Ammonia Safety in End Use Applications

Alex Gupta

In the transition to a low-carbon energy economy, renewable power generation is pivotal, but reliable energy provision requires long-term, sustainable energy storage solutions. Ammonia’s relatively high energy density, existing global infrastructure, and established manufacturing and distribution system make it an attractive alternative energy carrier. However, as new applications emerge, thorough risk assessments and control measures are necessary to minimize health and environmental risks. This work evaluates the safety considerations associated with ammonia as a fuel for end use applications, including industry and transportation. Established practices offer insights, yet novel applications require dedicated safety strategies. Ammonia’s potential hinges on comprehensive risk…

Ammonia fuel for glass production demonstrated in Japan

Julian Atchison September 19, 2023

Asahi Glass Corporation announced it has successfully used 100% ammonia fuel to produce architectural glass over two days of testing at its Yokohama Technical Center, with NOx emissions below environmental thresholds. The news follows successful ammonia co-firing tests to produce cement clinker by Mitsubishi UBE Cement Corporation.

MHI Energy Transition and Ammonia Firing Gas Turbine

Masanori Yuri

MHI Group released the “Carbon Neutrality Declaration by 2040” with the theme of “MISSION NET ZERO” and we are working to develop technologies and businesses towards the goal. In this panel session, MHI’s technology roadmap for CO2 zero power generation is presented first, where ammonia and hydrogen firing GT/GTCC plays an important role. Then technologies development and validation progress for the ammonia firing GT are presented and discussed together with MHI involved Ammonia power generation projects worldwide. Lastly activities of Hydrogen GT development and validation are briefly introduced.

Exhaust gas treatment catalysts for ammonia-fueled engines

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…
