IASH 2026

19th Conference of the International Association for Stability and Handling of Liquid Fuels

IASH promotes research, development and discussion into the issues of liquid fuel stability, handling and use from detailed chemical pathways, through microbiological degradation and remediation, testing and issues arising from distribution and use. Over the IASH lifetime, we have moved from a world of solely conventional fuels derived from crude oil to today’s reality of conventional fuels, synthetic fuels – including renewable fuels – as well as associated performance enhancing and stability additives. IASH continues to challenge the boundaries of science and understanding in all aspects of liquid fuels.

IASH provides a forum to facilitate and encourage the exchange of scientific knowledge by promoting research and experimentation on the scientific and operational factors affecting the stability and handling of liquid fuels during their manufacture, blending, transportation, storage and use. Our volunteers are drawn from a cross-section of government, academia and industry – and many are world-renowned technical experts in their field.
