The NH3 Kraken: Amogy’s ammonia-powered tugboat

As part of our Maritime Ammonia Insights series, we explore progress onboard the NH3 Kraken, Amogy’s ammonia-powered tug being developed in New York state. We heard updates on vessel retrofits, design points, project partners, the ongoing relationship with the US Coast Guard, HAZOP assessments, regulatory work and the remaining challenges before the tug hits the water for operational trials. Amogy’s Abigail Jablanksky and Chief Safety Solutions’ Herbert Fowlkes joined Conor Furstenberg Stott in conversation.

Ammonia-to-Power to decarbonize heavy industries

Amogy aims to enable the decarbonization of the hard-to-abate sectors, such as shipping and power generation, with its emission-free ammonia-to-power solution. Amogy has developed a compact, high-efficiency ammonia cracker to crack ammonia into hydrogen, where the produced hydrogen is subsequently used to generate power through a fuel cell. This proprietary design leverages the superior physical characteristics of liquid ammonia with the performance advantages of matured hydrogen fuel cell technology. To date, Amogy’s ammonia-to-power system has been demonstrated with success in a 5 kW drone, 100 kW tractor, and 300 kW semi truck, and the Amogy team is working on retrofitting…

Scene-setting for ammonia in the marine industry: propulsion systems, FPSOs & jettyless tech

As the maritime industry gears towards the use of more sustainable fuels, Denmark-based cargo pump supplier Svanehoj reports increased orders for ammonia-capable equipment to be used on LPG tankers. Navantia and H2SITE will combine their expertise in shipbuilding and ammonia cracking to create hydrogen-based propulsion systems. Thyssenkrupp Uhde’s ammonia technology will be used in SwitcH2’s floating ammonia production vessels to harness offshore wind energy. And Iverson eFuels will use ECOnnects’ jettyless gas transfer technology at its 200,000 tonnes per year ammonia production facility in Norway.

Renewable ammonia to support cotton farming in Australia

New Zealand-based Hiringa Energy and Australian group Sundown Pastoral will develop the Good Earth Green Hydrogen and Ammonia Project (GEGHA), which will produce ammonia-based fertiliser & hydrogen for fuel cells to support cotton farming near Moree, New South Wales. The partners are already looking to expand to multiple production projects in the area.

Ammonia cracking technologies gather traction across Europe

In cracking technology updates this week:

  • Air Liquide’s industrial-scale, ammonia cracking pilot plant at the Port of Antwerp is expected to be operational in 2024.
  • In the UK, AFC Energy has announced a new cracking technology platform.
  • Aramco and Linde Engineering have plans to develop their own ammonia cracking technology based on a new catalyst, with a demonstration plant in northern Germany to follow.
  • And Fraunhofer IMM researchers have developed the compact AMMONPAKTOR cracking reactor system, which will be utilised to feed PEM fuel cells.

Ammonia solutions for the UK construction industry

The UK government will fund a new red diesel replacement project from engine developers MAHLE Powertrain and partners Clean Air Power and the University of Nottingham. The trio will demonstrate decarbonisation of heavy duty engines using ammonia and hydrogen fuel, or a blend of the two. Fortescue Future Industries and Liebherr are also involved in the decarbonisation of the UK construction sector, with agreements on hydrogen fuel supply & engine development signed last October. Fuel cells also enter this mix, with AFC Energy currently rolling out off-grid, ammonia-powered gensets on construction sites in London and Madrid.

AmmoniaDrive

The University of Amsterdam and TU Delft will lead an academic-industry consortium that will determine the feasibility of combining ammonia-fed solid-oxide fuel cells with internal combustion engines for maritime propulsion. The AmmoniaDrive project just received over €2 million in support from the Dutch government, and is the latest in a series of hybrid and fuel cell-based propulsion projects using ammonia as an onboard fuel.
