My cents
General info.
1.Hydrogen flame has no colour…it burns with nearly invisible flame, flame gives “third degree burns”
2.grey hydrogen is also produced by caustic manufacturing company…it is a byproduct to them…in dahej gujarat…few years back…caustic manufacturers were willing to pipe out hydrogen for free.
3.Usually clusters of “Fairy circles” are naturally occuring hydrogen sites.
Critics
1.Hindenburg report on bloom energy, Hindenburg States no fuel cells has ever been viable (if i remember the statement correctly , the meaning was close i think) however bloom survived.
2.Hydrogen usage other than chemicals, were discarded but its widely used in space applications.
3.Biggest critic of hydrogen mobility is “Toyota Mirai”…the technology is fully developed but even after a decade the car never went to production assembly.( i mean its still being made but not on the volumes)
Direct uses
1.Hydrogenation is an age old process
2.Amonia production widely uses hydrogen
Conversion to electricity
1.Multiple technologies exist…even within same technology segments they have variying degree of differences(Bloom, Horizon, Advent, Fuelcell Energy,Ballard Power,Blueworld)
2.Each of the technology has its edge over other based on application.
Cost
1.Based on my understading…Hydrogen production is certainly going to be viable…I feel it will be soon !
2.Conversion on the other hand seems to remain costly affair for time to come ( since all the catalyst with which hydrogen reacts are made of noble metals…e.g. palladium, platinum)
3.There are conversion applications where cost is secondary.
Overall i am optimistic on hydrogen economy, if they do not take out the whole train. as they took out TRAMs because they had already invested in oil prospecting,drilling,distillation and wanted to sale more cars and only more cars can consume more oil while the TRAM on the otherhand was electric !
