Hydrogen energy:

Fionnguala Sherry-Brennans aim of this paper was to investigate public

understanding of hydrogen energy using a particular socialpsychological theory,

namely, the theory of social representations to explore how processes of

understanding generated lay knowledge of hydrogen energy.[107]

Naim H. Afgana,,Ayfer Veziroglub, gives an overview of the potential of multi-

criteria assessment of hydrogen systems.[116]

Adnan Midilli and Ibrahim Dincera hydrogen is considered as a renewable and

sustainable solution for reducing global fossil fuel consumption and combating

global warming and studied exergetically through a parametric performance

analysis.[133]

Hydrogen Production:

Paul Kruger analysed the appropriate use of solar energy, chemical combustion

fuels, and nuclear energy on the basis of their specific energy.[36]

V. Utgikar and T. Thiesen explains the LCA which examines the environmental

impact of the combined advanced nuclear-high temperature electrolysis plant,

focusing upon quantifying the emissions of carbon dioxide, sulfur dioxide, and

nitrogen oxides per kilogram of hydrogen produced.[37]

Graggen demonstrated the combined pyrolysis and steam-gasification of

petroleum vacuum residue was performed using a 5-kW aerosol-flow solar

chemical reactor tested in a high-flux solar furnace in the temperature range

14201567 K.[38]

Zabaniotou etal reported experimental results of slow, fast and catalytic

pyrolysis of five lignocellulosic residues (corncobs and corn stalks, sunflower

residues, olive kernels and olive tree prunings. It showed that pyrolysis in the

captive sample reactor produced more H2-rich gas than in the fixed bed reactor,while the fixed bed reactor configuration seemed to favor the production of liquid

products.[39]

Domashenko etal studied the development and operating experience of large-

scale liquid hydrogen production, its long-term storage in tanks with highly

efficient insulation, delivery to customers by road and railway tankers, and

prospects of further progress of the country supplies with liquid hydrogen.[65]

GBattista etal proposed a novel control for a wind-electrolysis system, which

match the wind power output to the electrolyzer power requirements, thusgaining in system performance.[88]

Yutaka Tamaura *, Hiroshi Kaneko has proposed a thermodynamic study showed

that the ZnO was produced by the reaction between the O2 gas in the air and

the metal Zn vapor generated from ZnFe2O4. With the combined process of the

present study on the O2-releasing step and the previous one on the H2

generation step (ZnO + 2/3Fe3O4 + 1/3H2O = ZnFe2O4 + 1/3H2) for the

ZnFe2O4/(ZnO + Fe3O4)-system, solar H2 production[110]

Paul Kruger shown that even with improved energy consumption efficiency of

electrolytic production facilities, the additional electric energy demand to sustain

growth of hydrogen fuel production will require installation of signi5cant

additional electric power generating capacity throughout the world[119]
