Here you go Mick Marsh ,
Take your Trailer to Sydney & back with A/C on full blast , Recharge almost as fast as filling with petrol.
Another company that won't remain Australian for long.

Oh, sadly not.
Sadly, the news article reports on the 475kW fast EV infrastructure being installed in Europe, not Australia. Not applicable here.Quote:
In Australia – where the electric vehicle market is moving at a glacial pace – Tritium has been slightly less busy.
Although just last month, the company was tapped to supply its Veefil 50kW fast chargers for a $10 million EV fast-charging network being rolled out across New South Wales and the ACT by the NRMA.
The Australian installed solution is one tenth the size and within one state, NSW. I'm tipping it will probably be centred around the urban areas.
I concur, and as usual Australia is 20 years behind the rest of the world ( Make that 30 in SA and 50 in Tas)
I can hardly wait for what is promised to happen. Electric motors are so much better than an ICE motor in performance, efficiency and construction.Quote:

I don't think it will happen in my lifetime. There is still plenty of oil being pumped and refined. We use so much petrochemical in our daily lives, I don't think it will go away anytime soon.
Fuel cells have already come and gone as far as domestic units go. A few years ago you could have bought one for your house that would supply all your electricity and hot water from your natual gas supply - a bargain at $35,000! Add to that they were less efficient than a gas fired power station and the maintenance was a nightmare and you have a comany (Bluegen) that went into administration in 2015 and was removed from the asx recently although you can still buy them overseas - BlueGEN Fuel Cell - SOLIDpower - with no OEM support here any more, when the stacks need replacement you'd have done your doe.
For that price now you could do a decent off grid system with batteries and solar. 😉
As for vehciles I still think hydrogen fuel cells have merrit but there seems to be a lack of motivation within the industry to go down this path for some reason, even though the tech is proven, hydrogen can be stored safely and it's theoretically 'clean' to produce although I'd like to see the solar farm that would be able to do that on a commersial scale.
The best hydrogen producing station I saw was powered by a couple of wind turbines and the plant (electrolyser, compressor, etc.) was in a small shipping container.Quote:

Headlines in the media:
Quote:
A new solar and wind hydrogen plant, which has been dubbed the largest in the world, has been proposed for Crystal Brook in South Australia's Mid North.
Here's an opinion piece:Quote:
The Crystal Brook facility will produce up to 400 megawatts of solar and wind power each day, which will power the site's hydrogen 'electrolyser' to potentially produce 20,000 kilograms of hydrogen daily.
Energy Voice | OPINION: Hydrogen is really happening - News for the Oil and Gas Sector
What are the energy losses going solar->hydrogen->electricity vs solar->batteries->electricity? Was thinking that hydrogen may be an easier energy medium to store large capacities and transfer between storage vessels?
According to Wikipedia production of hydrogen by electrolysis should be around 60% efficient. If the vehicle runs a fuel cell, (currently very, very expensive) efficiency of this would be around 80%, giving an overall efficiency of about 50%. If it runs an ICE (more likely), with an efficiency of perhaps 35%, overall efficiency is around 20%. Compare to an EV with a charge/discharge efficiency of perhaps 80%.
Despite claims to the contrary, hydrogen remains difficult and expensive to store or transport or distribute. It is not generally as dangerous as many think, but that is solely because it disperses very rapidly in the atmosphere because of its low molecular weight. It will permeate through almost anything when under pressure, and is explosive over a very wide range of concentrations, as well as being colourless and odourless. This means that it could disperse widely undetected and then ignite explosively over a wide area.
