Hydrogen can also be made using electrolysis of water. ... Very roughly, a new electrolysis plant today delivers energy efficiency of around 80%. That is, the energy value of the hydrogen produced is about 80% of the electricity used to split the water molecule.
I won't bicker with the bot, but we can compute the equivalent of electric vs hydrogen cell cars.
The cost of conversion, in place, of solar-> hydrogen is about .2 * .8 = .16. But the result is stored hydrogen energy, take away half for pumping and we get 8% solar conversion for local stored hydrogen. Given one capital investment of (reusable) water and sun, about 8% of that solar area is labor free conversion of hydrogen. Solar in the day, running hydrogen burners at night, keep the lights on 24 hours. You have to cover both phases, so half your energy being used, half stored for the night.
OK, I will take a banana for that great idea, one single area with a large pool of reusable water.
Now repeat the trick with electric driven carbon extraction and conversion to liquid fuel. Or electric driven, closed circuit algae farms, or electric driven fermenters. Ship the corn to a local processing plant with huge solar area, in place solar assisted biofuel, low impact.
We are getting bang for the buck with solar panels, let us talk about large in place energy conversions facilities, all driven by electricity. Electricity is great energy, easy to control with efficiency. With electricity we can expand the range of biomaterial we can ferment, we can add energy in. All of this is focused, small but complete conversion plants, pilot program size. But there is no subsidy beyond capital equipment and some maintenance. This idea scales. the best part, we are not build huge piles of lithium everywhere but get all the advantages of solar electric.
Energy available at 340 watts per square meter. . About 1 Mw times .2 = 200 kw per acre. A thousand acres is 200 MW, if I am not mistaken. That is the energy available to make a storage tank of hydrogen. Then comes the 80% efficiency and pressurizing costs.
Closed cycle. Burn the hydrogen and generate steam, use the steam then cool it to water and electrolize it. Like a refrigerator or steam engine.
I consulted the google bot and got this:
OK, make that 400 kw per acre. Conversion, delivery, and pressurizing efficiency about 40%. or 20 kw per hour to 10 homes. One home in a rural environment could set aside a quarter acre and have a smaller closed system.
Relative comparison is my county, 3.8 million acres. Now that is about 3.8 million football fields, each football field supporting 10 houses. In terms of area, what about the USA at 300 million people? You need ten counties the size of this one:
The county covers a big chunk of central California. But from Sacramento, down to Bakersfield we can get four of five of these counties.

I consulted the google bot and got this:
Scientists have developed a solar cell that is capable of converting direct sunlight into electricity with 44.5 percentefficiency — making it, potentially, the most efficient solar cell in the world. Current solar technology only converts electricity with a maximum efficiency of about 25 percent.
