Let’s take a couple things you’ve said and compare them to the link you just provided me. You said that the cost of hydrogen pipelines was equally inexpensive as methane / natural gas. Yet in the abstract of your link,
The results indicate that the cost of electrical transmission per delivered MWh can be up to eight times higher than for hydrogen pipelines, about eleven times higher than for natural gas pipelines, and twenty to fifty times higher than for liquid fuels pipelines
Now how could nat gas be 11x cheaper than electricity but hydrogen is only 8x if they cost the same? That sounds like it’s 37.5% more expensive per MWh delivered. Interestingly, to deliver 1 MWh of hydrogen, you only need to deliver 30kg. Of course, the LCOE of that 30kg of hydrogen is hilarious compared to methane gas power plant.
And, of course, the very next paragraph dives into that.
The higher cost of electrical transmission is primarily because of lower carrying capacity (MW per line) of electrical transmission lines compared to the energy carrying capacity of the pipelines for gaseous and liquid fuels
That’s only true for DC, not for AC transmission lines which regularly move 900 - 2200 MW of power. Not that it’s even a point that matters much, since most power plants don’t produce 2200 MW of power at one location. We tend to distribute the generation for reliability reasons at the very least.
Now, are you ready for the kicker? I mean, are you really ready for me to just put the final nail in this coffin for you? What kind of electricity transmission are they comparing pipelines to in this link?
HVDC
And there it is. The cost of HVDC is overwhelmingly dominated by AC to DC and DC to AC conversion hardware, as noted by EIA in their reports. But, of course, if you compare to AC transmission as I mentioned above, this entire report is so upside down that it’s laughable. And that is why we have electric transmission lines rather than natural gas generators at every home and business in the entirety of the US. You should read the whole report, it’s really full of a lot of fun tidbits like this.
You basically picked the highest cost method of electricity transmission with the least adoption, and wondered why piping natural gas was cheaper. The fact that the into to the research said that electricity was hard to move at such high MW levels was the first clue that something was wrong here. That’s a rookie mistake for you.
You’re just engaging in more obfuscation. 8x and 11x are pretty close to being 10x cheaper. It is sufficient for physicists or engineers to just say it is 10x as a first-order approximation.
Even the EIA link I supplied shows that the conversion electronics are 60% of the cost of HVDC. Now you respond with Australia Pipeline & Gas Association? lmfao Dude. Come on.
If HVAC was really that much cheaper, there would never be HVDC connections in the first place.
Ok, now I know for a fact you don’t understand what you’re talking about. The only reason HVDC is a thing is to reduce transmission losses on very long runs. Something that we don’t really do in the US, and the most popular installations are in Europe where nations sell energy among EU members. The increased cost serves multiple purposes in that case- It reduces transmission losses as I said, but it also allows you to build more compact systems, and you get less capacitance issues in under ground and under water installations. It’s honestly crazy you’d even say that.
How about you actually read my link? I clearly stated that at long-distances, HVAC become inefficient and therefore costly. Your link is not comparing them to pipelines.
Making things up, got it. BTW, the luddites were correct. You might want to actually look up what their concerns were rather than just repeat bullshit. Like reading a gas company’s research that says piping gas is cheaper than running electricity. BTW, do you find it strange that nearly every structure in the US has electricity running to it, but not gas? Hmm. Makes you wonder. Well, makes me wonder. I’m sure you’ll just blame some climate change denial conspiracy.

Here’s a fun EIA link talking about HVDC transmission line cost per mile https://www.eia.gov/todayinenergy/detail.php?id=36393 and the report linked to from that page, which EIA commissioned. https://www.eia.gov/analysis/studies/electricity/hvdctransmission/

AC suffers from more losses at long distances. It is also quite expensive. Both HVAC and HVDC are more expensive than pipelines: https://www.apga.org.au/sites/default/files/uploaded-content/field_f_content_file/pipelines_vs_powerlines_-_a_summary.pdf
You cannot fudge your way around the facts. If HVAC was really that much cheaper, there would never be HVDC connections in the first place.
No, I was building a case. And you very clearly do not understand what’s being talked about in that research. Claiming that AC transmission lines are as expensive to build as HVDC is absurd in every way. https://web.ecs.baylor.edu/faculty/grady/_13_EE392J_2_Spring11_AEP_Transmission_Facts.pdf

Yeah, we’re done here. You’ve moved the goal posts so much we aren’t even on the same field.
You’re completing making shit up and none of your arguments are even relevant to the conversation. Fuck off with your Ludditism.

A huge number of structures have gas piped in. Not sure what you’re even arguing here.
