Ammonia combustion analysis: powertrains, turbines & power generation

This week we explore four updates in ammonia combustion R&D:

1. A team from the University of Cambridge has shown merchant vessels are the strongest candidates for conversion to run on ammonia powertrains, with cargo capacity losses of 4-9% able to be feasibly offset by operators.

2. Researchers at the University of Minnesota have successfully tested a thermochemical recuperation (TCR) reactor to improve the efficiency of a dual-fuel, diesel-ammonia compression ignition engine by minimising ammonia slip.

3. A global team led by Cardiff University researchers has revealed some of the inner workings of ammonia combustion in gas turbine flames.

4. A global team has produced a cradle-to-gate environmental assessment for ammonia production and ammonia-based electricity generation, suggesting that renewable and nuclear ammonia have a significant role to play in decarbonising the power sector.


4.4 million tonnes per year renewable ammonia in Chile

Total Eren will lead development of the H2 Magallanes project in southern Chile. Up to 10 GW of onshore wind capacity will power 8 GW of electrolysers, a desalination plant, an ammonia production plant and port facilities to export the product to local and global markets. At full capacity, 4.4 million tonnes of renewable ammonia will be produced every year. Although H2 Magallanes is still in the pre-feasability stage, it will be launched in 2025, with the aim to begin hydrogen electrolysis in 2027.


How to reduce the LCoA of green NH3 with hybrid CSP-PV plants

The gNH3 production requires a large amount of renewable energy, where the LCoA is strongly affected by the LCoE. If it is considered only a solar solution, the low Photovoltaic (PV) technology cost can achieve competitive gH2 cost. However, the industrial NH3 plant would require power stability in a 24/7 profile, and a storage solution must be included. In this case, the Concentrating Solar Power (CSP) presents an unique and promising advantage with its dispatchability to fulfill this necessity. Therefore, a hybrid CSP+PV solution can give the best cost solution power mix for the green ammonia industry.


Renewable ammonia for grid-scale sustainable energy: Sector coupling for economic competitiveness

Ammonia produced from renewably sourced electrolytic hydrogen has considerable promise as a seasonal energy storage medium to enable high renewable penetration in the electrical power generation mix. Long duration energy storage via ammonia is significantly less expensive than using hydrogen or batteries [1,2]. Renewable ammonia can also be used as in its traditional application as a fertilizer to reduce agricultural carbon intensity. These multiple renewable ammonia use cases give rise to opportunities for sector coupling [3]. For example, an electric utility could deploy ammonia for energy storage while also pursuing additional ammonia production for sale in local agriculture markets. This…


Starfire Energy’s Rapid Ramp modular ammonia plant development status and trajectory

Starfire Energy has transformed from a grant-funded company to an investment-funded company. We are scaling up our Rapid Ramp ammonia production technology to provide renewable, flexible, modular ammonia fuel plants specifically designed to seamlessly integrate with naturally varying renewable power. We will provide an update on the status of our prototype modular Rapid Ramp pilot plant. We will also discuss the development path for mass produced modular plants and illustrate how they will provide the means to make affordable carbon-free NH3 fuel at a broad range of plant sizes and help drive ammonia fuel use to “fuel relevance” and onward…


Stami Green Ammonia to play a key role in decarbonizing the fertilizer industry

Stamicarbon green ammonia technology is based on the proven Haber-Bosh process and a perfect match for Power to X small and medium size project. It unique operational conditions and lean process design lead to a compact plant configuration with a minimum foot print requirement and thus a very competitive Capex when compared to other technologies. Moreover, the relatively high operating pressure makes it possible to obtain a high conversion per path using a minimum volume of catalyst. Maire Tecnimont group is applying Stami Green Ammonia technology in two green feasibility study projects, Greenfield Nitrogen located in the heart of the…


Next Generation Technology Integration Platform for Low- and Zero-Carbon Ammonia Production and Utilization

RTI International and its partners are developing a Technology Integration Platform (TIP) to demonstrate next-generation technologies for ammonia (NH3) production and utilization in a modular testbed as part of U.S. Department of Energy ARPA-E’s REFUEL+IT program. The objective of this effort will be to demonstrate the use of NH3 for long duration energy storage, as a fuel, and a hydrogen (H2) carrier.  The TIP, which will be housed at the University of Minnesota West Central Research and Outreach Center’s operational hybrid wind and solar test site, will integrate several breakthrough technologies developed in the REFUEL program to demonstrate an advanced…


Renewable ammonia in Sweden

Grupo Fertiberia will work with the local government of Norbotten Region, Sweden to develop of a EUR 1 billion green ammonia & fertiliser plant. Powered by a mixture of wind and hydropower, Project "Green Wolverine" will feature 600 MW of electrolysers and produce 500,000 tonnes per year of carbon-free ammonia.


New IRENA report: Decarbonising shipping by 2050

IRENA's new report explores the available options and actions needed en route to a decarbonised global shipping sector by 2050. A pivotal role is forecast for renewable ammonia, with 183 million tonnes per year (the current volume of annual global ammonia production) to be required by 2050 for maritime fuel.
