The Bottleneck in Green Fuel Supply for Shipping Industry

DNV, a major classification service for the maritime industry (it stands for Det Norske Veritas), is reporting that accounting for newbuilds that can burn alternate green(er) fuels, the bottleneck will be the supply of these fuels for maritime use.

It calls the phenomenon a “fuel transition tipping point”. It’s a strong demand signal for fuel producers. The graph shows the exponentially rising number of alternative fuel ships in the fleet, and adds the order book for the future. Methanol seems to be increasing quickly.

The infrastructure just isn’t there yet, and bunker operators and fuel producers need to step up their investments.

Green corridors are one approach that is gaining traction. In this scenario, several partners join forces with ports, fuel producers and bunker operators to make sure the infrastructure is there for fueling with green fuels on the route, usually point-to-point. Maersk has been a leader in this effort. Others are getting on board.

Mapping hidden emissions in shipping supply chains

Firms need to document their Scope 3 emissions. It’s especially true in Europe where the EU Corporate Sustainability Reporting Directive (CSRD) mandates reporting.

Unfortunately in the US the government is walking back any disclosure regulations for greenhouse gas emissions. But many companies operate multinationally, and procurement procedures are so complex that it becomes very difficult to know what suppliers are actually doing about greenhouse gas and other emissions.

That’s why ways to collect and validate the required supplier data, as well as your own, are important. A well-designed system can make the task remarkably easier.

Enter Danish climate specialist ReFlow and Procureship, an e-procurement platform supplier. Their partnership has created as system called EmissionPassport, a structured way to collect product-level Scope 3 emissions data from suppliers as well as your own vessel-level activities. The makers say that the climate data is not used to make procurement decisions in the system, but does insure that the measurable climate impact numbers are available for reporting.

The system supports alignment with the International Marine Purchasing Association (IMPA) and its Maritime Environmental Footprint (IMEF) Initiative, which provides a shared climate data standard for maritime procurement.

See this Price Waterhouse Report for more information about the CSRD.

LNG bunker supply chain emissions

It’s difficult to quantify the emissions load generated by LNG bunkering for oceangoing ships. Rystad Energy has released a study of this from Well to Tank.

Liquefied Natural Gas (LNG) is currently an important maritime fuel as the industry tries to transition to a lower carbon footprint. LNG-fuelled ships now account for over 20% of the current order book.

The question is this: how does LNG perform in terms of greenhouse emissions? One needs to consider how it’s produced (Well!), transported, liquefied, stored, and processed for bunkering, as well as the loading process. That’s the study’s focus.

They found 13.9 grams of carbon dioxide equivalent per megajoule heating value, known as LHV. This broke down into 4.2 gCO23/MJ, for upsteam; 1.3 for transportation and processing; 5.9 for liquefaction; 1.8 for shipping and distribution; and 0.7 for bunkering operations.

The total of 13.9 compares with the FuelEU Maritime figure of 18.5 gCO2e/MJ, which Rystad says is too high.

A key quote from the article:

Rystad’s Vice President Emissions Research, Patrick King, commented: “Our analysis is based on asset-level data that ties specific gas fields to liquefaction facilities. This approach, supported by satellite-detected methane plume data and reported asset information, gives a more accurate picture of the LNG actually used for bunkering, rather than relying on outdated or overly broad averages.”

It seems like the right way to do the analysis.
