Siemens Energy begins work on commercial cracker prototype

By on November 18, 2022
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

By on April 15, 2021
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.

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

By , , , and on October 31, 2018
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

By on October 31, 2018
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

By on October 25, 2018
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.

Delivering Clean Hydrogen Fuel from Ammonia Using Metal Membranes

By on November 1, 2017
The use of ammonia (NH3) as a hydrogen vector can potentially enable renewable energy export from Australia to markets in Asia and Europe. With a higher hydrogen density than liquid H2, plus existing production and transport infrastructure, and well-developed safety practices and standards, the financial and regulatory barriers to this industry are lower than for liquid H2 transport. The only significant technical barrier which remains, however, is the efficient utilisation of ammonia fuel at or near the point of use, either directly or through the production of H2. For H2 production from NH3, the purity of the product H2 is…
