CSIRO Energy Technology (Newcastle, New South Wales, Australia; www.csiro.au) is developing a solar-powered air conditioning unit for residential use, using a desiccant-evaporative process to provide cool and dehumidified air. Thermally driven ab- or adsorption chillers are commonly used to provide cooling using heat, but these entail disadvantages: they are expensive, bulky, they produce chilled water...

A photocatalyst that is more active for decomposing volatile organic compounds (VOCs) with visible light than existing catalysts has been developed by researchers from the New Energy and Industrial Technology Development Organization (NEDO; Kawasaki City, Japan) in a project lead by professor Kazuhito Hashimoto at the University of Tokyo. The catalyst — a copper ion supported tungsten oxide —...

Last month, GE Oil & Gas (Florence, Italy; www.ge.com/oilandgas) received a contract to supply Eni S.p.A. (Rome; www.eni.it) with the largest refinery reactors of their type ever to be manufactured. GE Oil & Gas’ components-production facility in Massa, Italy, will manufacture the heavy-wall, slurry reactors — each weighing about 2,000 tons — and then transport them to Eni’s...

Bioethanol Ethanol from plant and forestry waste and dedicated energy crops could replace approximately one-third of U.S. gasoline requirements by 2030 on a sustainable basis, according to a study by Sandia National Laboratories (Livermore, Calif.; www.sandia.gov) and General Motors Corp. (Detroit, Mich.; www.gm.com). The researchers found that 90 billion gal of ethanol could be produced annually by 2030...

In these hard economic times, people working in troubled businesses may well envy the situation of Alberta’s oil sands industry. The Canadian Association of Petroleum Producers (CAPP, Calgary, Alberta; www.capp.ca) predicts that the production of synthetic crude from oil sands will reach 3.3-million bbl/d by 2020, up from 1.2-million bbl/d in 2007. Much of this oil will be sent to the U.S. via an...

Globally, water reuse and recycling are not uncommon — with parts of Australia, South Africa and the Middle East rather heartily embracing the practice. Even in Europe, it is estimated that 75 to 80% of water is reused. However, because fresh water is prevalent and plentiful in most parts of the U.S., few domestic chemical processors, or other industrial consumers of water, have yet to take the...

Thanks to a €171-million financing deal, construction can begin on what is claimed to be the world’s first utility-grade solar power plant with central tower and salt receiver technology. When the so-called Gemasolar plant — located in Fuentes de Andalucia, Spain — is operational in 2011, it will produce 17 MWe of power, reducing CO2 emissions by more than 50,000 metric tons per year...

A continuous process for producing biodiesel that has a residence time of about one minute, versus several hours for a conventional batch process, has been developed at Oak Ridge National Laboratory (ORNL; Oak Ridge, Tenn.; www.ornl.gov). The process uses a centrifuge for simultaneous synthesis of biodiesel and separation of the biodiesel from the glycerol byproduct. ORNL has done laboratory tests and is...

Mitsunori Shimura and colleagues at the R&D Center of Chiyoda Corp. (Yokohama, Japan; www.chiyoda.co.jp) have developed a new catalyst for producing a synthesis gas (syngas; hydrogen and carbon monoxide) from steam reforming of methane. The catalyst consists of precious metals selectively loaded on the surface of the firm’s commercial, egg-shell-shaped support, which results in an effective...

Lurgi GmbH (Frankfurt, Germany; www.lurgi.com) is building a pilot plant to demonstrate the viability of its three-stage bioliq process for producing liquid fuels from biomass. The pilot plant — an entrained-flow gasifier for the production of synthesis gas — will be located at the Karlsruhe Research Center (FZK; Germany; www.fzk.de), and is part of a joint project with the Karlsruhe Institute of...

For separating two components with similar volatilities, extractive distillation is typically used, whereby a high-boiling, non-volatile solvent is added to "break the azeotrope" — a process that is both energy intensive and often involves the use of hazardous solvents. In an effort to reduce the energy requirements and avoid the use of hazardous solvents used in extractive distillation, an...

Ultrasound has been applied, with limited success, for the remediation of contaminated soil. Up to now, the approach has been to first extract the contaminant from the soil into a liquid, which is then passed through a sono-reactor where the contaminants are destroyed by high temperatures and pressures (more than 5,000K and 1,000 atm) generated by cavitating bubbles. A new process developed by a team from...

In a so-called thermoacoustic engine, researchers from the Energy Research Center of the Netherlands (ECN; Petten, Netherlands; www.ecn.nl) have achieved a record efficiency in the conversion of heat to sound, improving the existing record of 41% to 48% of the maximum possible efficiency (Carnot efficiency). The engine is being developed as a way to utilize the huge quantities of waste heat, which normally...

A new bioplastic Up to now, the main plastic produced from renewable resources has been polylactic acid (PLA), which is derived from corn starch. However, because PLA does not have the same level of performance as petroleum-derived plastics, PLA has not been actively adopted by certain industries, according to Teijin Ltd. (Tokyo, Japan; www.teijin.co.jp/english). The company plans to change this situation...

As an energy resource, global coal reserves represent 2,000 billion barrels of oil equivalent. In 2007, global oil reserves were about 1,300 billion barrels of oil. World wide, oil demand will grow 40 to 50% by 2030. But coal offers an opportunity to diversify worldwide liquid-fuel supplies and coal utilization to produce fuels that can extend the lifetime of world oil reserves. This is a strategic...
