National and international political agendas have set clear priorities to reduce the use of energy in transport as well as their resulting emissions, and tackle the problems caused by oil scarcity and the escalating prices.
Climate change, coupled with the alarming consequences that high oil prices have on the economy, increase the concern of institutions at all levels. Various administrative bodies are aware of this situation and are promoting the use of alternative fuels in the transport sector.
Nevertheless, there are many obstacles that arise with any serious intention to make alternative fuels increase their market share; with cost, performance, and reliability being the key factors for the economical success of alternative fuels in road transport.
Researchers from the Universidad Politécnica de Madrid, involved in the European project STEPS (Scenarios for the Transport System and Energy Supply and their Potential Effects), have studied the situation of alternative fuels currently in use in Europe: natural gas, liquefied petroleum gas (LPG), hydrogen and biofuel. For each of these, they have examined the latest technical developments, their marketing potential, and the obstructions against their introduction in different market segments.
The conclusion that can be drawn from this study is that the difficulties for the introduction of these fuels in the market are common to all new technologies, and those can be overcome if the right policies are applied at an European level. It would generally be necessary to develop a strategy that includes a combination of policies for different sectors, as well as measures aimed to increase their efficiency.Of the policies, the study underlines those that affect the consumption of energy in the transport sector. These include market incentive policies, among which we can find tax reductions or loans for the use of certain energy sources, the change of the taxing tables for the acquisition and maintenance of vehicles; those aimed to increase the technology and efficiency of the vehicle, and those that seek a better efficiency of the transport system on a global scale.
This study has incorporated participating teams from 14 EU countries, including the University of Leuven, along with the researchers from the Centro de Investigación del Transporte - TRANSyT of the Universidad Politécnica de Madrid.

Species Richness – a false friend? Scientists want to improve biodiversity assessments

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
