A new era for commodities - McKinsey Quarterly - Energy, Resources, Materials - Environ... - 1 views

  • A new era for commodities
  •  
    A new era for commodities Cheap resources underpinned economic growth for much of the 20th century. The 21st will be different. NOVEMBER 2011 * Richard Dobbs, Jeremy Oppenheim, and Fraser Thompson Source: McKinsey Global Institute, Sustainability & Resource Productivity Practice In This Article Exhibit: In little more than a decade, soaring commodity prices have erased a century of steady declines. About the authors Comments (2) Has the global economy entered an era of persistently high, volatile commodity prices? Our research shows that during the past eight years alone, they have undone the decline of the previous century, rising to levels not seen since the early 1900s (exhibit). In addition, volatility is now greater than at any time since the oil-shocked 1970s because commodity prices increasingly move in lockstep. Our analysis suggests that they will remain high and volatile for at least the next 20 years if current trends hold-barring a major macroeconomic shock-as global resource markets oscillate in response to surging global demand and inelastic supplies. Back to top Demand for energy, food, metals, and water should rise inexorably as three billion new middle-class consumers emerge in the next two decades.1 The global car fleet, for example, is expected almost to double, to 1.7 billion, by 2030. In India, we expect calorie intake per person to rise by 20 percent during that period, while per capita meat consumption in China could increase by 60 percent, to 80 kilograms (176 pounds) a year. Demand for urban infrastructure also will soar. China, for example, could annually add floor space totaling 2.5 times the entire residential and commercial square footage of the city of Chicago, while India could add floor space equal to another Chicago every year. Such dramatic growth in demand for commodities actually isn't unusual. Similar factors were at play throughout the 20th century as the planet's population tripled and demand for various resource

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.

Superconductor cables giving LIPA energy efficiency - 0 views

  • It looks ordinary, like a razor-thin metal ribbon. But the high-temperature superconductor power transmission cable the Long Island Power Authority recently installed in Ronkonkoma revolutionizes how electricity is delivered, utility and federal officials said.
  • The cable -- which is a fraction of the size of a traditional copper wire but can carry three times the power -- made its ceremonial debut yesterday with officials from LIPA, the U.S. Department of Energy and officials from the company that makes the cable. It went online April 22, the world's first use of the new technology in a commercial power grid. Utilities around the world are looking at superconductivity to improve efficiency of their grids and make them less vulnerable to blackouts. LIPA has buried three 2,000-foot wires in its right-of-way, and it will be installing a second generation of the wire in the same area as a test.
  • The wire, manufactured by American Superconductor Corp., conducts 150 times the electricity of the same sized copper wires, strand-for-strand. This means transmission cables can be far smaller and still conduct as much as three to five times more power in a smaller right-of-way. When operated at full capacity, the 138-kilovolt cable LIPA uses is capable of transmitting up to 574 megawatts of electricity, enough to power 300,000 homes. The Department of Energy has funded $27.5 million of the $58.5 million cost of the project as part of its effort to spur creation of a modern electricity superhighway free of bottlenecks and that transmits power to customers from remote generation sites such as wind farms.

  • Superconducting technology relies on a phenomenon first identified in 1911. When chilled sufficiently by a recirculating coolant -- liquid nitrogen in LIPA's case -- superconducting material loses virtually all resistance to the flow of the alternating current used in a commercial power grid.

    US speciality brass mill Ansonia Copper and Brass Inc. has announced that it will lay off 85 of the 102 employees at its Liberty Street, Ansonia, factory in Connecticut. The plant manufactures copper alloy rod and wires. Company President Raymond McGee said "it's a very, very difficult situation". He blamed the redundancies, on top of 76 employees laid off in April 2007, on the company's struggle with escalating costs. Since 2002 electricity costs have soared 239%, natural gas 200%, fuel oil 125%, and copper and nickel 500% apiece. Ansonia's other facility in Waterbury, CT, which manufacturers copper alloy tube is unaffected by the announcement.

    In the past few days world leading cablemaker Nexans has announced one acquisition, one new joint venture and one asset disposal. On the 30th May, Nexans acquired Intercond a leading Italian manufacturer of special cables for industrial equipment and subsea applications. The company had sales of €90m and employs 150. "This [€90m] acquisition fits totally in the Group's strategy by increasing the proportion of its business in high value-added special cables", said Gerard Hauser, Chairman and CEO of Nexans. On the 2nd June, Nexans released a press report confirming that it has formed a joint venture to create a wire and cable plant in Qatar, the country's first manufacturing facility. Qatar International Cable Company (QICC) is owned 29% by Nexans with the balance being owned by Special Projects Company and Al Neama Industrial Co. The new plant in the industrial city of Mesaleed, 40km from Doha, and will employ 210 people. By the end of 2009 it will begin manufacturing low and medium voltage cables for buildings and energy infrastructure as well as special cables for the oil and gas industry. This JV will generate sales of $150m per year by 2010 at current copper prices. Finally, Nexans confirmed that it has completed the pre-announced sale of its copper telecom cable plant at Santander in Spain to the British company B3 Cable Solutions for €17m. These three actions continue to refocus the group's strategy on priority market segments.

    Turkish copper semis producer Sarkuysan expects its output of copper products (wirerod, wire, tube and billet) to rise from 185,000 tonnes in 2007 to around 200,000 tonnes in 2008. According to the General Manager Hayrettin Cayci, "The market is forcing us to increase production as demand, particularly in Turkey, is very healthy", adding that demand came mainly from a Turkish property construction boom. "There's a big boom in demand for energy cables. Plus developed European countries have pulled away from cable production and they're mainly supplying from countries like Turkey". However, high copper prices have eroded profit margins so the company is focussing on more higher value products. He expected total Turkish copper demand (refined and scrap) to rise above 500,000 tonnes this year, from 450,000 tonnes now, and by 2010 he expected demand would reach 600,000 tonnes. Refined copper consumption is currently around 300,000 tonnes.

    The Exsym Corporation, the joint venture between SWCC Showa Holdings and Mitsubishi Cable Industries, has announced plans to expand its exports of ultra high voltage cables to the Middle East and South East Asia. In order to meet this increase in demand, a horizontal sheathing line has been transferred to the company's Aichi plant in Japan. This will bring the number of sheathing lines for ultra high voltage cables at the plant to three, once the transferred line begins commercial operation over the summer. Exsym also plans to renew one of the two conductor stranding lines at the Aichi plant with the new line expected to begin commercial operation in November 2008. With these new lines as well as an increased number of construction staff, copper cable capacity at the plant is expected to grow by around 200 tonnes per month to 1,200 tonnes per month. In the fiscal year 2007, Exsym posted revenue of ¥41 billion ($0.39 billion) with an operating profit of almost ¥2 billion ($0.02 billion). Exports of ultra high voltage cables to the Middle East and South East Asia accounted for around 40% of the total revenue. The company expects the increase in export capacity to increase revenue to ¥43 billion ($0.41 billion) per year by the end of the fiscal year 2010.

    Mitsubishi Shindoh is to invest Yen6-7 billion to expand production of copper strips at its Sambo plant in Osaka, Japan. This will increase capacity from 3,200 tonnes per month (tpm) to 4,200tpm by March 2010. In addition, the company will transfer 800tpm of copper strip production from its plant in Wakamatsu, Fukushima, Japan, bringing total production capacity to 5,000tpm. Mitsubishi Shindoh will also spend Yen6 billion to improve its copper alloy strip capabilities at its Wakamatsu plant. Productive capacity will remain at 6,500tpm, but with an increased ratio of high quality products. As a result, total company capacity will grow by 40% to 11,500tpm. Mitsubishi Shindoh is a copper and copper alloy fabricator within the Mitsubishi Materials Group. Japan mills have recently seen a strong growth in orders from the semiconductor, leadframe, connector and automotive industries, and clearly expect this to continue.

    Hindalco Industries and Sterlite Industries - the two privately owned Indian copper smelter/refinery/rod producers - are considering changing their domestic pricing mechanism for copper due to the dramatic rise in oil prices. At present, a uniform pricing system for customers all over the country is in place, however, the companies are mulling a change to ex-works pricing. This would mean that customers would be charged a different price depending on their delivery destination from the smelter. To balance the recent hike in fuel prices, they had recently started levying a Rs2/kg freight charge across the country irrespective of distance. Diesel is used in firing the furnaces while furnace oil is used in running them. The total fuel cost is estimated at 10-12% of the price of copper, with 1% of this being the transportation cost. The fuel price hike has not affected domestic copper demand as yet, but a prolonged period of this sentiment may hit many developing infrastructure projects badly.

    Jiangxi Copper said it expects Chinese refined copper consumption to grow at 8-10% this year driven by investment in the power industry. Power generation accounts for between 50-60% of all copper used in China. Damage to power generation capacity caused by this year's earthquake in Sichuan province will require a major rebuilding program which will also stimulate copper consumption. Chinese refined copper imports fell by 23% year on year between January and April, however, this decline was at least partly explained by a 23% expansion in Chinese refined copper production during the period. Wu Yuneng, General Manager of JCC Southern Copper said, "We need more concentrate and scrap rather than refined copper".

    Four major Japanese copper tube producers plan to reduce production by 4% year-on-year to 84,220 tonnes in total during the first half of the fiscal year 2008 (April 07-March 08). It is reported that demand for copper tubes has fallen because of the inactive construction industry as well as high copper prices. The construction industry saw a major slowdown last year after the introduction of new building regulations. All four producers expected this weak trend to continue. Sumitomo Light Metal is the only producer who plans to increase its output estimate, but only by 1% year-on-year. Kobelco & Materials Copper Tube says that it would decrease normal tube output for export to adjust the inventory level at its Malaysian operation. Furukawa Electric and Hitachi Cable said they would need to focus more on their commercial tube businesses. It is believed that the tube market has also been hit by substitution from aluminium.

    Luvata's ECO-Heatcraft division has launched a new technology for its air conditioning and refrigeration systems based upon using carbon dioxide as a refrigerant. The company believes that, as well as offering zero ozone depletion and less effect on global warming, the use of carbon dioxide can also allow more efficient operation of the system than traditional refrigerants. Luvata claims that, "The higher volumetric efficiency of carbon dioxide (known as R744) means that the cross sectional area of pipes used in heat transfer equipment can be reduced. As a result, equipment has the potential to be smaller, lighter, more efficient and better for the environment". The development of smaller diameter pipes with reduced wall thicknesses would tend to favour existing inner grooved copper tube based designs rather than emerging aluminium based technologies.

    Further evidence of the impact of the North American economic slowdown on copper demand has recently been published by the ABMS and government statistical bodies. North American copper wirerod production plummeted 9.6% year-on-year to 174,000 tonnes in April. Output had been on a downward trend but the magnitude of the deterioration in April has still come as something of a surprise. A year-on-year increase of 2.0% in North American output January had been followed a 1.0% fall in February and a 2.7% drop in March. In April Canadian output was flat year-on-year due to improving export sales to the US, while US production fell 9.8% year-on-year and Mexican shipments slumped by 17.5%. On a year-to-date basis North American wirerod production was 2.9% lower in the four months to April 2008. Weakening demand from the automotive industry, coupled with a resurgance in copper prices and the return of Russian wirerod imports has clearly led to a deteriorating market situation for domestic mills.

    Mueller Industries second quarter results highlight the tough times that the US brass mill industry is facing, but that companies can still operate profitably in a challenging market environment. The company's plumbing and refrigeration segment saw sales fall 11% to US$404m, while its operating profits dropped 32% to US$35m. The company blamed lower shipment volumes and lower spreads for the weaker performance. Sales at the company's OEM division, which includes its brass rod activities, rose 10% year-on-year to US$354m, while its operating profits rose 5% to US$19m. The improvement here is due to acquisition of Extruded Metals. Commenting on the results Harvey Karp, Chairman of Mueller Industries said "Mueller's earnings for the first half of 2008 were achieved despite the continuing decline in the housing industry, the sub-prime mortgage meltdown, the turbulence in the financial markets, rising metal costs, sky-high energy prices and a slowing national economy. Considering these adverse circumstances, we are pleased with the results."

EERE News: Superconducting Cable Project Points to More Efficient Grid - 0 views

  • DOE and SuperPower, Inc. commemorated on February 21 a $27 million project to install a 350-meter high-temperature superconducting (HTS) cable between two electrical substations in Albany. While that might not sound like much cable for the money, the project is the first demonstration of a technology that could someday be used to build a more energy efficient power grid. The HTS cable reduces energy loss by up to 10%, and wires using the same technology could potentially be integrated into generators, transformers, cables, and fault current limiters, making most of the equipment that produces and delivers power more energy efficient. On the other end of the power line, HTS wires can be employed in motors, providing an energy efficiency improvement for one of the largest electrical loads served by electric utilities.

Assessing the performance of energy efficient buildings - 0 views

  •  
    "What are the most important key performance indicators? There are, for example, indicators defining the temperature changes in reference rooms. This includes what is referred to as hours of overheating in summer. If the room temperature exceeds 26 degrees Celsius during more than 10 percent of the hours of use during a year, the room comfort is no longer achieved. Other indicators measure air quality. For example, there are CO2 sensors or so-called VOC-sensors that detect certain scents emitted by the users themselves. If the data exceed certain values, the performance in terms of air quality is not considered as good. In addition, there are energy performance indicators, such as an indicator for the overall energy efficiency of a building. We simply measure the energy that is supplied to the building. We then compare the data to pre-calculated values. We can then evaluate whether the building achieves the desired energy performance. Another indicator is the so-called net energy consumption. This is the energy that users actually have to pay for. "
