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.

Japan’s first antioxidant by NYK for biodiesel bunker fuel set to release in August

Nippon Yuka Kogyo (Nippon Yuka), an NYK Group company specialising in chemical R&D as well as the manufacture and sale of chemical products, on Wednesday (21 May) announced the upcoming release of BioxiGuard, the Japan’s first antioxidant specially developed for marine biodiesel, from 10 August.

NYK said compared with conventional petroleum-based fuels, biofuel contains a higher proportion of unsaturated fatty acids, making it more susceptible to oxidative degradation. Once oxidised, the biofuel can produce acidic substances and sludge, adversely affecting vessel fuel efficiency by reducing the fuel’s calorific value.

Developed by Nippon Yuka based on property analyses of the biofuel used in NYK-operated vessels, BioxiGuard is specifically formulated to enhance the oxidation stability of biodiesel. When added to biofuel, BioxiGuard slows the progression of oxidative degradation and helps deter issues such as metal corrosion, strainer blockage, and cleaning-system fouling often triggered by oxidised fuel.

According to laboratory tests conducted by Nippon Yuka researchers, the addition of BioxiGuard at a concentration of 1 part per 500 resulted in an approximate 50% reduction in the rate of biofuel degradation compared to untreated biofuel.

This significant improvement underscores the potential for vessel operators to not only extend the useful life of biofuel on board but also maintain more stable and cost-effective vessel operations.

Höegh Autoliners latest LNG dual-fuel PCTC en route to Shanghai for bunkering

Höegh Autoliners on Tuesday (20 May) said its latest liquefied natural gas (LNG) dual-fuel pure car and truck carrier has departed China Merchants Heavy Industry’s yard, ready to commence its commercial operations.

The 9,100 CEU Höegh Sunrise, currently sailing the seas, is on its way to Shanghai for bunkering before sailing to Japan and then towards Europe.

The PCTC is the fifth in a series of 12 Aurora Class vessels built by the shipyard in China. The first eight Auroras are or will be equipped with engines primed to run on LNG and low-sulphur oil.

These vessels can be converted to run on ammonia later. By 2027, Höegh Autoliners said the four last vessels of the series will be able to run net zero on ammonia directly from the yard when delivered.

Manifold Times previously reported the naming ceremony of Höegh Autoliner’s fourth Aurora Class newbuild, Höegh Sunlight, at Taicang Haitong Auto Terminal.

UECC: Liquefied biomethane bunker fuel to enable compliance surplus under FuelEU

United European Car Carriers (UECC) on Monday (19 May) said bunkering liquefied biomethane (LBM), also known as bio-LNG, will give it a significant compliance surplus under FuelEU that can be monetised through the regulation’s pooling mechanism.

UECC’s Senior Manager of Business Planning & Sustainability, Masanori Nagashima, said bio-LNG is now seen by the company as the key fuel to achieve its target of a 45% reduction in carbon intensity by 2030 versus a 2014 baseline and net zero by 2040 – ahead of the 2050 deadline set by both the IMO and EU.

The marine fuel is being bunkered on UECC’s dual and multi-fuel LNG PCTCs – three of which have battery hybrid capability – under Sail for Change that was launched by UECC last year and currently has participation by automotive giants including Toyota, Ford and JLR.

The company also has on order two multi-fuel LNG battery hybrid newbuild PCTCs due for delivery in 2028 that could be enlisted into the programme.

The overall carbon intensity of the UECC fleet, using the same gCO2e/MJ (grams of CO2 equivalent per megajoule) metric as FuelEU, is calculated at 68 gCO2e/MJ to achieve an interim target of a 25% carbon intensity reduction in 2025, though the company is expected to achieve 57 gCO2e/MJ this year based on its supply plan, according to Nagashima.

This is significantly below the current FuelEU threshold of 89.3 gCO2e/MJ – a 2% reduction from the baseline of 91.16 gCO2e/MJ – and still lower than the threshold of 77.9 gCO2e/MJ from 2035 that is a 14.5% reduction versus the baseline figure.

“The low carbon intensity of our fleet means all of our vessels are expected to gain a C rating or above with the IMO’s Carbon Intensity Indicator (CII)” Nagashima explained.

“It also gives us a significant compliance surplus under FuelEU that can be monetised through the regulation’s pooling mechanism, allowing a great commercial opportunity to offset regulatory costs for customers and eliminate FuelEU surcharges.”

“UECC will continue to accelerate its progress in improving decarbonisation of its fleet by further optimising our fuel mix strategy going forward to incorporate more high-impact fuels as these become viable.”
