Ammonia ship completes demonstration voyage

Japan’s New Energy and Industrial Technology Development Organization (NEDO) says that the world’s first commercial-use ammonia-fuelled vessel, Sakigake, has successfully completed a three-month demonstration voyage, during which the vessel engaged in tugboat operations in Tokyo Bay, while achieving greenhouse gas (GHG) emission reductions of up to 95%. The vessel was completed by Nippon Yusen Kabushiki Kaisha (NYK) and IHI Power Systems in August 2024, in cooperation with Nippon Kaiji Kyokai (ClassNK) as part of a Green Innovation Fund Project. NEDO says that the vessel will continue to be used for tugboat operations in Tokyo Bay, and the organisation will continue to promote research and development of next-generation fuel vessels, including developing an ammonia-fuelled ammonia gas carrier, in conjunction with NYK, Japan Engine Corporation, IPS, and Nippon Shipyard. This vessel is scheduled to be delivered in November 2026.

Mabanaft and HIF Global to accelerate methanol adoption in the shipping industry

Energy company Mabanaft and HIF Global have signed a heads of agreement for the offtake of e-methanol from, HIF’s planned e-Fuels facilities, reinforcing their commitment to advancing carbon-reducing fuels for the shipping industry. The initial offtake would be of up to 100,000 t/a of e-methanol produced from renewable electricity and captured CO2 per year. As HIF Global moves forward with the development of its e-Fuels facilities, Mabanaft says that it will further explore demand for different methanol applications jointly with its customers.

Record-breaking growth in renewable power capacity

Renewable capacity statistics 2025 released by the International Renewable Energy Agency (IRENA) shows a massive increase in renewable power capacity during 2024, reaching 4,448 gigawatts (GW). The 585 GW addition last year indicates that renewables claimed a 92.5% share of the total capacity expansion in power generation, and a record rate of annual growth (15.1%). Even so, progress still falls just short of the 16.6% growth needed to be producing 11.2 terawatts of energy by 2030. Progress also reflects significant geographic disparities. As in previous years, most of the increase occurred in Asia, with the greatest share being contributed by China- almost 64% of the global added capacity. G7 and G20 countries respectively accounted for 14.3% and 90.3% of new capacity in 2024.

Low temperature ammonia cracking technology

Mitsubishi Heavy Industries is developing a low temperature ammonia cracking technology (HyMACS™ ) that leverages exhaust heat from existing sources, such as boilers, steam turbines, engines, and heating furnaces. This innovative approach, which also includes the development of more efficient membrane separation technology using molecular sieves for hydrogen purification, is designed to offer a more sustainable, reliable and cost-effective pathway towards hydrogen production.
