Ammonia fuel for glass production demonstrated in Japan

Asahi Glass Corporation announced it has successfully used 100% ammonia fuel to produce architectural glass over two days of testing at its Yokohama Technical Center, with NOx emissions below environmental thresholds. The news follows successful ammonia co-firing tests to produce cement clinker by Mitsubishi UBE Cement Corporation.

Creating Ammonia Value Chain for the Smooth Transition toward Carbon Neutrality

According to the IHI’s ‘Group Management Policies 2023’ announced this May, Clean Energy business represented by fuel ammonia and others is defined as Development-focus Business, which would drive our future growth in parallel with Aero Engines and Space business. Our aim is to build and enhance the value of our entire ammonia value chain by implementing direct ammonia utilization technology especially for power sector, preparing infrastructure for transportation and storage and also developing new technology for green ammonia production. In the session, IHI’s effort to implement total value chain of ammonia is introduced, especially to use ammonia in thermal power…

NoGAPS vessel project enters next phase

The second phase of the NoGAPS project is well underway. Led by the Maersk Mc-Kinney Møller Center for Zero Carbon Shipping, a detailed plan for the design, operation and business case for the future MS NoGAPS vessel will be developed. Construction and delivery is expected in 2024-25. Also in Scandinavia, Viridis Bulk Carriers has been awarded AiP from Bureau Veritas for its ammonia-fueled, short-sea, bulk carrier design.

Mitigating emissions risks from ammonia-powered vessels

Technology solutions to manage emissions from ammonia-powered internal combustion engines will be commercially available on a similar timeline to the engines themselves, a new report from the Mærsk Mc-Kinney Møller Center concludes. Although the authors are confident ammonia combustion emissions (including the potent greenhouse molecule N2O) will be successfully minimised, key gaps include a lack of industry-wide emissions thresholds and a poor understanding of the well-to-tank emissions of ammonia fuel, particularly CCS-based ammonia.

Ammonia as a liquid for the future of aviation

Zero-emission aviation initiatives have mainly focused on using hydrogen or drop-in biofuels and sustainable aviation fuels (SAF) to replace fossil-based jet fuels to achieve near-term reductions in carbon emissions with minimal impacts on the global aircraft fleet and supporting infrastructure. Despite significant advances in the production of such fuels, scaling up manufacturing capability to be cost-competitive remains a challenge. This paper discusses ammonia as a carrier of green hydrogen for aviation, with near-zero emission. Ammonia is proposed as both a carrier of hydrogen as fuel and to provide cooling for compressor intercooling and cooled cooling air for core efficiency improvement,…

Exhaust gas treatment catalysts for ammonia-fueled engines

Ammonia is expected to be a promising zero-emission fuel because it does not emit CO2 during combustion. However, the exhaust gas from the actual ammonia-fueled engines contains unburned ammonia, nitrogen oxides (NOx), and nitrous oxide (N2O), and there is a need to develop technologies to remove these harmful substances. Unburned ammonia can be removed by a catalytic combustion method using a conventional oxidation catalyst, but NOx and N2O are simultaneously generated as byproducts. Therefore, Nikki-Universal has developed a new catalyst that can remove ammonia at high efficiency while reducing the generation of NOx and N2O. We have also developed a…
