April 15, 2014
|The infrared photo shows a temperature increase of only 9.8 degrees at the junction between the pantograph and the overhead charging rail of the Opbrid Bůsbaar at 625 A. Click to enlarge.|
During recent tests of Hybricon Bus Systems’ new Arctic Whisper (HAW) urban bus in Umeå, Sweden (earlier post), the Opbrid Bůsbaar achieved ultrafast charging at 625 amps for 6 minutes. This paves the way for charging at 500 – 1000 kW or more to achieve 2- to 3-minute charges at the end stations of longer bus routes. It also allows all-electric heating and 5 – 6 minute charging for the upcoming 18 m 4WD Arctic Whisper articulated bus.
The Opbrid Bůsbaar is an overhead, pantograph-based fast-charging station for buses. In the future, this technology may enable other applications such as medium-distance electric buses or even long distance buses and trucks, the company said.
NRC report offers guidance on development of Phase 2 rules to reduce fuel consumption and GHG from medium-and heavy-duty vehicles; more natural gas and aerodyanamics, expanded lifecycle considerations
April 03, 2014
Expanding the use of natural gas as a transportation fuel and greater use of aerodynamic devices on trailers are among the 17 overarching strategies recommended by a new National Research Council report for reducing fuel consumption by tractor-trailers, transit buses, commercial vehicles, trucks, and other medium- and heavy-duty vehicles (MHDVs).
The report follows a 2010 Research Council report the findings and recommendations of which informed the “Phase I Rule” on fuel consumption and greenhouse gas emissions of medium- and heavy-duty vehicles issued jointly by the National Highway Traffic Safety Administration and US Environmental Protection Agency. (Earlier post.) The new report offers guidance for the “Phase II Rule” under development, which is directed at technologies and programs in the post-2018 time frame. (Earlier post.) The committee will expand upon this new work and issue a final report in 2016 that will cover a broader range of technologies and approaches that address the 2025-2030 time frame.

EIA: light duty vehicle energy consumption to drop 25% by 2040; increased oil production, vehicle efficiency reduce US oil and liquid imports
December 16, 2013
Reflecting slow growth in travel and accelerated vehicle efficiency improvements, US light-duty vehicle (LDV, cars and light trucks) energy use will decline sharply between 2012 and 2040, according to the US Energy Information Administration’s (EIA’s) Annual Energy Outlook 2014 (AEO2014) Reference case released today.
AEO2014 includes a new, detailed demographic profile of driving behavior by age and gender as well as new lower population growth rates based on updated Census projections. As a result, annual increases in vehicle miles traveled (VMT) in LDVs average 0.9% from 2012 to 2040, compared to 1.2% per year over the same period in AEO2013. The rising fuel economy of LDVs more than offsets the modest growth in VMT, resulting in a 25% decline in LDV energy consumption decline between 2012 and 2040 in the AEO2014 Reference case.

Ricardo report finds hybrid buses have higher regulated emission intensities than conventional buses; need for whole vehicle testing
December 09, 2013
While technologies for low carbon buses such as hybridization offer the prospect of significant reductions in fuel consumption and CO2 emissions compared to conventionally powered vehicles, the improvement in terms of regulated emissions (criteria pollutants) may not be as great, according to a new report by Ricardo. Local emissions from buses are of particular significance, as the vehicles mainly operate in urban areas.
The UK’s Low Carbon Vehicle Partnership (LowCVP) commissioned the review of the air quality impacts arising from the recent rapid increase in the number of low carbon buses in the UK, a result of subsidies provided through the Government’s Green Bus Funds. The UK now has around 1,300 low carbon buses in operation. The new report recommends that the legislation needs to consider hybrid technology impacts in the test processes to avoid potential unintended consequences in terms of local emissions.

New valveless electro-hydraulic steering system for off-road equipment shows significant fuel savings and productivity benefits
September 25, 2013
Researchers at Purdue University have developed a new valveless hydraulic steering system for heaving construction equipment that improves efficiency and reduces fuel consumption. The new approach eliminates valves now needed to direct the flow of hydraulic fluid in steering systems and uses advanced algorithms and models to control hydraulic pumps precisely. New designs might also incorporate textured “micro-structured” surfaces inside pumps to improve performance.
Testing the new “electro-hydraulic power steering system” on a front loader has shown a 15% fuel savings and 23% increased machine productivity, for a total fuel efficiency increase of 43% during steering maneuvers. The findings are detailed in a research paper being presented during the SAE 2013 Commercial Vehicle Engineering Congress (1-3 October). The paper was authored by doctoral student Naseem Daher and Monika Ivantysynova, Maha Fluid Power Systems Professor in Purdue’s School of Mechanical Engineering, and director of Purdue’s Maha Fluid Power Research Center.

Ricardo is advancing its work with two novel technologies to improve the efficiency of heavy-duty goods vehicles: a cryogenic split-cycle engine “CryoPower” (earlier post), and a low-carbon waste-heat powered microwave fuel reformer “HeatWave II”.
Heavy duty vehicles, such as long haul trucks, represent a significant challenge in terms of the reduction of carbon dioxide emissions. An essential element of the transportation mix of modern industrialized society, they are inherently less amenable to the type of electrification and hybridization strategies that are already contributing to reduced carbon emissions and potential long-term sustainability for the light vehicle sector.

|BRUSA 750V electric drive components. Click to enlarge.|
BRUSA Elektronik AG is now offering its proven electric-drive components—including motor, controller, power electronics, battery pack and chargers—in 750-volt versions. The new 750-volt products are suited for use in commercial vehicles and applications demanding very high output performance.
Increasing the voltage reduces the current with the performance remaining the same. Lower current leads to a reduction of cable thicknesses and bending radii. This will directly result in weight and material savings—especially with commercial vehicles of a certain length such as trucks or buses, BRUSA says.
ARB researchers evaluate in-use heavy-duty NOx aftertreatment systems, find elevated levels during certain lower-temperature operations
July 09, 2013
A team from the California Air Resources Board (ARB) reports on their evaluation of the in-use emissions performance of four different heavy-duty diesel engines certified to the MY 2010 or interim MY 2010 NOx standards over a wide range of driving conditions in California in a paper published in the ACS journal Environmental Science & Technology.
One of the trucks was equipped with exhaust gas recirculation (EGR); three were equipped with EGR and a selective catalytic reduction (SCR) device. The results indicated that brake-specific NOx emissions for the truck equipped only with an EGR were independent of the driving conditions—and exceeded the certification value over each segment of the entire test route. Results also showed that for typical highway driving conditions, the SCR technology is proving to be effective in controlling NOx emissions. However, they also found that under operations where the SCR systems do not reach minimum operating temperature—e.g., cold starts and some low-load/slow-speed driving conditions—NOx emissions are still elevated.

A wide range of technologies can cut carbon emissions from buses and provide a short-term payback at current fuel prices and subsidy levels, according to a new report prepared for the UK’s Low Carbon Vehicle Partnership (LowCVP) by Ricardo. Overall, the study indicates that significant improvements in bus CO2 can be achieved in the medium to long term through development, incentivization (or regulation) and implementation of new vehicle technologies and fuels.
The aim of the LowCVP study was to identify a range of low carbon fuels and technologies which can cost-effectively reduce well-to-wheel (WTW) CO2 emissions for urban buses in the UK. The report developed technology roadmaps to illustrate when these technologies are likely to be ready for deployment into the bus market, focusing on the timescales 2012-2020 and 2020-2050. The study also examined the wider role of the selected fuels and technologies for decarbonizing heavy goods vehicles.

Obama climate plan calls for new fuel economy standards for heavy-duty vehicles post-2018; cleaner fuels and investment in advanced fossil energy
June 25, 2013
Among the transportation-related elements of US President Barack Obama’s new climate action plan, which he is outlining today in a speech at Georgetown University, is the development of new fuel economy standards for heavy-duty vehicles post-2018. In 2011, the Obama Administration finalized the first fuel economy standards for Model Year 2014-2018 for medium- and heavy-duty trucks, buses, and vans. (Earlier post.)
The plan as outlined also calls for further work on advanced biofuels, advanced batteries and fuel cell technologies in every transportation mode. In coming months, the plan notes, the Department of Transportation will work with other agencies to further explore strategies for integrating alternative fuel vessels into the US flag fleet.
SoCalGas, California agencies funding $9M RFP to develop ultra-low NOx heavy-duty natural gas engines
June 13, 2013
Southern California Gas Co. (SoCalGas), the South Coast Air Quality Management District (SCAQMD), the San Joaquin Valley Air Pollution Control District (SJVAPCD) and the California Energy Commission (CEC) are jointly funding a request for proposals (RFP) (P2013-22) issued by SCAQMD to support the development of ultra-clean natural gas engines for a variety of heavy-duty vehicle applications in the South Coast Air Basin (SCAB) and San Joaquin Valley Air Basin (SJVAB).
The initiative, funded up to $9 million by the participating agencies together with $500,000 in matching funds from SoCalGas, aims to demonstrate natural gas engines capable of achieving aggressive, near-zero emission standards for on-road, heavy-duty vehicle applications suitable for refuse, goods movement, drayage, transit, or school bus applications.
Volvo Trucks to begin limited production of DME heavy-duty trucks in NA in 2015; customer trials; Oberon partnership
June 07, 2013
|Volvo VNL D13 with DME. Click to enlarge.|
At an event in Sacramento, California, Volvo Trucks announced that it will commercialize dimethyl ether (DME)-powered heavy-duty commercial vehicles in North America, with limited production beginning in 2015. Volvo also revealed ongoing customer field testing of DME trucks in the US (with Safeway and Martin Transportation), as well as its partnership in the customer trials with startup DME producer Oberon Fuels. Oberon Fuels is the first company to announce plans to commercialize DME fuel production in North America. (Earlier post.)
DME offers diesel-quality performance with a high cetane number and low auto-ignition temperature, but burns cleanly without producing any soot. It is non-toxic, non-carcinogenic, and can be made from a variety of sustainable domestic sources, as well as from North America’s abundant supply of natural gas. The carbon intensity of the DME will vary with the feedstock, but with the use of bio-gas (biomethane) from an anaerobic digester as input into the Oberon process, DME can provide up to a 95% CO2 reduction compared to diesel. Volvo has been testing Bio-DME in Sweden since 2009. (Earlier post.)

ABB has developed and is demonstrating a high-capacity “flash charging” system for electric buses. The system enables onboard batteries to be charged in 15 seconds with a 400 kW boost at selected stops using a roof-mounted system (“Flash station”). The flash stations are connected to the 50kVA electricity network and also have a 3kWh storage unit (supercap) for smoothing peaks in consumption.
At the end of the bus line (“Terminus station”) a 3 to 4 minute boost at 200 kW tops up the batteries. At the depot station, the bus plugs into a multi-bus supply station connected to the 50 kVA network.
CALSTART to evaluate Navitas Systems’ military-grade Li-ion 6T batteries in Class 8 highway trucks
May 22, 2013
Navitas Systems LLC, which earlier this year acquired substantially all of the assets of bankrupt A123 Systems’ former Ann Arbor, Michigan-based government business, including US military contracts, has signed a contract to supply prototypes of its upcoming 6T lithium-ion battery (earlier post) for use by CALSTART in assessing the efficacy of this advanced battery in hot and cold weather testing on Class 8 highway trucks.
The 6T battery is commonly used in military vehicles, and to-date has been based on lead-acid chemistry. The Navitas 6T prototype batteries embody the same physical form factor, but utilize advanced lithium iron phosphate chemistry, offering greater cycle and calendar life, discharge runtime, charge acceptance rate and amp-hour throughput over life, all at half the weight of lead acid.
