《International Journal of Hydrogen Energy》1987,12(11):783-803
Sources of energy from which hydrogen can be produced in massive quantity and at low cost are surveyed briefly. A short account of devices to be employed for the production of hydrogen are presented. Primarily the sun, sea and runoff waters are to be harnessed. The methodology and devices to be used to convert the available but diffused energy into hydrogen are helio-hydro-gravity, helio-aero-gravity, salt gradient solar pond, principle of magnetohydrodynamics, etc. The discussion on the inexhaustibility of naturally occurring sources utilized and/or harnessed in this process will lead to the low cost for hydrogen production. This process is imagined to be designed in a model city named ‘Hydrogen City’ which produces hydrogen and is run on hydrogen in order to meet its energy needs. 相似文献

Cities play a vital role in the global climate change mitigation agenda. City population density is one of the key factors that influence urban energy consumption and the subsequent GHG emissions. However, previous research on the relationship between population density and GHG emissions led to contradictory results due to urban/rural definition conundrum and the varying methodologies for estimating GHG emissions. This work addresses these ambiguities by employing the City Clustering Algorithm (CCA) and utilizing the gridded CO2 emissions data. Our results, derived from the analysis of all inhabited areas in the US, show a sub-linear relationship between population density and the total emissions (i.e. the sum of on-road and building emissions) on a per capita basis. Accordingly, we find that doubling the population density would entail a reduction in the total CO2 emissions in buildings and on-road sectors typically by at least 42%. Moreover, we find that population density exerts a higher influence on on-road emissions than buildings emissions. From an energy consumption point of view, our results suggest that on-going urban sprawl will lead to an increase in on-road energy consumption in cities and therefore stresses the importance of developing adequate local policy measures to limit urban sprawl. 相似文献
