Changing Roles: Cultivating Perennial Weeds vs. Conventional Crops for Bio-energy Production. The Case of Cynara cardunculus
Cardoon is a perennial, very deep-rooted weed of Mediterranean origin. If cultivated it produced under practically zero costs dry biomass yields of 12-16 t ha-1 rainfed ->25 t ha-1 (with 2-3 irrigations), ie. 6-8 toe [...]
Direct Injection of Flue Gas into Coal Seams for Carbon Storage and Methane Production
Investigation into the potential for flue gases from a 2400MW coal fired power station to be injected into the nearby deep coal seams under the plant for carbon capture and storage. Directional drilling techniques will [...]
Clean Waste Tech: Anaerobic Composting in Bioreactor Landfills
The controlled bioreactor landfill has been demonstrated at progressively larger scales, now up to 300,000 tons waste in multiple cells, since 1994. The approach enables recovery of renewable methane energy from landfills to maximum potential. [...]
Catalytic Conversion of Biomass to Hydrocarbons
Virent Energy Systems, Inc.’s patented Aqueous-Phase Reforming (BioFormingTM ) process enables the economical and energy efficient use of plant based sugars to generate the many hydrocarbon products that drive the world economy. Virent’s patented catalytic [...]
Analysis of the US Fuel Ethanol Industry and Market Expectations
From humble beginnings as part of Henry Ford’s vision of an agricultural based transportation industry and a rebirth as a fuel additive, ethanol is quickly approaching a 10% share of the US gasoline market. Fuel [...]
Nano-docking stations for synfuels catalysts on carbon nanotubes
Carbon nanotubes (CNTs) represent a distinctive class of catalyst supports and provide promising scenarios for catalytic reactions including fuel synthesis. The mobility of supported catalytic nanoparticles (NPs) on CNTs typically results in agglomeration leading to [...]
Complete Microbiological Fuel Cell: A Photosynthetic Cathode Coupled to a Fermentative Anode
A completely biological microbial fuel cell (MFC), using photosynthetic growth at the cathode and yeast fermentation at the anode, has been developed and operated successfully for the first time. The photosynthetic culture, Chlorella vulgaris, was [...]
Bio Mass for CO2 Neutral Steel Production
The paper presents a process to strongly increase the efficiency of bio mass as energy source in steel production by direct use of wood chips instead of charcoal combined with a new microwave based heating [...]
Novel Membrane Technology for Green Ethylene Production
Balachandran U., Lee T.H., Dorris S.E., Scouten C.G., Marshall C.L., Argonne National Laboratory, US
Today ethylene is produced (approximately 60 billion pounds in 2005 in U.S.A. alone) by thermal cracking of ethane in presence of steam requiring substantial energy input. The equilibrium conversion is thermodynamically limited. Because of direct [...]
Methanol Production for Renewable Energy Storage and Distribution
Methanol production technology and systems are being developed to provide an economically viable fuel from a renewable energy source. Neither fossil fuel nor biological feedstock is required. The energy is principally used to extract hydrogen [...]
High Quality Biodiesel from Spent Coffee Grounds
Spent coffee grounds are proved to be a potential source for high quality biodiesel production.
Impact of Government Biotechnology Regulations on Biofuel Development
Biofuels projects involving the use of advanced biotechnology strategies may be affected by government biotechnology regulation. Transgenic plants engineered to improve biofuels feedstocks may be regulated under the U.S. Department of Agriculture’s biotechnology regulations. Genetically [...]
Clean Combustion of Liquid Biofuels in Gas Turbines for Renewable Power Generation
Many states have recently enacted renewable portfolio standards (RPS) requiring a specified percentage of the power generated to come from renewable energy sources. This has created a need to find reliable sources for renewable energy [...]
Novel Alcohol Based Diesel Fuels
Novel Alcohol-based Diesel Fuels The development of efficient engines is both economically and environmentally attractive. Diesel engines because of their higher compression ratios, burn fuel at higher temperatures and efficiencies. Thus the development of diesel [...]
Improvements in biological hydrogen production by microbial fermentations
A series of physiological and genetic manipulations that improve hydrogen yields are described. The possible improvement of yields and rates through the heterologous expression of various hydrogenases will be discussed. In initial photofermentation experiments we [...]
Integrated System Approach to Bio-fuels; Bio-refineries; Renewable Resources and Sustainable Development
Sustainable Development (SD) is a multidisciplinary system by its very nature including technological and non- technological subsystems. It requires close collaboration among all engineering specializations as well as other disciplines. The most efficient approach to [...]
Biofuels: Boom or Bust?
Corn-based ethanol has been touted by many as the panacea for America’s thirst for cheap and easy liquid energy. But this supposed cure for low-mileage woes is quickly showing itself to be yet another symptom [...]
Supporting biofuel distribution through F.A.ST. ™ on-demand, variable ratio blending with a review of climate controlled storing and dispensing of Diesel Exhaust Fluid (DEF)
Clean Emission Fluids, Inc. is preparing to present and discuss capabilities, scope and trial programs involving its F.A.ST. ™ units which support biofuel distribution and infrastructure for clean diesels. F.A.ST. ™ units enable biodiesel to [...]
NanoEnergy- Technological and economical impact of nanotechnology on the energy sector
In respect of narrowing fossil energy resources and potential side effects of climate warming carbon dioxide emissions it becomes obvious that for a sustained longterm economical prosperity a fundamental renewal of the energy sector will [...]
The Opportunity Continuum: University-Industry Partnerships for Cleantech Investment
Research universities have tremendous potential to contribute to clean technology development—but traditional university practices rarely prioritize commercialization. CU-Boulder is pioneering an approach to move clean technologies along the “Opportunity Continuum,” from research idea to commercial [...]
