The production and escalation of hydrogen on a large scale is a goal toward the upheaval of green and cheap energy. During the last decades, many methods have been espoused to produce more hydrogen fuel. Right now hydrogen is hauled out from different sources, such as oil, coal, natural gas, water, etc. In case of water, the hydrogen is produced by different methods such as electrolysis, photosplitting, photoionization, photocatalysis, product analysis methods, etc. This review paper thrashes out the assessment of these assorted methods of hydrogen production from water.

“…Several authors (Fisher 1990;Okken 1992;Okken et al 1995) have evaluated the use of hydrogen as a method for minimizing greenhouse gas emissions to the environment. Two primary methods have been proposed: (1) hydrogen production using renewable resources (e.g., PV-electrolysis, biomass); and (2) the capture and sequestration of CO 2 from conventional hydrogen production technologies (e.g., SMR).…”

“…In ocean disposal, several options are available. Liquid CO 2 may be released from pipelines at depths of 2,000 m or more; solid CO 2 can be disposed of by ships; or CO 2 can be converted into clathrates/hydrates for disposal (Okken 1992). With underground sequestration, the CO 2 is injected into depleted natural gas reservoirs or other geologic formations such as aquifers (Okken 1992).…”

“…The ocean has a CO 2 uptake capacity that is almost 7,000 times greater than current carbon emissions. However, the CO 2 will not remain in the ocean forever and there has been little investigation into the impacts on marine ecosystems (Okken 1992). Okken (1992) estimates that there is a total of 5 years worth of capacity in old natural gas wells and an additional 15 years capacity in sedimentary basins.…”

The specific TCI for the residual oil case is significantly higher than that for a similar facility based on coker off-gas. This result is expected because of increased equipment for feed handling and impurity removal. For the facilities based on coker off-gas, there is a significant economy of scale with a resulting reduction in the price of hydrogen. A similar effect is expected for a facility based on residual fuel. Biomass Gasification As with coal gasification, biomass may be gasified using a variety of methods, primarily indirect and direct gasification. Indirect gasification, as exemplified by the Battelle-Columbus Laboratories and Future Energy Resources Corporation (BCL/FERCO) gasifier, uses a medium such as sand to transfer heat from the char combustor to the gasification vessel (Spath and Mann 1998). In direct gasification (e.g., the Institute of Gas Technology, IGT, gasifier) heat to the gasification vessel is supplied by the combustion of a portion of the feed biomass.
