Will Ev's Become The Betamax ?

[youngmafbog]

JCB have created a hydrogen digger. A new ICE not an old one tinkered about with but one that doesn't give out nitrogen.

I've raised similar threads on here over the years but am usually derided by the usual. But for me hydrogen is the way to go, at least for the immediate future.

Thoughts?

probably the most pressing problem with using hydrogen as a fuel is one of storage. the volume of hydrogen required to produce the same amount of chemical energy as fossil fuel ranges from 5-10 times, depending on the storage pressure; that with the most storage capacity requires specialist cryogenic containers, whilst fossil fuels are contained in simple unpressurised receptacles.

in theory, hydrogen could be used in place of the domestic gas supply. in practice, the delivery pressure required to make it effective would mean replacing the entire gas supply network. (early tests on the existing system in the Tyneside region revealed most of the hydrogen just leaks away).

There is work to be done mushroom but its no insurmountable and the tech is already there, just needs the will to do it. Worcester Bosh have already developed a boiler. It is certainly more cost effective then Johnsons heat pumps and it will work in this country whereas the pumps generally wont.

Replacing the network would be a pain but gas pipes are often replaced so just a bit more care. Remember when we switched from coal gas?

Anyway, back to the EV question....

I've always argued that electricty is just not portable enough, so there is no future for EVs. Now, however, you can buy a "reserve can" for EVs; for only £800 or £50/month rental you can use this:

I still think there's no long-term future for EVs.

YMB: ||//we'd need a way of producing hydrogen without lecky.//

Why? As per the article we can have 'free' electricity from very clean means i.e. Solar and Wind. At night the electricity from these cannot be saved so is already 'wasted' so generate the hydrogen at night.|| - ok but with the increasing numbers of lecky jam jars that overnight capacity will have ever more competitors and at the moment EPVs are winning in the race away from Petrol/diesel. It's not "free" now something is used to generate it, and it will soon start to get expensive. Why would you use electricity to create hydrogen when you could use it directly? I also see a huge problem with generating enough power for ever increasing EPVs. We struggle with all the kettles in the middle of corrie, what's going to happen when millions of EPVs come on line?

National Grid's current answer to the kettle/Corrie conundrum, the Dinorwic Electric Mountain, is in trouble........

Personally I'd make all the soaps available in the middle of the night only. I have never understood the popularity of such televisual dross but hey ho!

How many people watch things like Corrie "live" now? I don't watch anything as it's broadcast. I record everything and watch it when convenient (skipping through the adverts and ditching anything that looks, after five minutes, to be dross). I think the "Corrie Kettle" problem must be very much less serious than it once was.

[ToraToraTora]

well going by the spike at the ad break judge, still quite a lot. Like you I hardly ever watch anything as it's broadcast these days but many do.

Then my ghast has never been so flabbered! :-)
