The point is that electric versions do exist for farm vehicles are we are in fact weaning ourselves off fossil fuels, so no, we are not dependent on them as we have alternatives. All the issues you list are simply ones of logistics. The same with hydrogen, it is not only produced using methane from natural gas, but methane from biomass, so again we are not dependent on fossil fuels to cryeste hydrogen as there is an alternate source that we are using and ramping up.
Fossil fuels aren't going anywhere. This Woods Mackenzie report was before the 2022 rush to more coal, gas and oil, I might add. COP26 has been a horrific failure less than 12 months after it finished.
Yes, electric versions exist. Now tell me how much energy and resources will be needed to convert ALL agriculture to use this, and what costs farmers will have to swallow for it.
As Natural History Museum Head of Earth Sciences Prof Richard Herrington et al., warned in 2019:
“To replace all UK-based vehicles today with electric vehicles (not including the LGV and HGV fleets), assuming they use the most resource-frugal next-generation NMC 811 batteries, would take 207,900 tonnes cobalt, 264,600 tonnes of lithium carbonate (LCE), at least 7,200 tonnes of neodymium and dysprosium, in addition to 2,362,500 tonnes copper. This represents, just under two times the total annual world cobalt production, nearly the entire world production of neodymium, three quarters the world’s lithium production and at least half of the world’s copper production during 2018. Even ensuring the annual supply of electric vehicles only, from 2035 as pledged, will require the UK to annually import the equivalent of the entire annual cobalt needs of European industry…
So, yeah, having an alternative doesn't mean anything. We have literal oceans of hydrocarbons on the moon Titan to go and use when we run out of oil, so no big deal, right?
You are simply wrong about desal plants as well- as the ones using RO are more than economically viable and are being used on various remote islands. I helped install one on a British island for example, Ascension Island. Look it up. And there are no “dead zones” in fact the island has tons of sea life around it. Sea turtles, fish, whales, dolphins, and so on such that is is actually a protected Marine Wildlife Preserve. Not to mention it is creepily covered in crabs everywhere you look there are giant crabs on the rocks and land crabs in the interior. The only time any marine life get killed is when occasionally the undersea volcano erupts poison gas under the water. Ascension Island is the tip of an active volcano that spans from seabed to above the sea level.
Sure about the dead zones? I mean, it's simple chemistry.
Likewise, as I already pointed out, your use cases are completely irrelevant to modern industrialised uses. The water rates that allow agriculture to even exist, do not hold up with desal. Might want to ask yourself why everyone is draining aquifers in the south western USA and across all of India and Africa and China, instead of just using sea water.
One more about it being environmentally damaging.
