Bunker Fuel

Scientists use leftover cooking oil, lamb fat and agricultural waste to develop greener marine fuel

Waste pellets were treated in Aston University’s pyrolysis-based reactor which heated them up to 500 °C to convert them into bio-oil.

UK-based Aston University on Thursday (1 February) said its scientists have blended leftover cooking oil, lamb fat and agricultural waste to develop a cleaner bunker fuel for ships.

The researchers have mixed waste pellets with either used oil or animal fat to develop a form of energy which meets international marine fuel standards.

The team combined waste material supplied by a Dutch anaerobic digestion plant with used oil or fat to create a blend which could be a replacement for bunker oil.

Their research “Investigation of anaerobic digested pyrolysis oil and waste derived biodiesel blends as sustainable fuel for marine engine application” has been published in the journal Fuel.

The waste pellets were treated in Aston University’s pyrolysis-based reactor which heated them up to 500 °C to convert them into bio-oil.

Solvents were added to the bio-oil which was then blended with the used cooking oil or fat to create the fuel.

Dr Abul Kalam Hossain, senior lecturer in the Department of Mechanical, Biomedical and Design Engineering, said “Over the past ten years both the volume of marine transport and the corresponding greenhouse gas emissions have increased steadily.

“We knew of the potential of pyrolysis oils as renewable biofuels for use at sea in diesel engines. However, due to their low energy content, high acidity and viscosity we knew they needed to be improved.”

The researchers created five blends adding differing amounts of bio-oil, solvent and oil or fat and stored them in the dark for eight months.

Tests showed the blends had improved their heat value, viscosity and density by around 25 to 40% and complied with Marine Fuel Standards (ISO 8216 and ISO 8217) for use in diesel engines and boilers.

The paper states the oil blends can be used in stationary diesel engines as well as marine diesel engines for power generation.

The research illustrates how biomass pyrolysis technology has developed into a sustainable technique which can turn food and agricultural waste into bio-oil. The study’s results could eventually contribute to better global air quality.

The Aston University research team worked alongside academics at the School of Architecture, Technology and Engineering University of Brighton, Indian Institute of Technology Madras, India and the College of Engineering Guindy, Anna University, Chennai, India.

PIL's LNG dual-fuel boxship “Kota Elok” arrives in Singapore on maiden call

Singapore-based Pacific International Lines Pte Ltd on Monday (20 July) said its first 13,000 TEU LNG dual-fuel container vessel, Kota Elok, recently made her maiden call to Singapore on 15 July.

As the first of 13 new 13,000 TEU vessels joining its fleet, Kota Elok is equipped to operate on liquefied natural gas (LNG) and low-sulphur fuel oil that helps reduce our greenhouse gas emissions. 

The vessel also incorporated energy-saving features and digital technologies to reduce fuel consumption and enhance operational performance, as well as a bow windshield to improve aerodynamics, contributing to improved fuel efficiency and lower emissions over the course of long-haul voyages.

“Following Singapore, Kota Elok will continue her voyage on our East Coast Service 1 (ES1) route to South America, calling at ports in Brazil, Uruguay, and Argentina before returning to Asia,” the company said in a social media post. 

Kota Elok also became PIL’s first vessel to receive Lloyd’s Register certification for compliance with the IACS UR E26 and UR E27 cyber security requirements.

Developed by the International Association of Classification Societies (IACS), UR E26 and UR E27 are mandatory cyber resilience requirements for newbuild vessels contracted from 1 July 2024.

CIMC SOE secures order for 12,000-cbm LNG bunkering vessel from Sinopec Clean Energy

China’s Nantong CIMC Sinopacific Offshore & Engineering Co., Ltd. (CIMC SOE) recently signed a contract with Sinopec (Beijing) Clean Energy Co., Ltd. to build a 12,000-cubic metre (m3) LNG bunkering vessel, according to Chinese maritime media.

The vessel is scheduled for delivery in 2028 and will support Sinopec’s efforts to expand its presence in the marine clean energy sector.

Once operational, the vessel is expected to strengthen Sinopec’s domestic coastal LNG bunkering network and help address gaps in China’s LNG bunkering infrastructure.

With this signing , CIMC Pacific Offshore Engineering’s LNG bunkering vessel orderbook is further strengthened, maintaining its leading position in the global market for small and medium-sized LNG bunkering vessels.

The contract also marked another milestone for CIMC SOE, which has seen a sharp increase in orders and business performance this year amid a surge in domestic LNG vessel demand.

ABS awards AiP to Korean institute for SMR-powered container ship concept design

Korea Research Institute of Ships & Ocean Engineering (KRISO) on Thursday (16 July) received Approval in Principle (AiP) from the American Bureau of Shipping (ABS) for its concept design of a 15,000 TEU Small Modular Reactor (SMR)-powered container ship utilising Molten Salt Reactor (MSR) technology.

KRISO said the AiP recognises the technical feasibility and safety of its concept design, marking an important milestone toward the development of next-generation nuclear-powered commercial ships.

“This achievement demonstrates international recognition of KRISO’s technological capabilities in the rapidly evolving field of nuclear-powered shipping, supporting the transition toward low-carbon maritime transport,” it said. 

Building on this milestone, KRISO will continue advancing basic and detailed ship design, paving the way for future demonstration and commercialisation of SMR-powered vessels. 

Through continued R&D and international collaboration, KRISO remains committed to strengthening next-generation maritime technologies and contributing to the safe deployment of nuclear propulsion in the maritime industry.
