President Obama announces two new public-private manufacturing innovation institutes; new manufacturing innovation institute competition
February 25, 2014
President Obama announced two new manufacturing innovation institutes led by the Department of Defense supported by a $140-million Federal commitment combined with more than $140 million in non-federal resources: (1) a Detroit-area-headquartered consortium of businesses and universities, with a focus on lightweight and modern metals manufacturing; and (2) a Chicago-headquartered consortium of businesses and universities that will concentrate on digital manufacturing and design technologies.
Obama also launched a competition for a new manufacturing innovation institute to build US strength in manufacturing advanced composites, the first of four new competitions to be launched this year.
DOE to award up to $12M for technologies to produce renewable carbon fiber from biomass
February 04, 2014
The US Department of Energy (DOE) will award (DE-FOA-0000996) up to $12 million in funding to advance the development of a cost-competitive pathway to produce high-performance carbon fiber for vehicle lightweighting from renewable non-food biomass. Reducing a vehicle’s weight by just 10% can improve fuel economy by 6% to 8%.
Carbon fiber composites are lightweight, yet strong, materials that can greatly improve vehicle fuel efficiency when incorporated into structural and non-structural components. Carbon fibers are polymers that are typically made from petroleum and natural gas feedstocks (propylene and ammonia, respectively) that react to form acrylonitrile (ACN) which is then polymerized and spun into polyacrylonitrile (PAN).
New ceramic hollow fiber substrate for catalytic converters cuts fuel consumption, size and manufacturing costs
January 28, 2014
A new ceramic hollow fiber substrate for catalytic converters designed by Dr. Benjamin Kingsbury and colleagues at Imperial College London could cut the size and precious metal loading of the devices in automobiles while reducing fuel consumption and and manufacturing costs. Kingsbury has founded MicroTech Ceramics Ltd. as a spin-out to commercialize the technology.
The new structure can achieve a 2-3% fuel saving in engines (through the elimination of backpressure), or offer high performance cars an equivalent increase in engine power. It also enables the size of catalytic convertors to be reduced by around 50%, offering engine and exhaust system designers greater freedom. The new substrate can use up to 80% less rare metal, a development that could significantly reduce costs for vehicle manufacturers.
Constellium and UACJ plan JV in US to produce Body-in-White aluminium sheet for the automotive industry
January 24, 2014
Constellium N.V, a global aluminum products company formerly known as Alcan Engineered Products and headquartered in Amsterdam, and UACJ Corporation (UACJ), a Japan-based global aluminum manufacturer, are joining forces with a view to supply and market aluminum Body-in-White sheet to the North American automotive industry. To achieve this goal, Constellium and UACJ, through Tri-Arrows Aluminum Inc. (TAA), (UACJ’s subsidiary with Sumitomo Corporation and Itochu Group), intend to create a joint venture company in the United States, as an equal partnership, to serve the North American market.
The JV is expected to include a continuous heat treatment and conversion line with an initial target capacity of 100,000 metric tons supplied by cold rolled coils from both partners’ rolling mills. The planned facility is designed to allow for expansion beyond 100,000 tons. The total joint investment by both parties is expected to amount to approximately $150 million.

The US Department of Energy (DOE) will award $49.4 million to projects to to accelerate research and development of new vehicle technologies. The new program-wide funding opportunity (DE-FOA-0000991) (earlier post), was announced by Energy Secretary Ernest Moniz at the Washington Auto Show.
The funding opportunity will contains a total of 13 areas of interest in the general areas of advanced light-weighting; advanced battery development; power electronics; advanced heating, ventilation, air conditioning systems; advanced powertrains (including the ability to meet proposed EPA Tier 3 tailpipe emissions standards); and fuels and lubricants. These areas of interest apply to light, medium and heavy duty on-road vehicles.
DOE issues $10M incubator FOA for batteries, power electronics, engines, materials, fuels and lubricants
January 18, 2014
The US Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy’s (EERE’s) Vehicle Technologies Office (VTO) issued an Incubator Funding Opportunity Announcement (FOAs) for a total of approximately $10 million. (DE-FOA-0000988)
EERE is focused on achieving well‐defined mid‐to‐long term clean energy goals for the US, and in that context has established multi‐year plans and roadmaps, with a concomitant focus of the majority of its resources on a limited number of “highest probability of success” pathways/approaches to ensure that the program initiatives are supported at a critical mass (both in terms of dollars and time) for maximum impact. While this roadmap‐based approach can be a strength, it can also create challenges in recognizing and exploring unanticipated, game changing pathways/approaches which may ultimately be superior to the pathways/approaches on the existing roadmaps.

A newly-released report by the Center for Automotive Research (CAR) concludes that the automotive industry is not only “high-tech,” it is frequently a leader in technological developments and applications. The report, supported by the Alliance of Automobile Manufacturers, measures the technological nature of today’s auto industry and compares it to other sectors of the economy often viewed as technologically advanced.
The report authors acknowledge the difficulty of defining “high-tech” in an ever-changing economic environment. After reviewing of the works of several researchers and government agencies, CAR developed a working definition to differentiate high-tech industries from other sectors. Broadly, high-tech industries generally have the following characteristics:
Computational first-principles approach identifies dozens of new platinum-group alloys
January 07, 2014
Researchers from Duke University, Brigham Young University, and Carnegie Mellon University have used high-throughput first-principles calculations to identify dozens of platinum-group alloys (binary systems of the platinum-group metals—PGMs—with the transition metals) that were previously unknown but that could prove beneficial in a wide range of applications.
The platinum-group metals (PGMs)—osmium, iridium, ruthenium, rhodium, platinum, and palladium—play essential roles in a wide variety of industrial applications. The primary application of PGMs is in catalysis, where they are core ingredients in the chemical, petroleum, and automotive industries. Although are essential, they are also very costly.

A three-year collaboration between Lincoln, Weyerhaeuser and auto parts supplier Johnson Controls has resulted in the creation of a tree-based, renewable alternative to fiberglass for use in auto parts. (Earlier post.) The 2014 Lincoln MKX features the use of Cellulose Reinforced Polypropylene (called “THRIVE” composites by Weyerhaeuser) in the floor console armrest substrate—a structural piece located within the center console armrest.
Pieces made from CRP are roughly 6% lighter, and decrease the reliance on less-environmentally friendly fiberglass parts. The use of Cellulose Reinforced Polypropylene in the MKX, while relatively small, marks an advancement that has the potential to play a more impactful role in the future, suggested Dr. Ellen Lee, plastics research technical expert for Ford Motor Company. Ford engineers are using the company’s development and deployment of soy-based foam as an model—i.e., starting out small, then improving the material and widening the application.
DOE to issue FY14 Vehicle Technologies program-wide funding opportunity announcement
The Department Of Energy (DOE), Office of Energy Efficiency and Renewable Energy (EERE) intends to issue, on behalf of its Vehicle Technology Office (VTO), a program-wide Funding Opportunity Announcement (DE-FOA-0000991) for fiscal year 2014 on or about January 2014. The advance notice (DE-FOA-0001053) is to alert interested parties of the coming FOA.
The areas of interest outlined in the notice of intent (NOI) fall into two broad categories: technologies to advance plug-in electric vehicles; and technologies to improve fuel efficiency, including dual-fuel, fuel properties (e.g., high octane fuels), and advanced powertrain work.
EnerG2 develops new carbon adsorbent material for on-board natural gas storage
December 18, 2013
EnerG2, a manufacturer of advanced carbon materials for next-generation energy storage (generally for batteries and ultracapacitors), has leveraged its polymer chemistry technologies to develop materials for adsorbed natural gas (ANG) applications. The ultra-high surface area carbon adsorbent material, which packs at optimal density and has been produced at scale, is compatible with any and all tank geometries and systems, the company says.
Currently, natural gas vehicles are fitted with on-board fuel tanks that are too large, cumbersome, and expensive to properly facilitate the widespread adoption of natural gas vehicles in the US and globally. Additionally, the low volumetric density of natural gas (~30% less energy by volume than gasoline) limits range, and makes cost-effective storage solutions a significant challenge. One possible solution is adsorbed storage; the interest is so keen, that ARPA-E awarded a combined $10.875 million in 2012 to four different projects (led by Ford, GTI, Texas A&M and SRI) to develop new sorbent materials for on-board natural gas storage. (Earlier post.)

December 06, 2013
|Twist beam assembly mass comparison. Click to enlarge.|
Results of a new design study for a lightweight steel proof-of-concept twist beam (used in suspensions) by the Steel Market Development Institute’s (SMDI) Automotive Applications Council indicate that the preferred U-Beam Design based on 22MnB5 tubular construction with DP780 and SPFH540 sheet achieves a 30.0% mass reduction relative to the baseline assembly, at a 12–15% premium in manufacturing cost at production volumes of 30,000 to 250,000 vehicles per year, respectively.
An S-Beam Design based on 22MnB5 sheet, DP780 tube and HSLA550 materials was predicted to have a 14.9% mass reduction relative to the baseline assembly. The objective of the study was to develop a twist beam design achieving a 15–25% mass reduction with equivalent structural and elasto-kinematic performance relative to the baseline design at a ≤ 10% cost premium.
New simple aluminum-based hydride for hydrogen storage
November 11, 2013
Japanese researchers report the development of a simple-structured, aluminum-based interstitial hydride for hydrogen storage in a paper in the AIP Publishing journal APL Materials. Their compound, Al2CuHx, was synthesized by hydrogenating Al2Cu at an extreme pressure of 10 gigapascals (1.5 million pounds per square inch) and a high temperature of 800 °C (1,500 °F).
Lightweight interstitial hydrides with high hydrogen content—such as Mg-based hydrides, alanates, borohydrides, and amino boranes—have been proposed as a safe and efficient means for storing hydrogen for fuel cell vehicles, but so far, none have proven practical as a hydrogen repository.
JRC study finds 8 metals for low-carbon energy technologies at risk of shortages; EVs, wind and solar, and lighting the applications of most concern
November 04, 2013
A new European Joint Research Centre (JRC) study looking into the supply of raw materials for the manufacture of low-carbon energy technologies found that eight metals were at high risk of shortages. The applications, i.e. technologies, of particular concern as a result are electric vehicles, wind and solar energy, and lighting. The risk arises from EU dependency on imports, growing demand worldwide and geopolitical reasons.
The study builds on a 2011 effort which looked into the six key applications of the Strategic Energy Technology (SET) Plan: wind, solar, nuclear fission, bioenergy, carbon capture and storage (CCS) and the electricity grid. In the new study, these were re-assessed and considered along with 11 other technologies—including fuel cells, electricity storage, electric vehicles and lighting—treated in the new report, this time evaluated on the expected supplies of the metals and not on the current situation as in the first report.
Canada awards $30M to 10 automotive R&D projects; from electrified powertrains to hot stamping
October 28, 2013
The Government of Canada has awarded C$30 million (US$29 million) through the Automotive Partnership Canada (APC) initiative to 10 university-industry partnerships to advance innovative automotive technologies. With a total project value of more than C$52 million (US$50 million), the funding includes some $22 million from industry and other partners.
The largest award from APC is $8,928,200 to the McMaster University-Chrysler partnership (earlier post) for the development of next generation electrified powertrains. (Earlier post.) However, the selected projects include a range of technologies from hot stamping of parts to hydrogen fuel cell stacks.
Volvo Car Group testing lightweight structural energy storage material applied in trunk lid and plenum cover
October 17, 2013
Volvo Car Group—the only automaker participating in a 3.5-year EU-funded project developing a prototype material which can store and discharge electrical energy and which is also strong and lightweight enough to be used for car parts (earlier post)—has created two components for the testing and further development of the technology. These are a trunk lid and a plenum cover, tested within the Volvo S80.
The material combines carbon fibers and a polymer resin, creating a very advanced nanomaterial, and structural supercapacitors. The material can be moulded and formed to fit around the car’s frame in locations such as the door panels, the trunk lid and wheel bowl, substantially saving on space.

A new composite material created at Rice University is nearly impervious to gas and may lead to lighter and more efficient storage of compressed natural gas for vehicles. By adding modified, single-atom-thick hexadecyl-functionalized low-defect graphene nanoribbons (HD-GNRs) to thermoplastic polyurethane (TPU), the Rice lab of chemist James Tour made the resulting material far more impermeable to pressurized gas and far lighter than the metal in tanks now used to contain the gas.
In an open access paper in the journal ACS Nano, Tour and his colleagues at Rice and in Hungary, Slovenia and India reported that nitrogen gas effective diffusivity of the TPU was decreased by three orders of magnitude with only 0.5 wt% GNRs.

August 10, 2013
|Cycle performances of MIONCs, RAIONs, and CBIOs at a current density of 0.1 A g−1. Credit: ACS, Lee et al. Click to enlarge.|
A team in South Korea has developed a bottom-up self-assembly approach for the preparation of mesoporous iron oxide (Fe3O4) nanoparticle clusters (MIONCs) for use as an anode material in Li-ion batteries. The unique structure endowed the MIONCs with enhanced capacity retention, rate capability, and Coulombic efficiency, the researchers reported in a paper published in the ACS journal Nano Letters.
More importantly, they noted, the work showed that changing the geometric configuration of the material can result in stable battery performance through the confinement of SEI (solid−electrolyte interphase) layer formation. They suggested that their strategy can be considered a model framework and applied to other metal oxide nanoparticles (NPs) such as Co3O4 and NiO with high specific capacities. These findings further confirm that bottom-up self-assembly of active materials can improve battery performance, they concluded.
BMW Group presents prototype of i8 plug-in hybrid; first use of new 3-cylinder engine
August 07, 2013
|Prototype BMW i8 at the track. Click to enlarge.|
BMW i presented a prototype of its second production vehicle, the i8 (earlier post), at a driving event at the BMW Group’s Miramas test track in France. Following the world debut of the first production model, the battery-electric urban-focused BMW i3 (earlier post), the BMW Group’s next step will be to address the sports car segment with the plug-in hybrid BMW i8. The BMW i8 will make its world debut at the Frankfurt Motor Show next month and arrive in BMW showrooms in 2014.
Calculated using the EU test cycle for plug-in hybrid vehicles, the average fuel efficiency of the BMW i8 at model launch will be less than 2.5 liters/100 km, which equates to approximately 95 miles per US gallon, with CO2 emissions of less than 59 grams per kilometer.
EDAG study finds NanoSteel sheet steels can achieve up to 30% weight reduction in automotive structures
August 05, 2013
|NanoSteel body-in-white using the three grades of steel. Click to enlarge.|
The NanoSteel Company released the results of an automotive light-weighting study it had commissioned from EDAG, Inc., an independent engineering firm, demonstrating the potential for the company’s Advanced High Strength Steel (AHSS) (earlier post) to enable a 30% reduction of weight in the BIW (body-in-white) structure of a baseline mass-market sedan.
EDAG used methodology in the study consistent with recent similar studies, including NHTSA’s “Light Weight Vehicle (LWV)” study in 2012, and WorldAutoSteel’s “Future Steel Vehicle” design in 2011. The NHTSA LWV study was a comprehensive redesign of the 2011 Honda Accord that met North American competitive targets for safety and other significant vehicle attributes while optimizing for weight savings. EDAG duplicated the criteria and methods used then have been duplicated in that study to investigate NanoSteel’s materials.
New high-temperature ceramic capacitor could reduce cooling needs in power electronics for hybrids and EVs
August 02, 2013
Scientists from the National Physical Laboratory (NPL) in the UK have developed a new lead-free, high-temperature ceramic capacitor that could improve the efficiency and reliability of electric and hybrid vehicles.
Hybrid and electric vehicles rely on high efficiency power conversion and management, with automotive power electronics representing an emerging £40-billion (US$61-billion) global market, NPL noted. The power electronics found in vehicles today require cooling because of limitations in the temperature rating of components such as capacitors, which are used to store electrical energy. This is a disadvantage as the extra cooling systems add weight to the vehicles, reducing efficiency and reliability.
BYU friction bit joining process bonds aluminum to cast iron
July 15, 2013
Engineers at Brigham Young University (BYU) in Utah and the University of Ulsan in South Korea have used friction bit joining (FBJ) to bond dissimilar combinations of aluminum alloy A356 and grey cast iron.
The process of friction bit joining uses a small, consumable bit to create a solid-state joint between metals. The method was invented by BYU manufacturing engineering technology professor Michael Miles and retired BYU professor Kent Kohkonen, in their collaboration with local Orem-based company MegaStir Technologies, a joint venture between Schlumberger and Advanced Metal Products. MegaStir provides both low- and high-temperature friction stir welding (FSW) systems.

Backed by 27 companies in the sector, including supply chain companies, the commitment is expected to secure at least 30,000 jobs currently linked to producing engines and create many more in the supply chain.
The investment forms part of the report “Driving success – an industrial strategy for growth and sustainability in the UK automotive sector”, published jointly by the government and industry. It follows the recent plans for construction, aerospace and other key sectors to secure sustainable future growth in the economy.
Renault makes public its lifecycle study of Fluence ICE vs Fluence EV
July 11, 2013
|Renault’s comparison of the carbon footprint of EV and ICE vehicles over production, operation and end of life. The EV footprint (Fluence Z.E.) is shown with both UK and French grid mixes. Click to enlarge.|
Renault recently made public the findings of an internal study, published first in October 2011, detailing and comparing the lifecycle assessments (LCAs) of the battery-electric and two internal combustion engined versions (gasoline and diesel) of the Renault Fluence. The study used the series production versions launched in 2011, with the assumption of operation for 150,000 km (93,205 miles). (Since the BEV version has a shorter range, Renault noted, the way in which the miles are accumulated could differ from that of the ICE vehicles.)
The publication gives the opportunity for an “apples-to-apples” comparison between the environmental impacts of the two types of powertrains: same manufacturer, same model, same boundary conditions. Nevertheless, Renault noted, the study is contrasting a new technology (EVs) with a well-developed one; “environmental progresses are expected in a short term thank to key process improvement and massification of the production.”
Ford advancing rapid freeform sheet metal forming technology; CAD-driven tool may reduce costs and delivery time for parts

White House announces new commitments in support of Materials Genome Initiative
June 24, 2013
The Obama Administration and academic and industry partners announced a series of commitments in support of the Materials Genome Initiative (MGI, earlier post), a public-private endeavor that aims to cut in half the time it takes to develop novel materials that can fuel advanced manufacturing.
The MGI, overseen by the White House Office of Science and Technology Policy, helps to coordinate Federal materials science research across multiple agencies and encourages private-sector and academic researchers to develop and share basic materials science discovery data to speed innovation—much as geneticists accelerated the Human Genome Project by openly sharing basic DNA sequence data. Newly announced commitments are:

While reducing vehicle weight (lightweighting) by replacing steel and iron with alternatives such as aluminum, magnesium, and composites decreases fuel consumption and greenhouse gas emissions during vehicle use, it can increase energy consumption and GHG emissions during vehicle production.
Hyung Chul Kim and Timothy J. Wallington at Ford Motor’s Systems Analytics and Environmental Sciences Department set out to clarify the lifecycle benefits of vehicle lightweighting in a meta-analysis of previously published life cycle assessments (LCAs). While numerous studies assay the benefits of lightweighting, the wide variety of assumptions used makes it difficult to compare results from the studies, the pair noted in their paper, published in the ACS journal Environmental Science & Technology.
New MOF could enable more efficient and cost-effective production of high octane gasoline
May 24, 2013
An international team of researchers has developed a new metal-organic framework (MOF) that might provide a significantly improved method for separating hexane isomers in gasoline according to their degree of branching. A paper on the work is published in the journal Science.
Created in the laboratory of Jeffrey Long, professor of chemistry at the University of California, Berkeley, the MOF features triangular channels that selectively trap only the lower-octane hexane isomers based on their shape, separating them easily from the higher-octane molecules in a way that could prove far less expensive than the industry’s current method for producing high-octane fuel. The Long laboratory and UC Berkeley have applied for a patent on the MOF Fe2(bdp)3. (BDP2– = 1,4-benzenedipyrazolate)

Researchers at MIT have demonstrated two approaches for producing carbon fibers coated in carbon nanotubes without degrading the underlying fiber’s strength. A paper on the work, which could result in carbon-fiber composites that are not only stronger but also more electrically conductive, is published in the journal ACS Applied Materials & Interfaces.
Hierarchical carbon fibers (CFs) sheathed with radial arrays of carbon nanotubes (CNTs) are promising candidates for improving the intra- and interlaminar properties of advanced fiber-reinforced composites (such as graphite/epoxy) and for high-surface-area electrodes for battery and supercapacitor architectures, the authors note.

A new study by EDAG Group, commissioned by the Aluminum in Transportation Group of the US Aluminum Association, finds that an all-aluminum body in white (BIW) can deliver potential mass savings in the 35 – 40% range over a base steel BIW. This, when combined with secondary mass savings and other design changes, could boost fuel economy by around 18%.
The study built upon research EDAG performed last year for the US Environmental Protection Agency (EPA) examining mass reduction, safety and cost variables in a mid-size crossover Toyota Venza. The EPA study aimed to reduce vehicle mass by 20% while meeting all NHTSA and IIHS safety standards, and maintaining or improving performance, handling and braking.

Researchers from North Carolina State University have developed a new technique for creating ultra-strong magnesium alloys that maintain good ductility. By introducing stacking faults with nanoscale spacing into a magnesium alloy using conventional hot rolling, they produced a yield strength of 575 MPa, an ultimate strength of 600 MPa, and moderate ductility (uniform elongation of 5.2%).
The nano-spaced stacking faults are essentially a series of parallel fault-lines in the crystalline structure of the alloy that isolate any defects in that structure. The process can lead to Mg alloys with superior mechanical properties with potential structural applications in the automobile and aerospace industries, the researchers suggested in an open access paper in the journal Materials Research Letters.

Nissan Motor Co., Ltd. plans to expand the use of Advanced High Tensile Strength Steel (AHSS) into up to 25% of the vehicle parts (measured by weight) installed in its new production models starting in 2017 as one of its initiatives to help reduce vehicle weight.
Nissan, in collaboration with Nippon Steel Corporation and Kobe Steel, Ltd., earlier developed 1.2 gigapascal (GPa) Ultra High Tensile Strength Steel with High Formability. (Earlier post.) Prior to the development of 1.2GPa ultra high strength steel it had been difficult to use high tensile steels for vehicle parts with highly-complex shapes. This steel is first employed in the new Infiniti Q50, which goes on sale in North America in 2013.
