Direct Ammonia Fuel Cell Utilizing an OH- Ion Conducting Membrane Electrolyte

We describe the techno-economic background and the R&D work scheduled for the ARPA-E project “Direct Ammonia Fuel Cells (DAFCs) for Transportation Applications,” which is about to start under the REFUEL program. The project is led by Shimshon Gottesfeld & Yushan Yan, University of Delaware, Jia Wang & Radoslav Adzic, Brookhaven National Laboratory, Chulsung Bae, Rensselaer Polytechnic Institute, and Bamdad Bahar, Xergy Inc. The multidisciplinary R&D work scheduled will cover the fields of advanced membrane and electrocatalyst development, MEA development and fabrication, and stack engineering. The latter two activities will be supported by work at POCellTech, with Miles Page as lead.…

China and Australia collaborate on ammonia as a clean transport fuel

The University of Western Australia has entered the increasingly competitive field of ammonia energy research in Australia, announcing a collaborative agreement to develop "the world's first practical ammonia-powered vehicle" as well as an "ammonia-based hydrogen production plant." These goals are supported by funding from the R&D arm of Shenhua Group, formerly a coal company but now "China's largest hydrogen producer with a production capacity to power 40 million fuel cell passenger cars."

Renewable Hydrogen in Fukushima and a Bridge to the Future

On August 1, 2017 the Japan Government’s New Energy and Industrial Technology Development Organization (NEDO) announced that it will proceed with funding for the construction of a hydrogen production plant in Namie Township, about ten kilometers from the site of the Fukushima nuclear disaster.  The project’s budget is not mentioned, but the installation is projected to be “the largest scale in the world” -- in other words, a real bridge to the future and not a demonstration project.  The project no doubt has a variety of motivations, not least the symbolic value of a renewable hydrogen plant rising in the shadow of the Fukushima Daiichi nuclear station.  In economic terms, though, it appears to be a dead end.  This is unfortunate because a similarly conceived project based on ammonia could be a true bridge-building step that aligns with leading-edge developments elsewhere in the world.

BOC/Linde Embraces Ammonia-Based Hydrogen Fueling Technology

Dateline Sydney, August 22, 2017.   Industrial gas vendor Linde Group (under its BOC brand) confirms its participation in a previously announced Australian ammonia-energy project.  With the Commonwealth Scientific and Industrial Research Organization (CSIRO) in the lead, the project partners will build and operate a pilot-scale “ammonia-to-hydrogen cracking” facility that showcases CSIRO’s hydrogen purification membrane technology.  BOC/Linde will contribute goods and services valued at AUD$100,000 (USD$80,000) to the AUD$3.4 million project.

The new generation of fuel cells: fast, furious, and flexible

At ARPA-E's recent Energy Innovation Summit in Washington, DC, Program Director Grigorii Soloveichik presented his vision for the future of transportation: hybrid electric vehicles that combine the advantages of both plug-in battery and fuel cell technologies. This "optimal solution" will require a new generation of fuel cell that is "fast, furious, and flexible." Fast, in terms of start-up / shut-down time. Furious, in terms of energy density. And flexible, in terms of fuel choice - specifically sustainable liquid fuels, like ammonia.

A Green Ammonia Economy

Ammonia has a high volumetric hydrogen density of 107.3 kg H2 per cubic meter, because it is easily liquefied by compression below 0.86 MPa at 20° C. The vapor pressure of liquefied ammonia is similar to propane. Moreover it has a high gravimetric hydrogen density of 17.8 mass% compared with the solid state hydrogen storage materials. It is noteworthy that ammonia can be synthesized from hydrogen in large scale manufacturing by Haber–Bosch process at 400-600° C and 20-40 MPa. Therefore, liquid ammonia is one of the most promising methods for storing and transporting hydrogen. CO2 free hydrogen (ammonia) will be…
