Harmonised certification – opportunities and challenges across different markets

Geofrey Njovu November 26, 2023

In this session at our 2023 annual conference, panelists explored the challenges and opportunities for designing certification schemes for different markets. Moderated by Madhav Acharya, the discussion featured Emily Wolf from Ambient Fuel, Claire Behar from Hy Stor Energy, Domagoj Baresic from the UCL Energy Institute and Patrick Hastwell from KBR.

Compliance with EU standards offers flexibility for producers and will facilitate the immediate scale-up of export markets, but progress towards an umbrella-style certification scheme remains in focus for the AEA. Broad-based certification schemes will help create new voluntary demand markets and avoid a sector-by-sector approach to developing certification.

Data-driven, carbon intensity-based certification

Geofrey Njovu November 26, 2023

In this session at our 2023 annual conference, panelists discussed how ammonia certification methods should be data-centric, and focus less on colour labels. The panel featured Alicia Eastman (InterContinental Energy), Shigeru Muraki (Clean Fuel Ammonia Association), Wouter Vanhoudt (Hinicio), Linda Dempsey (CF Industries) and Conor Fürstenberg Stott (Fürstenberg Maritime Advisory).

Certification based on actual GHG emissions intensity is the principle on which the AEA’s certification system is being built, and the issue is becoming an increasingly important subject at international fora such as the IMO, the G7 and the G20.

Ensuring credible data inputs for ammonia certification

Geofrey Njovu November 26, 2023

This session of our 2023 annual conference explored the need for high quality data as an input to ammonia certification. The panel featured Jennifer Beach (Starfire Energy), Lara Owens (MiQ), Jim Seely (Authentix), Selim Sevikel (Global CCS Institute), and Rajiv Sabharwal (Bureau Veritas).

This issue is a key focus for the AEA, as our under-development ammonia certification system will require auditable data from a host of stakeholders – including gas and electricity suppliers, CO₂ offtakers, and others – in order to calculate a true and trustworthy carbon footprint.
