An important ongoing debate in the literature is whether or not the relationship between food price per kilocalorie and energy density is real or spurious. No closure has come on this debate because no formal statistical tests have been performed. Rather, the arguments against a real...

In this paper, the performances of various lithium-ion chemistries for use in plug-in hybrid electric vehicles have been investigated and compared to several other rechargeable energy storage systems technologies such as lead-acid, nickel-metal hydride and electrical-double layer capacitors. The...

The increased activity in the field of Battery Electric Vehicles (BEVs) and Hybrid Electric Vehicles (HEVs) have led to an increase in standardization work, performed by both world-wide organizations like the IEC or the ISO, as by regional and national bodies such as CEN, CENELEC, SAE or JEVA....

Thermal energy storage (TES) is moving towards thermochemical materials (TCM) which present attractive advantages compared to sensible and phase change materials. Nevertheless, TCM are more complex to characterize at lab scale and also the implied technology, which belongs to the chemical...

Low energy density resulting from the limited solubility of conventional electroactive species in electrolyte solutions has been one of the most critical barriers in the viability of redox flow batteries. Here we report a novel positive electrolyte that consists of two redox couples, viz....

This paper we present an energy review of the waste generated by shrub species in soils of low fertility for use as fuel in a power plant. The residues analysed belong to the species: Rhamus alaternus, Ulex europaeus, Prunus spinosa, Smilax aspera, Erica sp., Rubus ulmifolius, and Pteridium...

This study investigated the characteristics of 26 varieties of biomass produced from forestry, agriculture, municipality, and industry in Taiwan to test their applicability in thermal conversion technologies and evaluation of enhanced energy efficiency. Understanding the reactivity of the tested...

The paper focuses on the issue of obesi- ty, which has become one of the most insidious world epidemics and a serious threat to global health. The aim is to highlight the relationships between obesity and the sustainability of the food system and to discuss the effectiveness of different...
