Economic analysis for hydrogen - ammonia decarbonization of a natural gas plant - a phased approach
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.
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.
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:
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.
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'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.
