I remember many decades ago when the first rechargeable drills came out and my old man bought one. It was a bit of a novelty. A dozen holes through some roofing iron for some rivets and the battery was dead. Fast forward to now and you can get nearly every power tool in a rechargeable form and they work as well as or some even better than their plug in or pneumatic versions. The technological change from NiCad to Lithium batteries made the difference and the newest lithium battery tech is improving the capabilities every year.
My accountant has a Tesla, which his wife uses as she clocks up a lot of kms between university campuses as a project manager. 70,000 km a year and no major issues and no major servicing required. Uni has free charging so no fuel cost either

Tesla has a battery day recently, which can be found online, detailing some of the advances they were making in battery tech. The result of these changes would lead to cheaper, cooler running and more energy dense batteries. And while Tesla is pushing their tech Toyota, LG, Siemens et al are all developing their battery and renewable tech with hydrogen being rapidly developed.
Druid, don't worry about hydrogen storage, if hydrogen escapes it rises immediately and dissipates. However when petrol leaks it just lies around waiting for a spark ...
Like the advance of mobile phones, technology can lead to exponential advances which can change habits and the daily tools and vehicles we use. In Australia some of our Universities have developed and licensed a lot the technology that is now producing cheap solar PV panels which are being installed all over the world including the UK. They even produce power when it's cloudy. In Australia over 21 percent of households have rooftop solar panels and many produce more power than they use and feed the excess back to the grid. Large scale batteries are also being used here to balance power loads rather than peaking generators which is saving millions in peak power costs.
The change from petrol/diesel vehicles to electric/hydrogen vehicles is a massive opportunity for employment and product development throughout every country just as the T Model Ford made a car affordable for the masses. Just like the rollout of faster internet was in many countries, (especially Australia), a patchy and political process, once it finally worked it has become indispensable to how we do business especially with COVID lockdowns. I can't wait for affordable, electric earthmoving equipment with all day battery/hydrogen capability. Just think of how many moving parts and fragile emission control tech in modern diesels is going to be replaced with a simple electric motor with just a couple of durable moving parts.
Like any new products the first ones will have higher costs and some limitations but once manufacturing scale combined with competitive product development gets going electric tech will make fossil fuel machinery seem antiquated and high maintenance. I love going to steam rallies and other antique equipment field days and seeing what it took to run a workshop before electricity. A large single steam or oil engine had to be started, after all the preparatory steps such as building steam or heating a hot bulb had been done, and then it powered a live shaft through the workshop which had leather flat belts to drill presses, lathes, hammers and other tools. Now we flick a switch and we're away and the electric equipment will run for years with minimal maintenance.
However like every change, we see the soul in the old tech, such as the fascination for the steam era. Soon we'll be looking back at the diesel era and fondly remembering the deafening scream of a Detroit 2 stroke diesel as much as we remember a favourite piece of music from the past
