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.

Singapore-based Straits Bio-LNG aims to deliver 250,000 mt of bio-LNG bunker fuel per year

Straits Bio-LNG, a privately owned supplier of bio-LNG, is aiming to deliver 250,000 metric tonnes (mt) of bio-LNG per year in Singapore, according to SEA-LNG on Thursday (13 February).

The Singapore-based company, led by SK Tan as CEO, is doing so in response to the growing demand for LNG. LNG bunkering volumes have grown significantly in key bunkering hubs as more LNG-fuelled vessels have entered into operation. 

The Maritime and Port Authority of Singapore (MPA) saw a dramatic four-fold increase in 2024 to almost 340,000 mt, SEA-LNG said in a statement announcing Straits Bio-LNG joining the coalition. 

Headquartered in Singapore, the company boasts a growing team led by SK Tan as CEO.  

Yiyong He, Director at Straits Bio-LNG, said: “We’re firmly convinced in the viability of the LNG pathway to decarbonise the shipping industry. With its very low carbon intensity and improving commerciality, liquified biomethane will be a critical piece of the puzzle for decarbonising the sector.”

“By joining SEA-LNG, we’re proud to be part of a collection of first movers making real strides to make the LNG pathway a tangible reality today.”

Straits Bio-LNG aims to reach its bio-LNG supply goal by using pioneering methods. It is currently in the advanced stage of testing breaking down Empty Fruit Bunch (EFB) through an established biological process with high enzyme concentration in its R&D facility in Malaysia. 

Both Palm Oil Mill Effluent (POME) and EFB are sustainable biomass resources listed in the “List of Materials Eligible for ISCC EU Certification” and are therefore compliant with the European Union’s Renewable Energy Directive (RED).

Peter Keller, chairman of SEA-LNG, added: “The Port of Singapore is the largest global bunkering hub. As seen in our View from the Bridge report, 2024 saw record growth in LNG and liquified biomethane bunkering, but we need more fuel to meet upcoming demand.”

“The use of liquefied biomethane as a marine fuel can reduce GHG emissions by up to 80% compared to marine diesel on a full well-to-wake basis. When produced from the anaerobic digestion of waste materials, such as manure, POME or EFB, methane that would otherwise be released into the atmosphere is captured, resulting in negative emissions of up to -190% compared with diesel."

An independent study by the Maritime Energy and Sustainable Development Centre of Excellence at Nanyang Technical University in Singapore found that pure bio-LNG could cover up to 13% of the total energy demand for shipping fuels in 2050, rising to 63% for a 20% blending ratio. 

SEA-LNG added MPA has firmly established itself as a leader in the LNG pathway, with suppliers such as Straits Bio-LNG reinforcing this position. 

Recently, the port launched an Expression of Interest (EOI) to explore scalable solutions for sea-based LNG reloading to complement the existing onshore LNG bunkering storage and jetty capacities and the supply of e/bio-methane as marine fuel in the Port of Singapore.

“Straits Bio-LNG will play a critical role in furthering the expansion of liquified biomethane at scale to meet the demand and continuing to showcase the LNG pathway as a practical and realistic solution for shipowners to decarbonise their operations, starting today,” it said.

The Ministry of Oceans and Fisheries (MOF) Tuesday (11 February) announced that it has prepared the 2025 Implementation Plan for Environment-Friendly Ship Distribution in accordance with the first Master Plan for Environment-Friendly Ship Development and Distribution (2021-2030).

The government enacted the Act on the Promotion of Development and Distribution of Environment-Friendly Ships in December 2018 to mandate the public sector to build environment-friendly ships and provide the private sector with a legal basis to reduce acquisition taxes and provide subsidies when converting into environment-friendly ships. 

As a result, 199 ships were converted into environment-friendly ships as of last year.

This year, the government, local governments, and public institutions plan to invest approximately KRW 222.3 billion (USD 154 million) to support the building or conversion of 81 environment-friendly ships.

The public sector plans to build a total of 34 environment-friendly vessels, including electric-powered or hybrid ships, to reduce greenhouse gas emissions. Additionally, 15 operating ships will be equipped with diesel particulate filters (DPF) to reduce fine dust emissions.

In the private sector, support will be provided for building 20 ships in keeping with the demand for transitioning to environment-friendly vessels. Financial assistance such as secondary financing will continue to be offered as well for 12 vessels for installing environment-friendly equipment.

Meanwhile, applications for the 2025 First Phase of the Certified Environment-Friendly Vessel Supply Support Project will be accepted from 31  January 31 to 27 March to support the construction of environment-friendly vessels by small and medium-sized coastal shipping companies operating in domestic ports.

Eligible applicants include coastal shipping companies that order certified environment-friendly vessels such as electric-powered or liquefied natural gas (LNG)-fuelled ships. Selected applicants can receive subsidies of up to 30% of the ship's construction cost depending on the certification grade and vessel construction expenses.

“We will make generous investments in small and medium-sized shipping companies to convert into environment-friendly ships, drastically reduce greenhouse gases in the shipping industry, and proactively respond to strengthening international decarbonization regulations,” Minister Kang Do-hyung said.
