ARPA-E’s “transformative” ammonia synthesis technologies
Article

The US Department of Energy's Advanced Research Project Agency (ARPA-E) is funding projects with a view to commercializing low- and zero-carbon ammonia synthesis technologies. Grigorii Soloveichik, ARPA-E Program Director, described the aims and challenges of his agency's initiative and introduced the technologies currently in development in his keynote presentation at the recent NH3 Fuel Conference, in September 2016.

Australia's Concentrated Solar Fuels Program
Article

Solar ammonia' could be the key to the sustainable energy economies of two nations. During his talk at the 2016 NH3 Fuel Conference, Keith Lovegrove, Head of Solar Thermal at IT Power Group in Australia, said that Japan and Australia have the opportunity to move their trade in energy onto a climate-friendly foundation. This would involve development of Australia's solar resources in a way that helps Japan ramp up its Strategy for Hydrogen & Fuel Cells in the coming decades.

H2 @ Scale: US DOE's Request for Information
Article

The ammonia energy community has an opportunity to provide input to the United States Department of Energy (USDOE) as it defines priority areas for its new "H2 @ Scale" initiative. The USDOE posted a Request for Information (RFI) on September 9. Interested parties are invited to comment on all aspects of the H2 @ Scale concept. The deadline for comments is November 4. A link to the RFI is provided below.

Decentralised ammonia production in the Netherlands
Presentation

Our presentation will summarize the results of two government funded research projects Proton carried out over the last year. The presentation will give an overview of the Dutch power and chemicals (ammonia) markets. We will start by including a brief history of both markets, current trends and foreseen problems. We propose that electrification of the chemical industry will solve the anticipated problems.

Ammonia for Green Energy Storage and Beyond
Presentation

Siemens is participating in an all electric ammonia synthesis and energy storage system demonstration programme at Rutherford Appleton Laboratory, near Oxford. The demonstrator, which will run until December 2017, is supported by Innovate UK. Collaborators include the University of Oxford, Cardiff University and the Science & Technology Facilities Council.

Presentation

Ceramatec Inc., in partnership with its partners, will develop a lower temperature and higher efficiency membrane process to synthesize ammonia for energy storage. Ammonia (NH3) is carbon-free, has a high energy density (>4 kW/l), which enables many hours of energy storage from large renewable power projects in small areas, and can be back converted to electricity using turbines or fuel cells at high efficiency. Ammonia synthesis is currently carried out in very large Haber-Bosch plants, mostly fueled from natural gas. The current large-scale Haber-Bosch (H-B) technology needs to run at constant inputs of energy and reactants. Moreover, ammonia is an…

Ammonia Storage Materials Using Metal Halides and Borohydrides
Presentation

Ammonia (NH3) is easily liquefied by compression at 1 MPa and 25 °C, and has a highest volumetric hydrogen density of 10.7 kg H2 /100L in hydrogen carriers. The volumetric hydrogen density is above 1.5 times of liquid hydrogen at 0.1 MPa and -253 °C. The vapor pressure of liquid NH3 is similar to propane. Moreover it has a high gravimetric hydrogen density of 17.8 mass%. NH3 is burnable substance and has a side as an energy carrier which is different from other hydrogen carriers. The heat of formation of NH3 is 30.6 kJ/molH2. The value is about 1/10 of…

Presentation

Ammonia has attracted interest as a promising alternative fuel for internal combustion engines due to the fact that ammonia does not release carbon dioxide during combustion.[1] Storing ammonia in the form of metal ammines is the most notable way to overcome the challenges that are related to the use of NH3 in liquid form, namely the toxicity and corrosive nature of ammonia.[2] Ammine complexes of light transition metal halides (such as Co, Ni) are very promising candidates because they exhibit high ammonia contents and they are relatively stable at room temperature. The CoX2 system is an interesting candidate, especially cobalt…

Thermochemical energy storage with ammonia and implications for ammonia as a fuel
Presentation

This seminar presents recent advances in ammonia-based thermochemical energy storage1 (TCES), supported by an award from the US Department of Energy SunShot program. The goal of SunShot is to “reduce the total installed cost of solar energy systems to $.06 per kWh by 2020.” Within the arena of concentrating solar thermal power, Sunshot has established goals for each subsytem, including reducing the cost of the energy storage subsystem to $15 per kWht of stored energy and enabling working fluid temperatures greater than 600°C, consistent with advanced, high performance power blocks. Schematic of an NH3-based thermochemical energy storage system. In ammonia-based…
