Blackstarting the grid after a power outage

Blackstarts Large blackouts can be particularly devastating and happen much more frequently than a normal distribution predicts. The impact of a blackout exponentially increases with the duration of the blackout, and the duration of restoration decreases exponentially with the availability … Continue reading

The potential role of concentrating solar power in enabling high renewables

[The word “water” appears nowhere in this document, even though that’s a major limiting factor for CSP with thermal storage. Dry cooling is possible, but it lowers the EROI and raises the already way-too-high capital cost. An electric grid that’s … Continue reading
