ArcelorMittal Launches Cleantech and Carbon Funds - 0 views

  •  
    ArcelorMittal (NYSE: MT), a steel manufacturer based in New Deli, launched a clean technology venture capital fund to support ventures that have relevance for the carbon-intensive steel industry. The Fund has made its first investment of US$20 million in Miasolé, a California-based pioneer in the development of thin-film solar panels Miasolé has developed unique high volume manufacturing processes that enable efficient production of Copper Indium Gallium Selenium (CIGS) solar products on a flexible stainless steel substrate. This technology promises to dramatically lowers the installed cost of Photovoltaic (PV) systems and will enable renewable energy from the sun to replace carbon generating fossil fuels. Fund managers will be working with leading venture capital firms, including Bessemer Venture Partners, Khosla Ventures, and Kleiner Perkins Caufield & Byers, to identify worthy cleantech ventures. ArcelorMittal also announced that it has created a new carbon fund in order to strategically engage in the carbon market and promote climate friendly solutions that are relevant for the steel industry. The fund, which has an initial investment commitment of €100 million (US$ 157 million) is currently looking at investment opportunities in renewable energy, energy efficiency, methane capture and greenhouse gas reducing technologies--all of which have the potential to generate carbon credits under the Kyoto Protocol. ArcelorMittal intends to use the carbon credits received from these Clean Development Mechanism and Joint Implementation projects for compliance in the EU Emissions Trading Scheme.

Japanese Companies Developing Carbon Fiber Cars - 0 views

  •  
    Two Japanese companies are working together to develop carbon fiber materials for use in cars, according to a Reuters report. Toray Industries (3402.T) and Mitsubishi Rayon (3404.T) hope to mass produce the lightweight material by 2010 in an effot to make vehicles 40% lighter and up to 30% more fuel efficient. They also intend to develop technology to recycle carbon fiberin order to bring costs down. For years, proponents of carbon fiber materials have supported its widespread use in vehicles, but the cost of the highly engineered materials was prohibitive. Now with gasoline and steel prices on the rise, carbon fiber is becoming more economically feasible. The Nikkei business daily reported that Nissan Motor Co. and Honda Motor Co. were participating in the partnership, along with Toyobo Takagi Seiko Corp and researchers from the University of Tokyo. However, both Nissan and Honda denied that they were participating in the project. A spokeswomam for Japan's New Energy and Industrial Technology Development Organization said teh government is also researching the further use of aluminum and other light-weight metals to replace steel.

End of easy carbon trading? - 0 views

  •  
    LONDON, UK, August 12, 2008. Analyst New Energy Finance says the days of easy carbon trading may be over as the low hanging fruit of the cheap carbon credits in the developing world have now been harvested. To date, the cheapest way of reducing greenhouse gas (GHG) emissions have come from projects eliminating high global warming potential (GWP) gases in developing countries, notably China. These projects involve the destruction of two waste gases from industrial facilities: the hydrofluorocarbon HFC-23 and nitrous dioxide, or 'laughing gas' (N2O), both of which are several thousand times more potent in terms of global warming that CO2. The size of the emissions reductions achievable from these projects relative to the scale of the investment required, that these carbon credits are so cheap - around €1/tCO2e. In comparison, costs claimed by project developers of renewable energy and energy efficiency projects are €5-15 per tonne and the global market price for carbon countries from developing countries are around €20/tCO2e.

Graphene Overtaking Carbon Nanotubes - 0 views

  • Carbon Nanotubes (CNTs) have not yet met commercial expectations from a decade ago, and now hot on its heels is graphene. Graphene is considered a hot candidate for applications such as computers, displays, photovoltaics, and flexible electronics. IDTechEx market forecasts indicate that CNT and graphene transistors may be commercially available in volume from 2015 onwards, according to the new report \"Carbon Nanotubes and Graphene for Electronics Applications 2011-2021\". According to IDTechEx, the biggest opportunity for both materials is in printed and potentially printed electronics, where the value of these devices that partly incorporate these materials will reach over $44 billion in 2021.

Nexans' innovative overhead line technology helps Brazil solve electricity transmission... - 1 views

  • Resulting from a five-year development programme involving Nexans’ technology centres in France and Belgium, this innovative overhead line technology consists in a thermal resistant aluminium conductor wrapped around a composite carbon core. Compared with a traditional ACSR (Aluminium Conductor Steel Reinforced) which uses steel core, the composite carbon core of the same diameter is much lighter and 50 percent stronger. Most importantly, the carbon core’s coefficient of thermal expansion is roughly one tenth of that of steel, so it expands (and ‘sags’) much less when heated by the high current flowing in the conductor, enabling the vital safety clearances to be maintained between the conductor and the ground, even at high operating temperatures.

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

This technology seems to me to be much more beneficial on a local scale, what if every home had its own battery, then home power generation becomes economically more viable for everyone. If you could show that a system like this could pay for itself in say 5 years then every home would want one. Plus for this to be implemented on a large scale requires massive investment that could be decades away. Share the technology and lets get it in homes by next year. Great ted talk. Jon Senior 0 Reply 1 hour ago: I agree 100%. Localised energy production would also make energy consumers more conscious of their consumption and encourage efforts to reduce it. We can invent and invent all we want, but the fast solution to allowing renewable energies to take centre stage is to reduce the base energy draw. With lower baseline consumption, smaller "always on" generators are required to keep the grid operational. Town and house-l

  •  
    the most detailed popular discussion of geo-engineering I have come across so far. In broad terms three possible techniques were identified:\n\n* Removing carbon dioxide from the oceans.\n* Removing carbon dioxide from the atmosphere.\n* Using lenses or mirrors to divert sunlight from the planet.\n\nHowever, the discussion is still wracked with anxiety. On the one hand, some are arguing that things are getting so bad that geo-engineering might be necessary despite the possibility of damaging unintended consequences. On the other hand, others are worried that discussing geo-engineering could shift the discussion away from decarbonisation. An added worry seems to be that developing countries such as China and India - those that most need great increases in energy supply - could take a lead in developing the technology.\n

    the top 4 contenders are: 1. Green building materials - I'm not sure it would be my thing, but investors across the board seem to think this area is ripe for a hit. 2. Carbon IT - With some sort of cap and trade a near certainty, the interest is picking up in one of the few areas in carbon that looks like a "venture bet". I should know, I have one of these companies myself. 3. Food related technologies - High food prices and rising fertilizer costs, what can I say? 4. N-generation solar technologies - Everyone not in the first wave is looking to get in to the 4th wave. Not sure venture investors will fare better in the 3rd or 4th wave than they did in the second, but they are going to try.

Electricity industry looks to a green electric future - 0 views

  • Carbon capture and storage remains a nascent technology: no one has yet proved that an integrated process can work on a commercial scale. But the US, Canada, Australia, the European Union and others have pledged billions of dollars to back demonstration projects. This suggests commercial deployment could be possible around 2020.Even so, any transition to carbon-free generation will take decades. Low-carbon technologies are generally more expensive than fossil-fuel plants: some, such as offshore wind, are a lot more expensive. And with wind, power generation will not be constantly available. Britain, which is backing Europe's fastest expansion of wind power, is building into its plans for 2030 a huge margin of spare generation capacity which can be used when there is no wind.
