In order to accurately anticipate the proficiency of downdraft biomass gasification linked with a water–gas shift unit produce biohydrogen, model based on an artificial neural network (ANN) approach is established estimate specific mass flow rate biohydrogen output plant different types biomasses and diverse operating parameters. The factors considered as inputs models are elemental proximate a...

Biohydrogen is a carbon-free alternative energy source, that can be obtained from fermentation of organic waste, biomass-derived sugars, and wastewater. This article reviews the current processes for fermentative biohydrogen production biomass including its appropriate storage transport challenges. The review showed comparison pretreatment methods across literature complicated fermentability te...

Abstract The utilisation of natural energy not only can reduce consumption in buildings but also lower carbon emissions from the use fossil fuel for building services. It is believed that with appropriate design and a good attitude users, role renewable reducing will be maximised. This study proposed implementation Zero Energy Buildings (ZEB) concept initial stage by considering buildings’ form...

BACKGROUND Hydrogenases catalyze reversible reaction between hydrogen (H2) and proton. Inactivation of hydrogenase by exposure to oxygen is a critical limitation in biohydrogen production since strict anaerobic conditions are required. While [FeFe]-hydrogenases are irreversibly inactivated by oxygen, it was known that [NiFe]-hydrogenases are generally more tolerant to oxygen. The physiological ...

UNLABELLED BACKGROUND Biohydrogen from cyanobacteria has attracted public interest due to its potential as a renewable energy carrier produced from solar energy and water. Anabaena siamensis TISTR 8012, a novel strain isolated from rice paddy field in Thailand, has been identified as a promising cyanobacterial strain for use as a high-yield hydrogen producer attributed to the activities of t...
