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.

Lightning Hybrids secures order for 35 hydraulic hybrid systems from Kiessling Transit
March 05, 2015
Lightning Hybrids, developer and manufacturer of hydraulic hybrid systems for medium- and heavy-duty trucks and buses (earlier post), announced an agreement with Kiessling Transit to supply 35 hydraulic hybrid systems. The sale marks Lightning Hybrids’ largest order to date. The company’s system demonstrated improvements of 30% in fuel efficiency and significantly reduced NOx emissions during a year-long pilot program with the leading Massachusetts-based transportation company.
Kiessling Transit’s vehicles, featuring new 2015 and 2016 model year Ford E450 chassis and Elkhart Coach bodies, will have the Lightning Hybrids patented parallel hybrid system installed prior to delivery this summer. The technology, which has no electric batteries, applies a hydraulic system to the driveline of a vehicle to regenerate braking energy. Hydraulic pumps and a lightweight accumulator store braking energy and use the stored energy to power the wheels. The application of this technology will result in improved emissions, less fuel use, longer brake life, better low-end torque, and lower maintenance and operational costs.
UPS accelerates use of ORION routing optimization software; reducing 100M miles driven annually at full deployment
March 03, 2015
UPS expects its ORION (On-Road Integrated Optimization and Navigation) routing system (earlier post) to reduce the distance driven by its drivers by 100 million miles annually when fully implemented in 2016. The company is accelerating its implementation to complete all planned US routes by then. The deployment will result in a 100,000-metric-ton reduction in CO2 emissions, equivalent to taking 21,000 passenger cars off the road for a year, according to the Greenhouse Gas Equivalencies Calculator.
The company expects additional benefits including annual savings of 10 million gallons of fuel and more than $300 million when ORION completes US implementation. Additional environmental benefits and cost reduction savings will be realized when vehicles outside the US are equipped with the technology in future years, the company said. During 2015, UPS plans to complete installation of ORION routing on about 70% of the planned routes.

Through research work and studies, the two groups will develop pilot projects on new mobility solutions and continue to foster the sustainable mobility of the present and future, focusing on four main areas:
GKN to supply 500 electric flywheel hybrid drive systems to Go-Ahead Group for buses
July 29, 2014
UK transport operator Go-Ahead Group has ordered 500 electric flywheel Gyrodrive systems from GKN Hybrid Power for use in buses. The Gyrodrive Kinetic Energy Recovery System (KERS) system (featured in Audi’s LeMans-winning R18 e-tron quattro) harvests braking energy normally lost as heat.
When the driver brakes, a traction motor on one of the axles slows the vehicle, generating electricity at the same time. This electricity is used to charge the flywheel, spinning it at up to 36,000 rpm. When the driver accelerates, the system works in reverse. The energy is drawn from the flywheel and converted back into electricity to power the traction motor, which helps accelerate the bus back up to speed, generating fuel savings of more than 20% at a significantly lower cost and weight (60 kg, 132 lbs) than battery hybrid alternatives. Useable stored energy is 1.2MJ, with peak power of 120kW.
Study finds testing the technology the strongest initial motivation for fleet managers adopting EVs
July 25, 2014
According to a report from Frost and Sullivan (Kumar, 2013), fleet managers adopted more than half of EVs sold globally up to 2013. A new study of factors influencing fleet managers’ adoption of electric vehicles has found that testing new technologies was the strongest driver of initial EV adoption, followed by lowering environmental impacts; government grants; and improving the organization’s public image. Thereafter fleet managers adopted or indicated an intent to adopt a larger number of EVs because of the benefits that they offer.
The study by William Sierzchula at Delft University of Technology, published in the journal Transportation Research Part D, used fleet manager interviews and pilot project report to investigate 14 US and Dutch organizations that adopted EVs from 2010 to 2013 to determine which factors influenced their purchase decisions. In addition, Sierzchula also analyzed the reasons why these same firms did or did not expand their EV fleets.
EEI encourages utilities to spend at least 5% of fleet acquisition budgets on plug-ins
July 23, 2014
The Edison Electric Institute (EEI) released a white paper, “Transportation Electrification: Utility Fleets Leading the Charge,” that focuses on the electric power industry’s effort to accelerate the expansion of electric transportation in commercial and retail markets, beginning with electric utility fleets. The paper encourages investor-owned electric utilities to meet an industry-wide goal to spend at least 5% of annual fleet acquisition budgets on plug-in electric vehicles (PEVs) and technologies.
An analysis of utility fleets by Utilimarc shows only about 1.7% of the vehicles purchased by electric utilities in the last five years were equipped with plug-in technology.
ABB and Volvo Buses partnering on fast-charging system for hybrid and electric buses
July 22, 2014
ABB and Volvo Buses are partnering to co-develop and to commercialize electric and hybrid buses with open standards-based direct current (DC) fast charging systems. The cooperation will create a city-wide standardized charging system for electric and electric hybrid buses that can charge buses quickly through an automatic roof-top connection system at bus stops or through cabled charging systems overnight.
This approach, based on internationally accepted standards (EN61851-23), enables maximum re-use of existing e-mobility technologies, thereby ensuring a rapid deployment of urban e-mobility. The first joint project will be the implementation of Volvo Electric Hybrids and ABB’s automatic e-bus chargers in the Luxembourg public transport system, where as many as 12 Volvo Electric Hybrid buses operated by Sales-Lentz will be running on existing lines by 2015.
Virginia Tech wins $55M in federal contracts for commercial truck driver safety and automated vehicle research

Review: Chevrolet Silverado 2500HD with bi-fuel CNG option
July 14, 2014
|View of the CNG tank in the bed of a Silverado 2500HD with bi-fuel option. Click to enlarge.|
GM’s 2015 Chevy Silverado 2500HD with the bi-fuel (natural gas) option (earlier post) offers buyers—primarily commercial and fleet buyers—a strong natural-gas option in the ¾-ton pickup market that combines the excellent qualities of the base Silverado 2500HD with the economic (lower cost) and environmental (lower emissions of GHGs and criteria pollutants) benefits of natural gas fuel and packages the two together seamlessly.
As with any vehicle choice, there are trade-offs that need to be balanced against target use. In the case of the 2500HD bi-fuel, the two main trade-offs are a reduction in power and torque in CNG mode compared to gasoline mode, and the loss of a portion of the bed of the truck to the 3,600 psi CNG tank and its box-like enclosure. (It looks like a hefty black tool box mounted across the front of the bed.) Of those two trade-offs, only the second is permanent. The driver can easily switch from CNG to gasoline with the flick of a switch, essentially reverting the 2500HD to its conventional gasoline cousin, with the accompanying boost in power and torque for occasions that might call for it.
Report finds progress in UK Low Carbon Emissions Bus uptake, but a need to review incentives
July 06, 2014
Despite the recent uptake of low carbon emission buses (LCEBs) in the UK, significant barriers remain to sustained market growth, and there are risks of current progress being disrupted, according to a new report prepared for the UK LowCVP by Transport & Travel Research Ltd, in partnership with TRL.
LCEBs are defined as vehicles producing at least 30% fewer lifecycle greenhouse gas emissions than a current Euro-III-equivalent diesel bus of the same total passenger capacity. The well-to-wheel greenhouse gas emissions, expressed in grams of carbon dioxide equivalent measured over a standard test, take into account both the production of the fuel and its consumption.

Study finds V2G-capable electric school buses cost-effective with current technology; financial and environmental benefits
May 29, 2014
Electric school bus fleets with vehicle-to-grid (V2G) capabilities are cost-effective with today’s technology, and could save schools money while reducing greenhouse gas emissions and improving public health, according to a new study by a team at the University of Delaware’s College of Earth, Ocean, and Environment (CEOE).
Lance Noel and Regina McCormack conducted a cost-benefit analysis of owning and operating a V2G-capable electric school bus, and compared its cost-effectiveness to a traditional diesel school bus. They analyzed several factors, including fuel expense, electricity and battery costs, health externalities, and frequency regulation market price. The V2G-capable electric bus provides the school savings of $6,070 per seat in net present value ($230,000 per bus over the vehicle’s 14-year lifespan) and becomes a net present benefit after five years of operation. Without externalities (e.g., medical and climate change costs), the net present benefit would be $5,700 per seat.

Cambridge study of near-term alternative London bus technologies finds lean-burn CNG most costly with greater climate impact than diesel
May 01, 2014
Researchers from the University of Cambridge have conducted a comprehensive environmental cost–benefit analysis of near-term alternative bus technologies. The study considered emissions of non-methane hydrocarbons (NMHC), CO, NOx, PM2.5, sulfur dioxide (SO2), and ammonia (NH3), as well as the lifecycle climate impact of CO2 and non-CO2 greenhouse gases (GHG) on a CO2-equivalent basis.
Their findings indicated that emission control strategy retrofits are the least costly near-term intervention to reduce urban air pollution. Although hybrid buses provide net GHG reductions and air quality improvements, associated costs are higher and more uncertain than emission retrofits. Lean-burn (spark ignition) compressed natural gas (LB-CNG) delivers the lowest health impacts due to the significant reduction of PM2.5, but has relatively high associated CO2e emissions that negate the health benefits, they found. As a result, current LB-CNG vehicles are the most costly of all of the modeled technologies, they concluded. Their study appears in the ACS journal Environmental Science & Technology.
