Diesel & petrol alternatives? Your thoughts please

Forget electric cars Blue Hydrogen is the future.

I wonder I’d BH will be the other side to EV like Petrol is to Diesel👍🏻🤔

JV, the last time ‘Frank down the pub’ gave me advice it was concerning the face mask I had hanging from my neck. . .He told me Covid-19 was a big con being used by China to make $billions around the World & as soon as we breathe thru the masks we’re infected🤷🏻♂️. I didn’t bother to tell him mine was Brit bought or that I was concerned for his mental health. You may know some real Franks but I’ve never met one👍🏻

Good point, it has proved to be the 1st & only Frank, my one was much easier to spot. I guess some folk attract em🤷🏻♂️

Financially an electric local runabout would be a total waste of time for us. Just checked and it is our Yaris 22nd birthday today. It can't have much longer sadly. We both use it and in a normal year it has typically done 1,500 miles during the 35 weeks that we are home and retired. No idea about last year as we did not go away (just checked about 1,200 last 12 months through our not eating out every week and Welsh Travel restrictions.

Some of us, after four years on this thread, are now getting our previous posts quoted back at us. I'm glad to see progress on here!
There are all sorts of developments in the proverbial pipe line but change is the main one and it might be hard for some to accept but it will happen.

Could well be. Blue Hydrogen seem a much better option for HGVs, buses, trains etc. It could even be the way forward for Motorhomes and tow cars.
Its also being mixed with Natural Gas to reduce carbon emissions in the same way more ethanol is being mixed with petrol. (E5 going to E10).

Err, I obviously need to do some research because my initial thought was-great but now, adding natural gas which is a fossil fuel to Hydrogen that produces moisture in exhaust seems counter intuitive☹️🤔

Sorry, what i meant is hydrogen is already, (in some areas) being introduced to the natural gas supply that is piped to your home. The Nett effect is a reduction in carbon emissions from boilers, fires, etc.
Its being introduced at a level that can be safely burnt by all existing appliances, If it was to be introduced at a higher concentration then modifications to burners would be required similar to when natural gas replaced town / coal gas in the sixty's.
Sorry for the confusion.
Edit
Clearly a perspective from a producer, but informative non the less.

Good to be sceptical Rocky. Blue Hydrogen is hydrogen produced using the Methane Steam reformation process (which on its own is grey hydrogen), and adds carbon capture and storage to it (to make it blue). So far it's a concept being pushed by the oil companies as a "green" energy solution. But is uses natural gas and energy to produce, and more energy to provide the capture and storage solution.

Green hydrogen (hydrogen made from renewable electricty by electrolysis) is truly zero carbon, but is about 30% efficient from source to wheel compared to 70% with battery electric for the same driven distance, so is kind of expensive.
Essentially - you pay a very large amount for the perceived convenience of hydrogen as a fuel.
There is a great podcast here on the subject, (Fully charged) hosted by Robbert Llewelyn, (Kryton from Red dwarf, and Scrapheap)

Hydrogen is one of the options being examined by the railway companies. The one drawback in use is storage , as to make it viable is the very High pressure it has to be stored at to give any sort of miles per fill up , as the same with the bulk storage tanks ,

UK peak consumption has dropped over time, the high point was in 2005 and we are down over 10% since then.
They have built new power stations since that time - mostly wind turines, but mainly, our consumption has dropped significantly.

Personally, I think for shipping and rail where non-direct electric overhead is not viable Green hydrogen via hydrogen fuel cell (HFC)is a good alternative to internal combustion engine (ICE).
Essentially the use of hydrogen as a fuel is a form of convenience. Whether that be weight and energy density over battery (for aircraft or shipping or very long distance trains and trucks) or fuelling speed (sport - think F1 racing or other limited use cases) or transport beyond the established electricity grid (plant machinery, some forms of agriculture). The penalty for the convenience is cost (maybe 3 or more times the raw electricity cost).
All other things being equal (cost of a new car, supply of the fuel (Electricity or H2), availability of refuelling), I find it really hard to imagine that kind of cost barrier being overcome for the "ordinary" public.

Unfortunately the problem with statistics is that thes days they make (fiddle) the figures to show what they want you to see. I worked for 30 years at BT now Openreach. In the later years when the bosses came from university and not the shop floor and figures mattered. They would doctor them to make things look better.

It’s a good job that in my days looking for a job cv’s where unheard of and you went for an interview. I wouldn’t be able to invent enough lies to get a job.In later years you had to have at least 5 GCSE’s to do the job I did. All I got was the cane at least twice a week.

I bet Merve Gaskin with his Toyota running on recycled chip fat is feeling pretty complacent. Economical fuel with security of supply well into the future unless eating chips gets banned on ecological grounds.

I’m not an expert, in fact I just read what experts say W, they say blue hydrogen is a crock🤷🏻♂️. It’s something the fossil fuel industry is peddling. The problem is-it actually creates more CO2 than diesel & petrol☹️.

One of the reasons we opted for our EV was the low running cost. Renewable electricity has a lot going for it cost wise. OH did a cost analysis of hydrogen and it was as expensive as the present fossil fuels. So no savings except the absence of polluting emissions...incidentally a trip on the holiday run A30 in our diesel m/h made us realise how noisy and polluting we all are at present. It can't go on like this. Our SW 28C temps today could be 40+ C in the not too distant future.

It's OK, we'll be migrating to Scotland for our hols where its both cooler and less crowded.
