Ammonia solutions for the UK construction industry
Article

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
Article

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
Presentation

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
Presentation

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
Presentation

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
Presentation

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…

Ammonia combustion engines: latest research
Article

The journey from the laboratory bench to the shop floor continues apace in 2021, as researchers deepen their understanding of ammonia combustion within engines. The team at Université d’Orléans has published several pieces of research already this year, with interesting results on operating limits, spray characteristics and flame propagation.

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

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.
