Can concentrated solar power be used to generate industrial process heat?

Preface. The bright future of solar thermal powered factories, makes some important points about using concentrated solar power to generate heat: “…A large share of energy consumed worldwide is by heat. Cooking, space heating and water heating dominate domestic energy … Continue reading

Why Concentrated Solar Power is not a good choice for a 100% Renewable Energy System

Preface.  The authors conclude that: In light of the obtained results — a low capacity factor and Energy Returned on Invested, an intensive use of materials—some scarce, and the significant seasonal intermittence) — the potential contribution of current CSP technologies … Continue reading

Why is nearly all solar power built where subsidies are the highest?

If solar net energy return is as high as some solar advocates claim, why does solar need any subsidies? And not just U.S. subsidies, it’s subsidies on top of subsidies when you add in that we’re buying Chinese government subsidized … Continue reading

The potential role of concentrating solar power

Preface. 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 … 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
