Providers of "Infrastructure-as-a-Service" need datacenter networks that support multi-tenancy, scale, and ease of operation, at low cost. Most existing network architectures cannot meet all of these needs simultaneously. In this paper we present NetLord, a novel multi-tenant network architecture. NetLord provides tenants with simple and flexible network abstractions, by fully and efficiently virtualizing the address space at both L2 and L3. NetLord can exploit inexpensive commodity equipment to scale the network to several thousands of tenants and millions of virtual machines. NetLord requires only a small amount of offline, one-time configuration. We implemented NetLord on a testbed, and demonstrated its scalability, while achieving order-of-magnitude goodput improvements over previous approaches. Copyright 2011 ACM.

Catacel Corp's stackable structural reactor (SSR) is a direct replacement for the loose ceramic catalyst media traditionally used in the stationary steam-reforming process by industrial plants to produce hydrogen from natural gas. The SSR is a honeycomb made from a special grade of high-temperature stainless steel foil coated with a reforming catalyst. The corrugation/flow channels in the SSR are unique. They are positioned such that conductive, convective and radiant heat from the reformer tubes is efficiently transferred to all working catalytic surfaces. This improved surface utilization results in increased capacity and/or lower system cost. By contrast, catalyst surfaces near the center of ceramic systems are difficult to heat, which compromises their effectiveness. Alternatively, the higher heat transfer of the SSR promotes lower furnace temperatures with consequent energy savings and extended tube life. The heat transfer increase gained from advanced SSR catalyst technology can enable an ≈ 25% throughput improvement from most reformers to create significant energy and capital savings in hydrogen production as well as fuel cell, biofuel, alternative energy, and solid/gas-to-liquid applications.

According to a new report from SBI Energy, infrastructure investments for the shale gas industry are growing amid rising global demand for natural gas, with current levels likely to triple by 2020 to reach 12.6 tcf. In the US, shale gas production increased at an annual rate of 48% from 2006 through 2010, reaching 4.8 tcf and representing 23% of the total US natural gas production. Shale gas processing assets are now regarded as an attractive form of investment. An increase in gas and NGL products from these shale plays over recent years has led to billions of dollars worth of investments in gas processing infrastructure. While the US market has grown exponentially over the past 5 yr, production increases are also occurring in Canada, where unconventional gas accounted for 25% of the country's natural gas production in 2010.

Renewable chemicals and advanced biofuels firm Gevo has received a $5 million grant from the USDA for the development of biojet fuel from woody biomass and forest product residues. The award is a portion of a $40 million grant presented to the Northwest Advanced Renewables Alliance, a consortium led by Washington State University (WSU). The WSU-led grant aims to address the urgent national need for a domestic biofuel alternative for US commercial and military air fleets. The NARA project envisions developing a new, viable, aviation fuel industry using wood and wood waste in the Pacific Northwest, where forests cover almost half of the region. The project will also focus on increasing the profitability of wood-based fuels through development of high-value, biobased co-products to replace petrochemicals that are used in products, e.g., plastics. Gevo expects to receive full fuel certification by 2013 from the ASTM for its biojet fuel.

A team of maintenance contractors at the ConocoPhilips Humber refinery in South Killingholme, UK, has achieved a period of 5 yr (785,550 man hr) without an incident, which led to a recordable injury. The team works for multi-disciplinary maintenance services company Hertel, which carries out a broad range of tasks across the Humber site including specialist painting, insulation, access services and scaffolding. Hertel has been working on the Humber refinery site for 8 yr and this is the seventh time in that period that a 12-mo injury free period was recorded.
