Every cloud has a silver lining.

From Energy Newsline:

British drivers that took the plunge to go green and pick up an electric vehicle (EV) may now bear the brunt of sky-high energy prices from October.

Ofgem’s announcement that the price cap will rise to £3,459 will be reflected in the cost of driving an EV, with the price of electricity almost doubling from 28p per KWh to 52p. This is while petrol prices have dropped in recent weeks to an average of £1.70 per litre.

A study by the RAC has revealed the differences of running an EV with its petrol equivalent in a new study. Drivers of a Jaguar i-Pace – the company’s electric SUV model – would expect to pay £99 more to travel the same distance as the petrol version; a Jaguar f-Pace.

There's Life in the Internal Combustion Engine for years yet.

 The thing about ICE - petrol or diesel - is that they are an extremely ingenious way of of converting high energy density fuel into a rotary motion.  They are also very cheap to make and there is a whole infrastructure to support them.  They are also very light and nowadays relatively fuel efficient and clean burning.  Small turbo petrol engines are astonishing.  There are 1.2L capacity engines now used where in earlier times you's expect to see at least 2.0L .

If you want low fuel use efficient vehicles among your greatest enemies is weight.  The more weight you add the more weight you need to add.  Thusly by adding a one tonne battery pack to a vehicle you need to proportionally increase the strength of the structure, bigger brakes, heavier duty suspension and so on.  So all things being equal the lighter you make a vehicle the better.  This applies to all classes of vehicle and road vehicles.

So adding batteries to cars is a bit of blind alley because they are very heavy, have low energy density, very expensive (and as they use lots of rare minerals I very much doubt that they going to get cheaper), they take ages to re-charge (for which there is no infrastructure) and they have a limited life (a recent study said about 5 to 8 years / 80,000 kilometers - at which point the vehicle is effectively scrap value). 

An alternative to batteries is hydrogen fuel cells.  But these are also expensive to make and rather delicate.

Luckily along comes that Damn'd market thing. Given that we are being told (albeit erroneously) that CO2 is evil people have got beavering away - some of them in sheds (a very good thing - lots of good stuff comes out of sheds). And there are emerging some very likely superior to batteries ideas.

Exhibit 1. https://www.youtube.com/watch?v=19Q7nAYjAJY; (I have also heard that Jag is working on the same thing).

An ICE powered by hydrogen. Seems like a plan. The emissions, the by-product of combustion is water. As to infrastructure. You can imaging one of those roll on roll off container lorries delivering a contained of hydrogen very easily to an existing forecourt.

Exhibit 2. https://www.connaughtmotorcompany.uk/ This outfit has a low revving (i.e. slow speed diesel) on the stocks which is clean.

Exhibit 3. https://www.formula1.com/en/latest/article.fia-deliver-first-barrels-of-sustainable-fuel-to-f1-power-unit-manufacturers.7G1Jgfox1YTVzjhhzZxNSt.html - racing improving the breed.

Exhibit 4a. https://www.nationalgeographic.com/science/article/carbon-engineering-liquid-fuel-carbon-capture-neutral-science

Exhibit 4b. https://sustainingourworld.com/2019/09/19/3-ways-to-make-liquid-fuel-from-carbon-dioxide/

Exhibit 5. I was speaking with someone who's son works in F1 as a power train engineer. One of the F1 teams is developing a two stroke petrol engine that revs to 24,000 (!) and is clean.

It's going to be easy to switch a petrol tank to an hydrogen tank (many people have already converted V8 Range Rovers to LPG) and crucially we can make LIGHT CARS (heavy cars being a particular hobby horse of mine). As long as the ecomentalist watermelons and the bonkers government can be nailed down the ICE is clearly not dead.

How is this going to Happen?

Stupidity from Shapps via the BBC


Last week, the government sparked industry concern after bringing the date forward from 2040 to 2035 in a bid to hit zero-carbon emission targets.

But Mr Shapps told BBC Radio 5 live it would happen by 2035, "or even 2032," adding there would be consultation.

Of course, the consultation will mean that every green sockpuppet paid for by the government will file returns because they know exactly where to go, so it'll be a consultation in favour.

But aside from that, how will it even happen?

For one thing, we don't have the cars. We've got the Nissan Leaf, the Tesla, a few really expensive cars, but very few are being bought. They're also only tackling smaller cars, and for people needing a bit of offroad or towing power, they aren't there. People just don't like the range. Or the cost.

But even if someone creates a Ford Mondeo size car with decent range at a good price in 3 years, are most people going to rush out to buy them, or are they going to wait and see what problems occur? Maybe that battery won't be good in 5 years. It's not like there's huge upsides. OK, cheaper to run, but petrol's a pretty small cost of owning a new car. Plus, for a while, it's going to still be difficult to fill the car.

So for many years after, the dominant demand will still be for petrol because of charging. Over time, as it's adopted more, it might change, but by 2032, I seriously doubt we'll have seen a changeover.

And we simply don't have the power network to charge every car, and the lead time for nuclear power is far beyond a decade.
