The trouble is to store that energy cheaply and use it whenever needed.

I call BS!!! Peak electricity usage is at the hottest part of the day. Peak solar generation is at...you guessed it...the hottest part of the day.

When solar is meeting all of the peak demand from air conditioners running at the hottest part of the day, we can then worry about storing some of that power for later.

The only real breakthrough here is a more efficient electrolysis of water. They are bundling it as some kind of solar break though, thats just putting lipstick on a pig.

Actually not quite. Sunlight peaks when the sun is highest in the sky. That would be noon if not for daylight savings time and "time zones". So call it one o'clock, plus or minus a half hour. Peak temperatures are reached about 4 or 5, while peak air conditioning load is a bit later yet.

Ever hear of thermal inertia? The same effect occurs seasonally. The longest day is about 20 June, but the hottest days aren't until late July or early august.

I could write the partial differential equations that explain it, after consulting a text book (it's been a LONG time), but I don't think that would help you much.

Actually, the peak a/c load lags the solar peak by a few hours.

Also, the electricity to run Nocera's new improved electrolysis does not have to come from solar cells. It could be used to store wind energy, as well as solar.

And the energy available from burning the hydrogen does not necessarily have to feed the electrical grid. It could also be used to power vehicles directly.
