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

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

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…


Ammonia combustion for power generation: updates from Korea, Malaysia and Singapore

Joint venture SK Plug Hyverse has agreed to deploy its Korean-manufactured PEM electrolysers overseas, and then supply Korea South-East Power (KOEN) with renewable hydrogen & ammonia imports for co-firing at natural gas and coal power plants. In Malaysia, power utility Tenaga Nasional Bhd, IHI Power Systems and Petronas announced they have successfully conducted 60% ammonia co-combustion trials. And in Singapore, Jurong Port, Mitsubishi Heavy Industries and JERA will conduct a joint study on Jurong Island, where a 60MW, combined-cycle gas turbine will be fueled by 100% ammonia to produce zero-carbon electricity.


Dual-fuel ammonia for power generation in South Korea

Doosan, KEPCO and Samsung will join forces to jointly develop a “dual-fuel green ammonia” power generation model that can be rolled out to 1 GW power plants in South Korea. In the trio, Doosan is charged with the development of ammonia dual-fuel boilers, indicating that coal co-firing is the target of the model rollout. As part of a different agreement, Doosan is also involved in ammonia-hydrogen gas turbine development with POSCO and KEPCO.


DoE funding for ammonia energy

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.


JERA targets 50% ammonia-coal co-firing by 2030

Japanese government funding via NEDO will support four critical ammonia energy projects, including JERA's new plan to demonstrate 50% ammonia-coal co-firing by 2030. Other projects include improved catalysts for ammonia production, low-temperature and low-pressure synthesis pathways, and developing 100% ammonia-fed boilers and gas turbines. In addition, a new cooperation agreement between ASEAN countries will see Japan support other members to adopt their ammonia energy solutions, particularly coal co-firing.


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.


South Korea sets targets for hydrogen & ammonia power generation

South Korea's Ministry of Trade, Industry and Energy (MOTIE) announced ammonia coal co-combustion will be operational in over half the country's coal-fired power generating units by 2030. The government has already set a target of 13.8 - 21.5% of national power generation coming from hydrogen & ammonia-fed gas turbines by 2050 (the 2050 Carbon Neutrality Roadmap was approved in October). To help drive the required commercialisation & technology deployment, MOTIE, KEPCO and other Korean power utilities will collaborate in a ‘Hydrogen and Ammonia Power Generation Demonstration Promotion Group’. In supply news, South Korean oil & gas major GS Energy announced this week is will join ADNOC and Japan-based Mitsui & Co. to develop the million tonne per year blue ammonia project in Al Ruwais, UAE.
