Development of a mathematical model for predicting bio-slurry temperature and subsequent gas production rate for underground brick-built biogas digester using ambient air temperature forecast
… to implement anaerobic digestion technology for biogas production as a strategy to enhance energy supply and poverty eradication in rural communities. Underground, brick, and mortar built fixed dome type digesters are the most deployed small-scale biogas technology in sub-Saharan Africa (SSA) …

Viability of substitution of electricity with biogas for thermal uses at Neudamm campus of the University of Namibia
… in rural areas has led to increased interest in biogas technology, particularly in developing regions. This thesis presents the design and evaluation of a low-cost biogas digester for the Neudamm Campus of the University of Namibia. The study adresses the campus's energy cost and the …

Onpeak Market Dispatchable Energy From Megawatt Scale Fuel Cells And Stored Digester Methane
… revenue that would be collected from net metered biogas generation. When configured as recommended, these systems can provide up to 38 to 59% of the theoretical revenue from a spot market for the generator company (Genco) that dispatches the stored energy. It describes the implementation of the …

Insights into Adaptations of Biogas-Producing Microbial Communities from Taxonomic Profiling, Metagenomically Assembled Genomes and Analysis of the Methanogenic Isolate Methanothermobacter wolfeii SIV6
Biogas is an important renewable energy source in Germany. However, in the course of the German energy transition and for political and economic reasons, biogas plants must become more flexible with regard to varying residue-based substrates and thus changing process conditions, while ensuring a …

Life cycle sustainability assessment of next generation energy infrastructure in Africa: Is there a case for biohydrogen after biomethane?
… development of a hydrogen economy, since biogas processes can be modified to produce hydrogen instead of methane. It is unclear whether such a change would improve or worsen the environmental, social, and economic performance of such waste-to-energy installations. Earlier studies show that …
