Hydrogen Hype is Dying, And That's a Good Thing

[progree]

9. The reason I bring up the thermal power plant at all is because your citation from energyknowledgebase

about the 65% "Losses of electricity through the delivery system" is applicable to a thermal power plant producing the electricity, so the reason I went through this thermal power plant thing is just to explain what this citation means.

That's the only reason I brought it up. You cited the 65%. I explained it. Every time you make that citation, I will explain that by far most of that is internal to the thermal power plant.

I think the energyknowledgebase wording, calling it the "delivery system", is poor, since as a former electric utility engineering professional (MSEE) in the electric power industry (Xcel Energy), formerly superintending the operational planning department, we think of "delivery system" as meaning the transmission and distribution system, i.e. the power lines. I think most non-engineering non-power-system professionals on DU would read it that way too.

To recap the systems in my post are, just to list them, whether or not they are important to the discussion of green storage systems or green energy production

41% efficiency thermal power plant (100%-54%-5%). Most are less efficient than that)

Storage system:

Hydrogen storage system electricity-to-electricy 34.8% efficiency
-or-
Battery storage system electricity-to-electricity about 80% efficiency

Transmission and distribution (the power lines) are about 10% losses combined, i.e. 90% efficient

I would not have brought up thermal power plants at all otherwise, as I think their efficiency is irrelevant and beside the point when we're discussing the efficiency of various storage systems.

..to be a worthy method of producing Hydrogen, since our only reason to produce H2, and our overarching goal, is the elmination of the use of fossil fuels. Green Hydrogen (which does not use any fossil fuels at all) is the only thing anyone should be discussing.

I agree, therefore I would urge you not to use citations applicable to thermal power plants, or, if you do, at least explain what it is (or include the next 2 paragraphs in the citation), and then explain why you are using a thermal power plant efficiency number in the first place.

Exception: nuclear thermal power plant - I will defend the right of those to be in the conversation.
