10 years down the line, problem with ESB infrastructure at home??

Your missing solar panels and batteries and smart load management and wfh and some cars being there all day and cars not always needing to be charged at the same time. Alternate days lots of range.

You're missing alot tbh.

Every typical family will have a house and 2 cars.

Sounds great.

Where do I sign up ?

People won’t be charging 100kwh batteries from empty to full. We have capacity for 600,000 cars with out changing our supply 600,000 just brings out night load in line with our day load.

( based on 300,000 charging @7kw for 4 hours, and another 300,000 for another 4 hours)

19bn is being spent developing the grid.

35 does seem to be the much muted figure, but very few, if anyone has actually agreed to it yet, im not aware of it anyway, theres clearly a gigantic squeeze happening now, to try phase out ice, but ev's may not be the ultimate answer, its good to see some are not giving up on hydrogen, as we re gonna need everything to try get out of fossil fuels....

...the disturbing fact of all of this is, governments dont seem to be able to understand their ev plan simply wont work as is, as we re clearly hitting some major obstacles in regards the ultimate cost of living and borrowing households can maintain, in order to move to a complete ev model, significant amount of private debt/borrowing is required, but a significant proportion of the population is now simply over indebted as is, the majority of which is based in them trying to meet their property needs, so borrowing even more for a relatively new ev simply isnt viable for many, probably most, and then of course theres all the other ev obstacles to overcome, i.e. long charge times, battery deg etc etc, many are simply just defaulting to ice, as these obstacles are simply too much to take on....

clearly our property model is deeply flawed, and will collapse, again, its already in a deeply dysfunctional state, this all plays into the ev plan, helping it to fail to....

..another major failure in this plan is towards public transport, in particular rail, in order for us to truly move over to an ev model, countries will also need advanced rail networks, we clearly dont have this, and by the looks of it, we may never have, again, this is a failure at government level, so....

The thing is very few households would need to charge both to full every night. We have 2 ev's in our house. Both used every day. I charge up when mine gets to about 20% but usually the other one doesn't need to charge that night so is grand. In fact we don't have a car charging every night at all during the week. Usually 2 nights or maybe 3 if there's bigger journeys happening.

You're also not factoring in if people have access to chargers at work and if these are being used.

Won’t need to worry about this when hydrogen powered cars take over, we already have the infrastructure in place, in regards to fuel stations, a few upgrades might suffice there, and the whole way the world goes about filling up their car already will still be the same.

electric isn’t the future , it’s part of the future for sure, but not it.

Hydrogen does not make sense for cars. There’s use losses converting hydrogen to electricity

where do you think hydrogen will come from? That’s right we use electricity, so if we use hydrogen we’ll need more electricity

Ask Shell why they are closing all their Hydrogen stations.

Tbf all things considered hydrogen make sense as an energy store for areas that may produce excess energy that's not readily transferable. E.g high wind areas west and north west or tidal. They are already doing similar use cases in the Orkneys.

energy storage in renewable space is multi faceted and battery's cannot make up the single answer. Turlough hill type schemes, hydrogen conversion, mine shafts. Many options locally suited to generation and environment conditions. The future is multi layered.

The main problem with hydrogen is the storage of it in the vehicle. The most recent mirai from Toyota has a 400mi range, which is comparable to a Model S long range. So the range is ok, equivalent to the best of the EVs.

The drawback though is that it only has 400mi of range and can only be charged at a station, while an EV can be charged at home. It is only home charging that makes limited range tolerable. Unless Toyota can start to pack ICE-like ranges into their hydrogen cars, they will remain the EVs poor relation.

Don't forget a recent study found the average commute in Ireland was something between 20 and 30km.

No need to be charging every night. Even in 2024 with 58kwh or 77kwh, you don't need to he charging every night.

hydrogens not going to be a thing, no matter how much you think it is.

its too inefficent, too expensive, and its already failed everywhere its been trialed.

The continuous supply rating for most houses is 50 amps, so with 2 chargers each car can draw 25 amps constantly, say 5kW giving about 100km range every 4 hours to both cars. Now if you do add in dishwasher, washing machine, hot water for showers and try to shorten all that into a 2 hour window for lowest price you may have an issue. Even then most commutes would be covered. Those with a big night draw will probably pick plans that give 4 or 6 hour windows of low pricing time. I know I consume more total power at night than all day consumed.

I think the ESB infrastructure will cope. Indeed many new houses have heat pumps and some demand a bigger than normal supply as a result.

Long term we may move like the UK with electricity prices changing every 3 minutes and smart car chargers turning on and off to maximise the cheap minutes and get max power from wind, or when there is excess nuclear from UK at night. I only need to half fill my EV once a week so not a massive impact.
