That petition is advocating using hydrogen as a fuel to be burnt in an IC engine? Literally the worst solution possible. Terribly, terribly
inefficient.
I really can't wait to see the back of diesels, just so sick of their smoke, having to change lanes or overtake to avoid me or the kids breathing
their filth. Don't care about where the fuel comes from, it's the pollution that matters to me.
Petrol's, fine but costs heaps and isn't very clean.
Hydrogen, got nothing at all against it, looks really great but I can't mind the last time I saw anything other than a few busses using it.
EV's are great, sorry they just are. Still a bit limited in their range but day to day stuff just perfect. Too expensive? not really I
didn't spend much as far as cars go and a large part of that cost is offset by the cheaper fuel, almost all of the cost in fact.
Their only banning new combustion cars, I've never owned a new car in my life. Most cars will last at least 20 years with decent maintenance so
that's 20 years to get use to EV's. Too much nonsense about dwindling lithium or other misinformation pedaled by oil companies (same
situation as tobacco) etc., already they are manufacturing alternatives and some of the new batteries coming don't even use any rare minerals.
I recently tool out the pollen filter out the Fiesta, and OMG it was just black with soot, who really want's to breath that crap in? (unless your
a smoker then you might not care...)

In the 80s and 90s yes there was smoke about. Big n/a IDI mechanical buses belching out clouds of grey. Where do you live? Seeing a smokey derv is so
rare for me now.
When I went to South Africa and joined the 1st motorway I couldn't believe the amount of trucks pumping out insane amounts of diesel smoke, it
was like they were all on their last legs. But here in the UK? Rare as hen's teeth round here.

I used to think hydrogen might be the answer, but various sources have shown me that (A) it's not really practical, as it has to be kept at very
high pressure, (B) it leaks through everything eventually, (C) still has to be transported around the country and (D) the oil industry loves it, as
they see it as a way to make more money from their oil once petrol and diesel sales drop off.
Here's one source (but I have read quite a few that say similar things):
Yeah I almost never see smokey diesels anymore, only kids that have bought an old 306 and cranked up the fuel pressure. Modern ones are almost
incredibly clean. Even my old 1KZ powered hilux rarely spits smoke unless I'm full throttling it up a hill.

Pretty certain that the harmful pollution from diesels can't been seen. It's definitely there.
I personally look forward to the day they're gone.
It's the PM2.5s and NOx emissions that they worry about (Soot from running too cold/rich, NOx from running too hot/lean). Most modern Ds operate
lean and cool most of the time, only lean and hot when under load. Most of the current literature on 2015 cars shows that Ds emit the same NOx and
1-2% more CO2 in real world driving scenarios, and only 15% more NOx in high load driving which accounts for a very small percentage of the driving
cycle. This is why DPFs and after treatment systems like EGR are vital, but perfectly usable to bring the emissions back in line with petrol. The
vilification of (modern) diesels is mis-placed. If I have a 2 litre modern diesel, and you have a 2.5 litre modern petrol, you're probably
emitting more than me (I don't, I have a 3 litre old diesel that is nearly 30 years old, but it is financially crazy to replace it).

I found that quite interesting, but they are taking just one guy's view, I have no idea what his agenda or biases are, but would be very hesitant
to listen to one individual's view without researching dozens or hundreds more ........
I certainly can't agree with his view on big trucks - despite Tesla's outlandish claim's which it has yet to properly demonstrate in
the real world, & speaking as an electric car owner, so I have some experience, his claim that many big trucks do no more than 250 miles a day,
seems unlikely, but even if true, a 40 ton truck that can do 250 miles on one overnight charge (particularly in depths of winter or in generally
colder climates) is going to need one massive shedload of batteries, so there's your space & payload gone, it's also going to to need
some humungous cables to power it for that overnight charge particularly when parked alongside 50 other similar trucks that all need charging - pretty
sure we're going to need an alternative here
The synthetic fuel thing is also interesting, but surely humungously expensive?
Add in the domestic heating side - I currently pay 1/7 the price of electricity for 1 kW of gas, & his estimate of 4:1 on heat pumps is waaay
optimistic, you're looking at more like 2.5:1 when it gets significantly cold, to say nothing of the inefficiencies of heat pump type CH in older
less well insulated buildings.
I'd say we're a loooong way from any sensible solution yet

Modern diesels are better than old ones but they still chuck out the schmoo. I had to take the egr valve off my old diesel as it wasn't working
properly. It was clogged full of particulates, looked like someone had cast a bbq briquette in the tubing.
They could move away from lithium by moving to sodium batteries but they have worse energy density. Which means more energy hefting round the
batteries....

I did say that this was just one of many articles that I had seen and/or read. He's not alone, although I don't necessarily agree with
everything he says.
I do agree that we're a long way from any easy solutions.
As an aside, It must be said that renewable energy sources don't cause very many environmental disasters... (e.g. Gulf of Mexico oil spill,
Torrey Canyon oil spill, plus many thousands of other catastrophes).

Agreed, but nor does properly managed nuclear - the problem there being disposal of used fuel, which wouldn't actually be a problem if we
didn't have lunatic terrorists roaming the planet.
One major gripe I have with renewables is that instead of putting solar panels on industrial rooves, they are covering perfectly good farmland making
it useless for crops .......

Very true - there are also quite a few desolate ex-industrial sites that could be used - old demolished power stations, chemical plants, and so on.

Kinda the point - the EGR recycles to reduce NOX output and of course it catches soot. Soot goes into the DPF where it is subsequently burned to less
harmfull materials. Same as petrol.
Let's be honest, batteries have inherent problems too and all you're doing is moving the problem away from the point of use, but there are
no current technological improvements likely to make decent power density jumps, especially not in clean forms. Nothing comes for free.

TBH this is because it's not financially viable to run farms anymore, and land costs even of old sites, are huge. However Agrivoltaics are a real
thing and give the positives of both.
sort of on this subject, I keep wondering if the Arabs etc will start sticking vast numbers of solar panels up in the deserts, and use the energy
generated to make synthetic fuels. It would keep them in business as oil production falls (or IF it falls)
I also don't understand why tidal power is not utilised. Set up a number of tidal lagoons around the UK coastline, and we would have a totally
predictable and reliable 24hr source of energy. The costs are not dafy either, there was scheme that went head tio head with teh chinese power station
being built, and over the long term would have been cheaper AND the UK would not be lumbered with the massive decommissioning costs. Not to mention
the stupid idea of having the chinese running a UK nuclear power plant.
Make more sense to just export the power to neighbours.
Tidal isn't done because it turns out it has fairly hefty environmental impacts if done at scale and the costs involved are fairly large for the
geoengineering involved.

Salt water is incredibly corrosive, it's a hostile environment for maintenance workers, the sea is unforgiving and will, eventually, win against
humans.
tfl tested hydrogen buses in north london about 10 years ago, but they had too much difficulty with hills (1 in 15 in places) but we now (and for the
last 3 years!) have battery electric buses.

I'm guessing they were retrofitted gas fed hydrogen like the old school lpg conversions.
Hydrogen makes no sense until the power source for converting water to hydrogen is practically free and entirely renewable.
