3 phase domestic supply

[John-SJW]

I watched this vid on Youtube. Interesting. They have 3 phase supplies. Does anyone know the cost of upgrading from a single to a 3 phase domestic supply?

What upgrades do you expect the local network infrastructure to need? It's not all about power stations. You should also factor in the large take up of electric cooking and heating, ie. air source heat pumps mainly.

You can't seriously expect PV to take up this amount of slack in the UK, where we often don't see direct sunlight for days at a time. Yes it may happen in time, but not in the timeframe you seem to be expecting.

Look back on the thread you will see a post by me linked to Fully Charged who interview a top man at National Grid. They say they do not need any more power generation to cope with the coming EVs, etc. The secret is storage of electricity, or energy to make it. Look at it, very interesting. Do not reply until you have looked at it.

Look at my post and you will see I'm not talking about power generation.

The local infrastructure is already creaking and relies heavily on diversity.

Think it was davesparks that brought if up, how do you cope with electric car charging at home if you don't have a car parking space? good thought.

Highview Power are building a liquid air battery in the UK. The world’s biggest Liquid Air Battery. These are being used for grid storage, to balance the grid and store excess electricity. The battery has these characteristics:

• The size of the battery is 250 MWh.
• It can delivery up to 50 MW of power. which translates to five hours at full power, if the battery is full.
• If it was already working, it would be the ninth biggest battery of all types, except for pumped storage, in the world.
• It will be double the size of the largest chemical battery, which was built by Tesla in South Australia.

The same we do now. Go to a charging station. They are everywhere. The south east has more EV charging points that petrol stations.

National Grid say they can cope. They will not upgrade the distribution network unless it needs it.

That's only one piece of the puzzle, the national grid company are only concerned with the national grid and its capacity, which may well be OK for all these chargers.

What you are ignoring is the DNO networks which are in nowhere near as good a condition.
DNO networks are, in some areas, made up of cables and equipment over 100 years old designed when all you had in a house was a few lights and sockets.
Also the effects of harmonics from the massive increase in electronic loads are causing damage to substation transformers which is only going to get worse if everyone has these car chargers installed.

Does it? How are you counting these? Can you provide some data and an explanation of how you are defining petrol station and charging point for this?
A lot of motorway services have one petrol station and 20+ charging points so it is very biased to count number of points versus number of stations.

You would need to talk to your local DNO. it would depend on where the nearest 3 phase was and work involved in getting it to your property.

This is the introductory paragraph.

Researchers are now simulating how the energy transition can be as successful and cost-effective as possible. As part of the simulation, they are also calculating how much hydrogen will be needed and where it could come from. In Germany, a recent study by Fraunhofer ISE showed that the cost is so low that the nation could gift itself the energy transition as a Christmas present.

The article makes these and many other points:

• Hydrogen is ideal to produce process heat about five hundred degrees centigrade.
• Hydrogen can be used to power some cars, trucks, trains, ships, and aircraft
• In Germany ten million cars could be powered by hydrogen, as opposed to forty million by batteries.
• Consumer choice will play a big part in how much hydrogen is needed.

It is very much a must-read article.

Do wish some of you read links and at least do a simple Google before typing. 18 months ago EV charging points overtook petrol stations. That is not including home charging:

An Hitachi battery train. 10-15 mins charge time, or charged when under overhead wires. Can run on overhead wires or battery when there are no wires. Batteries, which are the current types, last 10 years. The batteries will go to grid storage when renewed, with obviously superior new solid state sets.

There will need to be hundreds (or even thousands) of times the number of charging points, than the current number of fuel pumps.

Fast charging is relative and doesn't compare to the couple of minutes required to fill a tank with petrol or diesel. While fast charging points are available, they only represent a small percentage of the total number of currently available chargers.

It is beyond doubt that EVs solve some of the problems we're facing, but I simply do not view them as anything more than a stop gap, with hydrogen being a much more viable long term option.

 

[John-SJW]

Hydrogen fuel cells are viewed for large vehicles: ships, trains, trucks and even buses. Batteries for smaller vehicles like cars. Germany already has fare paying hydrogen trains in operation.

Batteries will be used for trains where there is a mixture of electrified and unelectrified track. Merseyrail metro at Liverpool have a new Swiss train fleet which can take batteries and run on 3rd rail or wires. They are to use them to extend the service onto unelectrified track in a number of peripheral locations.

Hydrogen is out as combustible fuels are precluded from the Liverpool & Birkenhead underground sections. There is a plan to extend the metro to Skelmerdale, making it feasible because the cost of electrification is omitted. Then trains can run from the centre of Liverpool's underground section to Skelmersdale. There is also in that area to be a hydrogen trial on the Liverpool to Chester line via Runcorn. Train maker Alstom are on the line, as is a local oil refinery for the hydrogen gas. Covid delayed it.

Batteries be a part of the solution, but EV cars are here to stay. Once the solid state batteries are here they will be firmly fixed. Home chargers and fast chargers everywhere then they are solid in the market.

It is viewed that we will charge EVs like we charge smart phones, drip charging as we go. Go to the supermarket then plug in for free, getting maybe 10 miles of range. Go home, then plug in. Go to work then plug in, maybe for free getting lots of miles over 9 hours. Fast charging on major roads.

Even if some chargers are not that fast, they will give enough energy in the battery to get you around in normal circumstances.

Hydrogen is a wonderful fuel, its just a shame that the vast majority of our hydrogen supply currently comes from fossil fuels and creates just as much pollution being made as burning the fossil fuels would for energy.

None of this 'plugging in for free' will be free, we will be paying for it one way or another. The cost may be hidden in increases in the price of your shopping at the supermarket, but you will still be paying for it.

For a supermarket car park to be fully equipped with car chargers they will need quite a large electricity supply capacity.
and at busy times it will be quite highly loaded, unless intelligent load control is incorporated in the whole system, but that will then lead to none of the cars getting very much charge whilst they are there.

Read that article about Germany and hydrogen. Very good.

The grid pay companies to use electricity as at times they produce too much. In these circumstances, and overnight, they can produce hydrogen, to sell or use to produce electricity in peak demand. This balances the grid, the holy grail for the grid operators.

Introduction:

A 20-foot container sized battery that can charge four electric cars simultaneously has been safely delivered to Portsmouth International Port in the UK this week as part of the Port Energy Systems Optimization project.

It looks like another case of battery-to-battery transfer to fast-charge one or more battery-powered vehicles or trains. Charge the container overnight then deliver it to a station for the day. Sounds like an interim solution.

Electric Cars are the work of the devil. They were tolerated when they were used to deliver milk early in the morning but now they pose a serious threat to the world as we know it.
I fear the world where civil unrest breaks out and new neighbour disputes emerge about whose turn it is the charge up the EV. Dark days ahead in more ways than one.

 

[John-SJW]

plugsandsparks, you really should find out before typing.

 

[plugsandsparks]

Sadly, i am at the sharp end on the last few miles of electrical energy distribution, install EV charging points and deal with clients who dare to ask for more KVA from their energy provider. I dont need to read anything, i live it
Oh and i recently quoted for a Super charger.... do YOU know how much these things cost ? and what is involved ? - Its eye watering....
Oh by the way tesla charge 24ppkwh, thats how they are paying for the superchargers.
Stop reading !!, by a Tesla and find out for yourself the reality of your dreams

Well something will have to change with our love affair with fossil fuels, it’s polluting the planet and is running out.

Seems we have approx 50 years left for oil & gas and 150 years left for coal. Perhaps our grandchildren will be driving around in steam engines

Ev cars seem initially very expensive. There’s a couple of ev Jags near me. They start about 70k. Cheapest ev are 30k. I normally buy a newish car every 5 years or so, will my sons be able to afford that.

The prices will have to come down, we’ll have be able to go to an Electrical station, and charge up in a few minutes. As said not everyone has a drive. There’s plans for pavement parking to stop, so lead’s across paths won’t happen.

The combustion engine is nearing its end, not in my lifetime, nor my children, but will happen for my grandchildren.
