Episode 25: A Grain LNG Story: How AI, Granular Data, and Certification are Driving Commercial Advantage

In this episode of Methane Talks, we sit down with Jeremy Metcalfe, Future Development Manager at Grain LNG, and Maria Kuosa, CEO of Aeromon, to explore how voluntary methane initiatives are redefining operational priorities and unlocking competitive advantage in the LNG sector. 

Grain LNG made headlines as the first LNG terminal globally to achieve MIQ certification, a milestone that began as brief discussions back in 2019 and evolved into a robust methane management system. Jeremy shares the journey from early infrared surveys to embedding continuous improvement into the terminals, and why external stakeholder assurance is critical for credibility in today’s market. 

Maria brings a technical lens to the discussion, explaining how Aeromon’s accredited site-level and source-level measurement capabilities are helping operators reconcile data and optimize maintenance cycles, through predictive strategies. We also dive into the challenges of quantification, the role of digitalization and AI in emissions reporting, and why granular data is key to unlocking actionable insights. 

Finally, we look ahead to the future of certified gas, MRV frameworks, and what “future-proof” really means for operators navigating regulatory flux and global climate goals. 
If you are looking for practical advice on building a methane reduction strategy that balances ambition with flexibility, and how collaboration between technology providers and operators is accelerating progress, this is an episode you won’t want to miss.
