Hong Kong-based marine fuel supplier Chimbusco Pan Nation (CPN) on Wednesday (10 June) said it has successfully delivered B100 marine biodiesel to an oil tanker for the first time, bunkering the vessel TORM CORRIDO on 8 June. The operation marked a significant expansion of CPN’s B100 capability, bringing oil tankers into the range of vessel types it can serve with fully compliant, certified biodiesel supply in Hong Kong. The achievement reflects a broader surge in market demand. Since CPN launched its B100 marine biodiesel service in January 2026, operator confidence has grown rapidly, and total volumes delivered in the second quarter of 2026 have already exceeded first-quarter totals by more than 300%. “Total B100 marine biodiesel volumes in Q2 2026 have already exceeded Q1 by more than 300%, driven by the trust of partners like TORM,” CPN said. The operation was carried out by CPN’s dedicated bunker tanker Guo Si , fully upgraded in compliance with the IMO IBC Code and Hong Kong Cap. 413E. “As Hong Kong’s only Type II-certified bunker tanker for B100 operations, Guo Si brings the specialist capability to handle pure biofuels safely and compliantly across vessel types,” the company added.   Photo credit: Chimbusco Pan Nation Published: 11 June, 2026
