Solar Thermal

Acciona's financing of Nevada Solar One, and a recent series of a financing, a prominent hire, and a big announcement from Concentrating Linear Fresnel Reflector (CLFR) developer Ausra has been keeping long-underappreciated Concentrating Solar Power (CSP) technology in the news recently.  I consider this great news, because the potential for cheap thermal storage of CSP and the gigantic size of the available resource means that CSP is likely to provide the backbone of reliability for any future decarbonized electric grid where the clear skies which it requires to operate properly and sufficient transmission are available. But CSP is...

Dana Blankenhorn This article is no longer available. Disclosure: None Dana Blankenhorn first covered the energy industries in 1978 with the Houston Business Journal. He returned last month after a short 29 year hiatus because it's the best business story of our time. In between he covered PCs, the Internet, e-commerce, open source, the Internet of Things and Moore's Law. It's the application of the last to harvesting the energy all around us he's most excited about. He lives in Atlanta.

Bribing and Pressuring Fissile Regimes On July 25th, France offered to build a nuclear reactor for Libya to power a water desalinization plant.  Russia is delaying the delivery of  nuclear fuel for Iran's nearly completed Bushehr to help pressure them to comply with UN Security council demands for less secrecy.  South Korea, Japan, China, Russia, and the United States promised to provide 950 thousand tons of oil or equivalent aid to North Korea in return for permanently disabling all its nuclear facilities. I'm not going to argue about whether using energy aid is the best way to influence this...

Joe Romm, at the influential Climate Progress blog, has hit on a formula for countering the coal industry's claims that we need baseload power sources.  Since Concentrating Solar Power (CSP) in conjunction with thermal storage can be used to generate 24/7 or baseload power Joe has renamed it "Solar Baseload."   This is win-the-battle-lose-the-war thinking.  While it does neatly counter the argument we need coal or nuclear, since there are renewable power sources which can produce baseload, such as CSP, Geothermal, and Biomass.  I fell into this coal-industry trap myself in a 2007 article about Geothermal, as did AltEnergyStocks...

Dana Blankenhorn If there is one thing I've learned as a tech reporter it is that failure is common, but what we learn from failure can often lead to greater success. Back in 1984 I was asked to help write the manual for a start-up called The Promise. The Promise would offer home banking, home shopping, and information services, delivered to your PC. The Promise failed almost before the lights went out on the press conference. It was at least a dozen years too early. There was no Internet, and I worked on a double-floppy IBM PC. Fortunately...

Like most conglomerates, United Technologies Corporation (UTC), (NYSE:UTX) won't be found in any of the Clean Energy indices, but its growing portfolio of clean energy businesses makes it fit well into a diversified portfolio with a clean energy tilt.  A conservative capital structure and solid earnings and cash flow, and a decades long history of constantly increasing dividends make this a company that I'm comfortable holding for the long term.   In terms of sustainability, the company has been recognized by Dow Jones as in the top 10% of the world's most sustainable companies.  Long before it became fashionable for...

Tom Konrad CFA The falling price of photovoltaic (PV) solar is undermining the case for Concentrated Solar Thermal Power (CSP).  According to a recent report from Pike Research, of the 6886 MW of CSP projects awarded in the United States since 2004, 36% have been replaced with PV.  That's more than the number which are actually under construction (1,532 MW, or 21% of announced projects), and all of those required the backing of the US DOE loan guarantee program. With this recent track record, and no ...

Tom Konrad, Ph.D. When Solaren announced they are seeking PUC approval for a power purchase agreement (PPA) with PG&E (NYSE:PCG) for solar power from outer space, I wasn't too surprised.   California utilities signing deals for large solar projects which quite likely may never be built is something of an industry trend.  At a Concentrating Solar Power (CSP) conference last fall, John White, the Executive Director of Cleanpower.org, said that competitive solicitations for power supplies in California are becoming a sideshow, and that the "Process lacks credibility among the most serious and qualified developers."  Rainier Aringhoff, the president of one...

When the financial turmoil began, I sold my riskiest stocks.  Even a successful bailout bill is unlikely to return us to the heady days of 2006 and 2007.  Yet there is a bright side for clean energy investors.  Despite the recent evidence to the contrary, a financial crisis is likely to convince legislators of the importance of getting the economy going again, and of doing so with the least amount of public money possible. Concentrating Solar Power It was with this thought in mind that I attended CSP Today's Second Annual CSP Summit US in San Francisco. ...

Cerium - an oil saviour? Eamon Keene Making fuel from solar energy is the holy grail of the renewable industry. In 2008, David Nocera, an energy professor from MIT, gushed about a "major discovery" which would unleash a solar revolution. The MIT press reported on a "simple, inexpensive, highly efficient process for storing solar energy". Ostensibly this was a way to split water to store solar energy in the form of hydrogen and each house would have its own solar panel, which would mean that "electricity-by-wire from a central source could be a...

Parabolic Troughs have dominated Concentrating Solar Power (CSP) until recently, but several companies are vying to replace them. Will the upstarts succeed, or will incumbency and improvements to trough technology ward off the competition? Dr. Arnold Leitner, CEO of Skyfuel, Inc., thinks the battle for dominance of CSP will be "winner-take-all." The technology which can deliver power when it is needed at a reasonable price should triumph. Photovoltaic (PV) technologies are rapidly producing price reductions, and can be used almost anywhere, but only produce power when the sun is shining. In contrast, CSP is still cheaper than PV enables...

by Debra Fiakas CFA In the last post on Brightsource Energy and its Ivanpah solar thermal power plant in California, I offered no investment opportunity.  Brightsource’s colossal configuration of mirrors and boilers in the Mojave desert is not the first solar thermal power plant using the tower configuration.  The solar subsidiary of Spain’s power generator and transmission leader Abengoa S.A.(ABGB:  Nasdaq) was first to market with a commercial solar thermal tower power plant near Seville. Since construction first started in 2004, Abengoa Solar has brought a series of solar thermal...
