BHP, Australia's BHP, explores ship biofuel made from animal fat and cooking oil

BHP Australia and the Global Centre for Maritime Decarbonisation in Singapore have refueled a cargo ship with biofuel that is made from waste cooking oil and animal fat as part of a pilot project.

As the shipping industry looks for alternatives to conventional marine diesel to reduce emissions, it is necessary to investigate novel blends.

Due to a lack of supply, companies are now looking at other waste-based feedstocks, such as animal fats.

The Berge Lyngor owned and operated Berge Bulk, a BHP chartered bulk carrier, used the blend to transport iron ore from Western Australia to China.

The ship bunkered in Singapore 'early May' with a 'full biofuel blend consisting 50% tallow-derived Biodiesel supplied by HAMR Energy and 50% used cooking oils supplied by Mitsui & Co. Energy Trading Singapore.

BHP and GCMD stated that the pilot will evaluate how biofuels can be blended, handled, and introduced in real-world conditions using existing bunkering facilities applied to used cooking oil.

The project will identify solutions for challenges relating to fuel quality, handling, traceability, and vessel performance.

The study will also assess potential problems that could arise from the use of biofuels made from different feedstocks. These include corrosion due to oxidation, and fuel system clogging from wax formation.

BHP and GCMD stated that using the bio-blend fuel can reduce greenhouse gas?emissions for one voyage by 79% compared to sailing on conventional low-sulphur fuel oil. Fuel production, delivery, and use onboard vessels are all covered by Well-to Wake. (Reporting and editing by Kevin Buckland; Jeslyn Lerh)
