The <i>NH<sub>3</sub> Kraken</i>: Amogy’s ammonia-powered tugboat
Article

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.

Siemens Energy begins work on commercial cracker prototype
Article

Siemens Energy, Fortescue Future Industries and GeoPura are developing a £3.5 million ammonia cracker prototype in Newcastle, UK. The prototype will deliver 200 kg of high-purity, PEM-suitable hydrogen fuel per day, and will be based on Fortescue’s “Metal Membrane Technology” (MMT) purification process. GeoPura will act as offtaker for the prototype facility, with the hydrogen to be used as in its Hydrogen Power Unit fuel cell technology.

The Korean New Deal and ammonia energy
Article

South Korea has featured in many Ammonia Energy news updates, but often in a scatter gun fashion that lacked the momentum of ammonia energy announcements coming from the other side of the Korea Strait. Now, South Korea is ready to step out from Japan’s shadow as a clean energy innovator and deployer in its own right. We’re seeing the beginnings of a well-articulated strategy to achieve society-wide decarbonisation in South Korea, with a starring role for clean hydrogen and clean ammonia.

The Ammonia Wrap: commercial turbines, another GW of green ammonia, Viking Energy updates, and
Article

Welcome to the Ammonia Wrap: a summary of all the latest announcements, news items and publications about ammonia energy. This week: commercialised ammonia gas turbines, TDK and GenCell join forces, another GW of green ammonia production, small-scale green ammonia in rural Japan, hydroelectric ammonia in Laos, Viking Energy vessel updates, new partnerships for Haldor Topsoe and "any-fuel" high-temp PEM fuel cells.

More Progress for Automotive-Oriented Direct Ammonia Fuel Cells
Article

Shimshon Gottesfeld’s paper The Direct Ammonia Fuel Cell and a Common Pattern of Electrocatalytic Processes leads with a big number: “A record power density of 450 mW/cm2 has been demonstrated for a direct ammonia fuel cell [DAFC] using an alkaline membrane electrolyte.”  We know it’s big because it’s 80% higher than the 250 mW/cm2 that Gottesfeld’s team had achieved in the fall of 2017 and that Gottesfeld, Adjunct Professor of Chemical Engineering at the University of Delaware, reported at the November 2017 NH3 Energy+ Topical Conference.

Development of a Highly Efficient COx-Free Ammonia Dehydrogenation System for Fuel Cell Applications
Presentation

The shortage of fossil fuels and emission of carbon dioxide to the environment have attracted an interest in discovering renewable energy as the next generation energy source. Owing to its intermittent and unpredictable nature, however, excess renewable energy needs to be stored and reused on demand. In the regard, hydrogen, which possesses a high gravimetric energy density and carbon free combustion process, has been extensively researched as a promising renewable energy carrier. However, the distribution and storage of hydrogen still raise important challenges due to the low volumetric energy density of hydrogen for its wide utilization. Currently, gaseous hydrogen transportation…

Ammonia As a Hydrogen Carrier for PEM Fuel Cells
Presentation

Ammonia (NH3) is easily liquefied by compression at 1 MPa and 25°C, and has highest volumetric hydrogen density of 10.7 kg H2 /100L. It has high gravimetric hydrogen density of 17.8 wt%. The heat of formation of NH3 is about 1/10 of combustion heat of hydrogen. NH3 has advantages as a hydrogen carrier for fuel cell vehicles (FCVs). ISO 14687-2:2012 specifies the quality characteristics of hydrogen fuel. The maximum concentration of NH3 and N2 for the FCVs is 0.1ppm and 100 ppm, respectively. The minimum H2 purity is 99.97%. We need component technologies to produce high-purity hydrogen from ammonia, together…

Ammonia for Fuel Cells: AFC, SOFC, and PEM
Article

In the last 12 months ... IHI Corporation tested its 1 kW ammonia-fueled solid oxide fuel cell (SOFC) in Japan; Project Alkammonia concluded its work on cracked-ammonia-fed alkaline fuel cells (AFC) in the EU; the University of Delaware's project for low-temperature direct ammonia fuel cells (DAFC) continues with funding from the US Department of Energy's ARPA-E; and, in Israel, GenCell launched its commercial 4 kW ammonia-fed AFC with field demonstrations at up to 800 locations across Kenya.
