Quantity Measurement for Low Carbon Fuels

A*STAR National Metrology Centre (A*STAR NMC) has collaborated with MPA and bunkering stakeholders to develop standards supporting the regulatory use of bunker Mass Flow Meters (MFMs). Since the MPA mandated MFM usage in 2017 under SS 648 (ISO 22192), A*STAR NMC has validated measurement data on over 500 MFM systems installed on bunker tankers.​

Ammonia (NH₃) is an emerging marine fuel where accurate quantity measurement is critical for fair trade. With NH₃ demand projected to reach 2 million tonnes per year by 2035 (DNV, 2024), a mere 0.5% measurement error could result in a discrepancy of 10,000 tonnes—equivalent to US$8.2 million. These financial risks will escalate as NH₃ demand grows in support of the 2050 Net-Zero ambitions.​

Following the world’s first NH₃ bunkering trial in 2024, MPA is developing a Technical Reference (TR) for NH₃ bunkering, targeted for publication in Q2 2026. In parallel, A*STAR NMC has established a research roadmap to address the precise quantity measurement needs for both NH₃ and LNG.​
