Feasibility of sending hydrogen thru the NG infrastructure.
Feasibility of sending hydrogen thru the NG infrastructure.
(OP)
I'm rather skeptical of the "hydrogen economy" hype.
As an EE, I'm out of my area of expertise. I've be told
that because hydrogen is smaller and more viscose
than NG, it's impractical to send thru the NG infrastructure.

The other point is that unless hydrogen is extracted from water using electricy generated from renewable sources (wind etc), the best source of hydrogen is natural gas, so we're back to square one in terms of any concerns about non renewable resources and global warming.

I have heard of the compressers we use for NG being used for Hydrogen in industrial processes. Not sure if it would work to send hydrogen down the lines. There have been oil pipes changed over to NG service, so I imagine, if it NG pipes need to be changed to Hydrogen, it could be made to work. Not sure about the expense or if the old pipes with dressers in them would work well.
Personally I think hydrogen has too low of a fuel value to do much with. However, I haven't done any research on the posibilities.

However, this was for reservoir fluids with water, as well as H2S present.....for a transmission pipeline, you'd hope that the water and anything like H2S would be removed, so perhaps any atomic hydrgoen would recombine to H2 rather than enter the line pipe metal: that's what metallurgists are for- to answer these type of questions!

Thanks for the explanation. Yes, we have H2S slam valves for a reason. Not that our customers appreciate them, but our operators and safety folks sure do!
