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

Theoretical minimum energy requirements are determined from exergy differences using the standard properties of “normal” hydrogen (25% para-H 2 spin
An Introduction to SAE Hydrogen Fueling Standardization
www.energy.govVehicles (or Hydrogen Surface Vehicles, HSV) • Factors for success: • Fueling has to be within hydrogen storage system limits. • Fueling rate and driving range have to be acceptable to customer • Vehicles need to fuel at same as today’s rate. • Hydrogen Fueling is the only ZEV infrastructure technology
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 ...

Chapter 6.6 Hydrogen sulfide - World Health Organization
www.euro.who.intHydrogen sulfide is the main toxic substance involved in livestock rearing systems with liquid manure storage (8). It is also a hazard at waste treatment facilities. Conversion factors 1 ppm = 1.5 mg/m3 1 mg/m3 = 0.670 ppm Routes of Exposure The respiratory system is the main route of human exposure to hydrogen sulfide both in
COMMUNICATION FROM THE COMMISSION TO THE …
ec.europa.euHydrogen is enjoying a renewed and rapidly growing attention in Europe and around the world. Hydrogen can be used as a feedstock, a fuel or an energy carrier and storage, and has many possible applications across industry, transport, power and buildings sectors. Most importantly, it does not emit CO 2 and almost no air pollution when used.
