This presentation will first review the regulatory status for hydrogen transport vessels, motor vehicle fuel tanks, and stationary storage vessels.  In regard to hydrogen transport vessels, the presentation will examine some of the standardized vessel features that have been developed over the years under US DOT, Transport Canada, and ISO regulations.  These design features and their utility will also be evaluated based on their potential applicability for motor vehicle fuel tanks and stationary storage vessels.

The presentation also reviews draft motor vehicle fuel tank standards HGV2, EIHP, and ISO15869 in terms of their impact on cost, performance, and operation of hydrogen vessels.  In addition, the presentation will cover some of the experience gained in developing first, second, and third generation hydrogen fuel tanks for autos and transit buses to identify design features that impact fuel tank cost and performance.  Recent advances in vessel sizes, service pressure, and materials of construction will also be discussed for different types of vehicle fuel tanks.

 The presentation will also examine the current regulatory status for stationary storage vessels and key developments of standardized products for this usage. 

Lastly, the recent development of high pressure cryogenic vessels will be discussed.
