Ammonia takes key role in Taiwan’s energy transition strategy

Geofrey Njovu August 30, 2024

We highlight ammonia developments in Taiwan in line with the island nation’s plans to achieve net-zero emissions by 2050:

  • Taiwan’s largest fertiliser manufacturer, Taiwan Fertiliser Company, will collaborate with ammonia industry giants Mitsubishi Heavy Industries and IHI Corporation to develop a low-carbon ammonia supply chain.
  • Taipower, IHI and Sumitomo have an agreement in place to develop a 5% ammonia-coal co-firing demonstration project at Taipower’s Dalin Power Plant by 2030.
  • And ITOCHU and U-Ming Marine Transport’s partnership for the joint ownership and operation of ammonia-fueled ships.

R&D recap: the Journal of Ammonia Energy – volume II

Geofrey Njovu August 13, 2024

Ahead of the international Symposium on Ammonia Energy event next month, we recap R&D presented in the second edition of the Journal on Ammonia Energy:

  • An integrated, indirect ammonia solid-oxide cell featuring a heat exchanger and ammonia cracker was modelled, built and tested by the UK’s Science and Technologies Council (STFC).
  • The techno-economics of the transportation of energy from Orkney, Scotland to Milford Haven, Wales using ammonia as an energy carrier transported by ship may be the most cost-effective option.
  • N2O and NOX conversion in ammonia engine exhausts is limited by the presence of oxygen and water, presenting an optimisation challenge for technology developers.
  • And an academic-industry joint session on ammonia safety highlighted multiple projects currently underway to tackle the risks associated with the use of ammonia in new commercial sectors.

R&D recap: the Journal of Ammonia Energy

Geofrey Njovu August 06, 2024

Ahead of the 3rd Symposium on Ammonia Energy in Shanghai next month, we take the opportunity to highlight select papers and key results from the first two editions, starting with the 2022 Cardiff event:

  • In an ammonia-diesel blending study, Orleans University and WinGD found that minimising the diesel fraction actually led to increased N2O emissions.
  • In a bid to produce an optimal ammonia-hydrogen fuel blend, a University of Birmingham team characterised the ammonia cracking mechanism of a new, transition metal-promoted lithium amide catalyst.
  • A KAUST study of swirl intensity of an ammonia-methane blended fuel finds that increasing the swirl number leads to a more compact flame, reducing NOX emissions.
  • A team from the University of Minnesota found that combustion durations comparable to gasoline were obtained for ammonia-hydrogen fuel blends.
  • And, as part of a joint academic-industry session on safety, it was recommended that a careful, proactive approach is taken towards new ammonia users, likely exposure risk points and deploying maritime ammonia fuel.

Onboard cracking, fuel storage and adhering to emissions standards: highlights from the MariNH3 conference

Geofrey Njovu July 10, 2024

At last month’s MariNH3 conference in Nottingham, a series of keynotes laid out the opportunities and challenges ahead for marine ammonia fuel. Onboard ammonia cracking technologies are moving through testing phases and closer to commercialisation, vessel designers are working through the unique challenges of carrying ammonia fuel onboard, and emissions mitigation technology (in combination with adherence to existing Tier 3 standards) will be necessary to ensure that ammonia-powered vessels are more environmentally-friendly than conventional counterparts.

The 3rd Symposium on Ammonia Energy: Shanghai, Sept 22-26

Agustin Valera-Medina July 08, 2024

Learn more about the 3rd Symposium on Ammonia Energy, to be held in Shanghai from 22-26 September this year. The AEA is a proud supporter of the event, which will showcase the latest R&D in ammonia energy. Hear from a program of global researchers, take part in industry collaboration workshops, and get the chance to explore local R&D in a series of site visits.

Marine ammonia combustion engines under development in the UK

Julian Atchison February 14, 2024

AFC Energy, MAHLE, the University of Nottingham and Clean Air Power have been awarded funding from Innovate UK to demonstrate the feasibility of ammonia combustion engines in the marine sector, based on the integration of AFC Energy’s ammonia cracking technology. The new program builds on a prior R&D program exploring ammonia combustion engines for the off-road construction industry.

GE, IHI progress ammonia gas turbine technology roadmap

Julian Atchison February 06, 2024

GE Vernova and IHI Corporation will proceed to the engineering and testing phase for their ammonia gas turbine roadmap for Asia. Based on their efforts in 2022 to demonstrate a low-N2O combustor for a 2 MW, 100% ammonia-fired turbine, IHI will lead development of a two-stage combustor for larger-scale gas turbine models.

Mazda includes ammonia fuel in future energy roadmap

Julian Atchison January 03, 2024

To power its global HQ and key manufacturing complex in Hiroshima, Mazda plans to completely substitute the fuel supply at MCM Energy Service coal power plant away from coal by 2035, enabling “power generation based solely on the combustion of liquid ammonia”. The fuel switch is part of a broader strategy to achieve carbon neutrality across global operations by 2035.
