Anglo America news
"Anglo American plc, one of AP Ventures’ limited partners, unveiled a prototype of the world’s largest hydrogen-powered mine haul truck designed to operate in everyday mining conditions at its Mogalakwena precious metals mine in South Africa. The 2MW hydrogen-battery hybrid truck, generating more power than its diesel predecessor; is part of Anglo American’s nuGen™ Zero Emission Haulage Solution. nuGen™ is an end-to-end integrated green hydrogen production, fuelling and haulage system for mine sites developed by the Company. The truck marks a significant step towards decarbonising and achieving sustainable mining operations both in South Africa and globally. Anglo American plans to replace the Company’s 40 diesel-powered fleet with green hydrogen systems, reducing emissions and ensuring that eight of the Company’s 27 mines reach carbon neutrality by 2030.

BHP news
BHP, Caterpillar and Finning announced today an agreement to replace BHP’s entire haul truck fleet at the Escondida mine, the world's largest copper producer, located in the Antofagasta Region, northern Chile.Caterpillar 798 AC Weight: 246.56t – Standard tyres: 59/80 R63 – Dump capacity: 187.2m³ – Net load: 372t – Transport length: 15.72m – Transport width: 9.24m
This agreement is part of the strategic equipment renewal process developed by Escondida. The new Caterpillar 798 AC electric drive trucks will feature technology that delivers significant improvements in material-moving capacity, efficiency, reliability, and safety and generate a positive impact in key initiatives for the future, such as decarbonization, diversity and inclusion, autonomous technologies, and the development of local capabilities.
Interesting CAT BHP seem BEV and Anglo is FCEV. Cannot see the details of the battery weight on the Cat BHP trucks. I suspect they are very very heavy!

SubscriberOn the previous page ther eis a cutaway which purports to be how a Hydrogen vehicle works.
However it does not appear to be real world,
Here is a cutaway of a Toyota Mirai 2021.

You will see that the Hydrogen tanks take up a lot more space than implied by the generic cutaway.

Not excited by the Mirai myself Phillip. The technology is has the possibility. I think Probability for large heavy types. My money is where my mouth in a few business in the hydrogen sector so admit bias.Originally Posted by PhilipA
I fully admit to getting on the ground to look under the only Mirai I have seen when charging my car at RACV Torquay nice fast charging spot for my Chemotherpy runs.
I could not see the tanks. They are apparently bullet proof. I always think Bullet Proof is very dependent on the calibrate myselfInteresting I did not note any bumps or lumps on the floor of the car either.
My Diving cylinder is not nearly as high tech and I would be scared to test the bullet theory on compressed air

Landy with 46kva genest owned by Geoff Holloway, now theres an idea, might come in handy for numpties in the mountains who run out of battery.

Super ModeratorHaving seen the remains of the cylinder, the room and photos of the remains of the operator when a diving cylinder went off, you'd be right to be scared.My Diving cylinder is not nearly as high tech and I would be scared to test the bullet theory on compressed air

1000s of refills almost always in a concrete trough Brad. The one that went bang for me was sadly on a ship not in that type of safe set up. I did put a dent or two in the steel of my Dive Store and get a ringing in my ears for a week or two

One of the guys at my local dive shop had a mate of his unluckily lose a leg from a cylinder exploding whilst in the trough filled with water. He told me there is a batch of cylinders from a certain year range that are very prone to going bang as they get older, and they take them out of circulation as soon as they see them come through the store.
Life is just a series of obstacles preventing you from taking a nap.

SubscriberI have now seen quite a few videos of USA vloggers who have towed with EVs and found range reduced by more than 50%
here is an interesting video of Hoovie with his brand new Ford Lightning attempting to tow .
(1) Towing with my Ford Lightning EV Pickup was a TOTAL DISASTER! - YouTube

SupporterWell fossil fuel economy does the same though not that much, my td5 does around 12/100 around town and did 16/100 towing the furniture trailer to melbourne and back.
Maybe caravans will come with their own battery in future to augment the vehicle ?

SubscriberI’ve posted the math somewhere else about this - if he’d been able to use a calculator and Google he’d have worked out those distances were correct before starting out.
Edit - was in the 70,000 orders for the lightning thread here in Alternate energies - I’d post a link but it seems my phone won’t let me for some reason.
If you need to contact me please email homestarrunnerau@gmail.com - thanks - Gav.
