou combines fine engineering with a hybrid solar and LNG power system and enables low-carbon shipping.
It was constructed by Guangzhou Shipbuilding International (GSI), a subsidiary of the state-owned China State Shipbuilding Corporation.
The world’s largest solar-powered car vessel completed its maiden voyage in July 2025 when it reached Piraeus Port, Greece, with 4000 chinese vehicles.
Dimensions and Cargo Capacity
The Yuan Hai Kou has an overall length of 199.9 m and a beam of 38 m. It has a 10 m draft when it is fully loaded.
