This paper presents a novel impedance-based approach to efficiently estimate the state of charge (SOC) of a Li-ion battery. By using an AC impedance analyzer, a database is constructed, containing records of AC impedance <i>versus</i> SOC. In practical applications, the SOC values can be found...

Fossil fuels comprise 93% of Malaysia’s electricity generation and account for 36% of the country’s 2010 Greenhouse Gas (GHG) emissions. The government has targeted the installation of 330 MW of biomass electricity generation capacity by 2015 to avoid 1.3 Mt of CO₂ emissions annually and...

We have found the following error in the authors’ information in this article, which was recently published in <i>Energies</i> [1]. On page 5273, the names of the authors are incorrect; they should be changed <i>from</i>:[...]

Heat flow and geothermal gradient of the sedimentary succession of the Western Canada Sedimentary Basin (WCSB) are mapped based on a large thermal database. Heat flow in the deep part of the basin varies from 30 mW/m² in the south to high 100 mW/m² in the north. As permeable strata are required...

Optimization of nutrient supplements<i> i.e.</i>, yeast extract (1, 3 and 5 g·L⁻¹), dried spent yeast (DSY: 4, 12 and 20 g·L⁻¹) and osmoprotectant (glycine: 1, 3 and 5 g·L⁻¹) to improve the efficiency of ethanol production from a synthetic medium under very high gravity (VHG) fermentation by<i>...</i>

Industrial energy efficiency has received increasing attention in many countries because of its importance in the pursuit of energy supply security, increased economic competitiveness and in the mitigation of greenhouse gases emissions. This paper aimed to evaluate the energy consumption...

This paper introduces the “Energy-Environmental Efficiency” concept of building a low-carbon dispatch model of wind-incorporated power systems from the perspective of environmental protection and low-carbon dispatch promotion based on the existing economic environmental dispatch. A rolling...

The aim of this paper is the determination of a concentrating thermo-photovoltaic (CPV/T) system dynamic model by means of the finite element method (FEM). The system consist of triple-junction InGaP/InGaAs/Ge (indium-gallium phosphide/indium-gallium-arsenide/germanium) solar cells connected to...

We report on studies of an inorganic electrolyte: LiAlCl₄ in liquid sulfur dioxide. Concentrated solutions show a very high conductivity when compared with typical electrolytes for lithium ion batteries that are based on organic solvents. Our investigations include conductivity measurements and...

The heat transfer analysis of hydrate-bearing sediment involved phase changes is one of the key requirements of gas hydrate exploitation techniques. In this paper, experiments were conducted to examine the heat transfer performance during hydrate formation and dissociation by a thermal method...
