OSU smart membrane could enable new category of high-energy, high-power energy storage for EVs

24 August 2016

A team at the Ohio State University has developed a membrane that regulates bi-directional ion transport across it as a function of its redox state and that could be used as a programmable smart membrane separator in future supercapacitors and redox flow batteries.

Described in a paper published in the RSC journal Energy & Environmental Science, the smart membrane separator could enable the design of a new category of rechargeable/refillable energy storage devices with high energy density and specific power that would overcome the contemporary limitations of electric vehicles.

Opel introducing Ampera-e at Paris Show; European cousin of Chevy Bolt

24 August 2016

Opel will introduce the Ampera-e at the upcoming Paris Motor Show in September. Ampera-e is the European cousin to the Chevy Bolt (earlier post), as the Ampera was to the Chevy Volt.

In the run-up to the world premiere, Opel is touting the performance of the battery-electric vehicle. With maximum torque of 360 N·m from the 150 kW electric motor, the compact car accelerates from 0 to 50 km/h (31 mph) in 3.2 seconds; acceleration from 80 to 120 km/h (50 to 75 mph) for overtaking in 4.5 seconds (provisional figures). The Ampera-e thus performs at the same level as OPC models, the sporty spearheads of Opel.

MIT team calculates lead emissions from avgas fuel in US contribute to ~$1B in annual damages due to IQ losses

24 August 2016

Researchers at MIT have produced the first assessment of the annual costs of IQ losses from aircraft lead emissions in the US. Their study, published in the ACS journal Environmental Science & Technology, found that that atmospheric lead pollution attributable to leaded aviation gas (avgas) contributes to US$1.06 billion (the mean from a range of $0.01–$11.6 billion) in annual damages from lifetime earnings reductions, and that dynamic economy-wide methods result in damage estimates that are 54% larger.

Because the marginal costs of atmospheric lead pollution are dependent on background concentration, the researchers also expect the costs of piston-driven aircraft lead emissions to increase over time as regulations on other emissions sources are tightened.

New LANL membrane bridges operational gap between low- and high-temperature PEM fuel cells; potential for lower cost systems

23 August 2016

A Los Alamos National Laboratory team, in collaboration with Yoong-Kee Choe at the National Institute of Advanced Industrial Science and Technology in Japan and Cy Fujimoto of Sandia National Laboratories, has discovered that fuel cells based on a new phosphate-quaternary ammonium ion-pair membrane can be operated between 80 °C and 200 °C with and without water, enhancing the fuel cells’ usability under a range of conditions. The research is published in the journal Nature Energy.

These fuel cells exhibit stable performance at 80–160 ˚C with a conductivity decay rate more than three orders of magnitude lower than that of a commercial high-temperature PEM fuel cell. By increasing the operational flexibility, this class of fuel cell can simplify the requirements for heat and water management, and potentially reduce the costs associated with the existing fully functional fuel cell systems.

NVIDIA dives into Parker mobile processor for next generation of autonomous vehicles

23 August 2016

Speaking at the Hot Chips conference in Cupertino, California, NVIDIA revealed the architecture and underlying technology of its new Parker processor, which is suited for automotive applications such as self-driving cars and digital cockpits. Hot Chips, a symposium on high performance chips, is sponsored by the IEEE Technical Committee on Microprocessors and Microcomputers in cooperation with ACM SIGARCH.

NVIDIA mentioned Parker at CES 2016 earlier this year, when it introduced the NVIDIA DRIVE PX 2 platform (earlier post). That platform uses two Parker processors and two Pascal architecture-based GPUs to power deep learning applications.

Mobileye and Delphi to partner on SAE Level 4/5 automated driving solution for 2019

23 August 2016

Mobileye and Delphi Automotive PLC are partnering to develop a complete SAE Level 4/5 automated driving solution. The program will result in an end-to-end production-intent fully automated vehicle solution, with the level of performance and functional safety required for rapid integration into diverse vehicle platforms for a range of customers worldwide.

The partners’ “Central Sensing Localization and Planning” (CSLP) platform will be demonstrated in combined urban and highway driving at the 2017 Consumer Electronics Show in Las Vegas and production ready for 2019.

Daimler-BYD JV introduces new DENZA 400 EV for China; up to 400 km on full charge

23 August 2016

Daimler has extended its portfolio of new energy vehicles (NEV) with the introduction of the DENZA 400, the company’s “Made in China, for China” electric vehicle from joint venture Shenzhen BYD Daimler New Technology Co., Ltd. (BDNT).

The DENZA 400 features improved battery density achieved through an upgraded production process that increases the battery’s capacity from 47.5 kWh to 62 kWh while maintaining the original size. With an upgraded range of up to 400 km (249 miles), most Chinese consumers, who generally drive 50 to 80 km per day, will only need to recharge their DENZA 400 once per week.

Zhejiang University team investigates emissions from methanol-gasoline blends

23 August 2016

Globally, the use of methanol as an alternative fuel has attracted interest because of its low production cost, renewable capacity, and good combustion-related properties (higher thermal efficiency, higher engine power, and lower regulated emissions). In China in particular, there are abundant coal resources, and the technology of using coal to obtain methanol has been perfected with low cost; methanol fuel from coal has become one of the most popular alternative fuels for vehicles.

However, the in-cylinder combustion of methanol also produces a considerable amount of extra toxic emissions, such as alcohols and aldehydes. A team at Zhejiang University has now investigated the impact of methanol–gasoline blends on the pollutant emissions of port-fuel injected spark ignition (SI) engines. A paper on their work is published in the ACS journal Energy & Fuels.

Solid-state LiDAR company Quanergy raises $90M in Series B; valuation passes $1B

23 August 2016

Quanergy Systems, Inc., a leading provider of solid-state LiDAR sensors and smart sensing solutions (earlier post), raised $90 million in Series B funding at a valuation well over $1 billion. Sensata Technologies, Delphi Automotive, Samsung Ventures, Motus Ventures and GP Capital participated in the round. This investment brings the company’s total funds raised to approximately $150 million.

Quanergy intends to use the investment and leverage its intellectual property to work with its partners in ramping up the production of its solid-state LiDAR sensors. These sensors use standard semiconductor manufacturing processes and have no moving parts on a macro scale or a micro scale, offering significantly lower cost, higher reliability, superior performance, increased capability, smaller size and lower weight when compared to traditional mechanical sensors, sometimes named hybrid solid state sensors.

PNNL-Lanzatech team hits milestone on waste-gas-to-ethanol-to-jet project

23 August 2016

With funding from Bioenergy Technologies Office (BETO), Pacific Northwest National Laboratory (PNNL) has been working with industry-partner LanzaTech to convert alcohols derived from captured carbon monoxide, a byproduct in the production of steel, into synthetic paraffinic kerosene, a non-fossil-based jet fuel. The technology not only provides a viable source of sustainable jet fuel but also reduces the amount of greenhouse gasses emitted into the atmosphere.

The team recently reached a significant milestone on the project, producing over five gallons of synthetic paraffinic kerosene in a lab environment. Five gallons is the quantity needed for “fit-for-purpose” testing.

BC government unveils climate plan

23 August 2016

The government of British Columbia recently unveiled its Climate Leadership Plan, targeting the reduction of net annual greenhouse gas emissions by up to 25 million tonnes below current forecasts by 2050 and the creation of up to 66,000 jobs over the next ten years. BC’s target is to reduce 2050 emissions 80% below 2007 levels.

The plan’s initial 21 action items include making electric vehicles more affordable and boosting the Low Carbon Fuel Standard from 10% to 15%. Government is also targeting making buildings more efficient, sequestration opportunities in forests and emission reductions in natural gas production and processing.
