Seeing Solar In A Different Light

Is Solar Power Dead in the Water? That’s the reductionist headline for a more nuanced op-ed published recently in the WaPo by Robert Glennon. Glennon is a professor of law and public policy at the University of Arizona and the author of an excellent new book,  Unquenchable: America’s Water Crisis and What to Do About […] Read more

Dow Chemical captures solar power with fluid technology

Dow Chemical says it has developed heat transfer fluids which collect, transport and store solar generated heat, technology that shows great promise worldwide.Concentrating Solar Power systems (CSP) with Dow’s heat transfer fluids use mirrors to reflect and concentrate sunlight onto receivers that collect solar energy and convert it to heat. The fluids collect the heat […] Read more

Intersolar Presents Pioneering Technology Awards

The Intersolar trade show has awarded six prizes to six companies intwo categories – photovoltaics and solar thermal technology. Inthe photovoltaics category, Aerowest GmbH, based in Dortmund, Germany,received an award for its AeroSolar software, which produceshigh-resolution aerial pictures. National Semiconductor Corp. receivedan award for its SolarMagic power optimizer, which minimizes the energylosses of photovoltaic installations […] Read more

Concentrated Solar Could Generate 25% of World’s Power by 2050

Concentrating Solar Power (CSP) plants could generate up to 25% of the world’s power by 2050, according to a new report.The report from the from the European Solar Thermal Association (ESTELA), Greenpeace and the International Energy Agency (IEA) says that the projection is based on its “advanced industry development scenario.” Even with a set of […] Read more

The secret to low-water-use, high-efficiency concentrating solar power

Manyreaders have expressed interest in learning more about the waterconsumption of concentrating solar power and how measures to reduce itmight impact system efficiency and cost.  After my recent CSP post, “World’s largest solar power plants with thermal storage to be built in Arizona,” Michael Hogan wrote in the comments (here)about a low-water-consuming cooling system he […] Read more

World’s largest solar power plants with thermal storage to be built in Arizona

What’s the easiest way to deal with the intermittency of manyrenewable sources of energy?  Cheap storage.  And what form of storageis much cheaper and has a much higher round-trip efficiency thanelectric storage? Thermal storage. That’s a key reason concentrated solar-thermal power (CSP) is a core climate solution. It has the most potential of any zero-carbon electricity […] Read more
