Hydrogen Fueling Safety Assessment Case Study

The Challenge

The California Energy Commission is directed to assist in the development of clean alternate transportation fuels. As part of this effort they are supporting the commercialization of fuel cell vehicles operating on hydrogen fuel. In order to be used extensively in the transportation sector, the safety of hydrogen production, storage, and supply needs to be addressed. This will require evaluation of different alternate designs for supply of hydrogen at fueling stations.

Our Approach

Four alternate technologies for hydrogen supply were selected including: delivery of hydrogen gas by tube trailer, delivery of liquid hydrogen by truck, reforming of natural gas and electrolysis. The plan was to conduct a failure modes and effects analysis of these four technologies based on existing designs and for comparison, to also review two compressed natural gas fueling designs.

The Benefits

The results were used to identify potential failures in hydrogen and compressed natural gas fueling stations, assess their potential consequences, and evaluate whether existing safeguards are adequate.
