Environmental and price challenges are driving the interest in alternative ship fuels, but the number of realistic candidates is small, finds the latest study Alternative Fuels and Technologies for Greener Shipping of classification society DNV GL.

The study believed liquefied natural gas (LNG), liquefied petroleum gas (LPG), methanol, biofuel and hydrogen to be the most promising candidates to be used by the shipping industry as an alternative marine fuel.

“Among them, LNG has already overcome the hurdles related to international legislation, and methanol and biofuels will follow suit very soon. It will be a while before LPG and hydrogen are covered by appropriate new regulations within the IMO IGF Code, as well,” it finds.

“The existing and upcoming environmental restrictions can be met by all alternative fuels using existing technology. Fuel cells can use all available alternative fuels and achieve efficiencies comparable to, or better than, those of current propulsion systems.”

However, the study notes fuel-cell technology for ships to be still in its “infancy”. The most advanced developments to date have been achieved by the projects running under the umbrella of the e4ships lighthouse project in Germany, with Meyer Werft and ThyssenKrupp Marine Systems heading the projects for seagoing ships.

Wind-assisted propulsion, meanwhile, could potentially reduce fuel consumption, especially when used for slow ships, but the business case remains difficult.

Batteries as a means to store energy can be considered as an alternative fuel source in the widest sense. Still, they have major potential for ships running on short distances and can be used to boost the efficiency of the propulsion system in any ship, but are unable to substitute fuel in deep-sea shipping.

With low-sulphur and alternative fuels becoming more widely available, the well-known combined cycle gas and steam turbine technology represents a viable alternative for highpower ship propulsion systems.

“All fuel alternatives discussed here could meet the foreseeable volume requirements for shipping over the coming years,” it notes.

“A major increase in consumption would require an appropriate increase in production capacity; the only exception is LNG, which is available in sufficient quantities today to meet the potential requirement of the shipping industry for many years.

“Without taxation or subsidies, renewable fuels will find it difficult to compete with the prices of conventional fossil fuels. “

In short, the study finds LNG and LPG to be the only fossil fuels capable of achieving a reasonable CO2 emissions reduction.

CO2-neutral shipping seems possible only with fuels produced from regenerative sources.

If the shipping sector resorts to synthetic fuels produced from hydrogen and CO2 using regenerative energy, the available alternatives will be liquefied methane (which is very similar to LNG) and diesel-like fuels.

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.
