Proton-Based Solid Acid for Ammonia Removal

Masakuni Yamaguchi Tomoyuki Ichikawa Hikaru Miyaoka Keita Nakajima Tengfei Zhang Hiroki Miyaoka Yoshitsugu Kojima

Large amount of water is a NH3 absorbent in the plant facilities for emergency. NH3 and NH4+ coexist in ammonia water. For example, potential of hydrogen (pH) is 11 in 2500 ppm ammonia water and the ratio of NH3 and NH4+ are 98% and 2%, respectively. The aqueous solution releases NH3 due to the high equilibrium vapor pressure, resulting in increase of the negative effects on the environment. Therefore, in order to reduce ammonia released to the atmosphere, sulfuric acid is added in the aqueous solution. In this case, ammonium sulfate is formed and dissolves in the water. Therefore complicated…

Ammonia = Hydrogen 2.0 Conference: panel discussion recap

John Mott September 12, 2019

The Ammonia Energy Association Australia’s Ammonia = Hydrogen 2.0 Conference took place on 22-23 August 2019 in Melbourne, Australia. It attracted 115 attendees from industry, government, and research institutions. This is the first of two articles about the event; this article recaps the interactive panel sessions and the second article will highlight selected presentations. The panel discussions were placed at the end of the program so that important themes from the presentations could be highlighted and integrated. These themes included: 1) Building an energy export industry using green ammonia; 2) Green ammonia as a maritime bunker fuel; and 3) Green ammonia as grid scale energy storage – a battery to the nation.

ARPA-E request for information: Pre‐pilot and pilot projects to scale, mature, and advance technologies

Trevor Brown April 17, 2019

ANNOUNCEMENT: The US Department of Energy's Advanced Research Projects Agency (ARPA-E) has published a Request For Information (RFI) focused on supporting scale-up demonstrations of ARPA-E technologies. Unlike normal ARPA-E funding agreements, which typically provide 5%-20% of the financing for bench-scale projects within laboratories, this RFI is geared towards industrial pilot projects, for which ARPA-E would provide "at least 50% cost share."

EPRI Releases Ammonia Energy Report

Stephen H. Crolius March 07, 2019

Last month the Electric Power Research Institute (EPRI) released Renewable Ammonia Generation, Transport, and Utilization in the Transportation Sector, the organization’s first public treatment of ammonia energy. The report is positioned as a communique from the cutting edge – a “Technology Insights Brief” from EPRI’s “Innovation Scouts” – and, bracingly, manages to be both brief and comprehensive. Within its format, it does an excellent job of conveying the positive case for ammonia energy and the R&D that will allow it to reach its potential.

Hydrogen and Ammonia Discussed in Australian Energy Storage Report

Stephen H. Crolius January 18, 2019

The Australian report Comparison of dispatchable renewable electricity options does the very useful service of quantifying the energy storage landscape in dollars and cents. It reaches many interesting conclusions, not the least of which is that hydrogen, and by explicit extension, ammonia, is the key option for long-cycle storage. And while the study’s focus is Australia, “with costs in AUD and based on Australian conditions,” its lead author says that “much of the information and many of its findings are expected to hold independent of jurisdiction.”

Functionalized Ordered Mesoporous Silica Composites As Potential Ammonia Storage Materials

Zhu Ming Pan Xingxiang Mei Hua

Ammonia may provide an alternative energy supplier for its strong capability as hydrogen carrier. However, it is a problem that how to storage this kind of chemical at relatively high temperature, for example 300°C in fuel cell. In this work, a composite material based on metal halides and ordered mesoporous silica framework is developed and used to target ammonia at relatively high temperature. The silica framework is fabricated via evaporation induced self-assembly method and has tunable mesoporous structure with addition of hexadecyl trimethyl ammonium bromide (CTAB). Several metal salts at various concentrations are added to the mesoporous framework via wetness…

Power-to-Ammonia-to-Power (P2A2P) for Local Electricity Storage in 2025

Kevin Rouwenhorst Louis van der Ham Guido Mul Sascha Kersten

A carbon-free, circular economy is required to decrease greenhouse gas emissions. A commonly named alternative to the carbon-based economy is the hydrogen economy. However, storing and transporting hydrogen is difficult. Therefore, the ammonia economy is proposed. Ammonia (NH3) is a carbon-free hydrogen carrier, which can mediate the hydrogen economy. Especially for long-term storage (above 1 day), ammonia is more economically stored than hydrogen. Transportation costs are greatly reduced by adopting a decentralized energy economy. Furthermore, political-economic factors influence energy prices less in a decentralized energy economy. With small-scale ammonia production gaining momentum, business models for the decentralized ammonia economy are…

Ammonia as a Grid-Supporting Energy Storage Solution

Stephen H. Crolius October 11, 2018

In the last 12 months ... We have seen repeated enunciations of a compelling logic chain: electricity generated by wind-based and photovoltaic systems is manifesting ever-more competitive economics; the greater the share of electricity generated by intermittently active resources, the greater will be the need for complementary energy storage systems; chemical forms of “X” in the power-to-X (P2X) stored-electricity construct will surely have a role to play in long-term, large-scale energy storage; ammonia may be the most advantageous chemical for such storage.

Green ammonia demonstration plants now operational, in Oxford and Fukushima

Trevor Brown June 29, 2018

Two new pilot projects for producing "green ammonia" from renewable electricity are now up and running and successfully producing ammonia. In April 2018, the Ammonia Manufacturing Pilot Plant for Renewable Energy started up at the Fukushima Renewable Energy Institute - AIST (FREA) in Japan. Earlier this week, Siemens launched operations at its Green Ammonia Demonstrator, at the Rutherford Appleton Laboratory outside Oxford in the UK. The commercial product coming out of these plants is not ammonia, however, it is knowledge. While both the FREA and Siemens plants are of similar scale, with respective ammonia capacities of 20 and 30 kg per day, they have very different objectives. At FREA, the pilot project supports catalyst development with the goal of enabling efficient low-pressure, low-temperature ammonia synthesis. At Siemens, the pilot will provide insights into the business case for ammonia as a market-flexible energy storage vector.
