Ammonia power solutions firm Amogy Inc. on Tuesday (1 November) announced a strategic partnership and technology deployment project with Southern Devall, formerly Southern Towing Company & Devall Towing, with plans down the pipeline to create an ammonia-powered fleet. 

Southern Devall specialises in transporting bulk liquid chemicals and fertiliser products throughout the Mississippi River and Gulf Intracoastal Waterway System. With the successful integration of Amogy’s technology in a tank barge for the first time, this collaboration with Southern Devall will facilitate the commercial debut of Amogy’s ammonia-to-power technology in the global maritime market. 

Following the barge integration and demonstration, Amogy and Southern Devall plan to pursue retrofits of additional barges and tugboats, creating an ammonia-powered fleet that includes cargo transportation vessels as well as bunkering barges for efficient, emission-free refuelling of ammonia-powered ships.

Southern Devall currently services a significant portion of the ammonia production market and delivers ammonia to terminals for export and agricultural and chemical customers along America’s inland waterways. Amogy’s proprietary ammonia-to-power system converts ammonia into hydrogen for use in fuel cells or as a more energy dense method of long-distance hydrogen transportation.

The system, already demonstrated in a farming tractor and aerial drone, is now being scaled for use in larger applications, including ships and ammonia bunkering barges to support the maritime industry’s decarbonisation efforts. This partnership will provide Amogy with access to vast ammonia infrastructure as well as the Southern Devall team’s expertise in handling ammonia and maritime operations. 

Amogy and Southern Devall have initiated work on their first technology deployment, a retrofit of a barge that is anticipated to be completed by the end of 2023. An Amogy powerpack will generate the power needed to reliquefy ammonia as it heats up over the course of a voyage, instead of a diesel genset. The Amogy system will keep the ammonia tank pressure low, enabling Southern Devall to deliver ammonia to customers upon arrival and increase the utilisation and profitability of their fleet. Furthermore, Amogy’s system has already passed initial safety reviews and recently received Approval in Principle (AiP) from Lloyd’s Register, a maritime classification society, for a powerpack design similar to what the team will look to deploy in this project. 

“Southern Devall shares Amogy’s passion for driving innovation, making them the perfect strategic partner to support our commercial entrance to the U.S. maritime market,” said Seonghoon Woo, CEO of Amogy. 

“In collaboration with their team, we’ll have a first-mover advantage in this space through expanded access to the ammonia infrastructure and industry knowledge, setting us on track to demonstrate our platform’s operational capabilities in large maritime vessels.” 

“Amogy has built an impressive platform that our team believes is an ideal solution for introducing cost-efficient, zero-carbon bunkering and powering operations to the inland barge industry,” said Sam Lewis, Vice President of Engineering at Southern Devall. 

“Adopting their solution at scale in our fleet has both environmental and economic benefits through increased delivery volume. We look forward to demonstrating the value of ammonia-to-power solutions in our first project with Amogy and introducing industry and channel partners to these innovations.” 

In the U.S., the inland shipping sector is responsible for an estimated 6.2 million tonnes of CO2 emissions each year. Many operators in this industry rely on older, high-investment equipment, vessels and barges dating back to the 1960s.

The partnership between Amogy and Southern Devall will demonstrate scalable, cost-effective solutions for refurbishing fleets to improve quality and introduce zero-carbon power and bunkering capabilities. Current and future projects and demonstrations the companies are pursuing will enable commercialisation and broad adoption of ammonia-to-power technologies and keep the industry on track to meet the maritime shipping industry’s goal of cutting greenhouse gas emissions by at least 50% by 2050.

Singapore: FueLNG achieves 400th LNG bunkering operation milestone

Singapore’s licensed LNG bunker supplier FueLNG on Thursday (15 May) announced the successful completion of its 400th LNG ship-to-ship (STS) bunkering operation in the republic.

FueLNG, a joint venture between Keppel Offshore & Marine and Shell Eastern Petroleum Pte Ltd, marked the milestone with bunker tanker FueLNG Bellina successfully refuelling BYD Shenzhen, the world’s largest LNG-fuelled car carrier, at Singapore anchorage during its maiden voyage.

“With a capacity of 9,200 vehicles and equipped with dual-fuel LNG propulsion, the BYD SHENZHEN represents the next generation of low-emission maritime transport,” it said in a social media post. 

Shell said it supported BYD Shenzhen on its maiden voyage as the supplier of the LNG bunker fuel. 

“Like all LNG dual fuel vessels, BYD Shenzhen is on the pathway to net zero emissions. She can take bio-LNG, and in the future e-LNG, in her fuel mix for further emission reduction and regulatory compliance,” it said in a separate social media post.

Hong Kong: CPN hits new record for China's largest B24 biofuel bunkering operation

Hong Kong-based bunker supplier Chimbusco Pan Nation Petro-Chemical (CPN) on Friday (16 May) said it has set a record for China’s largest B24 marine biofuel bunkering operation.

CPN said it delivered 6,300 metric tonnes (mt) of B24-VLSFO in Hong Kong to container ship XIN LOS ANGELES on 15 May. 

The supply exceeded CPN’s previous record of 5,500 mt delivered to the same ship in February 2025.

“This collaboration reinforces CPN’s ability to execute large-scale marine biofuel bunkering with precision and reliability,” the company said in a social media post.

“By consistently supplying large volumes of B24 marine biofuel, CPN supports reduced carbon emissions and sustainable shipping practices globally.”

St1 delivers first locally produced biomethane to Swedish maritime sector for bunkering

Finnish energy company St1 and its venture St1 Biokraft delivered their own Swedish-produced liquefied biomethane, also known as bio-LNG, to the local maritime sector for the first time, according to Port of Gothenburg on Thursday (15 May). 

Terntank’s vessel Tern Ocean was bunkered with the biomethane at the Port of Gothenburg. 

St1 and St1 Biokraft are now aiming to become large-scale suppliers of biomethane for shipping, while the Port of Gothenburg continues to pursue its goal of becoming Scandinavia’s primary bunkering hub for alternative fuels.

The bunkering operation recently carried out at quay 519 in the Port of Gothenburg was an important pilot test for St1 and St1 Biokraft as suppliers of biomethane to the maritime sector. The operation also served as a pressure test of the collaboration required across all parts of the value chain, with Terntank, gas infrastructure owner Nordion Energi, and the producers themselves all playing crucial roles.

“In order to accelerate the maritime sector’s transition, it is essential that all actors across the value chain pull in the same direction, cooperate, and translate ambitions into practice. We are pleased to have all of this in place at the Port of Gothenburg,” said Therese Jällbrink, Head of Renewable Energy at the Port of Gothenburg.

“Liquefied biomethane is an important part of the fuel palette that must be available to support the shipping industry’s transition. It is one of the fuels the Port of Gothenburg is working with within the framework of green shipping corridors, aimed at creating the conditions for fossil-free logistics chains. This bunkering operation brings us another step closer to our ambition of becoming Scandinavia’s primary bunkering hub for alternative fuels.”

St1 and St1 Biokraft have ambitions to become large-scale suppliers of liquefied biomethane for the maritime sector, with several new production facilities planned across Sweden.

In 2026, energy infrastructure company Nordion Energi will build a liquefaction facility for biomethane at the Port of Gothenburg, which will be connected to the West Sweden gas grid. With the facility in place, a new opportunity will be created for biomethane producers connected to the gas network to reach the maritime market.

“Once the liquefaction plant is completed, we will have a solid solution in place at the Port of Gothenburg. This is a strategic step towards our goal of scaling up and offering competitive liquefied biomethane to the shipping sector, thereby taking a leading position in this segment,” said Ted Gustavsson, Head of Value Chain at St1 Biokraft.
