PE pipes used for NG seem "good enough" https://www.pe100plus.com/PPCA/HYDROGEN-TRANSPORT-IN-POLYMER-PIPES-FOR-NATURAL-GAS-DISTRIBUTION-TEN-YEARS-OF-EXPERIENCE-p1737.html
PTFE is known to be better. Fiber reinforcement is mostly an outside layer to increase pressure resistance. Putting PE or PTFE inside existing steel pipes would also work.
Spoolable FRP pipes up to 4" in diameter can fit on a truck. Rated for 200bar. Pre covid, this was quoted as $50k/km as full deployment cost with 10s of km per day buildout rate. Spoolable pipe that can fit on ships has no diameter limit.
I don't know details of manufacturing process, but spools, plastic pipe extrusion, and fiber reinforcement should be highly automatable.
I see you weaving... 1600% tariffs on 6 minute abs videos is sure to make us all rich.
deportations would have that effect. More empty housing.
The concept of a plan for mass deportations is I think the red states volunteering to pay for it all. Due process would make it expensive, and back up the courts to prevent other prosecutions in those states. If it is just round up brown people in trucks and drive them to Tijuana, then it could be cheap and quick.
But the half life of polonium 210 is just 138 days. other is a few days. radium 226 is 1602 years. Why couldn't the earth have started with a lot of radium 226? Checkmate round earthers.
I hear slavery improves productivity a whole bunch! It's never clear the period "again" makes reference to in MAGA
And banks losing money on housing, has never hurt banks before. The banks will be protected too. Thank god, our banks will be saved again.
Corporatist PR slogans and promises is not a path to human sustainability.
Plastic/FRC pipes solve the leakage problem. They are also salt water resistant. Soft steel NG distribution pipes have low leak rates as well. Converting hard steel NG transmission pipes is possible by lining them in plastic. In any near future, H2 only new pipes would be built. H2 is more valuable when it is pure because it has higher efficiency electric conversion than NG, as well as being an ingredient to several important chemicals.
Green H2 does not benefit oil industry at all. It is only basis for a H2 economy because such an economy has to be 100% clean (FF derived H2 has less net energy content than original FF), and the essential rationale for an H2 economy is one where enough renewables to provide 100% of electricity every day needs to overproduce on most days, and H2 electrolysis is an automated way of providing transportable/exportable fuel that converts to electricity at high enough efficiency. The transportation cost advantage of H2 over electric transmission is enough to overcome the efficiency loss of creating it when the electric energy is cheap enough. 2-4c/kwh is enough for cheaper energy delivery by H2.
While Toyota has made great research/development in fuel cells, I agree that they have had a “don't buy an EV until you see our next model of the Mirai”, and oil companies bs about “blue H2” potential as path to fish for more subsidies, the anti-H2 fan boys are actually EV/battery investors. H2 economy requires batteries, and does have vehicle applications, but the main reason for it is that it is only path to 100% renewable energy.
The good match for wind, and offshore wind especially, is that many places achieve full electric demand coverage from solar alone on some days. On those days, adding batteries with more solar could achieve solar coverage over 24 hours. If it is windy at the same time, no wind energy would get sold those days, and then no additional renewables would be economic in that region, and higher demand days would not get covered by renewables. H2 is path for, wind especially, to sell/monetize all of their energy produced, but also bypass, for all renewables, grid transmission bottlenecks that monopolies don't mind being bottlenecks if it increases their discretionary power in providing energy permission.
They have no qualms about taunting a nuclear powered Russia. The return of a CIA puppet like Yeltsin is not likely, but just as Ukraine, there is not the slightest US concern for the welfare/benefit of people. Just destruction, hike price of oil, sell a lot of weapons, and buy the ruins for cheap.
H2 only FC ebikes are not well developed or popular yet. Drones with FCs are actively developed as density/weight is a huge factor for range. Very small fuel cells, 500w or 1000w have applications in powering a home (with solar supplement) because they can run 24/7 and charge batteries. Hooking up torches or burners to these cannisters can also provide clean indoor cooking or heating a box of sand/water in a room.
For an ebike, it is touring/camping applications that this really enables. Charging a battery when you need extended range, and it becomes worth the extra weight. Even a 100w fuel cell slow charging a spare battery while riding is big range extension, and provides overnight full charge. Combustion cooking and heating is fine for high supplementary energy.
A H2 economy would have these cartridges in similar locations to swappable propane tanks.
Toyota research and products are ahead of their time relative to cheap green H2. This is an advance over using 300bar "paintball tanks" by going to 525bar, and it looks a bit like an apple product design. Needs far more electrolysis production capacity and deployments. The global project pipeline is long though, so we should get there. Current focus is on large scale electrolyzers with specific offtakers which is slow, but a step towards broader distribution.
