Effectiveness of SEHRAC (storage-enhanced heat recovery room air-conditioner) for water heating in residential buildings in Hong Kong and elsewhere has been confirmed in previous studies. However, given these studies assumed a theoretical maximum recoverable heat, whether its use is still energy...

The potential for supercapacitors to expand the safe operating window of a wind-powered reverse osmosis membrane (wind-membrane) system by buffering short term wind fluctuations and intermittency was investigated. Experiments were carried out using synthetic brackish water (5500 mg/L NaCl) with...

In this paper, the intermittent experiment of a vertical ground source heat pump (GSHP) system is investigated and the corresponding geo-temperature variations are studied. The performance of the GSHP system under intermittent operation and the comparisons of different intermittent modes are...

In der Studie wurden die Auswirkungen der rasanten, regional sehr unterschiedlichen Ausdeh-nung der Biogaserzeugung und des dafür erforderlichen Energiepflanzenanbaus auf die innersektoralen Wechselwirkungen, die Boden- und Pachtmärkte sowie auf die Ernährungs- und Futtermittelindustrie...

One of the basic aspects of sustainable development strategy involves investments in green technologies, including energy production from renewable sources. Biomass, special organic waste which belongs to 'green sources' of energy can be used in the methane fermentation process of biogas...

A German-Brazilian research project investigates sugarcane as an energy plant in anaerobic digestion for biogas production. The aim of the project is a continuous, efficient, and stable biogas process with sugarcane as the substrate. Tests are carried out in a fermenter with a volume of 10 l. In...

Modified tapioca starch wastewater (MTSW) contains organic and inorganic matters that affected on biological wastewater treatment and biogas production. Especially, the wastewater from chemical modification processes contains high salinity that can inhibit microorganism activities. Zero valent...

The strong political support for biogas production in Germany over the past decade has greatly affected agricultural production, farms and land markets. This paper analyzes the effects of Germany's biogas policies on agricultural development by using the agent-based simulation model AgriPoliS....
