Norsk deltakelse i IEA HIA Task 19 - Hydrogen sikkerhet

The objective of the project is to contribute to the international work in IEA Hydrogen Implementing Agreement (HIA) Task 19 for safe introduction of hydrogen as an energy carrier. This was initiated in 2004 by a number of countries, among them Norway. Th e main focus is directed at improving our knowledge on hydrogen safety and our ability to model hydrogen related risk and design safe hydrogen installations. A Norwegian consortium consisting of DNV, GexCon, Telemark University College (HiT) (and Statkraf t in 2005) has been central during the first six years of Task 19. Current phase of the work ends in 2010 and a new three-year phase has been conditionally approved by the IEA-HIA, providing the participants can secure financing for the drafted work plan. DNV is unable to participate in the next phase but the other 2 participants, and HiT and GexCon are devoted to continue. Among the Task 19 expert group are organisations with leading test facilities and important knowledge to fill global knowledge gaps as well as strong involvement in the development of regulations, codes and standards. There will be active cooperation with international partners, both in terms of sharing of methodologies, experimental data, input to design of experiments with numerical simulations, etc. A concerted research effort will also be made. Experiments in channels with multiple obstacles is planned by HiT to investigate the mechanisms of flame acceleration and DDT for flame obstacle interactions. Numerical simulations with t he HiT-CFD code for compressible reactive flow will be used to get better understanding of the mechanisms to be investigated, Simplified models for reaction rates will be validated with these experiments. GexCon's work will be primarily numerical involvin g continuing validation against experimental data for situations that have not been covered previously and further development of the CFD tool FLACS in several important areas.
