SunHydrogen #sunhydrogeninc spins their weak Austin, TX test results:↙️
1) As my wicked-smart #GinerInc mentor Tony LaConti always said, "there's no such thing as a defect-free coating"
2) There's a good reason Nocera & his artificial leaf startup #SunCatalytix failed on the same task, and pivoted away from PEC!↘️
3) Don't forget, you can always over-build your solar, add a battery, and keep an electrolyzer running 24x7x365!

@keithdpatch for now, I don’t see many ways to energy independence with heating in mind (heat pumps are electric)
There’s heat storage, but it requires incredibly big projects and there aren’t that many around yet
Or there’s overcommitting on solar by at least 5x, getting batteries for the night and dealing with the (huge) excess in the summer, which might as well be H2 production
@keithdpatch ok so, say we can’t solve seasonal energy storage, at least for a while
That means we’ll have to increase dramatically our renewable production, which, for most people, means more solar (wayyy more solar)
That also means lots of excess energy production in the summer that isn’t stored, at least not in sufficient quantity for the winter
What could feasibly be done with it? Could we produce H2 and send it to the industries that require it, so that they suddenly become green half the time?
@GuillaumeRossolini
Sorry, we can solve seasonal energy storage TODAY with excess summertime green hydrogen production that is stored underground.
Underground hydrogen storage has/is currently operating in salt domes AND aquifers AND depleted gas reservoirs (pores). https://bit.ly/3EMaK2u
And there are other, newer options being developed.⬇️
@keithdpatch we can? If we replaced all the current burners with heat pumps, there would be enough capacity for everyone?
[edit] From the article:
Porous media storage solutions are estimated to have capacities which far exceed projected storage demand
Ok then, I’m baffled that we aren’t going this and that the common belief is still that hydrogen can’t be stored, since the molecule is so tiny
@GuillaumeRossolini
Well, there are a lot of hydrogen haters out there, who think the answer is to electrify everything. So they spread misinformation, stretch the truth, and sometimes lie in order to make hydrogen seem silly/etc. ↙️They never admit you can't electrify long-haul aviation or heavy shipping, etc.
