Hydrogen may not be feasible now but going to look cheap with electric prices then and EOL costs to those superposed to green batteries...NO EV cars will not be here in 30 years it will be something else we don't have with a combustion engine yet, aircraft cant fly on batteries either, nor can trucks to any super miles they have to cover with Batteries plus pulling power, The combustion is still king even if its not four star/diesel running on them in the future, its something we don yet know what it is, EVS are NOT the answer
A few things to address there ...

A huge percentage of the UK's current power use is actually taken up with refining fossil fuels. In the UK alone, oil refineries use 5620 GWh of electricity per annum. That's the consumption required just to get the fuel as far as the pumps. Clearly, a move to EVs would result in a drastic FALL in this particular area of demand on the grid. The net effect is that if every ICE car were to be replaced by an EV, the overall increase in demand on the grid would be something in the order of 8%.

It's a misconception to think that everybody with an EV would arrive home from work every day and plug it in to charge straight away, crashing the grid around 6pm. Obviously there are plenty of outliers, but the average driver in the UK covers just over 7000 miles a year, or about 21 miles per day - with today's mid-range EVs (let alone the longer range ones that are in the pipeline a couple of years from now), this would mean one overnight charge every week to ten days. Not every day.

You reckon the era of cheap electricity is a goner? On the contrary, the cost of offshore wind production is continuing to fall and is now below the overall current market price. Good news for us all, as it will see our electricity bills reduce.

You reckon that trucks aren't capable of running on electricity? Best let Amazon know that, seeing as they've ordered 100000 of them from Rivian. For larger scale HGVs, you may be interested in checking the specs of the Tesla Semi. 500 miles on a single charge, 30 minutes to add a further 400 miles of range, lower running costs than a diesel HGV and better pulling power, especially uphill.

"End" of life for batteries in vehicles is deemed to be when they fall below 70% capacity. So today's Kia e-Soul, for example, will still have a combined range of 160 miles on a single charge by the time it will have "failed". Capacity is very easy to measure and the data thus far indicates that for EVs produced in the past 5-6 years, batteries can be expected to last some 900,000 miles. The rest of the car will be scrap long before the battery.

But this doesn't mean so-called "end of life" EV batteries actually get scrapped along with the rest of the car, it means they become an asset which gets repurposed for commercial and domestic power storage. Don't forget that a 50kWh battery whose capacity has gradually dropped to 35kWh over the years will still be capable of providing all the average UK household's power requirements for three days solid. As this becomes more widespread, it will help greatly with "smoothing out" the peaks & troughs of grid demand. The main reason night rate electricity is cheaper is because there's less demand at night, but it's too costly to ramp production up and down. With the adoption of battery storage, power produced overnight can be stored on-site and used during the day, when demand is at is peak.

In short, EVs ARE the answer!
