Development of dense membranes for high-density hydrogen production from ammonia catalytic decomposition (cracking) for PEM fuel cells power in Long-haul Passenger Aircraft Transportation

Gobina E., Robert Gordon University, UK

Aviation is a major greenhouse gas contributor responsible for around 3.2% of global CO2 emissions to the atmosphere. That corresponds to over than 1 billion metric tons of carbon (A metric ton is a little [...]

Low-Pressure Electrolytic Ammonia Production for Ammonia-Based Energy Storage

Thakare J., Masud J., Aulich T., University of North Dakota, US

The Energy & Environmental Research Center (EERC) is developing a low-pressure 1-step electrolytic ammonia (1-SEA) process that would enable ammonia-based energy storage technology (NH3-BEST) in combination with a direct ammonia fuel cell to enable electricity [...]

Renewables-source Energy Storage for < $1.00 / kWh Capex as Hydrogen and Ammonia C-free Fuel Systems

Leighty B., The Leighty Foundation, US

Electricity systems will be inadequate to humanity's urgent task of rebuilding its largest industry -- energy -- from ~85% fossil today to 100% renewable sources by Year 2100. To supply all energy, from all sources [...]

Ammonia Decomposition on Carbon Supported Cobalt Catalyst

Zhang H., Alhamed Y.A., Petrov L., Kojima Y., King Abdulaziz University, SA

Liquid ammonia has both high energy density and high hydrogen storage capacity which makes it suitable for on-board generation of COx free hydrogen by catalytic ammonia decomposition (AD). Cheap catalysts based on cobalt were considered [...]

Properties of nonpremixed ammonia-substituted hydrogen-air flames

Joo J.M., Um D.H., Kwon O.C., Sungkyunkwan University, KR

The effects of ammonia (NH3) substitution on the extinction and nitrogen oxide (NOx) emissions of nonpremixed hydrogen (H2)-air flames at normal temperature and pressure were experimentally studied to evaluate the potential of partial NH3 substitution [...]

Joo J.M., Um D.H., Kwon O.C., Sungkyunkwan University, KR

The effects of ammonia (NH3) substitution on the extinction and nitrogen oxide (NOx) emissions of nonpremixed hydrogen (H2)-air flames at normal temperature and pressure were experimentally studied to evaluate the potential of partial NH3 substitution [...]

Scalable Single Walled Carbon Nanotube Separation: from Process to Product

Fogden S., Kim K.C., Ma C., McFarlane G., Linde Electronics, US

The extraordinary electronic and optical properties of single walled carbon nanotubes (SWNTs) are determined by their structure; SWNTs are1 either metallic or semiconducting depending on their diameter and chirality . Many valuable applications in, for [...]

Propagation and Emissions of Ammonia-substituted Hydrogen/Air Flames

Lee J-H., Lee S.I., Lee J-H., Lee S.I., Kwon O.C., Sungkyunkwan University, KR

In order to evaluate the potential of partial ammonia (NH3) substitution to improve the safety of hydrogen (H2) use in general and the performance of internal combustion engines in particular, the propagation, development of surface [...]
