Ammonia as a liquid for the future of aviation
Presentation

Zero-emission aviation initiatives have mainly focused on using hydrogen or drop-in biofuels and sustainable aviation fuels (SAF) to replace fossil-based jet fuels to achieve near-term reductions in carbon emissions with minimal impacts on the global aircraft fleet and supporting infrastructure. Despite significant advances in the production of such fuels, scaling up manufacturing capability to be cost-competitive remains a challenge. This paper discusses ammonia as a carrier of green hydrogen for aviation, with near-zero emission. Ammonia is proposed as both a carrier of hydrogen as fuel and to provide cooling for compressor intercooling and cooled cooling air for core efficiency improvement,…

Ammonia cracker: design and safety considerations
Presentation

Ammonia cracking is an endothermic reaction with characteristics similar to those of steam methane reforming. As a result, large scale ammonia crackers are likely to more than a passing similarity to the steam-methane reformers which are currently used to convert natural gas to hydrogen. When transferring technology from one industry to another the challenge is to distinguish between know-how which benefits the new application, and which should therefore be applied; and know-how which is detrimental to the new application and therefore needs to be either unlearnt or relearnt. The presentation will cover the choices facing the designer of a large-scale…

Exhaust gas treatment catalysts for ammonia-fueled engines
Presentation

Ammonia is expected to be a promising zero-emission fuel because it does not emit CO2 during combustion. However, the exhaust gas from the actual ammonia-fueled engines contains unburned ammonia, nitrogen oxides (NOx), and nitrous oxide (N2O), and there is a need to develop technologies to remove these harmful substances. Unburned ammonia can be removed by a catalytic combustion method using a conventional oxidation catalyst, but NOx and N2O are simultaneously generated as byproducts. Therefore, Nikki-Universal has developed a new catalyst that can remove ammonia at high efficiency while reducing the generation of NOx and N2O. We have also developed a…

Natural gas based, ultra-low carbon ammonia without fluegas scrubbing
Presentation

Reducing the carbon footprint of ammonia is urgent more than ever, and requires new technology innovations to achieve this goal, while keeping these plants competitive and viable. In this session, we will review latest proposed technologies from thyssenkrupp Uhde to achieve ultra-low carbon emissions by implementing a new process flowsheet that replaces the common primary reforming approach and eliminates the need of a fluegas scrubbing system. We will also review the advantages of the new proposed technologies in terms of capex and management of risk associated with new technology implementation.

Making ammonia blue - the easy way
Presentation

Production of low-carbon “blue” ammonia requires the addition of a carbon capture & storage (CCS) solution to the ammonia value chain. With the prevalence of geologic storage immediately below many US ammonia production facilities, onsite co-location of CCS facilities provides a number of attractive benefits to producers looking to make their ammonia low-carbon. Onsite CCS is a proven, ready-to-execute solution (the only two existing CCS projects in the U.S. today are co-located with emitting facilities) that delivers a lower cost, lower complexity decarbonization pathway for ammonia production, while simultaneously capturing the benefits of “outsourcing” CO2 disposal.

Low-carbon ammonia at LSB Industries
Presentation

LSB Industries is the fifth largest ammonia producer in the US and operates three manufacturing facilities in Oklahoma, Arkansas, and Alabama. This year, the company announced its sustainability priorities and two major projects designed to reduce the carbon intensity of its ammonia production. The projects will reduce the companies carbon footprint by over 25% and consist of the construction of a carbon capture and sequestration facility to permanently sequester 450k metric tons of CO2 annually and the retrofitting of an ammonia plant to handle clean hydrogen from eletrolysis which will turn ~15% of the plant production into zero-carbon ammonia. Details…

Electrifying ammonia production using four metric tons per day (4 MTPD) Independent Ammonia Making Machine (IAMM™) units
Presentation

Anhydrous ammonia price reached a historical high up to $1,700/short ton NH3 in mid-2022. In the meantime, Europe has shut down ammonia production at a capacity of over 3 million tonnes per year due to limited supply and the high cost of natural gas. AmmPower pioneers the development of the Independent Ammonia Making Machine (IAMM™) units, which allow decentralized production of green ammonia at a capacity of 4 MTPD using renewable electricity. The compact and modular IAMM™ units have multiple configurations, including electrolyzer and ammonia storage options. AmmPower delivers IAMM™ units at a low lump sum cost and a short…

Advanced technologies powering green ammonia R&D
Presentation

Fujitsu has been working to find innovative solutions within the energy transition that would benefit from the company’s extensive experience in high performance computing (HPC), AI, quantum computation, materials science, molecular dynamics, and nanoscale materials development. Fujitsu has identified green ammonia as a field with technical challenges that could be addressed by the company’s unique capabilities and has partnered with an Icelandic start-up, Atmonia, to leverage HPC and AI technology in advancing electrochemical ammonia synthesis technology. This talk will provide an overview of the role of advanced technologies to speed up green ammonia R&D.
