GM Assembly Plants Going Solar

20/05/2011 Comments off

General Motors has taken a number of significant steps to make their vehicles greener, and they are doing similar things with their manufacturing plants, as well. This week, the company has made two announcements about using rooftop solar arrays to power its manufacturing facilities.

The DetroitHamtramck plant, which produces the Chevy Volt, will be having a 516 kilowatt solar array installed on six acres of land on the south side of the plant as part of a cooperative venture with the local electrical utility company, DTE. Using power from the solar array is expected to save GM $15,000 per year.

Solar panel installations may surge in the next two years as the cost of generating electricity from the sun rivals coal-fueled plants, industry executives and analysts said.

Large photovoltaic projects will cost $1.45 a watt to build by 2020, half the current price, Bloomberg New Energy Finance estimated today. The London-based research company says solar is viable against fossil fuels on the electric grid in the most sunny regions such as the Middle East.

“We are already in this phase change and are very close to grid parity,” Shawn Qu, chief executive officer of Canadian Solar Inc. (CSIQ), said in an interview. “In many markets, solar is already competitive with peak electricity prices, such as in California and Japan.”

Department of Energy Awards 3M $4.4 Million to Reduce Cost of Photovoltaic Energy Systems

The U.S. Department of Energy (DOE) has awarded 3M $4.4 million as part of DOE’s SunShot Initiative. SunShot aims to reduce the total costs of photovoltaic solar energy systems by about 75 percent, so that they are cost-competitive with other forms of energy without subsidies. SunShot calls for achieving this goal by the end of the decade. The sum of the 3M award is estimated at $4.4 million over three years.

The goal of 3M’s project is to accelerate efforts toward further development and commercialization of 3M™ Ultra Barrier Solar Film. The funding will support a reliability test program to validate the lifetime performance of the film as well as development of second-generation 3M Ultra Barrier Solar Film with enhanced performance and reduced costs.

As part of the initiative, 3M will collaborate with DOE’s National Renewable Energy Laboratory (NREL) to test the performance and durability of Ultra Barrier Solar Films. NREL recently confirmed moisture vapor transmission rates in the range of 2*10-5 – 8*10-5 g/m2/day for 3M’s current Ultra Barrier Film 9L product using its electrically based calcium moisture vapor transmission rate (MVTR) test. “Technology for economical production of transparent barrier films has been a missing link in the flexible CIGS photovoltaic supply chain for a long time, and we are looking forward to working with 3M in the development of this technology,” says NREL senior scientist Mike Kempe.

“We are delighted that DOE has recognized the relevance of 3M’s Ultra Barrier Solar Film toward achieving its goals for driving down the cost of solar,” says Derek DeScioli, business development manager for the 3M Renewable Energy Division. “High-efficiency flexible solar modules manufactured with 3M’s Film not only have the potential to significantly reduce the total system costs for rooftop solar installations, but also have an array of niche applications where our customers can take advantage of the unique module form factor.”

Designed to address the needs of flexible thin film solar manufacturers, 3M Ultra Barrier Solar Film acts as a replacement for glass with high light transmission, moisture barrier performance and strong  weatherability.

A new study published in the journal Energy Policy says that we could achieve 100 percent renewable energy by 2030, and not just U.S., but the world.  The study says that we have access to all the necessary technology, but strong political would have to exist for it to happen.

So, how can we get to 100 percent renewables by 2030?  Well, to be exact, the study says we’ll need:
