As per scientists and researchers, carbon dioxide from the sea water can be extracted for making hydro-carbons. The concentration of carbon dioxide in the sea water is 140 times greater than that of air. Carbon dioxide is present as 0.10 gram per liter of sea water. The scientists in the U.S. have demonstrated the ability to recover carbon dioxide and hydrogen from sea water and turn into liquid hydrocarbon fuel.
Recently, scientists at U.S. Naval research laboratory flew a model plane using a liquid hydrocarbon fuel sourced from ocean. Now researchers are going to study that how the conversion of ocean into hydro carbon fuel can be made economically. So it has surely become possible to convert ocean water into fuel. If it is done, it will be very useful and reduce the dependence on fossil fuels.
In order to convert sea water into hydrogen peroxide, scientists have used sunlight. This can produce electricity through fuel cells.
Scientists purchased daylight to show saltwater (H2O) into oxide (H2O2), which can then be used in fuel cells to get electricity. it's the primary photocatalytic methodology of H2O2 production that achieves a high enough efficiency to ensure that the H2O2 may be used as fuel inside a cell.
The researchers, led by Shunichi Fukuzumi at urban center University, have printed a report on the new methodology of the photocatalytic production of oxide during a recently out there issue of Nature Communications. The largest advantage of using liquid H2O2 rather than gaseous hydrogen is that a large amount of fuel cells used these days store fuel in liquid form, as the liquid kind is considerably easier to store at high densities. Typically, H2 gas ought to be either extremely compressed, or some cases, cooled to its liquid state at refrigerant temperatures. On the opposite hand, liquid H2O2 can be keep and transported at high densities far more simply and safely.
The issue is that that, as yet, there has been no efficient photocatalytic methodology of manufacturing liquid H2O2. (There are measures to create H2O2 that do not use daylight, however they may want such a lot energy that they're not sensible to be used inside a technique whose goal is to create energy.) Although the collection efficiency compares favourably with that of many different solar-to-electricity sources- for example, switchgrass (0.2%), is still abundant below the potency of standard star cells. The researchers expect that the efficiency can be improved within in the future by usage of better materials, within the photo electrochemical cell, and that they additionally commit to notice strategies to minimize the price of production.
