Potential Roles of Ammonia in a Hydrogen Economy
www.energy.govhydrogen delivery or off-board hydrogen storage is currently under evaluation by the DOE and the FreedomCAR and Fuel Partnership’s Hydrogen Delivery Technical Team. I. INTRODUCTION The low volumetric energy density of hydrogen—in both compressed gas and liquid forms— makes the storage of hydrogen a difficult problem for most applications.
DOE Hydrogen and Fuel Cells Program Record
www.hydrogen.energy.gov2) for storage onboard a hydrogen vehicle. Two physical hydrogen storage methods are considered: H 2 gas compressed to high pressure (350, 700 bar) and liquid hydrogen (LH 2). Theoretical minimum energy requirements are determined from exergy differences using the standard properties of “normal” hydrogen (25% para-H 2 spin

www.energy.govhydrogen at competitive cost. There are two key approaches being pursued: 1) use of sub-ambient storage temperatures and 2) materials-based hydrogen storage technologies. As shown in Figure 4, higher hydrogen densities can be obtained through use of lower temperatures. Cold and cryogenic-compressed hydrogen systems allow designers to store the
HYDROGEN: FUEL OF THE FUTURE
www.csustan.eduHydrogen storage and transport is a critical issue involving intense research. The problem is the low density of hydrogen gas. Three possible solutions have been proposed. These potential hydrogen delivery systems include compressed tube trailers, liquid storage tank trucks, and compressed gas ...
