Alexander Dennis Limited (ADL), Britain’s biggest bus and coach manufacturer, has chosen GKN Hybrid Power as a preferred partner and committed to the purchase of 250 of its Gyrodrive electric flywheel hybrid systems (earlier post). ADL will focus initially on the introduction of the low emission technology to bus fleets in London and Oxford but anticipates rapid deployment across the UK in the next few years. It will also be working closely with GKN to develop the technology for international markets.

Instead of a battery, the Gyrodrive system uses a magnetically loaded high-speed carbon-fiber flywheel to store the energy generated by a bus as it slows down to stop. It then utilizes the stored energy to power a GKN EVO electric motor which helps accelerate the bus back up to speed, generating significant fuel savings of up to around 25% at a considerably lower cost than battery-hybrid alternatives.

UC Riverside researchers find mixed emissions impact from use of higher ethanol and butanol fuels in FFVs

24 November 2014

A study by University of California, Riverside researchers found that the use of higher ethanol blends and a 55% butanol blend in port-fueled and direct injection flexible fuel vehicles (FFVs) could lead to emission changes of GHGs, CO, aldehydes, BTEX (monoaromatic hydrocarbons of benzene, ethylbenzene, toluene, m/p-xylene, and o-xylene), and particulates.

In a paper in the ACS journal Environmental Science & Technology, they reported that the higher alcohol fuels would decrease PM mass and number emissions, although current technology direct injection fueling produces higher particle number and soot mass emissions than the PFI fueling as a result of liquid fuel wetting effects and insufficient air fuel mixing. Particulate emissions were clearly influenced by certain fuel parameters including oxygen content, hydrogen content, and aromatics content.

Lux Research: fuel cell vehicles lag other drivetrains in terms of cost of ownership; ICE and HEV lowest cost

24 November 2014

Based on an analysis of various cost of ownership scenarios for various drivetrains, including internal combustion engine (ICE) gasoline and diesel; hybrid (HEV); battery-electric (EV); plug-in hybrid electric (PHEV); and fuel cell vehicles, Lux Research concludes that fuel cell vehicles (FCVs) are “solidly in a laggard position.

The Lux analysts ran scenarios associated with operation and ownership, broken out into fuel cost alone; fuel cost plus operation, but excluding purchase or lease; and fuel cost plus operation, including purchase or lease (total ownership cost). When looking at fuel cost only, EVs lead the way due to the relatively low price of electricity, followed by various types of hybrids (HEVs and PHEVs). Fuel cell vehicles can match EV fuel costs at $3/kg dispensed H2—a price highly unlikely in near-term, Lux said.

EPA delays issuing 2014 RVO standards for RFS until sometime in 2015

21 November 2014

The US Environmental Protection Agency (EPA) will not finalize the 2014 applicable percentage standards (the 2014 Renewable Volume Obligations, RVOs) under the Renewable Fuel Standard (RFS) program until sometime next year. In a notice to be published in the Federal Register, the agency said that it intends to take action on the 2014 standards rule in 2015 prior to or in conjunction with action on the 2015 standards rule.

Because of the delay in issuing the 2014 RFS standards, EPA is moving the compliance demonstration deadline for the 2013 RFS standards to 2015. EPA will make modifications to the Moderated Transaction System (EMTS) to ensure that Renewable Identification Numbers (RINs) generated in 2012 are valid for demonstrating compliance with the 2013 applicable standards.

Volkswagen Group to invest $106 billion over next 5 years in Automotive Division

21 November 2014

The Volkswagen Group will invest a total of €85.6 billion (US$106 billion) in new models, innovative technologies and its global presence in its Automotive Division over the coming five years. Around two-thirds of the total investment amount will flow into increasingly efficient vehicles, drives and more environmentally friendly production.

Investments in property, plant and equipment, investment property and intangible assets, excluding capitalized development costs (capex) in the Automotive Division will amount to €64.3 billion (US$80 billion), on a level with the planning approved in the previous year for the period from 2014 to 2018. At €41.3 billion (US$51.3 billion)—roughly 64%—the Group will spend most of the total capex in the Automotive Division on modernizing and extending the product range for all its brands. The main focus will be on expanding the SUV range—in particular in the A/A0 class—as well as on modernizing part of the light commercial vehicle portfolio.

DOE reports progress on development of low-carbon and renewable sources of hydrogen production

21 November 2014

The US Department of Energy (DOE) Fuel Cell Technologies Office’ (FCTO) 2014 Hydrogen and Fuel Cells Program Annual Progress Report (earlier post)—an annual summary of results from projects funded by DOE’s Hydrogen and Fuel Cells Program—described progress in the field of hydrogen production.

The objective of the Hydrogen Production sub-program is to reduce the cost of hydrogen dispensed at the pump to a cost that is competitive on a cents-per-mile basis with competing vehicle technologies. Based on current analysis, this translates to a hydrogen threshold cost of <$4 per kg hydrogen (produced, delivered, and dispensed, but untaxed) by 2020, apportioned to <$2/kg for production only.

Iran negotiations, OPEC meeting loom for oil markets

21 November 2014

by Nick Cunningham of

As November draws to a close, there are two major events that could profoundly change the oil markets. With the clock ticking, the 5 permanent members of the UN Security Council plus Germany (P5 plus 1) are negotiating down to the wire with Iran over its nuclear program. The two sides have made substantial progress, but some difficult issues remain unresolved ahead of the November 24 deadline.

“We’re very keen to try to get to a deal, but not a deal at any price,” UK Foreign Secretary Philip Hammond said on November 17. “There will have to be very significant further movement by the Iranians if we’re going to be able to get to a deal.”
