Ames Lab team replaces Dysprosium in permanent magnets with Cerium for lower-cost, high performance solution

24 April 2015

Researchers led by a team at the US Department of Energy’s Ames Laboratory have created a new lower-cost magnetic alloy that is an alternative to conventional NdFeB-based permanent magnets. The new alloy—a potential replacement for high-performance permanent magnets found in EV motors and wind turbines—replaces dysprosium (Dy), one of the scarcest and costliest rare earth elements.

The new alloy of neodymium, iron and boron co-doped with cerium and cobalt is a less expensive material with properties that are competitive with traditional sintered magnets containing dysprosium. As reported in a paper in the journal Advanced Materials, the Ce, Co co-doped alloys have excellent high-temperature magnetic properties with an intrinsic coercivity being the highest known for T ≥ 453 K (180 ˚C).

Opinion: Oil Price War May Benefit both US Shale and Saudi Arabia

24 April 2015

by Michael McDonald on Oilprice.com

Even as financial commentators on CNBC are starting to come around to the idea of a bottom in oil prices, the key question for US oil producers remains one of timing. How long will the oil price slump last? Is this a relatively short term event like 2008, or a longer term slump like the one in the mid 1980’s?

After the oil price crash in 1985, it took almost twenty years for prices to revert to previous levels. If oil does not return to $100 a barrel until 2035, there will be a lot less shale companies around. Some market commentators have cited hedging as a potential source of safety for oil producers, but the truth is that given most firms’ individual levels of hedging and the price of oil today, the hedges are more of a Band-Aid over a gunshot wound than anything else.

GM provides technical details of the Gen 2 Voltec propulsion system used in the 2016 Volt

23 April 2015

The second-generation “Voltec” extended range electric powertrain applied in the MY2016 Chevy Volt (earlier post) marks a significant evolution in the electric drive technology platform from its first-generation origins. After proving a initial look at the design and capability of the different components (earlier post) late last year, GM is now providing deeper technical insight into the second-generation platform.

At the SAE 2015 World Congress in Detroit this week, GM engineers are presenting four papers on the technology of the Gen 2 Voltec propulsion system: an overview of the system and the realized improvements in efficiency and performance; a paper on the significantly re-engineered traction power inverter module (TPIM); a paper on the design and performance of the new electric motors used in the propulsion system; and a paper on the selection and design of the optimized gasoline-fueled 1.5-liter range extender engine.

LG Chem and Eguana partner on Li-ion residential energy storage system for North America

23 April 2015

Eguana Technologies, a supplier of power control and conversion solutions for distributed energy storage systems and Li-ion manufacturer LG Chem have combined their technologies under a multi-year agreement to deliver a certified, fully integrated energy storage system (ESS) Eguana calls “AC Battery”. The modular system is targeted as a residential product, but also has the potential to be aggregated for small commercial and industrial (C&I) end-users.

Basic product capacity is 6.4 kWh. Eguana designed the package around LG Chem’s battery modules and supplies its Bi-Direx inverter and controls subassembly. The low voltage design enables high-capacity batteries to operate in lower power ratings needed for decentralized systems (i.e. residential rooftop solar). Eguana has also worked with Germany-based Sonnenbatterie on a similar ESS solution.

DOE awards U-Mich team $1.2M to synthesize and characterize promising MOFs for high-density H2 storage

23 April 2015

The US Department of Energy (DOE) has awarded a multidisciplinary team at the University of Michigan $1.2 million to investigate further highly promising metal-organic frameworks (MOFs) that the team had identified earlier as more efficient materials for high-density on-board hydrogen storage for fuel cell vehicles. (Earlier post.)

The U-M team’s efforts to develop such materials began in 2012 with researchers from multiple disciplines: Mike Cafarella, assistant professor of computer science and engineering; Antek Wong-Foy, associate research scientist in chemistry; Don Siegel, assistant professor of mechanical engineering; and postdoctoral researcher Jacob Goldsmith.

NRC report recommends ways to overcome barriers hindering purchases of PEVs; vehicle cost, battery tech and consumer knowledge among others

22 April 2015

Vehicle cost, current battery technology, and inadequate consumer knowledge are some of the barriers preventing widespread adoption of plug-in electric vehicles, according to a new congressionally mandated report from the National Research Council. Developing less expensive, better performing batteries is essential to reducing overall vehicle cost, and a market strategy is needed to create awareness and overcome customer uncertainty, the report finds. The report recommends a range of incentives that the federal government can offer to address these and other barriers.

The premise of the report—“Overcoming Barriers to Deployment of Plug-in Electric Vehicles”—is that there is a benefit to the United States if a higher fraction of vehicle miles traveled is fueled by electricity rather than by petroleum due to the resulting reduction in dependence on petroleum and reduction in emissions of greenhouse gases and criteria pollutants. The task of the committee of experts and stakeholders writing the report was (1) to identify market barriers slowing the purchase of PEVs and hindering the deployment of supporting infrastructure in the United States and (2) to recommend ways to mitigate those barriers.

Lightning Hybrids (LH), a provider of hydraulic hybrid drive systems for fleet vehicles such as shuttle buses, delivery vehicles and work trucks (earlier post), has released some results from its ongoing emissions testing with SGS Environmental Testing Corporation. Broadly, the test results show significant reductions in NOx, particularly against a non-hybrid diesel baseline, and fuel economy improvements of up to 18% for the vehicle and under the drive cycles tested.

By design, LH noted, a hybrid drive system provides benefits during a vehicle’s braking and subsequent acceleration phases, so not all drive cycles will take equal advantage of the system. For example, an urban delivery truck which stops many times per mile will benefit strongly, whereas a truck that spends most of its time on the highway would not be a good candidate for any form of hybridization.
