Exhaust gas treatment catalysts for ammonia-fueled engines

Issei TsujiTomoo IkomaHiroki OkamotoNobuyuki AoiToshiya NashidaYasushi Fujimura

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…

Economic analysis for hydrogen - ammonia decarbonization of a natural gas plant - a phased approach

Heather JacksonSean OrchukJoseph Beach

This paper summarizes a comprehensive technical and economic analysis of a hydrogen-ammonia upgrade to an existing 42 MW natural gas plant. A phased approach is carefully chosen which deploys low-carbon technology in modules which are palatable by large-scale utility customers. The objective is to minimize capital costs of the conversion while maximizing decarbonization as each phase is deployed. A phased approach delivers optionality to utilities which are often locked into carbon-emitting technologies by protracted investment durations. Phase one details implementation of an on-site thermal pyrolysis system. Existing natural gas infrastructure and plant waste heat are used to provide clean hydrogen.…

Program on combustion of ammonia and ammonia-hydrogen mixtures for power generation

Rob SteeleGanesan Subbaraman

GTI Energy and the Electric Power Research Institute (EPRI) have embarked on fundamental and applied investigations of ammonia as an alternative energy carrier under a joint program known as Low-Carbon Resources Initiative (LCRI). Focus is on applications under turbine operating conditions for both ammonia and ammonia-hydrogen mixtures. Participating teams members include the University of Central Florida (UCF), Georgia Institute of Technology and CRAFT Tech. Experimental, conceptual designs of combustors and computational efforts are underway since late 2021 and results to-date will be presented. The presentation will also include expanded tasks related to in-depth pursuit of the topic made possible through…

MAN Energy Solutions 2 stroke Ammonia engine

Kjeld Aabo

The marine industry is convinced that Ammonia is not only a very strong candidate as a future fuel, but also that Ammonia will be one of the leading future fuels. MAN Energy solutions has worked since 2019 on the development of a two stroke engine burning Ammonia by using the Diesel principle (as used for other fuels such as Methane , Methanol, Ethane and LPG) In this presentation, we will give an update on the engine design, which we will start testing in Copenhagen in Oct. 2022. The first ammonia engine (with final engine design and combustion process) is scheduled…

Ammonia solutions for the UK construction industry

Julian Atchison July 19, 2022

The UK government will fund a new red diesel replacement project from engine developers MAHLE Powertrain and partners Clean Air Power and the University of Nottingham. The trio will demonstrate decarbonisation of heavy duty engines using ammonia and hydrogen fuel, or a blend of the two. Fortescue Future Industries and Liebherr are also involved in the decarbonisation of the UK construction sector, with agreements on hydrogen fuel supply & engine development signed last October. Fuel cells also enter this mix, with AFC Energy currently rolling out off-grid, ammonia-powered gensets on construction sites in London and Madrid.

DoE funding for ammonia energy

Julian Atchison May 26, 2022

As part of a new round of funding announcements, the US Department of Energy will contribute nearly $10 million to three significant ammonia energy initiatives:

  • GTI Energy (a recent rebrand of the Gas Technology Institute) will develop a prototype ammonia-powered gas turbine.
  • Raytheon will develop and demonstrate an ultra-low NOx emitting ammonia combustor module for gas turbines.
  • And 8 Rivers received backing to complete a pre-FEED study for its CCS ammonia project in Evanston, Wyoming.

Starfire Energy's Prometheus ammonia cracking technology

Joseph BeachAnastasiia BalaganskaiaJonathan KintnerTaha Rostamzadeh

The lowest cost way to use ammonia as a fuel is as an intact NH3 molecule. However, its slow flame speed can cause challenges managing flame stability, ammonia slip, and nitrogen oxide formation. Some fuel cells also require hydrogen, rather than ammonia. Ammonia cracking can solve these problems by providing either a NH3 + H2 + N2 blend or, with appropriate processing, pure hydrogen. Starfire Energy’s Prometheus cracking technology is a unique approach that uses an oxide catalyst bonded to a metal foil substrate. It provides excellent opportunities to power the cracking reaction with both waste combustion heat or purpose-generated…
