Hydrogen, again..

That is a slog of an article... a reader's digest version would have been appropriate. Hard to read....

Produce electricity by solar and wind. Use that electricity to produce hydrogen by electrolysis. Inject that hydrogen into natural gas pipelines. Use that mixture to cook your dinner.

Trying to avoid the energy storage issue with wind/solar. You can only make hay when the sun is shining.

The issues with Hydrogen are in it's storage (molecule size) as well as heating value. It has 1/3rd the heat content as natural gas.

Pie in the sky likely.

Entropy is a b*tch.

Agree, but I think they should keep beating that dead horse. They might learn something. I assume there is some government money in this.

A big problem is hydrogen embrittlement. I was responsible for 7 hydrogen compressors. Two had bolting failures due to embrittlement. Our PhD's in research punched time on that failure analysis for awhile. You can't just throw hydrogen into any pipeline without some metallurgical research.
We used to throw all kinds of junk in the fuel gas header for the big cracking furnaces. We had analyzers on it and occasionally had to fine tune what we were dumping in it.
I personally think nat gas is the ultimate answer. We have plenty and it is relatively clean. Burn it in a boiler to feed a steam turbine/generator or fuel a gas turbine for peak electricity needs. Rock & roll.

Ahhh, cheap, plentiful and clean. What's wrong with that picture and why won't it ever work we ask??? Where's the crisis?? How can we run the country off the rails if there's an easy common sense answer?? Nah, that will be ignored so we can chase snipes in fairy land.

Agree Danny. I don't mind a little government and university research but anyone with half a brain can look at nat gas and see: "that's it".

I have all my money tied up in Solyndra Solar stock! Wait! I don't have any money....

“ Hydrogen has about one-third the energy content of natural gas in the same volume”

I’m hoping I’m interpreting this line wrong from the article, but it sure reminds me of ethanol in gas, or biodiesel. Less power but more tree hugging at more of of a cost.
