homolytic cleavage. Carbamide peroxide contains approximately 35% hydrogen peroxide and forms hydrogen peroxide and urea in liquid solution. 750,000 tonnes hydrogen peroxide (calculated as 100% H2O2) were produced in Europe in 1995. The main usage of hydrogen peroxide is in production of chemicals and bleaching of cellulose pulp and textiles.

B. Low Ignition Energy. Amount of energy needed to ignite hydrogen fuel is too less than gasoline. (0.02 MJ for hydrogen and 0.2 MJ for gasoline). It creates proper ignition of hydrogen. There may be chances of pre ignition phenomenon or flash back due to low ignition energy. Syngas H C. Small Quenching Distance. Hydrogen has a very small

Producing hydrogen by passing an electric current through water is energy-intensive, consuming 50 to 55 kWh/kg hydrogen produced and resulting in a high carbon intensity of more than 21 kgCO 2 e/kg hydrogen. This would not be green hydrogen since the greenhouse gas (GHG) emissions attributed to grid power are substantial (see Table 1).

Green Hydrogen Guidebook Second Edition.pdf Typical hydrogen blends in natural gas pipelines range from 3% to 15% hydrogen by volume. The highest concentration of hydrogen reported by any U.S. gas utility is in Oahu, Hawaii, where Hawaii Gas's natural gas pipeline contains approximately 12% hydrogen gas.

modular units suitable for forecourt (fueling station) on-site production. Production capacity is the major determinant for these two pathways. The central hydrogen conversion plant is sized to supply regional hydrogen markets, whereas the forecourt capacity is sized to meet local service station demand. Table 1 IHIG Hydrogen Pathways

The compressed hydrogen was stored in light weight, aluminum lined carbon fibre reinforced cylinders at a pressure of 43.8 MPa. The hydrogen was dispensed through a 35 MPa dual hose hydrogen/compressed natural gas (CNG) dispenser. In 2003 the existing 35 MPa fueling station was upgraded to dispense hydrogen at 70 MPa (10,000 psi).
