  1. Biofuels: Metrics and Challenges

    Webinar

    Learn about the critical economic, environmental and social issues that will impact a biofuels project along with the technical programs that could enhance a particular project.

  2. Energy Storage: Research Directions, Applications, Limitations

    Webinar

    Energy storage technologies have recently been gaining attention, spurred on by the shift toward sustainable energy. This webinar aims to explore a sampling of energy storage research.

  3. Natural Gas Future

    Webinar

    Natural gas, at prices significantly below BTU parity with oil for a long time to come, will certainly play a pivotal role in world energy supply and will move towards becoming the premier fuel of the world economy. A significant feature of future gas prices is that they are likely to be technology driven, similar to oil prices, rather than resources driven.

  4. Effects of RTD On the Performance of NREL High-Solid Continuous Pretreatment Reactor

    ChemE On Demand Presentation (AIChE Annual Meeting, 2011)

    Dilute-acid pretreatment is one of the most advanced and widely accepted pretreatment technologies. In this study, improvement in the process was sought specifically in the area of reactor technology. NREL has developed an efficient continuous pretreatment reactor that can be operated with high-...

  5. Transitioning to Low Carbon Power Generation by Integrating Renewables with Fossil Energy

    ChemE On Demand Presentation (AIChE Annual Meeting, 2010)

    It is expected that environmental regulations will be enacted to restrict the amount of carbon emissions from today's power plants. As such, it is likely that carbon capture and sequestration (CCS) technologies will be added to both new and existing coal-fired power plants to achieve compliance...

  6. Solar Based Sustainable Energy Solutions

    ChemE On Demand Presentation (AIChE Annual Meeting, 2010)

    The recent swings in oil prices again remind us that the world's supply of fossil fuels is finite. Roughly 85% of current energy use is being met by fossil fuels. Furthermore, rapid increase in energy demand by the developing nations is leading to ever increasing use of coal, oil and natural gas...

  7. Lifetime and Efficiency Studies of Zinc/Bromine Electrochemical Energy Storage In Large Scale Renewable Energy Applications

    ChemE On Demand Presentation (AIChE Annual Meeting, 2011)

    As the world's power needs grow, the demand for power from renewable resources, such as wind or solar, is increasing. One major drawback associated with these renewable resources is that the power output is dependent on environmental factors, such as cloud cover and wind speeds. This allows the...

  8. Growth Kinetic Study of Chlorella Vulgaris

    ChemE On Demand Presentation (AIChE Annual Meeting, 2009)

    Algae are simple autotrophic organisms that produce complex organic compounds from simple inorganic molecules such as carbon dioxide using energy from light or inorganic chemical reactions. These complex organics include a substantial amount of triacylglycerol which can be readily converted into...

  9. Diurnal Cycling of Triacylglycerides in a Chlorophyte Sp.: Implications for the Production of Algal Biofuels

    ChemE On Demand Presentation (AIChE Annual Meeting, 2009)

    There is no doubt that crude oil will be depleted eventually. The concept of global warming is now well accepted. Given these twin constraints, it behooves us to find alternative fuels, especially liquid ones for transportation. Microalgae have the potential to both reduce increases in greenhouse...

  10. Dynamic Model of a Solar Thermal Transport Tube Reactor for Control Purposes

    ChemE On Demand Presentation (AIChE Annual Meeting, 2009)

    A solar thermal reactor receives concentrated solar irradiation and uses this energy to thermally convert biomass into synthesis gas (H2, CO and CO2). The operation of this reactor is affected by the presence of clouds, which act as a disturbance for this process. When clouds are partially covering...
