IASH 2026, the 19th International Conference on Stability, Handling and Use of Liquid Fuels, will be held 6 - 10 September at the Pierre Baudis Congress Center in Toulouse France. This biennial symposium will be comprised of four days of technical sessions with a separate poster session; a commercial exposition will run throughout the entirety of the symposium. The technical sessions will focus on recent advances in science and engineering related to all aspects of the fuel life cycle, while the exposition will provide an opportunity for organizations to highlight their expertise and new/innovative approaches and products for areas of application including fuel production, testing, use and quality assurance.

IASH 2026 will benefit individuals and organizations with a technical and scientific interest in the development, use, handling and stability of fuels; including fuel refiners and producers, distributors and fuel strategic reserve organizations, fuel testing laboratories, research organizations, engine and power generation OEMs, fuel additive suppliers and major fuel users. This is a unique event where delegates meet with international colleagues and attendees from industrial, government and academic organizations, providing a diverse perspective on the complex factors impacting fuel production, quality and use.

Abstracts are invited for submission to be considered for presentations or posters on any aspect of the fuel life cycle and use, including for fuels derived from fossil, synthetic and renewable feedstocks and pathways. Primary areas of interest include papers related to fuel production, stability, viability, unique properties and chemistry, carbon neutrality, handling, storage, end-use and cleanliness control. These may relate to any liquid fuels, including but not limited to gasoline, jet, diesel, marine, burner, and residual fuel oils; crude oils; synthetic fuels, reformulated fuels; and fuels or blend stocks derived from biological materials or other non-petroleum feedstocks.

TECHNICAL SESSIONS are considered for, but are not limited to, the following topical areas:

Please note, the accepted abstracts will determine the final list of session topics.

Abstracts of approximately 250 words, in English, are due no later than 23 February 2026, for both technical papers and poster papers.  Please submit your abstract electronically to Darnette Holbert via the Abstract Submission Form.  Papers based on original, previously unpublished research or studies are preferable, but not mandatory.   PowerPoint presentation drafts are due 30 days prior to the conference for review by the Conference Chair. Manuscripts are due on 2 September 2026.  Presenters will be eligible for a reduced speaker conference registration fee.
