Storage and safety issues of hydrogen as an energy vector

CIM Montreal 2007
Abstract The challenge of satisfying ever-rising global energy needs in the face of depleting fossil fuel resources, coupled with an increased awareness of the public of the environmental impact of our energy system have brought attention to the possibilities of using hydrogen as an energy vector in a clean and renewable energy system. To achieve penetration on the energy market, hydrogen must overcome obstacles in the areas of storage, safety and infrastructure. One of the most important is the onboard storage of hydrogen for transportation applications, where large performance gaps exist between the current state of the technology and user expectations. In order to develop and demonstrate viable hydrogen storage technologies for cars, a set of gravimetric and volumetric system targets have been proposed by the US Department of Energy (DOE), based on achieving a driving range of 500 km for a hydrogen powered vehicle. Another key issue is safety. Although some of the safety issues can be arguably assigned to misperceptions, hydrogen has specific properties that have to be addressed, particularly in confined geometries where the risk of hydrogen detonations becomes an issue. In this talk, an overview of the storage and safety issues and possible solutions will be presented.
