Ammonia power solutions firm Amogy Inc. on Monday (6 March) announced its plans to present its ammonia-powered, zero-emission tugboat in late 2023. 

The firm said getting the first ammonia-powered vessel on the water signals a huge milestone in the journey to zero-emissions shipping, as ammonia is predicted to become the leading bunker fuel source for the world’s giant cargo ships by 2050.

Amogy is currently retrofitting a tugboat that was originally built in 1957, that uses diesel generators and electric motors, with its ammonia-to-power system. It will be outfitted with a 1-megawatt version of the unique system, three times larger than what has been field-tested on Amogy’s ammonia-fuelled semi truck earlier this year. Amogy’s ammonia-to-power technology feeds liquid ammonia through its cracking modules integrated into a hybrid fuel cell system, which powers the electric motors for zero-carbon shipping.

Seonghoon Woo, CEO of Amogy, said:  “We’re incredibly proud of unveiling the first ammonia-powered vessel later this year — especially because of the hope, promise and anticipation that ammonia has built as a zero-emission fuel in the heavy transportation industry — specifically in regards to maritime shipping.” 

“This is the first milestone of many you will see from Amogy in accelerating the accessibility and scalability of clean energy in the global maritime industry. With successful demonstrations of our ammonia-powered drone, tractor and semi-truck under our belts, we look forward to presenting the first ammonia-powered ship in 2023, with a target to fully  commercialize in 2024.”

Yara Clean Ammonia (YCA), one of the world’s largest ammonia producers, and the largest trader and shipper of ammonia around the world, will be providing green ammonia for the demonstration. 

Magnus Ankarstrand, President of YCA, said: “We are excited to be a part of Amogy’s tugboat project and to deliver green ammonia as a fuel for the world’s first vessel powered by ammonia. Yara Clean Ammonia plans to launch the world’s first Ammonia Bunker Network in Scandinavia, which is expected to expand YCA’s capacity to produce and ship ammonia globally.”

Other partners that are collaborating to bring the first ammonia-powered ship to life include Seam, Amogy’s electrical systems integrator, C-Job Naval Architects, the independent ship design company integrating the ammonia system, and Feeney Shipyard, from whom Amogy sourced the tugboat, who will lead retrofitting construction, engine removal and more under supervision of C-Job Naval Architects.  Additionally, Amogy is working with Unique Technical Solutions (UTS), its electrical and systems integrator from prior demonstrations, for the electrical and systems work involved in scaling up the powerpack for pre-commercial use.

Amogy has developed a proprietary ammonia-to-power technology that converts ammonia to electric power effectively and efficiently. Amogy said it has a deep commitment to safety and compliance, working with the United States Coast Guard and partnering with classification society DNV to ensure close alignment with all maritime safety standards. 

“DNV has been working with Amogy since December 2021, focusing on the safety aspects of the development of their ammonia system,” DNV’s Senior Consultant in Maritime Environmental Technology, Hans-Christian Wintervoll, said. 

“A high-level feasibility study was executed in early 2022, and Amogy has shown great momentum in development from that point, through the HAZID workshop in June the same year, to the HAZOP workshop in January this year. DNV is pleased to contribute to their continued success.”

To date, Amogy has raised USD 70 million in funding from strategic investors such as Amazon, Saudi Aramco, SK Innovation, AP Ventures and DCVC. 

Amogy said it intends to sail the tugboat later in 2023 in upstate New York, pending further safety testing and regulatory discussions.

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.
