The innovative commercial technologies for producing propylene oxide either use chlorine to promote the oxidation of propylene or involve oxidation of other compounds. The chlorohydrin process involves the use of chlorine for epoxidation of propylene with the initial step is to synthesize the propylene chlorohydrin from propylene and chlorine and the second step is the dehydrochlorination of propylene chlorohydrin to form propylene oxide (PO). Several improved processes for PO production are based on indirect oxidation and are being deployed in newer plants. One of the approaches, the Halcon process, is based on oxidation of propylene with organic hydroperoxides. Another indirect oxidation method is based on the use of hydrogen peroxide for epoxidation in the presence of a catalyst. Catalytic tests on the silver trimers have revealed that propylene oxide, acrolein, and carbon dioxide are the dominant reaction products. Source
« Volvo Cars to launch UK’s largest autonomous driving trial | Main | Onboard Dynamics receives $3M from ARPA-E, others for innovative CNG refueling technology » Volkswagen is working with partners from industry and science on the German Federal Ministry for Economic Affairs and Energy’s SLAM research project (Schnellladenetz für Achsen und Metropolen, Fast charging network for road axes and metropolitan areas). The SLAM project has a total budget of €12.9 million (US$14.6 million) and will receive support from the Federal Ministry for Economic Affairs and Energy to the extent of €8.7 million (US$9.8 million) by August 2017. The German government designated SLAM as one of seven “flagship projects in electric mobility”. A central component of SLAM is the “Golden Test Device” prototype co-developed by Volkswagen which will be unveiled at the Hannover Messe industrial trade show. The Golden Test Device is a standardized testing device to check quickly and cost-effectively the compatibility of new electric vehicles and charging stations produced by different manufacturers. A further aim is to provide an internationally accepted testing reference for connecting electric vehicles to charging stations. Volkswagen will be showing a prototype of the device at the joint stand of the United States Department of Energy/ANL and the Joint Research Centre of the European Commission at the Hannover Messe. Volkswagen took into account all the technical requirements for vehicles and charging stations and defined various test scenarios in collaboration with national and international partners to develop the device. SLAM’s mission includes setting up a fund-based research network of up to 600 fast-charging stations to collect basic data for the research and analysis of suitable charging infrastructures according to the CCS-DC standard (combined charging system). This includes simulation and location scenarios to forecast demand for new charging stations, developing business models for site operators and a uniform access and billing system. SLAM includes the development of CCS to support charging at more than 150 kW and also takes into account conditions for private investors. Volkswagen’s project partners are the BMW Group, Daimler AG, Porsche AG, Deutscher Genossenschaftsverlag, EnBW, the RWTH Aachen University and the Institute of Human Factors and Technology Management (IAT, Stuttgart).

Deep-Sea Research Part II: Topical Studies in Oceanography | Year: 2011
A dual (adjoint) model is used to explore elements of the oceanic state influencing the meridional volume and heat transports (MVT and MHT) in the sub-tropical North Atlantic so as to understand their variability and to provide the elements of useful observational program design. Focus is on the effect of temperature (and salinity) perturbations. On short timescales (months), as expected, the greatest sensitivities are to local disturbances, but as the timescales extend back to a decade and longer, the region of influence expands to occupy much of the Atlantic basin and significant areas of the global ocean, although the influence of any specific point or small area tends to be quite weak. The propagation of information in the dual solution is a clear manifestation of oceanic teleconnections. It takes place through identifiable "dual" Kelvin, Rossby, and continental shelf-waves with an interpretable physics, in particular in terms of dual expressions of barotropic and baroclinic adjustment processes. Among the notable features are the relatively fast timescales of influence (albeit weak in amplitude) between 26°N and the tropical Pacific and Indian Ocean, the absence of dominance of the sub-polar North Atlantic, significant connections to the Agulhas leakage region in the southeast Atlantic on timescales of 5-10 years, and the marked sensitivity propagation of Doppler-shifted Rossby waves in the Southern Ocean on timescales of a decade and beyond. Regional, as well as time-dependent, differences between MVT and MHT sensitivities highlight the lack of a simple correspondence between their variability. Some implications for observing systems for the purpose of climate science are discussed. © 2011 Elsevier Ltd. Source

IPAC 2014: Proceedings of the 5th International Particle Accelerator Conference | Year: 2014
Low-energy acceleration for the LINCE project  will be achieved using a 72.75 MHz normal conducting four vanes RFQ designed to give a 460 keV/u boost for A/Q = 7 ions in about 5m. The vanes are modeled to accommodate windows for a clear separation of the RFQ modes and easy fitting to an octagonal resonance chamber. This article presents the main numerical results of the radio-frequency modeling and computational fluid dynamics (CFD). Particle tracking studies optimized for bunching and acceleration are shown as well. Copyright © 2014 CC-BY-3.0 and by the respective authors. Source

The Department of Energy (DOE) announced it will fund up to $220 million of R&D projects to modernize America’s aging power grid infrastructure over the next three years. Accompanying this, DOE released its ¨Grid Modernization Multi-Year Program Plan¨ (MYPP), a strategic blueprint that informs and guides a national R&D agenda involving a consortium of DOE National Laboratories. The Grid Modernization Laboratory Consortium (GMLC) is made up of 14 DOE National Laboratories and dozens of industry, academia, and state and local government agency partners across the country, according to a DOE news release. DOE is providing funding for an initial set of 88 grid modernization projects. While a few focus specifically on microgrids, many, if not all, of them will advance development of power technologies that could be of use to microgrid project developers, utilities and other relevant stakeholders. In addition to the recently established Microgrid System Laboratory, the Grid Modernization Program reflects the potential for a distributed, smarter energy system to meet national energy objectives such as decarbonization, energy independence, and resilience from storms and terrorist attacks. Enhancing the security, reliability and resiliency of U.S. grid infrastructure and reducing carbon emissions are among the main objectives of DOE’s grid modernization plan and the new R&D funding, Energy Secretary Ernest Moniz explained. “Modernizing the U.S. electrical grid is essential to reducing carbon emissions, creating safeguards against attacks on our infrastructure, and keeping the lights on,” Secretary Moniz was quoted as saying. ¨This public-private partnership between our National Laboratories, industry, academia, and state and local government agencies will help us further strengthen our ongoing efforts to improve our electrical infrastructure so that it is prepared to respond to the nation’s energy needs for decades to come.” A full list of the Grid Modernization Initiative projects, participating laboratories and partners, as well as additional information is available on DOE’s website. Among them, UPS, Waste Management, Burns McDonnell, Harshaw Trane, LG&E and the State of Kentucky will carry out a 2-year, $1 million ¨Industrial Microgrid Analysis and Design for Energy Security and Resiliency.¨ Also directed specifically at advancing microgrid technology, Alaska state agencies, universities and Intelligent Energy systems have banded together to form the Alaska Microgrid Partnership, which is to develop a programmatic approach and framework that provides the basis for stakeholders to reduce diesel fuel consumption in remote microgrids by at least 50 percent and improve system reliability, security and resiliency without increasing system lifecycle costs. The DOE National Renewable Energy Laboratory (NREL) is participating in 44 of the 88 initial grid modernization R&D projects. GMLC co-chair and NREL Associate Laboratory Director Bryan Hannegan highlighted how GMLC illustrates a promising new approach to leveraging the resources of DOE National Labs, academic researchers and private sector power industry participants. “The Grid Modernization Laboratory Consortium is a new way of efficiently leveraging the strengths and capabilities of America’s national laboratories to deploy new concepts and technologies that will make the grid cleaner, more productive, and more secure,¨ Hannegan stated. ¨The projects announced today are an important first step towards achieving the DOE vision of a modernized grid for the nation.” DOE has invested more than $4.5 billion in grid modernization and smart grid projects via American Recovery & Reinvestment Act funding. Those investments are paying dividends in communities throughout the nation, reducing electricity costs while at the same time improving efficiency, reliability, resiliency and security, DOE highlights. ¨In Tennessee, for example, as a result of Chattanooga’s Smart Grid Investment Grant (SGIG) project, reliability increased by 45 percent. In Georgia, an electric cooperative deployed advanced metering infrastructure under the SGIG program, and reduced its operational costs by 65 percent. Service is restored faster after weather-related grid outages and emissions have been reduced. In addition, consumers are now able to better manage their own consumption, saving money and electricity.¨ Microgrid Projects Project 8: Industrial Microgrid Analysis and Design for Energy Security and Resiliency Investigation, development, and analysis of the risks, costs, and benefits of a microgrid utilizing renewable energy systems at the UPS WorldPort and Centennial Hub facilities. Develop a roadmap to help industries evaluate microgrid adoption by defining institutional and regulatory challenges associated with development of industrial-based resilient systems. Deliver to stakeholders an integrated distributed resource planning and optimization platform, hosted online, able to identify meaningful behind-the-meter DER adoption patterns, potential microgrid sites and demand-side resources, and evaluate the impacts of high renewable penetration feeders on the distribution and transmission grid. Partners: ANL, BNL, LBNL, LLNL, NREL, SLAC, California PUC, Pacific Gas and Electric (PG&E), Southern California Ediso (SCE), Metropolitan Council of Governments, New York State Energy Research and Development Authority (NYSERDA) Improve physical security of the Idaho Falls distribution system by testing smart reconfiguration, intelligent DR utilizing loads as a resource, controlled islanding, black start procedures for emergency service, and resynchronization in the presence of DERs. Develop a design basis framework and programmatic approach to assist stakeholders in their efforts to reduce diesel fuel consumption by at least 50% in Alaska’s remote microgrids without increasing system lifecycle costs, while improving overall system reliability, security, and resilience. Three campuses (PNNL, UW and WSU) will develop and test a range of tranactive control activities on each of the 3 campuses. They will also develop the ability to coordinate across these three campuses to provide coordinated services to the PNW power system and their serving distribution utilities based upon the transactive response of key loads on the campuses. The UW will emphasize energy storage and coordination for peak management and provision of flexibility. The WSU campus will leverage its microgrid and major campus loads and thermal storage to deliver transactive response. And PNNL will advance controls in its new SEB grid building and other campus loads to help the City of Richland better manage it’s demand limits. OE and BTO collaborated in the design and cost share of the project. The post DOE Announces Grid Modernization R&D Projects, Partners, and Funding appeared first on Microgrid Media.
