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

CSP with thermal energy storage is seasonal, so it can not balance variable power or contribute much power for half the year

Concentrated Solar Power not only needs lots of sunshine, but no humidity, clouds, dust, smog or or anything else that can scatter the sun’s rays.  Above 35 degrees latitude north or south, the sun’s rays have to pass through too … Continue reading
