Petrochina International blends over 30,000 mt of marine biofuel since March

Petrochina International Co Ltd recently said it has blended more than 30,000 metric tonnes (mt) mt of biofuel since completing the country’s first biofuel marine fuel blending operation on 13 March.

The company said the milestone demonstrates its ability to conduct continuous and large-scale biofuel marine fuel blending operations.

The company has been developing marine biofuel blending operations at China (Zhejiang) Pilot Free Trade Zone, leveraging storage and logistics facilities at its Aoshan base.

Its latest product, B24 marine fuel containing 24% biofuel component, meets relevant International Maritime Organization (IMO) requirements and marine fuel standards, according to the company. It said the product can be supplied for bunkering vessels operating on international routes.

It has used its global trading network to secure feedstock supplies and support cost control and supply security for the blending operations, it added.

The company said the large-scale blending of its marine biofuel products marks a development in China’s marine biofuel blending market.

It plans to work with upstream and downstream businesses within its group to support the development of Zhoushan Port as a major bonded marine fuel bunkering hub and contribute to its parent group’s transition towards lower-carbon energy.

Manifold Times previously reported China (Zhejiang) Pilot Free Trade Zone launching the first pilot programme for marine biofuel blending in China with the completion of the first batch of B24-HSFO. 

The launch was marked with the blending of 2,000 mt of biodiesel and 6,300 mt of high sulphur fuel oil (HSFO) in storage tank F-02 of Sinochem-Xingzhong Oil Staging (Zhoushan), producing 8,300 mt of B24-HSFO. 

Manifold Times also reported the first cross-regional bonded bunkering operation of blended biofuel in East China was successfully completed at the Meishan Port Area of ​​Ningbo-Zhoushan Port. 

The B24-HSFO used in the bunkering operation was supplied by the Aoshan Petroleum Base in Zhoushan from the first pilot programme for marine biofuel blending in China.
