Whoop-dee-do! Katy bar the door!

how do you keep it from rusting?

[Honorary Serb]

Someday, we shall have better “green” energy technologies—when we really need them!

There’s really no need to rush, unless you’re a tyrant trying to crush humanity!! Modern civilization cannot be run on solar, wind, and batteries!!!!

[Bonemaker]

"Hydrogen fuel cells convert hydrogen to electricity..."

And then converts to fire.

[reg45]

Now crooks won’t try to steal your fuel cell just to get the platinum.

[riverrunner]

Yep just around the corner. again

[rktman]

Kinda my thought too. And, I have some experience with hydrogen.

[Myrddin]

Hydrogen still needs to be generated from another energy source. It can be separated from natural gas or by electrolysis of water. Either way, it's just a store of transformed energy into a difficult to store form. The clean "burn" of hydrogen is desirable in the isolation of a space vehicle. Solar cells make sense in the same context. The extra expense can be justified in that special use case. It doesn't make a lick of sense for the terrestrial commuter. Diesel/gasoline/liquid propane make the best fuels for vehicles. Great energy density that is rapidly replenished in the process of traveling.

But da Erf! We gots ta save da Erf!...............

Modern civilization, no. Medieval Civilization, yes.............

[PubliusMM]

Good News, surely.

[ImJustAnotherOkie]

Ahh...Zirconium

Since catalytic converters also use platinum and since they won’t be necessary with a hydrogen fuel cell, then I would think that there would be a cost offset.

Am I missing something here?

[Tell It Right]

I was interested in buying a hydrogen electrolyzer to produce hydrogen for long term storage for my home solar system. But at best they lose 50% of power round trip from power to create gas to later generating electricity from a hydrogen fuel cell.

Meanwhile battery costs keep going down and I get about 95% round trip efficiency from that power storage.

[Red Badger]

Platinum is used in a myriad of things, precision temperature sensors, jewellry, metallurgy, medicine, etc.................

Look up Formenergy they are commercializing a Iron air battery that is based on the Edison cell but w/o the nickel side of the cell. Edison cells have cycle lifetimes in the 40,000+ range there are Edison cells from over 100 years ago still in active use. They are targeting $20 kWh in LCOS that’s nothing short of a paradigm shift. Even at 50% efficiency at those costs you could put up panels for 18 cents per watt lose 50% and still be cheaper than the grid wholesale even three times cheaper than retail.Iron cells are not 50% they are 90+% round trip efficient. Making the numbers even better. The batteries are the size of washing machines and industrial strength no fragile lithium cells. Georgia LP just signed up to do the first grid scale test with 1500 megawatts hours of storage that’s equal to one of the South Texas nuclear plants reactor output for an hour. Or a large sized Hydro electric plant. They plan on using it to store solar during the day and let it back to the grid at night. With Edison cell cycle lifetimes as all Iron anode exhibit they should easily get too $20 kWh the expensive part is the nickel cathode. Iron is cheap and easy to recycle as well. It’s one of the most abundant elements on earth second only to aluminum and silicon in the crust. For off grid set up Formenergy which is a spin-off of MIT is going to set the bar for storage. Iron nickel cells are routinely used for off grid applications today they beat lead acid in energy metric including LCOS which is levelized cost of storage the all in over the entire life span cost to storage energy round trip.

Sounds promising and fantastic. Let entrepreneurial and technical research lead the way and not government edicts nor regulations. Develop away but leftards need to stop vilifying fossil fuels which are very necessary for current production of systems that fuel the economy. Dont destroy what currently is working in the name of ‘progress’.
