You already forgot our previous discussion?

It produces hydrogen without producing any CO2. That is the desirable point. Do you think there's no waste in the production of the gasoline that goes in your car?There has been a development in the past few months of a solar PV panel that will directly electrolyze water, turning it into hydrogen and oxygen.; all with sunshine.
Right. With efficiency around 30%. And then you have to store the hydrogen.
Then you have to get it to the fuel cell. Efficiency maybe 60%.
So you've turned 100 kilowatts of solar output into maybe 18 kilowatts of hydrogen output.
How many should we order?
I've had a change of heart.
Now you don't think natural gas replacing coal is why the US has reduced CO2 emissions?

It produces hydrogen without producing any CO2.
Right.
About 18% of the electricity generated by the panel ends up
as the output of the hydrogen fuel cell.

The average solar panel cost has declined dramatically over the last decade, and solar systems now offer more value to homeowners than they ever have before

If we believe the ^ above green numbers, that would make hydrogen 30-44 cents/kwh.
Is price no object in AOC/Crick economics? Is that desirable?
Do you think there's no waste in the production of the gasoline that goes in your car?
Do you think it approaches the 82% loss for solar hydrogen?
So what. The fuel is free and endless.It produces hydrogen without producing any CO2.

Buying $1,000,000 worth of equipment to get that free fuel is just like buying $5,000,000 worth.
Let me know when your grandchildren break even on your investment.
And buying $1,000,000 worth of fossil fueled equipment isn't "like" buying more, it IS buying more because you will be paying for fuel till it gives up the ghost.Buying $1,000,000 worth of equipment to get that free fuel is just like buying $5,000,000 worth.

Reliable power, still better than unreliable power.
Still weak on economics I see.
Florida, under FP&L, is chock-a-block with solarPV fields but I have never once had my power so much as flicker due to them only working in daylight. Is that something YOU suffer from? Can you identify where all these people are going without power because their utilities are relying on solarPV working on moon and star light?Reliable power, still better than unreliable power.

If you keep enough extra power plants on standby, you can do a lot of expensive, stupid green stuff.
Of course, that requires natural gas.
FP&L has dramatically cut their emissions with all those solarPV fields and the modest increase my rates have undergone is due almost entirely to increases in the cost of fossil fuels.If you keep enough extra power plants on standby, you can do a lot of expensive, stupid green stuff.

Florida Power Bills To Spike (again!): Reliance on Fossil Gas Largely to Blame - SACE | Southern Alliance for Clean Energy
If you’re a Florida electricity customer, brace yourself, your power bill is set to spike again. The culprit is the Florida utilities’ reliance on fossil gas (also referred to as natural gas)…

"...[Texas] produces more wind and solar power today than the next three states (California, Iowa, and Oklahoma) combined, and that lead is growing. Last year Texas added more new renewable power generation than the next five states together. The American Clean Power Association, a trade group representing wind-, solar-, battery-, and hydrogen-energy developers, recently testified that renewables projects have invested $93 billion in Texas during the past couple of decades and generated $684 million combined in lease payments to landowners and taxes to counties and school districts.
One recent estimate found that renewables Lowered the cost of electricity to Texans by $11 billion last year, or $423 for every customer served by the state’s predominant power grid. Over the past five years, Texas has added 2,800 jobs to support wind and solar power generation at the same time that the state has lost 44,000 oil and gas extraction jobs, in part because automation has allowed producers to drill more wells while employing fewer roughnecks.
The abundance of low-cost clean energy—a growing priority for global corporations—has also driven companies to put new facilities in Texas."...:"
