@JessePeltan Yes but snow makes this difference so much greater.
A horizontal solar panel covered in snow produces almost zero until the snow is cleared. A vertical panel sheds snow with gravity and collects extra reflected light from the snow below
@JessePeltan Time of use (TOU) pricing would require smart meters for both gas and electricity for all customers right?
Otherwise the utilities wouldn't know which customer purchased what quantity at any time of day.
@JessePeltan 16 hour batteries are already available. Just wire more battery cells in parallel. It's not a change of chemistry. It's just wiring more in cells in parallel for extending runtimes.
@JessePeltan@WernerderChamp Batteries can also be mobile and intermittent to deal with daily or seasonal pricing variations. Electric vehicles are just batteries on wheels.
Point the excess solar in the customer direction instead of the grid, much better economics than any curtailment.
@brian_henderson@DanielleFong@clawrence Agreed. Hydrogen can never beat DC batteries in efficiency cycles. Instead of scarce and expensive Hydrogen, just add more DC batteries to extend runtime.
Thermal batteries are a great way of capturing more energy when DC batteries are full.
@kyrib @ChurchillBarton They are interesting for sure. Thermoelecric plates can be used for both heating and cooling applications.

@NREL No because this idea makes no sense.
Solar DC + Battery DC + Electolysis DC is all you need to produce Hydrogen from H2O onshore or offshore.
Using wind power and AC electricity shows that your researchers don't actually understand that electrolysis is powered by DC.
@EnergyWrapAU@CJPomfret So I noticed in your profile that you are an electrical engineer.
Do you understand the electricity difference between AC and DC electricity?
The utility grid is AC and uses transformers.
Solar and storage is DC and uses transistors.
Which is cheaper and faster to install?
