Starfire Energy’s Prometheus ammonia cracking technology

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…

Green Ammonia Opportunities in Utility Resilience/Storage and Logistics

The presentation will describe projects being undertaken in the Western United States utilizing low cost and redundant renewable energy resources to generate green hydrogen that would be converted to green ammonia; that ammonia will be utilized in various ways but will provide a readily available source of energy for use as an energy storage system by utilities (with a focus on municipal utilities) that will use these systems for energy resiliency and storage, as well as industry and consumer facing users such as fleet fueling (as ammonia, hydrogen, and electrical power for EVs), as well as maritime applications.

IHI’s Development of Ammonia Combustions Technologies / Fuel Ammonia and Hydrogen Solutions

IHI, as a pioneer in the development of the ammonia value chain, has been developing fuel ammonia technology for the last decade. Utilizing existing infrastructure that is either already in place or that can be readily modified, fuel ammonia is highly anticipated as a critical resource to reach a carbon-neutral society. In the presentation, IHI will highlight its involvement in the development of combustion technologies of fuel ammonia for power generation.  A specific focus will be placed on the ongoing development and implementation of 20% ammonia co-combustion in existing coal fired power plants.  The presentation will feature the JERA demonstration…

Impact of ammonia as a fuel / co-fuel on NOx emissions

Ammonia is a hydrogen-based, carbon-free energy carrier. It has good energy density (22.5 MJ/kg) and can be liquefied (about 10 bar at 298 K). With the increasing demand to lower the CO2 emissions worldwide, pure ammonia combustion or co-combustion with a conventional fuel is an alternative solution in turbines, gas engines, power plants, furnaces, and cement kilns. The major challenges with the use of ammonia as a fuel are lowered heat flux and increased NOx emissions. These parameters were analyzed in Linde’s lab-scale tests with pure ammonia as well as mixtures of ammonia and natural gas. Tests were conducted with…

Production and utilization of green ammonia: KIER’s current status and future plans

Green ammonia, a carbon-free chemical, has been drawing much attention as a hydrogen carrier and carbon-neutral fuel for trading green hydrogen and building a carbon-neutral society, respectively, because it has higher volumetric hydrogen content and energy density than liquid hydrogen. And the infrastructure for storing and transporting ammonia is already in place. To implement green ammonia into the current energy systems, technologies on low-cost green ammonia production, decomposition, and utilization are essential. This presentation will show the KIER’s current status and perspective on the development of low-cost green ammonia production and utilization.

Cardiff-KAUST-Tohoku Young Researcher Workshop on Ammonia Energy

Organised by a panel of young researchers — and for young researchers — Cardiff University, KAUST and Tohoku University hosted a virtual workshop on ammonia energy. Each group showed their most recent research developments through the two-day event, attracting 50+ participants from the three groups alone. The event included research introductions from the research leaders of each group as well as quizzes, discussion rooms, prizes. Each group selected 6 early career presenters to feature their latest work in the topics of chemistry and microflow reactors, laminar and turbulent flames and applications. Taking advantage of the discussion sessions, this workshop hopes to promote large scale international collaboration and a researcher exchange programme in ammonia energy.
