Yamna, a global green hydrogen investment company based in the UK, is exploring the Port of Salalah in Oman and four other international ports as potential hubs for green ammonia bunkering. The company, along with its partners, is focusing on producing green ammonia and other derivatives to drive the energy transition worldwide. In Oman, Yamna is part of a consortium that has secured a land block in Dhofar Governorate for a significant green ammonia project, aiming to play a crucial role in the decarbonization of the maritime industry. Yamna's vision includes the development of a global network of green ammonia bunkering hubs, with locations such as the Port of Salalah, Port of Rotterdam, Suez Canal, Port Algeciras, and Jurong Port in Singapore being considered. The company aims to produce cost-competitive green ammonia at strategic locations well-connected to existing and future bunkering hubs. The article highlights Yamna's involvement in several large-scale green hydrogen and ammonia projects globally, including in Oman, Morocco, Norway, and East Africa. The company has also partnered with J-Power to invest in green hydrogen and derivatives projects. In Oman, Yamna, along with EDF Group and J-Power, has secured a land block for a 1 million tonnes per year capacity green hydrogen project, with plans for wind and solar capacity installations. Yamna emphasizes the importance of green ammonia as a low-carbon bunker fuel, driven by regulations from the IMO and the EU to reduce GHG emissions in maritime transportation. However, the complete adoption of green ammonia as a fuel requires the synchronization of key enablers such as production competitiveness, technology advancements, infrastructure adaptation, and safety guidelines. The company underlines the necessity for these components to come together to establish a complete value chain for ammonia bunkering.
