1 Pre normative research on the indoor use of fuel cells and hydrogen systems Project Overview B. L Hostis Final Dissemination Workshop, 11 December /12/2014

2 Hyindoor is a pre-normative research on safe indoor use of fuel cells and hydrogen systems Pre-normative research on safe indoor use of fuel cells and hydrogen systems 3 years (janv-2012-dec-2014) 3.6 M budget 1.5 M is funded by FCH JU Partnership: Industry: FC and Gas companies, Testing laboratories, Research Institute, Leading actors in RCS development, innovation & project management consultancy Coordination : AIR LIQUIDE 2 11/12/ Hyindoor WP6

3 Use of H2 in confined environments requires detailed assessments of hazards and associated risks, including potential risk reduction measures. The release of H2 can potentially lead to its accumulation and the formation of a flammable H2-air mixture. Safety design guidelines and engineering tools need to be developed for use with specific safety strategies for various HFC applications. HYINDOOR aims to provide scientific and engineering knowledge for the specification of cost-effective means to control hazards, and to develop state-of-the art guidelines 3 11/12/ Hyindoor ICHS 5 th

4 Description To address these issues, the European Hyindoor project ( ) funded by the Fuel-Cell & Hydrogen Joint Undertaking (FCH-JU) is conducting pre-normative research in order to: Hazard approach- Scenarios and criterias Analytical, Numerical, and Experimental studies Indoor H2 accumulations, vented deflagrations and under-ventilated jet fires Safety guidelines- Support to RCS Safe introduction of HFC in early markets Recommendations will be proposed to support Authorities and Industry in making enhanced RCS safe indoor use of fuel cells and hydrogen systems at a European and international level 4 11/12/ Hyindoor - WP1 T1.1 Project title

5 H2-air Phenomena to be understood in confined space DISPERSION Identify characteristic regimes of hydrogen dispersion Characterize and quantify the dynamics of the dispersion phenomena DEFLAGRATION Dispersion H 2 Accumulation H 2 Layer J e t Hydrogen-air deflagrations including deflagrations of localised and stratified, turbulent and lean mixtures Inertial vent covers Deflagration JET FIRE Specific hazards for initial unsteady stage of fire development Indoor fire Self-extinction of enclosure fire and deflagration potential following extinction 5 Under-ventilated and well-ventilated fires and associated thermal effects and hazards to life and property

6 Methodology Knowledge M1: Power for isolated sites M3: Special vehicles M2: Back-up power M4: Mobile power Models H2 Systems/Objects Exercise Risk Evaluation Air Liquide Methodology retained for the exercise ( based on AL. Rex) Scenarios, flowrates and probabilities, critical levels, safety targets, etc Results are representative? What are the weaknesses? Knowledge Gaps to be filled 6 Work Program for WP2/WP3/WP3

7 Project achievements 7 Develop the knowledge base required to be able to predict H2 behavior indoor and consequences in case of early or late ignition Define improved criteria for allowing hydrogen and FCsystems indoors Issue a safety guideline Sizing of enclosure openings or forced ventilation in function of H2 release parameters Sizing of the vent area for deflagration mitigation in relation to the accumulated inventory and obstruction in the enclosure Disseminate the project outputs through H2 safety community and industrials -24 publications published in professional journals or proceedings of international conferences, including 4 journal publications; 2 books and 2 book chapters Experimental and modeling results Jan 2013 => June 2014 Recommendations for RCS Published Dec-2014 Guideline published Dec-2014 on Advanced Research Workshop Sept 2013 Bruxelles Dissemination Workshop Dec TBD
