Analysis of an Ammonia/Ammonium Nitrate Fuel's Thermal Decomposition By Mass Spectrometry and Thermogravimetric Analysis

Bar Mosevitzky Gennady E. Shter Gideon S. Grader

Research on renewable synthetic fuels has become a hot-topic in recent years. This is due to the long-term energy storage capabilities of chemical bonds and their potential compatibility with current energy infrastructure. Specifically, nitrogen-based fuels offer a carbon-free solution to wide scale implementation of renewable energies. Therefore, the inherent chemistry involved in the utilization of these fuels for stationary and mobile power generation is of prime interest. Unlike ammonium nitrate, ammonia suffers from unstable combustion characteristics. Therefore, adding ammonium nitrate to ammonia combustion may stabilize the process. However, while ammonia’s gas-phase reaction mechanism is well studied, ammonium nitrate’s is poorly…

Ignition of an Aqueous Ammonia / Ammonium Nitrate Fuel

Bar Mosevitzky Gennady E. Shter Gideon S. Grader

To achieve a truly renewable energy market, the intermittent power generation of sources such as solar and wind must be overcome. Renewable ammonia can be synthesized using these sources to be used as a long-term energy storage medium. For this reason, the use of ammonia as a synthetic fuel has garnered significant attention in recent years. Aqueous AAN (ammonia/ammonium nitrate) is a carbon-free ammonia based monofuel suitable for energy storage applications. This fuel is safe to store and transport, and its combustion products consist mainly of water and nitrogen. Effective use of this fuel requires an in-depth understanding of the…

Effect of Water on the Auto-Ignition of a Non-Carbon Nitrogen-Based Monofuel

Bar Mosevitzky Rotem Azoulay Lilach Naamat Gennady E. Shter Gideon S. Grader

The fluctuating nature of renewable energy sources is becoming a limiting factor in their widespread utilization. Energy storage solutions must be developed to overcome this issue. Chemical fuels are considered to be a promising solution to this problem. We are studying the implementation of nitrogen-based fuels for this purpose. An aqueous solution of ammonium nitrate and ammonium hydroxide (AAN) is suggested as a carbon-free nitrogen-based synthetic monofuel. This solution may serve as a renewable nitrogen-based synthetic hydrogen carrier since it is safe to store, transport and utilize. Since ammonium hydroxide (AH) and ammonium nitrate (AN) act as reducer and net…

Nitrogen-Based Fuels: Renewable Hydrogen Carriers

Gideon S. Grader Michael Epstein Ayillath Deepa Oren Elishav Gennady E. Shter Bar Mosevitzky

Renewable energy sources such as solar and wind suffer from an intermittent power output, making energy storage a key element in future energy infrastructure. Fuels offer both high energy densities and efficient transport compared to other energy storage alternatives. One energy storage solution is water electrolysis. However, the generated hydrogen is incompatible with the global fuel infrastructure, inhibiting its implementation as an energy vector. Storing hydrogen on carrier atoms provides a safe and convenient way to utilize and transport renewable energies. While carbon–based fuels are commonly suggested, using nitrogen as a hydrogen carrier can potentially offer a superior option. In…
