Hybrid vehicles are only pale green

08.02.2008
Hybrid electric vehicles that run on both conventional gasoline and stored electricity can be no more than a stop gap until more sustainable technology is developed, according to researchers in France.

Writing in the Inderscience publication International Journal of Automotive Technology and Management, they suggest that the adoption of HEVs might even slow development of more sustainable fuel-cell powered electric vehicles.

Jean-Jacques Chanaron Research Director within the French National Centre for Scientific Research (CNRS) and Chief Scientific Advisor at the Grenoble School of Management and Julius Teske at Grenoble, question strongly whether the current acceptance of hybrid vehicle technology particularly in the USA is in any way environmentally sustainable.

The researchers have analyzed the spread of this technology including the non-financial drivers for its adoption. They point out that most manufacturers are rapidly integrating hybrid electric vehicles into their technology portfolio, despite the absence of significant profitability.

They add that the misinformed craze for hybrid vehicles especially in the USA, and increasingly in Japan and Europe, and potentially in China, could represent a red light for more innovative technologies, such as viable fuel-cell cars that can use sustainably sourced fuels, such as hydrogen. They concur with earlier studies that suggest that hydrogen fuel cells will not be marketable in high volumes before at least 2025. This could, however, be too late for some models of climate change and emissions reduction. They also point out that even fuel cell technology has its drawbacks and much of the marketing surrounding its potential has emerged only from the hydrogen lobby itself.

"There is a general convergence of strategies towards promoting hybrid vehicles as the mid-term solution to very low-emission and high-mileage vehicles," the researchers assert, "this is largely due to Toyota’s strategy of learning the technology, while building up its own ‘quasi-standard’, thanks to its high-quality and reliability reputation and its high market share on the North American market." They add that, "Such a convergence is based more on customer perception triggered by very clever marketing and communication campaigns than on pure rationale scientific arguments and may result in the need for any manufacturer operating in the USA to have a hybrid electric vehicle in its model range in order to survive."

Moreover, political pressures also play a significant part. The three major US manufacturers - GM, Ford, and Chrysler - recently urged President Bush to financially and politically support a national technological solution for hybrids; this was independent of the currently dominant solutions initiated by Toyota. The researchers concede that, "The quest for low emission, clean, and high-mileage vehicles is on its way and should be at the top of the manufacturers' agenda," they say. However, they suggest that the technology, marketing, and public perception leads to one overriding problem: Is a hybrid strategy sustainable in the long run? Chanaron and Teske think not.

The complexity and high cost of the hybrid technology is also playing against itself," they say, "There is a huge strategic dilemma for the key players of the automotive industry where a mistake in technology decision-making might turn even a big player into a take-over candidate. The next five years will provide industry observers with more accurate trends and success or failure factors."

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.

Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
