a desirable thing is pipes carrying high pressure flammable gas.

As I said show in my earlier post you are seeing great advancement in range with the aim of 1 000 km range as well as 10 minutes charge. There China already have three minutes battery swaps.

NIO Completes 1 Millionth Battery Swap

NIO announced that the cumulative number of its EV battery swap service in China - the NIO Power - has reached 1 million, as of October 5, 2020.

I've often wondered about battery swaps. Ecologically, this is huge. They can start making the rest of the car to last for many decades, instead of 5-10 years. That article mentioned that one EV was swapped 500 times. Incredible!

Have you not started a shift towards plastic piping? That sooner or later the pipes have to replaced and then plastic seems like a better option that can also be used for hydrogen.

And I will believe a 1000 km range, when it hits the market.
It all comes down to energy density, batteries weigh too much, for the energy they carry.

You can already accomplish a 1000 km, 637.5 miles range during ideal conditions. There you also are seeing a lot of innovation and technology advancements to increase the range.

I am not sure you understand that, while pure hydrogen can do the job, it will require some fairly substantial changes to our infrastructure.
Simply making hydrocarbon fuels carbon neutral, would achieve the same goal, without changing the infrastructure.

If you had read your cited article, you would have seen the conditions.
" As always in these efforts, getting so much out of the battery meant turning the air conditioning off, driving slowly (on average, 29–31 km/h, or 18–19 mph), and prepping well. “The nearly 35-hour test took place at Lausitzring, a racetrack in northeast Germany. Dekra, a European vehicle inspection company that has operated at Lausitzring since 2017, monitored the test process and vehicles, recording 36 driver changes.”
So no AC at 18 -19 mph, I am not sure what mileage my F-150 might get at 18-19 mph,
but I suspect it is much better than under real driving conditions.

Natural gas (Methane) will likely be the last gas swapped out, because of the economics,
but that does not mean that it will not happen, or that they cannot solve the problems of hydrogen.
We know how long we can store methane for (Millions of years), hydrogen not so much.

Flammability danger aside, the biggest problem with hydrogen is that it is usually extracted from water with hydrolysis. By the time you expend energy to break that chemical bond, it is very difficult to get a NET positive energy from the hydrogen itself.

You will NEVER get a net positive from an energy storage methodology, otherwise you would be creating energy.
The reason natural gas will be last is because of how inexpensive natural gas is to find and extract, and transport.
The ease of transport, and the high hydrogen density per molecule, make it ideal for energy transport.
Consider the not in my backyard for Nuclear power, we need Nuclear power, but man do not want a plant near them,
yet power plants have very real line losses in power transmission.
What would happen if a Nuclear Power Plant were located in some remote location, but supplied massive amounts of carbon neutral
methane to the natural gas grid, power plants that burned the gas would be generating net zero electricity.

How do you get a "net positive energy?"

Where is this perpetual motion machine?

I hope we'll get past this by mass producing cheaper and cheaper modular nuclear power plants that are meltdown-proof, that don't need pressure vessels, and fail into a safe state that no one has to worry about. Nuclear is already the safest form of power by the numbers, when people acclimate to how safe it really is by addressing the few issues we still have, hopefully nuclear literally in your backyard would be something we could get to a level of comfort with. Not sure when you compare resistive heating vs sabatier methane generation and then burning the resulting methane, which of the two is the least wasteful of energy, (but I expect the resistive heating is, even better would be ground heat pumps) but all the distribution infrastructure for natural gas would seem wasteful (except where it already exists of course)

I think the real benefit for creating man made carbon neutral natural gas, is the energy storage factor,
and how it could separate the electricity supply from instantaneous demand.
This would be especially helpful with irregular sources like wind and solar.
While I know energy storage is always at a loss, using the energy that exceeds demand from wind and solar
to make heating and transport fuels. I am not sure what process the Navy and Sunfire are using,
but Sunfire is claiming an 80% efficiency, in it's power to liquid process.
I agree with you about the small nuclear reactors. I could see something like the NuScale reactor,
providing the heat for old coal power plants, as they all have ether rail or water access.

While Judith Curry and other fringe scientists like her have so little credibility that federal agencies, under the control and scrutiny of Donald Trump and Republican climate denier in Congress, continued to acknowledge the urgent need for action.

"The impacts of climate change are already being felt in communities across the country. More frequent and intense extreme weather and climate-related events, as well as changes in average climate conditions, are expected to continue to damage infrastructure, ecosystems, and social systems that provide essential benefits to communities. Future climate change is expected to further disrupt many areas of life, exacerbating existing challenges to prosperity posed by aging and deteriorating infrastructure, stressed ecosystems, and economic inequality. Impacts within and across regions will not be distributed equally. People who are already vulnerable, including lower-income and other marginalized communities, have lower capacity to prepare for and cope with extreme weather and climate-related events and are expected to experience greater impacts. Prioritizing adaptation actions for the most vulnerable populations would contribute to a more equitable future within and across communities. Global action to significantly cut greenhouse gas emissions can substantially reduce climate-related risks and increase opportunities for these populations in the longer term."

This “exceptional” level of annual additions will become the “new normal” in 2021 and 2022, the IEA says, with the potential for further acceleration in the years that follow.
