IGCC's Future Hinges on Workable Carbon Framework - 0 views

  • 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.

Making "Renewable" Viable: Drexel Engineers Develop New Technology for Grid-Level Elect... - 0 views

  •  
    "The team's research yielded a novel solution that combines the strengths of batteries and supercapacitors while also negating the scalability problem. The "electrochemical flow capacitor" (EFC) consists of an electrochemical cell connected to two external electrolyte reservoirs - a design similar to existing redox flow batteries which are used in electrical vehicles. This technology is unique because it uses small carbon particles suspended in the electrolyte liquid to create a slurry of particles that can carry an electric charge."

Global sustainability and key needs in future automotive design - 0 views

    Environ Sci Technol. 2003 Dec 1;37(23):5414-6. Global sustainability and key needs in future automotive design. McAuley JW. Basell USA Inc., 912 Appleton Road, Elkton, Maryland 21921, USA. john.mcauley@basell.com Abstract The number of light vehicle registrations is forecast to increase worldwide by a factor of 3-5 over the next 50 years. This will dramatically increase environmental impacts worldwide of automobiles and light trucks. If light vehicles are to be environmentally sustainable globally, the automotive industry must implement fundamental changes in future automotive design. Important factors in assessing automobile design needs include fuel economy and reduced emissions. Many design parameters can impact vehicle air emissions and energy consumption including alternative fuel or engine technologies, rolling resistance, aerodynamics, drive train design, friction, and vehicle weight. Of these, vehicle weight is key and will translate into reduced energy demand across all energy distribution elements. A new class of vehicles is needed that combines ultra-light design with a likely hybrid or fuel cell engine technology. This could increase efficiency by a factor of 3-5 and reduce air emissions as well. Advanced lightweight materials, such as plastics or composites, will need to overtake the present metal-based infrastructure. Incorporating design features to facilitate end-of-life recycling and recovery is also important. The trend will be towards fewer materials and parts in vehicle design, combined with ease of disassembly. Mono-material construction can create vehicle design with improved recyclability as well as reduced numbers of parts and weight.

    Application of multi-criteria decision making to sustainable energy planning-A review S. D. Pohekar , and M. Ramachandran Birla Institute of Technology and Science (BITS), Pilani 333 031, India Received 1 December 2003;  accepted 19 December 2003.  Available online 31 January 2004. Abstract Multi-Criteria Decision Making (MCDM) techniques are gaining popularity in sustainable energy management. The techniques provide solutions to the problems involving conflicting and multiple objectives. Several methods based on weighted averages, priority setting, outranking, fuzzy principles and their combinations are employed for energy planning decisions. A review of more than 90 published papers is presented here to analyze the applicability of various methods discussed. A classification on application areas and the year of application is presented to highlight the trends. It is observed that Analytical Hierarchy Process is the most popular technique followed by outranking techniques PROMETHEE and ELECTRE. Validation of results with multiple methods, development of interactive decision support systems and application of fuzzy methods to tackle uncertainties in the data is observed in the published literature.

Cogeneration Can Slash Carbon and Costs (ENN) - 0 views

  •  
    Cogeneration of electricity and heat is one of the most promising means of using existing technologies for sustainable ends, but it is also one of the most neglected and least understood. Cogeneration can dramatically increase energy efficiency, slash carbon emissions, and save money. Using cogeneration in combination with heat-pump technology and plug-in vehicles as part of a renewable electric grid, we could say goodbye to gasoline and to coal electricity generation and have a real chance in 10 to 20 years for an 80 percent reduction in carbon dioxide emissions. This transition will not require rocket science but simply the integration of existing technologies.

U.S. Government Asks for Sustainability Reports from Contractors - 0 views

  • Did you know that if you are federal contractor and are on the General Services Administration, or GSA, schedule, you will be asked to report on your sustainability efforts?” That’s the question posed by Anca Novacovici, founder and president of Eco-Coach, an environmental sustainability consulting business, in a recent Huffington Post blog. Not surprisingly for a post titled “Federal Contractors Missing the Boat,” her answer is in the negative. She writes, “Many contractors are unaware of the federal reporting requests around sustainability.”

Resource Insights: Fossil Fuels vs. Renewables: The Key Argument that Environmentalists... - 0 views

  • It turns out, however, that what most environmentalists know about the future supply of natural gas and other fossil fuels is based more on industry hype than on actual data. And, that means that they are missing a key argument in their discussions about renewable energy, one that could be used to persuade those less concerned about pollution and climate change and more concerned about energy security: There is increasing evidence that no fossil fuel will continue to see its rate of production climb significantly in the decades ahead and so none of them is a viable "bridge fuel," not natural gas, not oil, not coal. This means that global society must leap over fossil fuels and move directly to renewables as quickly as possible. In advanced economies this leap must be combined with a program of radical reductions in energy use, reductions which are achievable using known technologies and practices.

  • But a deeper analysis requested by the Guardian shows that only one in three homes, or about 10.3m households, will see the predicted reductions in their combined bills as a result of installing one or more of the renewable energy or efficiency measures, or receiving the Warm Home Discount for low-income and vulnerable households. Meanwhile the majority of bill payers, 19.1m, will see an average increase in their bills, over and above the extra costs of rising fossil fuel prices and huge investment in the electricity grid.
