Thailand’s state-owned oil & gas organisation PTT and Singapore-based AET Tankers have agreed to jointly develop two dual-fuel Aframax vessels, with the intention of powering them with ammonia fuel. AET will select a shipyard for construction, with the two vessels to be delivered to PTT for long-term charters by early 2026.

Two recent announcements show Singapore emerging as a center for development of ammonia as a maritime fuel. In both cases, multi-party coalitions, with Singaporean connections, are focusing on ground-breaking work.

Welcome to the Ammonia Wrap: a summary of all the latest announcements, news items and publications about ammonia energy. In this week's wrap: HyDeal Ambition, new marine tankers, fuel forecasts & SOFC developments, a new technical briefing on power generation, UNSW leads research in P2X, GWs of green ammonia in Denmark, Norway and Chile, green ammonia in the Orkneys, new government focus on ammonia in South Africa, and India to make green ammonia production mandatory?

In November 2019, MAN ES published a technical paper describing the design and performance of its two-stroke green-ammonia engine. The paper also quietly announces the intentions of MAN ES to exploit ammonia energy technologies in a new business case, Power-to-X (PtX, "the carbon-neutral energy storage and sector coupling technology of the future"). In other words, MAN is moving into green ammonia fuel production.
