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.

Global emissions implications from co-combusting ammonia in coal fired power stations: An analysis of the Japan-Australia supply chain

This study considers the emissions implications of co-combusting imported ammonia in coal-fired power stations. The study adopts a supply chain approach, estimating the emissions reduction potential of 20% ammonia co-combustion in coal-fired power stations in the country of use (Japan), and the emissions associated with ammonia production in the country of origin (Australia). The results show co-combustion of ammonia produced with SMR-HB provides no net benefit for the combined country emissions, as ammonia production related greenhouse emissions in Australia are equivalent to the emission reductions in Japan. In contrast, co-firing ammonia produced from fully renewable sources reduces emissions in the…

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.

Trailing ammonia-coal co-firing in India

Adani Power and two Japanese organisations - IHI Corporation and Kowa - have signed a new MoU to conduct a feasibility study into 20% ammonia-coal co-firing at the Mundra power plant in Gujarat, India. The trio will also investigate increasing this co-firing percentage all the way up to 100% ammonia fuel (“mono-firing”). The new MoU contributes to a national-level partnership announced last week - the "India-Japan Clean Energy Partnership (CEP)".

Building hydrogen and ammonia value chains in Indonesia

Indonesia’s state-owned fertiliser manufacturer will join forces with Mitsubishi Corporation to explore the feasibility of hydrogen & ammonia supply chains in the country: both renewable and CCUS-based. The new partnership aims to reduce coal utilisation at existing thermal power plants via co-firing with ammonia, helping Indonesia to meet its emissions reduction targets.

New benchmark for coal co-firing reported in China

The South China Morning Post reports that China Energy Investment Corporation has successfully demonstrated co-firing 35% ammonia with coal at a power generation unit in Shandong Province. Further technical details emerged from additional Chinese media outlets, including that the pilot test occurred in a 40 MW coal boiler at the Huaneng Yantai coal power plant, and that NOx emissions were reportedly lower than burning pure coal fuel.

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.

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.
