China also began to pay attention to it even though we still at a initial stage, primarily, understanding the hiomethane potential and development prospect, choosing appropriate biomass as the biomethane source is very important. In this work, the theoretical and practical biomethane producing potential from five main bio- mass resources in China were estimated with appropriate methods based on the data collected, and during cal- culation, two appropriate energy crops were assumed to be planted on marginal lands for biomethane production. Our estimation showed that the theoretical and practical biomethane potentials in China can reach to 888.78 and 316.30 billion m3 per year, agricultural waste should be the preferential development biomass, and planting energy crops on marginal lands is the most promising way to enhance biomethane production in China. Finally, biomethane is compared with natural gas, and the result showed that 48.15% of the practical biomethane potential can meet the total Chinese natural gas consumption in 2013.展开更多

In addition, the fossil fuel reserves is facing rapid depletion on the earth. Currently, most researches have concentrated on producing biogas for heating, lighting, drying, cooking but lack in researching on electricity production because the possibility of producing biogas at households are common at small scale. Studying on alternative energy sources to replace traditional fuel for electric power generation brings new chances and great opportunities for development. This study presents an assessment electric power generation via water hyacinths and agricultural waste. In this paper, the evaluation electric power is generated by operating internal combustion engines which use biogas fuel to replace traditional fuel （diesel, gasoline）. The results of the studies were demonstrated by experiments on the renewable energy production system at Hoa An Biotechnology Research and Experimental Center of Cantho University.展开更多

Renewable energy plays a decisive role in a cleaner energy production with less environmental impacts. In this new world scenario, several countries create incentive programs aiming to increase the renewable energy share in their energy balance. Biogas is an interesting example of a smart and rational use of organic waste material. Nevertheless, international experience shows that its production relays mainly on government incentives. This paper investigates what the Brazilian government role is to introduce and promote the biogas industry in the country. We estimate the production of agricultural waste energy using biogas derived from cattle and swine waste and analyze the Brazilian legal and regulatory framework for renewable energy, focusing on biogas production, transport and sale. The results point to an unexplored potential of the use of cattle and swine waste for biogas production in Brazil. However, this potential can only become a reality if some legal and regulatory issues are solved. Brazilian government agenda has to include not only filling the legal and regulatory blanks but also creating incentives for the use of biogas.展开更多
