More efficient energy storage has been a difficult issue for scientists to crack. It is a major issue preventing more widespread use of renewable energy, and solar energy in particular.

Is this project, one funded by a true oil giant, the one that will make it happen?

The $16 million upgrade project is funded by ARRA (American Recovery and Reinvestment Act).  Parkson’s Thermo-System Active Solar Sludge Drying Chambers will enable the sludge conversion process to operate under more than 90% solar power rather than using gas or oil.  For disposing sludge in landfills, that translates into a significant savings in preparation and transportation costs.  Even better, it makes sludge products more cost-competitive with conventional soil amendments and fossil fuels, effectively taking the “waste” out of wastewater.

Renewable Funding’s PACE (Property Assessed Clean Energy) solar funding, begun by Cisco DeVries with Berkeley First was a breakthrough in making solar affordable. Now VC high-flyers Draper Fisher Jurvetson, New Cycle Capital, and RWE Ventures have just invested $12.2 million in a first round of financing to make this sober and sensible solar funding available to more homeowners.

Renewable Funding is a business in the Common Good. And it could be big too. There’s potentially a gigaton of greenhouse gas reductions to be made, at no cost to local, state, or federal governments from a $280 billion potential market in PACE solar funding in the US, acording to a UC Berkeley study published in Environment Magazine.

Theirs would be the first heliostat type of solar array to produce grid power in California. Abengoa has several in Spain, and plans one in Arizona. United Technologies has licensed the original technology to the new company SolarReserve and its wholly owned subsidiary Rice Solar Energy, LLC, (RSE).

Pittsburgh has been laying the groundwork for a high tech green jobs renaissance ever since its mighty steel mills shut their doors 30 years ago.  Now the payoff is coming.  FLABEG, the global specialty glass manufacturer, has just opened a solar mirror factory by Pittsburgh International Airport that will bring an estimated 200 jobs to the region, and perhaps as many as 300.

The new $30 million facility will initially focus on its core production line of parabolic curved solar mirrors.  Months before the plant opened it already received 700,000 orders, and FLABEG expects to reach a capacity of 1 million mirrors annually.

Researchers at the Georgia Institute of Technology have made a three-dimensional photovoltaic solar cell around an optical fibre, a revolutionary new approach that could pave the way for a new generation of hyper-flexible solar systems.

According to team-leader Professor Zhong Lin Wang, “Using this technology, we can make photovoltaic generators that are foldable, concealed and mobile. Optical fibre could conduct sunlight into a building’s walls where the nanostructures would convert it to electricity. This is truly a three dimensional solar cell.”

Why Concentrated Solar Power

Two of the widely used alternatives for collecting the suns energy are the concentrated solar power (CSP) plant where sunlight is focussed on a receiver in which a circulating working fluid is heated and used as the heating media for a conventional power station and the photo voltaic (PV) plant where sunlight is converted directly into electrical energy.

A partnership between two companies will develop a home energy monitoring device for residential solar power installations.

Two startups – Tendril Networks, known for its home energy monitoring technology and Fat Spaniel technologies, a solar panel monitoring company – make up the partnership. The purpose of the partnership is to develop a monitoring device for homes that can gauge the sun’s intensity for any particular time and automatically adjust, or even shut down, home appliances as needed.

Dell has been a trend-setter when it comes to the incorporation of greener technologies to reduce their corporate carbon footprint and they’re doing it again! Although this time they are following the lead of Google, by installing solar trees in the parking lot of their head office in Round Rock, Texas.

The new technology could be attractive in land-rich areas, and it may also have some application for introducing sustainable energy to more densely developed areas, since its use of high efficiency solar cells enables it to pack more generating capacity into less space.  It also may prompt some new exploration of the opportunity to double up solar energy generation with other operations, such as fish farming.

A contract has just been signed to deliver 600 gigawatthours a year of solar power between the US division of Spain’s giant Abengoa, and PG&E in California. Abengoa Solar hopes to succeed where BrightSource recently failed to overcome local NIMBY issues and Senator Feinstein, in its plan to site a 250 MW solar thermal plant in the made-for-solar Mojave Desert.

If the black areas above were covered with PV panels, it would provide all the world’s energy needs.

The Clinton Climate Initiative (CCI) is convinced that the contribution of solar energy to the world’s energy needs is about to boom. It is already developing projects in India, Australia and in the South Western States of the US. Now it is co-operating with the Department of Minerals and Energy (DME) to develop a Solar Park in the Northern Cape that would speed up South Africa’s uptake of renewable energy.

Instead of silicon, compound solar cells use two or more photo-absorption layers composed of different elements.  The trick is to find materials that generate the most current with the least waste.  Sharp’s innovation is a proprietary technology that enables it to produce a high-efficiency crystalline compound, InGaAs (indium-gallium-arsenide), which boosted the efficiency of Sharp’s previous cells from 31.5% to 35.8%.

Solar disinfection is a proven method of killing germs in drinking water by exposing it to direct sunlight in a clear plastic or glass bottle.  Dr. Jaehong Kim of the Georgia Institute of Technology has just been awarded a $100,000 innovation grant by the Water Environment Research Foundation for his work in developing a new coating that could be applied to bottles to shorten the solar disinfection process and improve its effectiveness.  Though not (yet) practical for large volumes of water, solar disinfection has proven to be a sustainable answer for people in remote locations or impoverished areas that lack the resources to disinfect their drinking water through other means.

Just the other day, I wrote that it was a great time to go solar, especially due to the great rebates and discounts on solar technology. Apparently, I jumped the gun and was a few days early. A new report by Lawrence Berkeley National Lab — “Tracking the Sun II: The Installed Cost of Photovoltaics in the US from 1998-2008” — shows a significant decrease in solar costs over the last ten years and shows that now is a great time to go solar.
