Safe Hydrogen Fuel Handling and Use for Efficient Implementation 2

Alternative title: Sikker håndtering og bruk av hydrogen som drivstoff for tidlig introduksjon i markedet 2

Awarded: NOK 14.0 mill.

Hydrogen is an important vector in the ongoing transition to renewable energy sources. Insufficient knowledge about critical safety aspects related to large scale rollout of hydrogen technologies constitutes a considerable bottleneck for industry, government, end users and the general public. SH2IFT-2 aims to close critical knowledge gaps identified by stakeholders from industry and government through development and redevelopment of existing modelling tools, leak-, fire- and explosion experiments of various scale, but also research based input to guidelines for safe use of hydrogen. The project contains a large experimental program, including release of hydrogen and ammonia in confined, ventilated spaces, ignition of nonhomogeneous mixtures of hydrogen-air as a result of high-pressure leaks, and realistic fire scenarios with and without passive fire protection. The experimental results will be used to validate advance models, including commercial CFD code and phenomenological models. SH2IFT-2 will explore a risk-based approach for operational safety. Materials testing will be conducted to study material compatibility and degradation characteristics. Modelling and measurement of degradation processes will constitute a basis for lifetime prediction. Barriers for operational safety will be designed for risk-based guidelines for inspection planning. The development of new technologies constitutes a considerable challenge for conventional approaches to risk analysis and risk management. How good is the quality of risk assessments for new energy systems, and which factors are limiting for the quality? The strength of knowledge of risk evaluations for hydrogen systems will be investigated through studies of selected systems, including use of expert panels, questionnaires, blind-prediction, and comparative studies for different energy carriers. The project aims to make the risk evaluations meaningful and available for decision makers and other stakeholders.

Hydrogen is becoming a critical enabler in the ongoing energy transition, and it is expected that hydrogen will be applied in many different applications and industrial sectors. The safety-related properties of hydrogen, and the characteristic operating conditions of technical systems for producing, transporting and using hydrogen, implies that fires and explosions represent a significant hazard for installations with considerable inventories of hydrogen. To this end, it is essential to develop science-based solutions for fire and explosion protection, and to disseminate state-of-the-art knowledge to relevant stakeholders. The overall objective of SH2IFT-2 is to develop new knowledge on critical aspects of hydrogen safety, and at the same time facilitate the competence building required for supporting widespread use of hydrogen in society. The project will work to improve solutions for safe handling of hydrogen and hydrogen-based energy carriers by developing new, and improve existing, modelling tools, perform large-scale release, fire and explosion experiments, and provide input to guidelines for safe use of hydrogen. The combination of large-scale experiments, validation of advanced consequence models, risk based operational safety, and the critical evaluation of the strength of knowledge in risk assessments for hydrogen systems, represents a unique opportunity to progress the science on hydrogen safety significantly beyond the current state-of-the-art. The involvement of stakeholders covering the entire value chain of hydrogen production, transport and use, implies that the research activities will have high relevance for industrial applications. Close collaboration between leading research organisations and a wide range of Norwegian and international stakeholders from industry and government will address both societal and industry needs for knowledge and competence building, and thus secure existing and establish new value creation and employment in Norway.
