Zero-Emission Voyage in the Greater Bay Area | CSSC CSEI Pure Electric Power System Powers Hong Kong Green Shipping Project

Recently, the first batch of five pure battery-powered vessels for the Hong Kong Environmental Protection Department’s waste transportation and power generation project were successfully delivered in Guangzhou.

The five vessels — “Xin Bei Yu,” “Yung Shue Wan II,” “Mui Wo II,” “Sok Kwu Wan II,” and “Yu Lian II” — were funded by Yuefeng Environmental Power Co., Ltd. (acquired by Grandblue Environment in 2025). The vessels were constructed by Guangzhou Haihuang Technology Co., Ltd. and designed by CIMC Ocean Engineering Design & Research Institute Co., Ltd. They will primarily be used for transporting waste containers between North Lantau and the outlying islands of Hong Kong.

All five vessels are equipped with the S-Renewable new energy power system developed by CSSC CSEI. Leveraging its independently developed DC grid variable-frequency electric control technology and marine containerized mobile power supply technology, the system enables zero-emission operation, low noise, and high reliability throughout the entire voyage and operational process, contributing to the green transformation of the shipping industry in the Guangdong–Hong Kong–Macao Greater Bay Area.

The “Xin Bei Yu” is the first fully electric cargo vessel operating in Hong Kong. It complies with CCS classification standards and the Hong Kong Local Vessels Ordinance, and has obtained additional notations for In-Water Survey and Battery Power propulsion.

The successful delivery of this batch of electric vessels marks another significant expansion of CSSC Saisiyi’s electric cargo ships from inland river applications to the coastal sector. It achieves an upgraded application of containerized mobile power systems, transitioning from inland river containers to sea-going vessel containers, and promotes the large-scale deployment of battery propulsion technology across all scenarios.

This important breakthrough not only demonstrates CSSC Saisiyi’s leading capabilities in the research, development, and manufacturing of electric cargo ship power systems, but also actively implements the concept of green shipping, laying a solid foundation for the maritime industry’s environmental transformation.
