Energy consumption has always been a central issue for sustainable urban assessment and planning. Different forms of energy analysis can provide various insights for energy policy making. This paper brought together three approaches for energy consumption accounting, i.e., energy flow analysis...

Biogas engineering and the biogas-linked agricultural industries as a whole has been used as both a developmental strategy for rural new energy and an important part of renewable agriculture revolution in China. In this paper, we proposed a 3-level emergetic evaluation framework to investigate...

Oil security has become a major issue in China. This paper analyzes China’s oil security from the supply chain perspective, as the country faces challenges from an increasing reliance on imported oil, a fast-growing economy, the Malacca dilemma, and volatile international oil prices. To...

Bioenergy from crop residues is one of the prevailing sustainable energy sources owing to the abundant reserves worldwide. Amongst a wide variety of energy conversion technologies, crop residue gasification has been regarded as promising owing to its higher energy efficiency than that of direct...

Efforts have been made to establish a biogas-linked agricultural production mode to alleviate poverty and pressure on the environment in rural China. In this paper, we evaluate the performance of biogas engineering using emergy analysis in the context of a compound agricultural system. A set of...

An absorption power/cooling combined cycle is proposed, and a thermodynamic analysis of the cycle is performed using log p-T, log p-h and T-s diagrams. Based upon two performance criteria, the overall thermal-efficiency and exergy efficiency, the cycle has been analyzed by means of a simulation....

Hydrogen supersaturation in extreme-thermophilic (70°C) mixed culture fermentation (MCF) was demonstrated for the first time by membrane inlet mass spectrometry. It was found that hydrogen supersaturation ratio (RH2) increased dramatically (from 1.0 to 20.6) when H2 partial pressure (PH2) was...

Better performance can be achieved when the bare silicon solar cells are immersed into liquids for the enhanced heat removing. In this study, the performance of solar cells immersed in liquids was examined under simulated sunlight. To distinguish the effects of the liquid optic and electric...

The biogas upgrading is necessary for its application, and alkali CO2 adsorption is one efficient method. In this study, a coupled system, bipolar membrane electrodialysis (BPMED)–microbial fuel cell (MFC), was proposed for alkali production, which could also realize electricity in situ...
