Pilbara Clean Fuels pursues development of electrified LNG plant

The project will provide an Australian LNG fuel supply capability through a new facility for the conversion of pipeline natural gas to LNG, responding to market demand for cleaner marine bunker fuel for dry-bulk iron ore carriers operating ‘round-trip’ voyages between the Pilbara and Asia.

Market studies show increasing worldwide adoption of LNG as a marine fuel, with supply availability one of the key drivers. The base-case plant capacity is 0.5 million tpy, with market analysis for Port Hedland alone (not counting other major Pilbara ports) indicating potential demand of 1 million tpy by 2030.

A key feature of the project is an electrified plant with outsourced power supplied predominantly from renewable sources. The design intent is to significantly reduce Scope 1 and Scope 2 emissions compared to conventional LNG plants. Thereby providing an ability for round-trip voyages bunkering in Port Hedland to achieve substantially lower overall greenhouse gas (GHG) lifecycle emissions than other options.

The LNG refuelling concept is based on ship-to-ship bunkering of vessels while at anchor off Port Hedland.

Oceania Marine Energy is developing a LNG marine fuel bunkering service capability based on the charter, ship management and operation of purpose-designed LNG bunker vessels. The vessels are to be provided by Norwegian ship-owner, Kanfer Shipping.

RINA is developing a concept for a new 209 000 DWT ‘Newcastlemax’ dry-bulk ship design with an innovative LNG marine fuel system involving pre-combustion carbon removal and hydrogen production, with the objective of meeting and exceeding IMO 2050 emissions reduction marine vessel Carbon Intensity Index (CII) objectives.

The RINA fuel system concept involves the capture, onboard storage and offloading of liquefied carbon dioxide or solid carbon at loading or discharge ports for onshore handling, monetisation or disposal. The concept provides a credible line-of-sight pathway to ‘zero emissions’ for the application of LNG as a marine fuel.

By solving the historic criticism of LNG as being only a ‘transition fuel’, rather than having a long-term future as a ‘zero emissions’ fuel, this solution is likely to be welcomed by the marine engineering community due to the extensive maritime operational experience of LNG and its known safe handling characteristics.

The Pilbara to Asia dry-bulk trade route is particularly suited for early adoption of the pre-combustion carbon removal and hydrogen production onboard concept due to proposed availability of low carbon intensity LNG bunkering at Port Hedland, along with an ability for offloading carbon dioxide or solid carbon and a variety of monetisation or disposal options.

Recognising the complementary aspects of their respective project interests and business objectives, PCF, Oceania and RINA have entered into a Memorandum of Understanding (MoU). Under the terms of the MoU, PCF, Oceania and RINA have agreed to collaborate to develop an ‘end-to-end’ low-carbon profile LNG production and marine vessel bunkering capability concept for the port of Port Hedland. Furthermore, RINA’s 209 000 DWT Newcastlemax dry-bulk vessel design and fuel system design concept provides a path to ‘zero emissions’ for the adoption of LNG as a marine fuel on a 2050 timeframe.

PCF Managing Director, Robert Malabar, commented: “Along with our existing partners Oceania, we are delighted to have formed the new collaborative relationship with RINA. The partnership has the ability to demonstrate an attractive commercial development strategy to meet not only the immediate needs of IMO 2030 emissions compliance, but the engineering step-change needed to create a practical path to IMO 2050 net zero emissions objectives. We know the maritime community is happy with LNG as a marine fuel. We believe the outcome of the studies should provide compelling argument in support of the Western Australian Government’s May 2020 announcement to 'create an international LNG fuelling hub in the Pilbara'.”
