A white paper published by classification society DNV on Wednesday (20 April) has concluded that developing “green” drop-in fuels alone may not be enough for the naval segment as there are other practical considerations such as logistics and fuel availability in determining the feasibility of different low- or zero-carbon fuels. 

The white paper titled “Alternative Fuels for Naval Vessels” explores how naval vessels can minimise their environmental impact without increasing their operational vulnerability.

Navies around the world are becoming increasingly aware that they will also be affected by the decarbonisation challenge facing the maritime world. 

However, to fulfil their defensive purpose, naval vessels must also meet specific requirements which add complexity to their search for the most sustainable fuel types, says DNV. 

Despite navies not being subject to the same scrutiny as the commercial shipping industry, they are nevertheless coming under growing societal pressure to reduce their environmental footprint. 

Furthermore, they will need to face potential global challenges affecting logistics and, therefore, fuel availability.

This has implications for the design of future naval vessels and developing  “green” drop-in fuels alone may not be sufficient. 

While the scientific and practical advancements made in developing and testing alternative fuels and propulsion technologies for private sector shipping are of great value to the military, combatant naval vessels must be able to operate under direct threat, at high speeds, and for extended periods of time without refuelling.

“Alternative fuels are the most effective measure to fully decarbonise in the future, but practical considerations such as logistics, fuel availability, fuel change flexibility and design impacts are critical factors in determining the feasibility of the different low- or zero-carbon fuels for the naval segment,” said Christian von Oldershausen, DNV Maritime Segment Director for Navy. 

“The new paper evaluates different fuel options to provide a solid decision support for newbuilds and vessels in operation.”

“This white paper provides an excellent starting point for us to work together to protect our environment and at the same time ensure the operational readiness of our navies,” said Jan Christian Kaack, Vice Admiral, Chief German Navy, Commander Fleet and Supporting Forces. 

The white paper is based on a wide range of public-domain information sources as well as a survey conducted among 130 stakeholders from 12 countries to ascertain current trends and expectations.

It summarises recent technology developments; discusses current and emerging fuel choices including their pros and cons, as well as their technical and military implications; looks at other carbon abatement and efficiency enhancing measures; and analyses the current navel fleets and their respective uptake of alternative fuels.

The authors differentiate between the needs of combatant vessels and those of auxiliary, non-combatant ships, which usually operate closer to shore and travel shorter distances. Special attention is given to the unique operating patterns of submarines and the resulting requirements.

The document sees significant potential – especially for non-combatant ships – to adopt alternative fuels which are available today and increasingly used by the merchant fleet. In the survey conducted for this white paper, more than 83% of respondents saw biofuels as a more realistic option for naval ships than ammonia, methanol, hydrocarbons or other power sources.

The paper also explores the advantages and disadvantages of nuclear propulsion, which has been used by the United States Navy for decades because of the speed and endurance it gives to combatant vessels.

Shell expands LNG bunkering footprint in Spain with Valencia

British oil giant Shell on Thursday (13 August) said Valencia has joined its growing network of bunkering locations, making LNG available as a marine fuel.

The successful completion of the first LNG bunkering operation in Valencia marked an important milestone for Spain and further strengthened Shell’s LNG supply capabilities across the Mediterranean. 

In a video shared by the company, bunkering vessel Alice Consulich was shown supplying an undisclosed volume of LNG to the container ship MSC Sabrina.

“As one of the region’s key maritime hubs, Valencia expands the options available to shipowners seeking LNG supply along major shipping routes,” Shell said in a social media post. 

Shell said the achievement reflected the strong collaboration across the maritime value chain, including MSC Mediterranean Shipping Company, the Port of Valencia and Fratelli Cosulich Group.

“We look forward to making more LNG bunker deliveries in Valencia and across the Mediterranean as LNG infrastructure and capabilities continue to expand,” the company said.

Stabilis Solutions enter 10-year LNG bunkering supply deal for Port of Galveston

Power LNG (Power LNG) and Mexico’s LNG infrastructure and downstream natural gas company Énestas on Wednesday (12 August) announced the execution of definitive agreements establishing a strategic partnership to accelerate the development of LNG infrastructure at the Port of Galveston.

Under the agreement, Énestas will provide capital, LNG transportation and storage equipment, and downstream operating expertise to support the development of the Harborside Terminal and Project Seawolf, Power LNG’s planned LNG liquefaction and marine bunkering facility on Pelican Island.

The partnership creates an immediate pathway to begin LNG distribution by truck while Project Seawolf is under development, supporting marine fueling, virtual pipeline customers, industrial users, and LNG exports throughout the Gulf Coast, Latin America, and the Caribbean.

“Our vision has always been to establish Galveston as the premier LNG hub for the Gulf Coast,” said Austin Terry, Founder and CEO of Power LNG. 

“Énestas brings years of operational experience, proven LNG infrastructure, and a talented team that understands how to deliver LNG safely and efficiently. Together, we can immediately begin serving customers while laying the foundation for one of the most strategic LNG bunkering facilities in North America.”

Project Seawolf will provide LNG for marine bunkering, truck loading, virtual pipeline distribution, and international exports. The facility is strategically located at the Port of Galveston, serving one of the fastest-growing cruise, cargo, and energy corridors in the United States.

For Énestas, the transaction represented an important milestone in the company’s international growth strategy.

“This partnership represents a natural evolution for Énestas as we expand our downstream LNG business into the United States,” said Caio Zapata, Chief Executive Officer of Énestas. 

“For more than a decade, Énestas has developed and operated LNG infrastructure throughout Mexico, helping customers transition to cleaner, more reliable energy. Partnering with Power LNG allows us to leverage that experience in one of the most attractive LNG markets in North America. We see tremendous opportunities in marine bunkering, virtual pipeline logistics, industrial LNG supply, and exports to Latin America and the Caribbean, and we are excited to build that future together.”

The companies expect the partnership to support near-term LNG truck loading operations while advancing the long-term development of Project Seawolf, which is designed to become a regional hub for LNG production, marine fueling, and distribution.

The collaboration also establishes a platform to pursue additional downstream LNG opportunities throughout the Gulf Coast, utilising Énestas’ operational expertise together with Power LNG’s project development capabilities.
