environments, and mitigation measures.<br />

ACTIVITIES AND<br />
RESULTS IN 2005<br />
Two Experts Meetings were con<br />
ducted in 2005:<br />
1. Experts Meeting March 67,<br />
2005, Paris, France<br />
2. Experts Meeting September<br />
67, 2005, Pisa, Italy<br />
This task was approved <strong>by</strong> the<br />
Executive Committee of the IEA Hy<br />
drogen Implementing Agreement in<br />
October 2004. The task currently has<br />
slower than anticipated, due to the fact<br />
that only two National Commitment<br />
months after the Executive Committee<br />
to achieve the required level of expert<br />
effort. However, an additional six com<br />
mitment letters were received during<br />
the last half of 2005 and progress has<br />
picked up consi<strong>de</strong>rably.<br />
SUBTASK A RISK<br />
MANAGEMENT:<br />
Subtask A Risk Management consists of<br />
three activities:<br />
• Survey of existing risk assess<br />
ment methodologies for relevant case<br />
studies<br />
• Comparative risk assessment of<br />
hydrogen systems with hydrocarbon fuel<br />
systems.<br />
• Probabilistic risk and conse<br />
quence analysis<br />
Activity A. 1: Survey of existing<br />
risk assessment methodologies<br />
for relevant case studies<br />
(Lea<strong>de</strong>r – Norway, Angunn<br />
Engebø, DNV)<br />
pared in December 2005 and is cur<br />
rently being reviewed and discussed<br />
<strong>by</strong> DNV and Subtask A lea<strong>de</strong>rship. It<br />
will be released for the review of IEA<br />
experts in February 2006 and <strong>de</strong>tailed<br />
discussion at the Task 19 meeting in<br />
March 2006 in Long Beach, CA, USA.<br />
The survey inclu<strong>de</strong>s: nomenclature<br />
regulations; co<strong>de</strong>s and standards on risk<br />
assessment; discussion on risk assess<br />
ment methodology; review of methods<br />
used in available studies; and summary<br />
of results.<br />
A total of seven example projects<br />
quantitative approaches – have been re<br />
ceived and reviewed. The assessment<br />
methods followed a representative set of<br />
standards and gui<strong>de</strong>lines.<br />
were:<br />
1. The selection and application of<br />
risk acceptance criteria for the example<br />
risk assessment and are also adapted<br />
to most company gui<strong>de</strong>lines and author<br />
ity regulations. There were no adapta<br />
tions to the acceptance criteria in or<strong>de</strong>r<br />
operation of hydrogen facilities. In the<br />
context of this survey, the acceptance<br />
criteria are a suitable tool for commu<br />
