At ABLC 2025, several key aspects of progress and opportunities related to hydrogen were discussed.

• Green Hydrogen Production and Project Development: Aerial Green has a dedicated focus on bio conversion and hydrogen. They supported a green hydrogen project utilizing SOEC technology by developing the feed package and managing the FEL (Front-End Loading) stages to de-risk the project for potential FID (Final Investment Decision). This indicates active project development in the green hydrogen space.

• Syngas as a Hydrogen Source: SunGas Renewables focuses on renewable synthesis gas (“Syngas”) related opportunities. Syngas is a mixture that includes hydrogen, and SunGas has a FEED-ready project in Louisiana (Beaver Lake Renewable Energy). Afne Energy’s technology also produces hydrogen-rich syngas from biomass through a two-step process involving thermolysis and cracking.

• Hydrogen Integration with SAF: Linde presented on the “Opportunities for Integration of SAF and Hydrogen Plants”, suggesting a growing recognition of the potential synergies between these two areas of the renewable fuel sector.

• Hydrogen Carriers for Transportation: Axens highlighted Liquid Organic Hydrogen Carriers (LOHC), specifically mentioning MCH (methylcyclohexane), as a safe, efficient, and commercially viable solution for the storage and global ocean transport of hydrogen using existing infrastructure and safety standards. They also noted that LOHC is a cost-competitive solution compared to ammonia for hydrogen transport.

• Diverse Hydrogen Production Pathways: The discussion around power-to-liquids (PTL) touched upon various hydrogen production methods, including electrolysis and nuclear (pink hydrogen), indicating a broader consideration of different clean hydrogen sources for synthetic fuels.

• Hydrogen Blending in Engines: Vartselia (part of Marquis) is investigating green ammonia combustion concepts and related safety technologies. Their gas engines are also capable of blending up to 25% hydrogen in LNG, with concepts under development for 100% hydrogen use in marine engines.

• Hydrogen as a Feedstock: Sonata Bio utilizes waste gases, including hydrogen, in their biological fermentation process to produce ethanol and proteins. This demonstrates an innovative approach to upcycling hydrogen-rich waste streams.

• Ensyn’s Potential in Green Hydrogen: Enen’s product mix includes green hydrogen, suggesting that they are exploring or involved in its production, although details are not elaborated in the provided excerpts.

• Policy Support for Clean Hydrogen: The mention of the Treasury releasing final rules for the Clean Hydrogen Tax Credit (Section 45V, though cited as 45Z in relation to biofuels) indicates ongoing policy efforts to incentivize clean hydrogen production.

Overall, ABLC 2025 showcased progress in various aspects of hydrogen, including project development, integration with other renewable fuels like SAF, advancements in transportation through hydrogen carriers, exploration of diverse production pathways, and its role as a feedstock and in engine technologies. The discussions also acknowledged the importance of policy support for the continued advancement of the hydrogen economy.
