Hybrid motorhomes

[colinm]

We can't meet our own demands now without buying from France never mind in the future and they have signed to buy more. As fisherman said we need at least 3 Nuclear plants it we are not going to be held to ransom. They didn't put all them smart meters in for no reason, they will be able to have planned power cuts to homes without harming businesses.

As I type this the UK has around 20GW of spare capacity, but we have a net import of around 2GW (we also export), in winter these figures change a lot, but does it matter where we buy in electricity? after all we also buy in oil and gas.

Sorry Derek, but my post was based on information given out by the government.
It’s reckoned that we would need 3 nuclear power stations to power all of the electric vehicles,

Also the fact that most people would want to charge their vehicles at the same time would put great strain on the grid, which needs to be upgraded to handle this. Hydrogen fuel cell avoids all of these issues. But it still requires batteries

Some of what you say is just repeating what I said. Your 3 nuclear power stations is an estimate it could be 6 (just another estimate from a reputable source.) as I also said hydrolysis reduces strain on the grid.
What you did not go on to deal with is all the other fossil fuel burning we do . Gas for the grid, and for home heating must be replaced, from non fossil sources. There is no point replacing internal combustion cars and not going on to replacing gas use too.

Why is there no point. If you believe, for whatever reason, we should reduce our use of fossil fuels, then any reduction is an improvement.

I watched a really good programme on YouTube about an alternative. Hydrogen. It also has its problems though. My view on electric is its one of the most polluting fuels that can possibly be used given what it takes to mine the metals. process them,transport them then re process when they stop working. I used to work on big diesel engines so from what I see we have to change but to what is the answer

Electricity, Hydrogen, Diesel with Ad Blue. Hybrids Decisions decisions. Or we all walk, cycle or use space hoppers. That said, from what ive just experienced using our rail system, a space hopper doesn't seem such a bad idea. If we invested in top quality public transport it would make a difference like other countries do. But as its Britain and we've flogged off all our infrastructure to profiteering corporations, what we get is do it for the cheapest you can do and make as much money as you can.

Any reduction is an improvement, there is a point to that alone yes. However Will that reduction be enough? My understanding is we all must leave all fossil fuels in the ground as soon as possible. Vicious cycles are already showing that global predictive modelling of climate change was showing only part of the problem.

They are working on a salt silicate battery,when they crack that we are home and dry,so im thinking of buying as many beaches as i can then sell the mining rights,fact is the crown own most of the shore line.:king:

If we in such a great place capacity wise. Why did the UK have to import a total of 21.4 TWh [terawatt hours] and only manage to export a total of 2.2 TWh 1.6 of that to Ireland who in turn managed to export 1.7TWh back to the UK in 2018. When UK generation fell to its lowest since 1994 and has been on the decline since 2005.
Do you want the EU to be able to turn your lights off if they have partial control of the electricity supply or dictate price.

Could be of interest to some GB Fuel type power generation production

So if you're caught nicking the sand with your bucket and spade the
Queen can land you with an A Salt and Battery Charge Trev.

 

[martinmartin]

Well its going to happen as the paperwork is sorted in law,as for trucks the yanks have some with 2000hp lecy motor covering a huge millage which when the driver has his break it can be charged to 80%,remember we have 20 years to get it right,and as for power why do you think there are so many wind farms and water turbines getting build all around the country.
Never mind the global warming due to burning fos fuels,the polar caps are melting at a very fast rate due to this,we must stop now and take action before its to late.:scared:

Manmade global warming is another nonsense trev,ten thousand years ago Britain was under half a kilometre of ice, the earth warms and cools naturally.

No! Don't go upsetting people with facts like that. Don't you know temperature rises can only be valid if they occur after the mini ice age, and please don't go mentioning the period known as the Younger Dryas, :lol-053:

Of course we have to rely less on coal and gas fired power stations, that is stating the obvious. Hence the massive investment on renewable sources. But to suggest that we could charge millions of electric vehicles with no additional output is bonkers. Obviously this additional power has to come from somewhere, what’s up for debate is from where and how much. Also it’s not my estimate of three nuclear power stations I leave such calculations to those who know best. Also I did not go into discuss the benefits of many things to numerous to name, because I thought this thread was discussing alternative means of powering vehicles.

It won't happen, they'll have you believe in perpetual motion next. I do believe they're working on shrinking quadrillions of positively charged lepricorn into a working battery.

True but they do have small torch battery cells working,they hold 5 times the charge of normal batterys and can be fast charged,mind you getting from a lab to production may take many years.

For the vast majority of the time we don't need the cross channel links for capacity purposes, we use them to offset CO2, the alternative would be to import more gas or fire up the coal stations.

If in future years millions of us wish to charge our vehicles from the national grid after work we will need both additional capacity and improvements in the network to cope with this demand. According to the experts we will require 3 nuclear power stations and possibly more as more of us switch to electric. Due to the fact that renewables are unreliable and that currently we cannot store vast amounts of electricity this can only reliably be facilitated by non renewable sources.
Currently the grid struggles with supply when certain tv programmes are running, due to the fact that many switch on their kettles to make a hot drink. Just think what would happen with current levels of supply if millions of us started to charge our vehicles.

Only last week we had a million losing their supply due to two power stations shutting down, a gas turbine plant, and an a coastal wind farm this resulted in only a five percent drop in output, which we could not cope with. There are times when the grid struggles to supply us, and without new power plants coming in line in the next few years, we will see an increase of events like last week. And all of this without millions trying to charge large capacity vehicles.

Yes we will need more reliable supplies than wind which sometimes is pretty useless, and yes we will need extra capacity if EV's become dominant.

Other than that the events you describe are nothing to do with overall capacity, they are all about fluctuations in demand or supply, last week when a million people lost power there was huge reserves of capacity, but it wasn't fired up ready to go.

 

[trevskoda]

They wont use power stations,new power will be from wind wave & solar ,my mate has a vw lecy and charges from his solar roof panels with no bother in summer.
So tide wave power will make up once they get the finger out and as we all know with our gov it will be a last min panic as normal.:rolleyes2:

There are possibilities of flattening wind variability and coping with demand spikes with lithium battery banks, Now these are cheaper. In fact plugged in electric cars may be used for this purpose if supply technology gets smart enough. We surely dhould be offered cheaper electricity if we accept charging offpeak.

So you are going against the advice given by experts that we will need additional supply to cope with the demand. The fact is currently we don’t have sufficient supply to deal with what may lie ahead. I am not giving you my opinion, but the opinion of those charged with such issues. If you reckon that we can simply drum up all of this additional electricity without increasing supply then that is fine by me.
