Potential and risks for U.S. glass industry

“Glass and energy” was a theme high on the agenda at the 20th glasstec in Düsseldorf, Germany, Oct. 21-25. The “glass technology live” show symposium offered insight into the future of glass technology. Organizer Stephan Behling, senior partner, Foster and Partners, London, and his team from the Institute for Building Construction at the Stuttgart University, Germany, compiled an array of current product developments, architectural projects and tomorrow’s technologies, including a lot of solar.

“There’s more hype in solar than business, with the exception of Germany and Spain,” said Russell J. Ebeid, president, Glass Group, Guardian Industries Corp., Auburn Hills, Mich. “But I believe it’ll come; it’s not a fad.” The solar hullabaloo reminds him of Silicone Valley in the 1970s, he said. “You met IT folks who thought they’d all be Dell; but the number of manufacturers slimmed down. Same way with solar, they all think they’ll be billionaires in three years.”

Chris Mammen, president, M3 Glass Technologies, Irving, Texas, shared a similar opinion: “I’m worried that the industry is buying into something too quickly as far as solar is concerned,” he said. “The industry is expending millions in this, but is this going to turn around for all? For some, it might; for others it might be the final nails in their coffin.”
Ebeid believes it’ll be about seven years before solar takes off as a viable source of alternative energy. As research continues, solar prices will come down and electricity prices will keep going up; they’ll meet at some point, he said. “There will be a race for intellectual property and patenting.”

The U.S. is starting to wake up as far as solar power is concerned, Ebeid said, and much of it is in the south. “Florida wants to produce solar energy but they have hurricane codes and they’re looking for laminated solar panels,” he said. “No one does that yet; it is being developed.”

There are a few solar technologies available in the market: solar panels, silicon wafers, CSP, troughs, etc., and no one technology will work everywhere, he said (Click here to read about photovoltaic growth in the U.S). “If you’re in New York, you can’t put a solar field, for instance. In a crowded city, you might have a car port that feeds the adjacent apartments.

“If I take all the technologies, I don’t know which would win,” Ebeid said. “So you put little bit of money in each. Someday, all those will consolidate and become two or three kinds and some big company will buy up the smaller companies and become a giant like GE,” he said. “Guardian’s placing small bets on all.”

Current solar jobs being bid in the U.S. will consume at least eight float plants in the world, Ebeid said.

The global players are well aware of the trend, Ebeid said; Cardinal, Guardian, PPG, Pilkington are all into solar. “Asahi and Saint-Gobain are big players,” he said. “First Solar’s a big name. Applied Materials, that makes coating machines, are looking at [Guardian] to make a specialized coating for their machines.” When you are a global player, you can suck off of each other, he said. “The smaller players will become commodity manufacturers.”

The Europeans, who have the technology, see the opportunity in the U.S., and are coming to the U.S., Ebeid said. Rio of Spain has gone into Mexico, and Flabeg of Germany has gone into the U.S.

However, all solar projects rely on government subsidies because the cost is not comparable to fossil fuel rates, Ebeid said. “When you have to rely on the government, they’re pretty fickle because they rely on people who elect them.”

Bill Yanek, executive vice president, Glass Association of North America, Topeka, Kan., agreed. “Since mid-1980s, the U.S. has lost ground to the Europeans in solar technology/alternative energy,” he said. “It’s the use and the government support that’s helping Europe. So, I don’t know that the technology’s that much better in Europe.” However, the U.S. Department of Energy’s looking for federal research grant money to ramp up the effort and foster support for the industrial work groups in ASTM standards on solar glass, he said. “DOE got a tax credit for renewable energy in the recent bailout. Their technical folks are looking at how to increase the efficiency of photovoltaic cells.”

John Faour, president, Faour Glass, Tampa, Fla., had a similar opinion: “The Europeans spend more money on construction because they get government money. They want that building to last, so they’re interested in energy savings more so than trying to make it cost-effective. So much of what we do in America is return on investment.”

On the glaziers’ front, “the subject of PV technology and other energy conserving glass developments can be developed by us by exposing these developments to our customer base,” Faour said. “While we may not be qualified to provide specific design and application criteria, we can expose the concepts and perhaps provide contacts for them to get more education.” This consultative approach can help glaziers get closer to the customers and together learn how to apply these technologies in the future, he said. For the right customer this should help to develop the relationship and create loyalty. “In this day of shrinking work load and highly competitive bidding any edge that can be created can be invaluable,” he said. “A glazing firm that is on the cutting edge of what’s new will be highly sought after versus the ones that take a reactive approach to our industry.”

  • Solar products attract much interest at glasstec

    Solar product exhibitors at the 20th glasstec fielded plenty of solar-related queries.
    The theme of the show—solar--is pretty much is the trend in the industry today, said Jay Molter, vice president, Marketing & Sales, Glasstech Inc., Perrysburg, Ohio. “We’re getting a lot of inquiries on photovoltaics, thin films and troughs,” he said. “There’s a steep growth in inquires. Couple of years ago we were only getting a few queries, it’s a significant growth.”

    Glasstech showed the CRB-S, EPB-S, DB4-S. The Cylindrical Radius Bender is a tempering/heat strengthening/low-stress glass system for producing large low-iron glass for parabolic solar reflectors. The External Press Bender is a tempering/heat strengthening system for smaller, high volume spherical and parabolic shapes. The Deep Bend 4 is a tempering/annealing system for producing smaller/high volume spherical and parabolic solar collector deep bend parts for CSP and CPV.

    Besana, Italy, introduced a double-edger with multi spindles, SQ10 T, that got much attention, said Brian Martineau, sales agent, Besana Lovati, Winston-Salem, N.C. “The edge of the glass preparation is important to the solar industry, because if there are any fractures in the edges, the glass will burst when installed in a module on the roof,” he said.

    The tempering oven at the Lisec booth piqued interest, said Manfred Lesiak, marketing event manager. The company has the largest single company stand, 2,600 square meters, at the show and is showing a complete factory setup with interlinking machines. “At the heart of solar glass production is the tempering oven,” he said. “Our oven makes 2.1 millimeter glass that can be used for solar glass. It produces no roller waves and the tempering is of superior quality.”

    Carlo Strappa, marketing manager, Intermac, Italy, said the company’s double-edging machine was good for solar glass. “It tracks the coated side and treats it very gently,” he said.

    Schott Solar’s glass with photovoltaics inside was a big draw, said Frank Albrecht, sales manager, architectural glass, Germany.

    Euroglas, Germany, introduced two solar control and thermal insulation products: Silverstar Combi Neutral 41/21 and Silverstar Selekt T, said Cornelia Held, Marketing and Beratung, Silverstar.

    Saint Gobain, France, introduced four concept glasses at the show: Electrochrome Control Glass, GlassXcrystal, Cool-Lite Xtreme and Climatop Max, all solar control products with high transmission rates and low G value, said Janina Rudnizki, assistant, Marketing & Vertrieb. “The Climatop Max is for zero energy buildings,” she said. Other Saint Gobain products that got attention were: the SG Photovoltaic Glass line with extra white cover for solar modules and collectors: SGG Albarino S and SGG Albarino T with 91.5 energy transmission; and SGG Albarino P and SGG Albarino G that increases electricity yield of PV modules, do not accumulate additional dust and efficiency increase outdoors of up to 12.5 percent. The Miralite Solar line also got much attention, Rudnizki said.

    AGC Flat Glass Europe, Brussels, showed its TCO coated glass, said Jeroen Schotsaert, product manager, Thin Film PV Solar Glass.

    Glaston, finland, introduced two solar machines at the show: the Tamglass CHF Pro, for architectural and PV solar glass tempering, and the Tamglass ESU EcoPower, to meet the demands of curved solar glass. ”The ESU automatic bending furnace shapes the glass at the focal point of the reflector with extreme accuracy,” said Topi Saarenhovi, senior vice president, Heat Treatment. ”It has a serial bending with radiation and heat recovery assisted convection for an accurate and energy-efficient process.” The machine was surrounded by curious attendees and potential custometrs at most time of the day.
