HelioVolt hopes for a fast scale-up with high-efficiency CIGS process » Ventu... - 0 views

  •  
    These are heady times for the thin-film solar industry. The sector's dominant player, First Solar, has been on a tear of late, recently announcing it would build a second 10 megawatt power plant in Nevada, while Miasole, once thought to be ailing, has staged an impressive comeback, raking in an eye-popping $220 million. Nanosolar has developed a new ultra-fast solar cell printer, and even giants like IBM and Applied Materials have gotten in on the game. In the face of such intense competition, how will HelioVolt, a well-funded outpost of CIGS manufacturing in Texas, fare? The company hopes a new hybrid, super fast CIGS process it has developed in collaboration with the National Renewable Energy Laboratory (NREL), which combines its patented FASST process and NREL's non-vacuum deposition technique, will help even the odds. The Austin, Texas-based company licensed NREL's non-vacuum deposition process, which allows for the quick application of liquid precursors onto a printing plate and substrate, to manufacture its solar cells with a 12.2 percent conversion efficiency at a fraction of the regular cost and in record time - under 6 minutes. Another advantage is that the substrate can be made from a variety of building materials, including glass, metals, plastics and roofing materials.

PV's "Moore's Law" Required To Drive Increased Material Efficiency - 0 views

  •  
    The road to grid parity for PV power generation will be difficult, needing five or more years to compete with utility power, unsubsidized, on a large scale, noted Mark Thirsk, managing partner at Linx Consulting, at a recent SEMI PV forecast luncheon (Sept. 18) in Santa Clara, CA Most input materials for PV production are in relative oversupply and will not constrain production, Thirsk pointed out - and for this reason manufacturers are conservative about capacity investment. In particular, his PV module production forecast (see Fig. 1, above) shows an overstep in demand in 2008. One reason for suppliers' reluctance to build capacity for entering the silicon supply chain is that it is an inefficient process. "Only about 15% of all the silicon going into the supply chain goes into the wafers, so it's a pretty wasteful and capital intensive process, so there is a lot of reluctance to build capacity," said Thirsk. Despite the efficiency challenges, Thirsk's forecast indicates that an oversupply may occur in 2009 Because >40% of PV grade silicon is lost at the wafering step, Thirsk believes this represents a significant opportunity for the right technology. Additionally, diamond wire is a potential replacement for slurry technology, but this technology is still immature. In the crystalline silicon (c-Si) value chain, Thirsk sees opportunities for optimizing mono-crystalline wafers with metal wrap technology and backside contacts; process optimization and material improvements would improve cell efficiency, and glass, wafer, backsheet, and grid improvements can enable more efficient light capture. Looking ahead, Thirsk told the audience that while thin-film technologies will enjoy strong growth "and may be more attractive to value-add materials and equipment suppliers, thin-film cell production will remain a minority share for the medium term." (see Fig. 3, below) He closed his presentation encouraging the creation of a Moore's Law type of roadmap for the PV

    June 2008\nNA Copper Mail
  •  
    Norddeutsche Affinerie AG (NA) said it is expecting at least EUR40 million of synergies each year from the takeover of Cumerio which was completed in March this year. The company said that it will benefit from the transfer of best practice between the two companies while cost savings mainly come from logistics and process optimization. NA also plans to increase production at its Cumerio smelters. The company expects further acquisition opportunities in Europe and in other parts of the world, including Asia. NA plans to expand its operations in southeastern Europe and the Black Sea region to capitalize on its strong economic growth before looking for growth opportunities outside Europe. In Bulgaria, the company currently expands copper cathode production capacity of its Pirdop smelter to 180,000 tonnes per year.
  •  
    Norddeutsche Affinerie is to invest €62.5M to increase by 60% its copper scrap recycling capacity in Lünen, Germany by 2011. The investment will double the firm's capacity to process complex copper-bearing scrap such as shreddings, powders and electrical scrap to 140,000t/y, bringing total scrap recycling capacity up to 350,000t/y from 220,000t/y currently. The scrap will be processed into copper cathode. The investment will see the installation of a second smelting furnace, and a waste gas purification plant in Lünen. Norddeutsche's current secondary smelter in Lünen uses a range of scrap, whilst its Hamburg plant uses copper concentrate and a small percentage of high-grade scrap. Electronic scrap availability has increased in Europe as end-of-life regulations have been introduced for its disposal.

3-D laser sintering technology creates possibility of significant weight savings in air... - 0 views

  • More than 50 percent weight savings in aircraft construction is now possible using hypermodern production techniques. A process called 3-D laser sintering of the raw material permits a completely new kind of fabrication. This process can reduce aircraft component part counts and improve designs, leading to enormous savings in weight and volume. The only equipment for this process in Austria - and at its time the second in the world - is located at FOTEC in Wiener Neustadt. The research subsidiary of the University of Applied Sciences located there is presently optimising the monitoring and quality control of the production process, while manufacturing a fuel collector for an aircraft engine that is even around 75 percent lighter than before.

Nanowire lawns make for sheets of image sensors - 0 views

  •  
    Growing a mixed "lawn" of two kinds of nanowires can make a new kind of light-sensing array that could be made in metre-scale sheets. The researchers behind the prototype say such cheap, high-quality image sensors would allow uses not conceivable using today's more expensive technology. Current sensors, such as those found in digital cameras, are made like any other silicon chip - they are carved out from a block of material. The new nanowire sensors are instead built from the bottom up, using chemically-grown nano-sized components. A research team led by Ali Javey, at the University of California, Berkeley, developed the process. They start by growing an unruly "lawn" of nanowires on a surface. The crop is then printed onto another surface, a step that simultaneously tidies them up. "At the first stage, the nanowires are more-or-less standing up, like a bad hair day. But during the printing process, they effectively get combed," says Javey. The nanowires, which are a few tenths of a millimetre long and a few tens of nanometres wide, can be printed onto anything from silicon to plastic or paper. Whatever the surface, it must be prepared with a pattern that guides the nanowires to predetermined locations. To make the functioning sensor, two different "crops" of nanotubes are printed onto the same surface. Cadmium selenide nanowires produce electric charge when hit by light, while those made from silicon-coated germanium act as transistors to amplify that charge.

Yukon`s Carmacks copper project gets YESAB approval - 0 views

  • The Yukon Environmental and Socio-Economic Assessment Board (YESAB) has recommended that the controversial Carmacks copper mine project can go ahead, providing that the Western Copper Corporation (TSX: WRN) complies with 148 conditions to mitigate potential adverse impacts. The tiny community of Carmacks with a year-round population of 500 is still considered an important service center for mining and for transportation, a century after it was a popular rest stop for the Yukon gold rush. However, members of the Little Salmon Carmacks First Nation want Western Copper to negotiate a better environmental engineering solution as part of an Impacts Benefits Agreement with the community. Located 38km northwest of the Village of Carmacks and 192 km north of Whitehorse in the Yukon Territory, the Carmacks copper project is planned to be an open-pit operation that will yield about 14,000 tonnes of copper cathode annually. Western Copper has targeted production to begin during the fourth quarter of 2010.
  • "The Executive Committee recommends...the Project be allowed to proceed without a review, subject to specified terms and conditions, since it has determined that the Project will have significant adverse environmental and socio-economic effects in the Yukon that can be mitigated by those terms and conditions." Basically, the board reported that if the operators spend enough money and devote sufficient time environmental risks can be addressed.

Solar Cooling - 0 views

  •  
    Compared to other solar energy applications, solar cooling is a relatively new, but growing, technology. Many projects using the technology are still for the purposes of demonstration only, but a growing number of systems are being implemented all over the world for conventional use. In order to give an insight into this innovative technology, detailed information about the possible technical applications of solar cooling systems is provided in this section.\n\nPassive solar cooling, based on bioclimatic strategies such as sun protection using natural screening devices or increased cooling by using ponds or water basins o the roof or close to the external walls, is widely applied and should be the first step to take in cooling a building. Such measures are easier and less costly to implement, they decrease the need for additional cooling and, therefore, for additional energy demand (and also for investment). Sufficient insulation of the building also decreases the need for cooling, as well as for heating.\n\nIf the outcome of these measures is not sufficient in itself, a solar assisted cooling system may be an intelligent solution. In solar assisted cooling systems solar heat is used to drive the cooling process for air conditioning in buildings. Instead of using electricity, free solar thermal energy is used for cooling through a thermal-chemical sorption process.\n\n

Energy volatility reflects lack of investment in oil industry - 0 views

  •  
    Although volatility in most assets is sharply lower than it was in November, oil price volatility has continued to climb. This rise in volatility, and resulting near $30-a-barrel oil price, is reflecting the same imbalances in the energy market that $147 oil did last summer: namely inadequate investment in basic infrastructure to produce, deliver, store and distribute energy. Last summer, attention focused on shortages in production capacity. However, present underlying shortages in storage and transportation are creating massive price distortions across the energy complex. Storage and transportation capacity provides the system with a buffer to supply-and-demand shocks by allowing it to run surpluses and deficits that smooth the normal cyclical swings in prices. As global storage capacity has failed to keep pace with growth in global demand over the past three decades, this buffer has shrunk relative to the size of the market, resulting in chronically higher than normal price volatility. Once infrastructure begins to constrain the ability of the market to run imbalances, prices have to create more of the adjustment process. Electricity markets are an extreme case of this. As power cannot be stored, supply must always equal demand, leaving price as the only mechanism to force the adjustment process. Accordingly, electricity is the most volatile of all assets. Due to inadequate infrastructure investment over the past several decades, oil is looking more like the electricity markets.

Hebei Dawufeng Copper temporarily suspends wirerod production - 0 views

  •  
    Xinxing Zhunguan, a Zhejiang-based manufacturer of copper wirerod, plans to increase production at its facility to 165,000t in 2013, up by 10% from 150,000t in 2012. Despite low profitability at Chinese wirerod producers, an official at the company said Xinxing Zhunguan still plans to increase output in 2013 in order to enhance competitiveness. The company said it expects orders to be subdued in the run up to the Chinese Lunar New Year, but then expects a strong rebound after the holiday period. This is consistent with another report on 11th January from Reuters which cited several Chinese copper traders as expecting the period between now and the holiday to be quiet, followed by a strong rebound.

    Jiangsu Jiangrun Copper Co. Ltd, a large Chinese copper wirerod producer, is planning to increase production of copper wirerod to 500,000t in 2013, up from 280,000t in 2012, according to an official from the company. The official said copper wirerod demand was weak in 2012, and that the company's output fell by 68,000t from 2011. The official said Jiangsu Jiangrun has invested in a new copper wirerod project which will come online from June 2013, giving the company another 350,000t/y of capacity, which will take total capacity to 750,000t/y.
  •  
    According to a survey from Asian Metal, Chinese wirerod capacity is expected to expand by 2.78Mt in 2013. Data published with the report showed that 570,000t of new wirerod production capacity will come online in Q1, followed by another 500,000t in Q2. By the end of the year this will be joined by another 1.71Mt of production capacity. The report cited Chinese local governments' desire to expand GDP growth, as well as the intention of individual companies to grow large enough to list on stock exchanges, as reasons for the rapid expansion in capacity.

    Anhui Xinke New Material Co. will start production at a new 150,000t/y copper wirerod plant in March, according to an official from the company. The source said that the company is currently in the process of testing the equipment and producing wirerod in small quantities at the site. The official said that since starting construction of the project in November 2011, wirerod demand had become "sluggish" and that processing fees for turning cathode into wirerod had declined. In 2013, the company plans to produce 100,000t of copper wirerod after shutting its old production line which could produce 35,000t/y in early February.
  •  
    Anhui Xinke, the Anhui-based manufacturer of copper wirerod, will put its new 150,000t/y wirerod plant into operation on 1st April, according to a source from the company. The company has invested RMB1.2B (US$191M) in the facility which will operate alongside its existing 35,000t/y facility. The company said that it produced 4,500t of copper wirerod in March, up from 2,500t in February. However, the source said that wirerod trading had slowed down and that it was harder to conclude deals at the moment.
  •  
    According to an official from Chinalco Kunming Copper Co., the Chinese wirerod manufacturer, the company produced 10,000t of copper wirerod in March, up from 7,000t in February. The official said that March's output of wirerod had risen because of a week-long shutdown in February for the Chinese New Year. However, output had still fallen short of the company's 13,000t target. Chinalco Kunming plans to produce 150,000t of wirerod in 2013, utilising around 68% of its 220,000t/y capacity. According to a report from Asian Metal, the company has recently settled its long-term charges for processing 8.0mm wirerod at RMB1,150/t (US$183/t).
  •  
    Wirerod production at Hebei Dawufeng Copper has been temporarily suspended since early April in order to carry out maintenance. The company elected to halt production for a month in order to carry out equipment maintenance, owing to the currently sluggish wirerod market. Production at the plant, which has a wirerod production capacity of 100,000 t/y is scheduled to re-start in early May.

    According to a US-based cathode seller, US downstream users of copper cathode are hesitant to sign long-term contracts in 2013, believing that there will be sufficient cathode available on the market for last-minute purchases. The report also cited a downstream user as saying that he believes that absent of transport costs, premiums on annual contracts might have been lower in 2013 compared to 2012. However, the report cited the downstream user as saying he preferred to take cathode from merchants due to the "more lenient" payment terms, whereby he received 10-30 days net credit on annual deals, as opposed to cash-on-payment for spot deals.

Despite the increase in output, the company made a net loss of RMB57M in 2012 from a profit of RMB24M in 2011 (loss of US$9M from a profit of US$3.8M). Remarking on the results the company said that "uncertainties in the global economy, the euro debt crisis, plus the weak Chinese economy, has negatively impacted demand by the downstream processing sector last year."
  •  
    Talking at the annual CESCO/CRU World Copper Conference, CRU Principal Consultant Vivienne Lloyd said that up to 2Mt of copper demand could be lost over the next five years due to substitution and consolidation amongst Chinese semis producers. Lloyd said that the areas under the greatest threat from substitution are the automotive wiring harness sector and the HVAC sector. However, CRU believes that the aluminium/copper price ratio is likely to have peaked in 2012 at around 4:1, and will fall back gradually to 2017 reaching 3:1, which should relieve some of the substitution pressures.
