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 Barriers and Obstacles

Location must be in the desert Southwest Unlike solar PV, CSP can’t cope with humidity or cloud cover, so it is limited to the southwest were the solar irradiation is high and there is no dust, haze, or smog.  Solar … 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

Concentrated Solar Power: Water Constraints

“Concentrating solar power plants that use wet cooling could significantly increase water demand, consuming up to twice as much water per unit of electricity produced as traditional fossil fuel power plants. Concerns with concentrating solar power plants are particularly acute … Continue reading
