On: EPA rules would force coal-fired power plants to capture emissions or shut down

[pfdietz]

Yes, I see that's the case. I imagine that's because of all the existing combined cycle plants. The new rule also doesn't apply to peaker plants.

The folks with the Allam cycle patents must be happy about this.

Peaker plants are not cost competitive with utility scale battery storage, storage which is currently supply constrained.

They're not cost competitive with batteries for diurnal storage, but they are competitive for low duty cycle demand on much longer time scales (like covering Dunkelflauten).
