edit: I misspoke, 27% of greenhouse gas emissions are asserted to be from industrial heating applications, not 27% of energy use.
Like, there is some merit in say heating up the "heat battery" at peak solar power (or just when grid energy is cheapest) then using that to heat directly but... you're still doing it at 100% efficiency while heat pump does that at 200-300% using nothing but ambient temperature to get that efficiency.
I guess you could use it as a hybrid solution with heat pump for very cold climates that would normally disqualify heat pumps (heat the brick during the day, use heat pump to get the heat back) but even that is kinda meh.
Thermal storage is one way to execute. Buy solar power when it's cheap at noon and use it for heating at midnight when power is expensive.
Actually it is the complete opposite, wind and solar create a huge PROBLEM with its unreliable fluctuating output.
