Eden Energy Reports Successful Testing of Naturally-Aspirated 6L Hydrogen-Methane Engine for India Bus Fleet; Turbo Version Under Development
Australia-based Eden Energy Limited has successfully tested a production-ready 6-liter engine that will enable India’s largest bus manufacturer, Ashok Leyland, to power buses with Eden’s low-emission Hythane blend of hydrogen-enriched natural gas (usually 20% hydrogen by volume). (Earlier post.)
The 6-cylinder 92 kW (123 hp) 2010 H06B CNG engine—developed by Ashok Leyland in conjunction with Eden’s wholly-owned US subsidiary, Hythane Company—was initially designed to meet the country’s current Bharat IV (Euro IV) mandatory emissions targets. However, the results from the calibrated control system and exhaust catalyst testing for the naturally-aspirated engine would meet Bharat V (Euro V) requirements, according to Justin Fulton, Hythane Company’s Director of Engine and Fuel Systems.
Finnish and Russian Companies Partner to Develop and Build Specialty Icebreaker to Combat Oil Spills
The Finnish companies STX Finland Oy, Aker Arctic Technology Oy, Southeast Trading Oy (SET Group), and the Russian companies OAO Sovcomflot and FSUE Rosmorport have signed a cooperation agreement for the purpose of developing and building a new generation of icebreaking and rescue vessel for oil spill combat in the Gulf of Finland under ice conditions.
With the top kill procedure having failed, BP is moving on to its next attempt: the placement of a containment cap on the Lower Marine Riser Package (LMRP). (Earlier post.) The LMRP is the top half of the blowout preventer (BOP) stack. This procedure is not intended to stop the well from flowing; it is intended to capture the flow while other procedures to cap the well are underway. The basic procedure, as outlined by BP, is to:

MIT Team Extends Use of Virus Template to Assemble Li-ion Anode Materials; Biologically Activated Noble Metal Alloys

An MIT team including Drs. Gerbrand Ceder and Angela Belcher has synthesized gold (Au) and silver (Ag) alloy nanowires as anode materials for Li-ion batteries using multiple clones of the M13 bacteriophage virus. A paper on their work was published 27 May in the ACS journal Nano Letters.
This is an extension of the work initially reported in the journal Science in 2009 of genetically manipulating the M13 virus to support the synthesis and assembly of iron phosphate cathode materials for high-power lithium-ion batteries. (Earlier post.) The researchers have also engineered the M13 virus to function as a scaffold to mediate the co-assembly of zinc porphyrins (photosensitizer) and iridium oxide hydrosol clusters (catalyst) for visible light-driven water oxidation.

Dr. Jerald Schnoor, the Allen S. Henry Chair, Professor of Civil & Environmental Engineering at the University of Iowa and the Editor of the ACS journal Environmental Science & Technology is calling on Gulf researchers to consider submitting their scientific articles about the oil spill to ES&T. Schnoor was an associate editor for the journal in 1989 following the Exxon Valdez spill, and similarly invited research articles following that disaster.
Blending jatropha biodiesel (JBD) with Fischer-Tropsch synthetic diesel (FT) results in lower CO, THC, smoke and PM emissions compared to neat FT, according to a study by researchers at the Norwegian University of Science and Technology (NTNU) published in the ACS journal Energy & Fuels.
China Daily. China’s incentive plan for private purchases of new-energy vehicles may be introduced by the end of this month and will be tested in five cities, rather than nationwide, according to a report in the Shanghai Securities News.
The Mumbai train derailment two days ago could point to a growing trend in India, according to Brian Jenkins, director of the Mineta Transportation Institute’s (MTI) National Transportation Security Center of Excellence. But it also could have serious implications for other countries. Terrorists make note of methods, taking lessons from all attempts, whether successful or not. These lessons could be applied to other systems, MTI suggests.

BP and the government team involved in the response have deemed the top kill operation attempting to stop the flow of oil from the MC252 well in the Gulf of Mexico (earlier post) unsuccessful. BP is proceeding with the Lower Marine Riser Package (LMRP) Cap option.
EnerFuel Coupling High-Temperature PEM Fuel Cell With On-board Reformer for Range Extender System for Electric Vehicles

EnerFuel, a subsidiary of Li-ion manufacturer EnerDel’s parent Ener 1, is developing a range extender system for electric vehicles that consists of a high-temperature (HT) PEM fuel cell combined with an on-board reformer. The use of the reformer in conjunction with the high-temperature 3-5 kW fuel cell would enable the use of conventional hydrocarbon fuels to recharge the batteries in the EV.
In 2008, EnerFuel developed a prototype to demonstrate the advantages of a fuel cell EV range extender. (Earlier post.) The test vehicle, equipped with a 35 kWh lithium ion battery pack, was outfitted with a 3 kW fuel cell range extender fueled by compressed hydrogen (5,000 psi tank, 20 kWhe equivalent). The range extender increased average vehicle range by more than 50% from the battery only base case, EnerFuel said.
