Design of Hydrostatic Pressure Retainment Tanks for Fuel Cell Vehicles 2004-01-1012

There is a great deal of attention being concentrated on reducing the weight of pressure vessels and fuel/oxidizer tanks (tankage) by 10% to 20%. Most efforts are focused at the use of new lighter weight high strength materials to achieve this goal. We propose another approach called Hydrostatic Pressure Retainment (HPR), which has the potential of reducing tank weights by nearly 40% while simultaneously increasing safety and versatility. HPR is an original invention of the authors, and represents a truly novel approach to light weight tankage.
