US invests in Energy Frontier Research Centers | Leonardo ENERGY

    • In August, U.S. Energy Secretary Steven Chu announced the delivery of $377 million in funding for 46 new Energy Frontier Research Centers. The centers will be hosted by universities, national laboratories, non-profit organizations, and private companies. The research domains that were chosen offer a good sampling of those technologies the US Department of Energy (DOE) sees as potentially important in the energy landscape of the future. The funded projects are focussed on:


      • Improving the efficiency of photovoltaic systems; with particular projects dedicated to hybrid inorganic/organic PV cells and nanometre-sized PV cells
      • Advanced nuclear techniques
      • Carbon capture and geological storage (CCS)
      • Hydrogen, including the production of hydrogen as well as hydrogen fuel cells
      • Biomass, including energy-rich plants and the conversion of biomass into chemicals and fuels
      • Energy storage systems
      • Superconductivity (1 project)

STUDY: U.S. subsidises fossil fuels 2.5 times more than renewables — Autoblog Green

  • According to a new study that reviewed fossil fuel and energy subsidies for Fiscal Years 2002-2008 was just released by the Environmental Law Institute and discovered that the U.S. spends about two-and-a-half times as much on fossil fuels (mostly aiding foreign oil production) than it does on renewable energy.

  • It's a battle between low-carb utilities and high-carb utilities. The low-carbs complain that the high-carbs want "cash for clunkers" to keep their dirty old coal plants operating. The high-carbs say the low-carbs are trying to game the allowances market to enrich themselves.

Jim Rogers: US Leads in Nuclear Power Production - WSJ.com

  • Investing in new nuclear power plants, which produce electricity 24 hours a day and seven days a week, can be a major growth engine for our economy. Nuclear plants can be located close to growing demand centers, and next to existing transmission lines. Renewables, which produce power intermittently, must often be sited far from cities and the grid.

Strategies for reducing the carbon footprint of copper : New technologies, more recycling or demand management?

  • Existing approaches to reducing environmental impacts along the metal production and consumption chain are focused largely at the plant scale for primary production, rather than considering the whole metal cycle. As such, many opportunities for systemic improvements are overlooked. This paper develops an approach to designing preferred futures for entire metal cycles that deliver reduced carbon footprints. Dynamic material flow models in Visual Basic® are used to provide life-cycle-impact-assessment indicators, which help identify key intervention points along the metal cycle. This analysis also identifies which actors or agents along the value chain are responsible for, or can influence, behaviour which affects environmental performance. With this information, it is possible to evaluate different scenarios for transition paths to achieve reduced impact. These scenarios consider combinations of new technology, increased metal recycling and demand management strategies. A case study for the copper cycle in the USA shows that to meet a CO2 reduction target of 60% by 2050, innovative technologies for primary processing of mined ore will play a limited role, due to their increasing impacts in the future associated with mining ever lower ore grades. To compensate for this whilst meeting demand projections, recycling of old scrap would be required to increase from 18% to 80%, requiring extensive collaboration between primary and secondary producers. An alternate scenario which focuses on demand reduction for copper by 1% per year, meets the CO2 target whilst only requiring an increase in the recycling rate from 18% to 36%. Together, these suggest that there is merit in examining the 'metal-in-use' stage of the metal value chain more closely in order to achieve targeted reductions in CO2. The approach also highlights the inherent trade-offs between different aspects of environmental performance which are required when pursuing CO2 reduction targets.

Is nuclear power essential to addressing climate change and energy independence? - NewTalk

Calling climate change one of the greatest challenges ever faced by the human race, some former opponents of nuclear power have recently become its advocates, if cautious advocates. Our purpose here is not to debate climate change, but rather "Is nuclear power essential to addressing climate change and energy independence?"

Kyoto's Great Carbon Offset Swindle

  • According to David Victor, a leading carbon trading analyst at Stanford University, as many as two-thirds of the supposed "emission reduction" credits being produced by the CDM from projects in developing countries are not backed by real reductions in pollution. Those pollution cuts that have been generated by the CDM, have often been achieved at a stunningly high cost: billions of dollars (or pounds) could have been saved by cutting the emissions through international funds, rather than through the CDM's supposedly efficient market mechanism.

Carbon nanotubes outperform copper nanowires as interconnects

  • After crunching numbers for months with the help of Rensselaer’s Computational Center for Nanotechnology Innovations, the most powerful university-based supercomputer in the world, the research team concluded that the carbon nanotube bundles boasted a much smaller electrical resistance than the copper nanowires. This lower resistance suggests carbon nanotube bundles would therefore be better suited for interconnect applications.

Research

  • The price of delivered electricity will rise if generators have to pay for
    carbon dioxide emissions through an implicit or explicit mechanism. There
    are two main effects that a substantial price on CO2 emissions would have
    in the short run (before the generation fleet changes significantly).
    First, consumers would react to increased price by buying less, described
    by their price elasticity of demand. Second, a price on CO2 emissions
    would change the order in which existing generators are economically
    dispatched, depending on their carbon dioxide emissions and marginal fuel
    prices. Both the price increase and dispatch changes depend on the mix of
    generation technologies and fuels in the region available for dispatch,
    although the consumer response to higher prices is the dominant effect. We
    estimate that the instantaneous imposition of a price of $35 per metric
    ton on CO2 emissions would lead to a 10% reduction in CO2 emissions in PJM
    and MISO at a price elasticity of -0.1. Reductions in ERCOT would be about
    one-third as large. Thus, a price on CO2 emissions that has been shown in
    earlier work to stimulate investment in new generation technology also
    provides significant CO2 reductions before new technology is deployed at
    large scale.

Environmental Capital - WSJ.com : Bank of America Puts a Price on Carbon

  • Bank of America says it has decided to start factoring a cost of carbon-dioxide emissions into its decisions about whether to underwrite debt for new coal-fired plants. Specifically, the bank says it anticipates a federal cap that would require a utility to pay between $20 and $40 for every ton of CO2 its power plants emit. Today in Europe, which already has imposed caps, a permit to emit a ton of CO2 is trading at about $29.


    Bank of America’s announcement comes a week after three other big banks – Citigroup, J.P. Morgan and Morgan Stanley – announced their own “Carbon Principles” – voluntary standards those banks say will make them less likely to underwrite financing on conventional coal-fired power plants.

IGCC's Future Hinges on Workable Carbon Framework

  • One of the leading alternatives for producing clean power from coal -- Integrated Combined Cycle Gasification (IGCC) technology faces a precarious future due to rising capital costs and regulatory uncertainty. A process of gasifying coal that allows capture of carbon dioxide emissions, IGCC has tremendous potential for meeting future baseload generation demand but project momentum has slowed dramatically in 2007, according to a new study from Emerging Energy Research (EER). Despite delays or cancellations of several prominent IGCC projects in 2007, 48 projects with a combined capacity of over 25,000 MW remain in the global IGCC pipeline, according to EER.

Decarbonising our economies means redefining progress « 3E Intelligence

  • Time to dispair? Not according to Monbiot:


    We must confront a challenge which is as great and as pressing as the rise of the Axis powers. Had we thrown up our hands then, as many people are tempted to do today, you would be reading this paper in German. Though the war often seemed impossible to win, when the political will was mobilised strange and implausible things began to happen. The US economy was spun round on a dime in 1942 as civilian manufacturing was switched to military production(25). The state took on greater powers than it had exercised before. Impossible policies suddenly became achievable.
