The global energy landscape is undergoing a transformation towards more sustainable sources to reduce carbon footprints. Transition fuels like hydrogen and ammonia are emerging as promising alternatives to fossil fuels, offering a way to balance environmental concerns with economic growth. While hydrogen is versatile and produces only water vapor as a byproduct, challenges in production, transport, and cost hinder its widespread adoption. Ammonia, with its high energy density and existing market infrastructure, requires renewable production for true sustainability. Despite challenges, the hydrogen and ammonia economy is gaining momentum globally, with countries like Singapore leading in national hydrogen strategies and infrastructure development in the Asia-Pacific region.
