Hummer Electric 4x4 with claimed 350mile range

Everyone will have an EV within the next 5 years - 3 months of ownership of my first and would never go back to a petrol station with anything that does significant miles !

they are brilliant and 4x4 farm trucks that rarely do big miles, need torque to tow / 4x4 and come home every night are the perfect application
Unless hydrogen production and distribution takes off, could end with a VHS - Beta Max stand off. Change is coming just depends on which side to bet.
The electric vehicle recharge network is currently patchy in some places and would require significant investment if all vehicles were to change to batteries to cope with demand but with a bit of will the hydrogen scheme could prove to be much more effective without the wait to recharge.

I fancy finding an old Outlander PHEV, chucking away the engine, filling the engine bay with batteries. Might even convert to a pickup if cheap enough.

electric has established already as the “vhs” now i think

charger infrastructure is a red herring imo for most when range is 300-350 miles - how many regularly do that in a day ? truth is you change at home overnight or at work while at the office or factory etc

Unfortunately hydrogen has problems, mainly in the energy cost of getting from renewable electricity to power at the vehicle wheels. It could be used to soak up excess electricity on very windy or sunny days, when the cost is immaterial, but otherwise battery power at 69% efficiency is much better than hydrogen, at best 23% efficiency

What is the runnin cost like compared to buyin fuel? Also what is the difference in purchase price?

No denial that hydrogen production is energy intensive but it is storable for the days when the sun doesn't shine and the winds not blowing. Currently network has to rely on fossil fuels or nuclear to provide base load for these cases. Hydro schemes could be used as buffers but expensive to build and getting approvals to build will rule this out.

Electric car via battery technology is well advanced as this has been the preferred route for a while, whether wholesale change to electric is feasible for the whole world i don't know as production of lithium for batteries is energy intensive and whether there is enough raw materials to produce required forecast demand is available.

Long term even with its inefficiencies hydrogen is a more sustainable route to take as lithium extraction is energy intensive in the first place and the battery life has also to be taken into account in a holistic manner not just the headline operating use.
Do like the idea of the Tesla power wall for homes rather than a massive inefficient transmission network for renewables, this for me is a better use of the worlds lithium and would enable a micro grid to be established giving small generation schemes figures that stack up without subsidies.

For me could see a whole new economy being built on hydrogen as we have the wind and the water in this country to make it work which would benefit society, problem being government will try and get the cheapest option not necessarily the best whatever that becomes.

I am less concerned about lithium than the cobalt and nickel, as lithium reserves are quite large, and it is infinitely recyclable. Battery life is good at over 400,000 miles in many instances in a car, with a subsequent long life in home storage battery. Tesla and others are getting close to eliminating cobalt, and there are big solid state battery developments in the pipeline

"1,000bhp, 11,500lb ft of torque"

jesus christ thats immense, and being a motor its instant aswell not like a conventional engine, i hope its got strong half shafts :ROFLMAO:

with the capabilities of these new vehicles it makes you wonder why everyone has waited so long to crack on with them...

That 11500 foot pounds of torques is grounded torques ie- after gearing
 
Suppose 50% of road vehicles were electric, by how much will electric power generation need to increase?

I'm not expert but the correct amount is Fudge-loads [note capital F].

Current UK electricity consumption is around 300TWh per year, petroleum product demand is about 70 million tonnes (2019) and natural gas about 875TWh per year (2019). Of the petroleum demand 25 million tonnes was in diesel.

Here is the link to this data, which is generated annually by the government. https://assets.publishing.service.g..._data/file/877047/Press_Notice_March_2020.pdf


Basically, the UK consumes a fudge load of diesel annually. Granted, at least 50% of this is not used and escapes via vehicle exhausts as heat so there is a saving if electric motors and batteries are much more efficient (they are generally in excess of 80% efficient depending on conditions).

The idea of using hydrogen to do away with even some of this diesel (or petrol which I have not discussed) makes my brain ache just thinking about it. Hydrogen is just a PITA as a molecule and means of storing or transporting energy. Natural gas would be a hell of a lot simpler.
