Safe H2 fuel handling and use for efficient implementation (SH2IFT-2)
Based on the findings of the first SH2IFT project on the safe handling and use of hydrogen, several research gaps were identified for future work. This motivated the creation of SH2IFT-2, aimed at developing new knowledge on the identified research gaps as well as facilitating the competence required for supporting the widespread use of hydrogen in the society.

The project will investigate the following:
• Measures to prevent the formation of explosive hydrogen atmospheres and toxic ammonia conditions in enclosed spaces by means of ventilation
• Damage potentials in ignited large high-pressure discharges
• Impacts of hydrogen jet fires on exposed equipment and passive fire protection (PFP) products 
• Differences between hydrogen and hydrocarbon jet fire exposures
• Mechanisms of degradation due to hydrogen-metal interactions in a defined application
• Strength-of-knowledge in risk assessments and the overall risk picture for a range of energy carriers used in different energy systems, with a view to provide science-based recommendations to stakeholders

RISE Fire Research leads the work package of experimental investigations (WP1) and is directly responsible for the conduction of jet fire experiments using gaseous and liquid (cryogenic) hydrogen. These experiments are aimed at evaluating the influence of jet fires on targets with and without passive fire protection (PFP) to investigate how PFP products created for hydrocarbon fires perform in hydrogen fires, making it possible to highlight points of strength and potentials for improvement. A test facility with a large hydrogen inventory is being built for this purpose.

SH2IFT-2 has been funded by the Research Council of Norway (NFR) and it is a collaborative and knowledge-building project (KSP). The project started on the 1st of October 2021 and runs until the 30th of September 2025. For more information, refer to the project website linked at the side.
