Climate change is a world wide problem. Most of the planet has ready access to electricity for charging EV's.......hydrogen not so much
If it wasn't for electricity we would have choked ourselves to death by now. However as we shift to EV's we will need a new power grid to support it, one that is green and secure from being fucked with by hackers too. To charge that F-150 from flat takes a Helluva a lot of juice and as the range increases, so will the amount of power that will need to be dumped into the battery.

Hydrogen doesn't make sense, but recent developments have made storage practical, production is the issue though. It might find a place in the future and this could help it. Also coating the inside of a hydrogen tank with a single layer of graphene makes it impervious to hydrogen leaking out.

Here is a breakthrough for hydrogen storage.
Hydrogen makes sense to me for commercial transport: aircraft, trains and heavy trucks. Producing it is easy if you have enough wind or solar.

In terms of storage of electrical energy, we need the next step beyond chemical batteries. They have an energy density limitation. Their big advantage is that they are not prone to very sudden release of megajoules of energy, like kinetic or capacitive systems are.

Iron air looks good for grid storage

Grid storage is less sensitive to energy density.
Iirc China is developing iron-phosphate batteries for cheap EVs that don’t need a ton of range.
I fly FPV drones and RC planes that are eclectically powered with either Lipo's or Li on batteries and look forward to double or triple the range, performance and endurance.

Here is another thread of mine, haven't been out flying much this year, it's my retirement hobby, but over regulation is killing aspects of it.

Definitely not very efficient to run water hundreds of miles to the desert, but don't worry, that style of living is very finite.
With the amount of money living in the desert here, we’ll get a new water source. Either piped from the PNW or separated from the sea.

Desalination is the answer. Powered by solar.
Until we get aneutronic fusion. Solar and wind are great for general use, but having a reliable high power generation capacity is valuable for heavy industry and electrified transport.

I am ambivalent about fission energy. On the one hand, the safety and disposal issues are no laughing matter.
On the other, it is reliable no-carbon energy. We may do well using more of it. Especially in Europe, so that Russian pipeline becomes less of a bargaining position.

Fission is short term gain long term headache for our kids who will laugh at the technology, solar is the bridge until fusion reactors come on line imo but I agree we all need more energy self sufficiency

I’m not as down on fission as you. I know it is more dangerous, Fukushima taught us that as Chernobyl and TMI could not.

But when I run cost/benefit, fission still looks better than bad.

So long as we are on the way to developing better tech. Someone else thinks so too.


I’m hoping this will pry some more funding loose in the West.

It’s difficult to factor in future costs when we don’t know the environmental damage the ongoing uptick in background radiation is causing so it seems sensible to reduce radioactive emissions as we are carbon. The costs are more than just financial so I’m for upscaling renewables more than increasing fission power.
