A study led by a team from Peking University has estimated that global black carbon (BC) emissions increased from 5.3 teragrams/year in 1960 to 9.1 teragrams per year in 2007 (+72%). These estimates are 11-16% higher than produced by in previous inventories, the researchers noted in a paper published in the ACS journal Environmental Science & Technology.

Over the same period, BC emission intensity—the amount of BC emitted per unit of energy production—decreased by 52% for all the regions under assessment, especially China and India.

NTSB issues recommendations on certification of Li-ion batteries and emerging technologies for aircraft

The National Transportation Safety Board (NTSB) recently issued a series of recommendations related to the evaluation and certification of lithium-ion batteries for use in aircraft systems, as well as the certification of new technology. The five safety recommendations, all addressed to the Federal Aviation Administration (FAA), are derived from the ongoing investigation of the 7 January 2013, fire event that occurred in a lithium-ion battery on a Boeing 787 that was parked at Boston Logan Airport.

7th-generation Golf GTI on sale in US; lighter and more fuel-efficient

Volkswagen of America, Inc. announced the official arrival of the new 2015 Volkswagen Golf GTI in US. The MQB-based seventh-generation of the original “hot hatch” (first introduced in the US in 1983) preserves the performance and handling style of its forebears, while being bigger—but lighter—and more powerful—but more fuel efficient—than its immediate Mk 6 predecessor.

The new GTI is also Volkswagen’s introduction of the MQB (modular transverse matrix) vehicle platform to the North American market—a significant step in standardizing, simplifying, and improving the design and creation of products across the entire Volkswagen Group portfolio. The use of the MQB also more easily supports the deployment of alternative powertrain architectures, as seen in the plug-in hybrid Golf GTE. (Earlier post.)

TransWiseway and IBM partnering to build largest connected vehicles platform in China; Internet of Vehicles

IBM is collaborating with Beijing TransWiseway Information Technology Co. Ltd. to build the largest connected vehicles platform in China. The cloud-based platform will use advanced analytics for applications that offer real-time, in-vehicle services to mobile devices, such as weather advisories, traffic alerts and alternate route suggestions.

TransWiseway teamed with IBM to design an Internet of Vehicles (IoV) platform to connect millions of trucks as well as tens of millions of devices and sensors from vehicles. Using IBM Internet of Things technologies, the trucks and vehicles are connected to the Internet as well as with each other on this single IoV platform. The new IoV platform is expected to connect with 1.5 million trucks next year and ultimately with 10 million in two to three years.

Renewable wood-based biofuels for shipping

The ReShip project, led by the Paper and Fibre Research Institute (PFI) with R&D partners Aston University (UK) and NTNU (Norway), is developing technology for producing a cost-competitive pyrolysis-oil-based multi-component fuel which meets the performance requirements of marine diesel engines. The project is partly funded by the Research Council of Norway (The ENERGIX program).

In a recently completed project, Gas Technology Institute (GTI) worked with Haldor Topsøe, Inc. on an integrated biorefinery to make renewable “drop-in” gasoline. The use of renewable gasoline could reduce lifecycle greenhouse gas emissions by approximately 92% when compared to conventional gasoline.

The almost $35-million pilot-scale project, supported by the US Department of Energy (DOE) integrated biorefineries program ($25 million from DOE, $9,771,659 cost-share), converted woody biomass into bio-derived gasoline by fully integrating and optimizing biomass gasification and syngas cleanup steps with a unique process to turn syngas into gasoline.

NHTSA calculates US motor vehicle crashes in 2010 cost $871B in economic loss and societal harm

The US Department of Transportation's National Highway Traffic Safety Administration (NHTSA) released a new study that finds the price tag for motor vehicle crashes in the US in 2010 carried a cost of $871 billion in economic loss and societal harm. This includes $277 billion in economic costs—nearly $900 for each person living in the United States based on calendar year 2010 data—and $594 billion in harm from the loss of life and the pain and decreased quality of life due to injuries.

Clariant and Siemens to introduce new sour gas shift technology for coal gasification, focus on China

Clariant and Siemens Fuel Gasification Technology will cooperate in the commercialization of a new, jointly developed sour gas shift (SGS) (sulfur removal) technology for coal gasification. The agreement appoints Clariant as the exclusive catalyst supplier for all Siemens gasification integrated SGS projects. While the collaboration covers all global projects, commercialization will focus on China—the region with the highest growth rate of coal-to-chemical projects.

DENSO develops a new low-cost fuel injection system for small motorcycles

Global automotive supplier DENSO Corporation has developed a new electronic fuel injection system for small motorcycles called DIET-FI (DENSO Intelligent Economical Technology-Fuel Injection). DIET-FI is the first fuel injection system that doesn’t use a throttle position sensor or engine temperature sensor. Rather, it uses newly developed control technologies that ensure the same fuel economy and environmental performance as conventional fuel injection systems, thus cutting costs.

In the two-wheeler segment, fuel injection systems are usually only used in motorcycles; however, in recent years there has been a growing need to apply these systems to smaller motorized bikes up to the size of 150cc that are used in emerging markets, such as China.
