“…The study did not provide information to support its claim on integrating solar-heated water into the biogas digester. Rowayda et al [ 142 ] designed a pilot-scale digester to operate under mesophilic process conditions with a low-cost solar water heating system installed to increase biogas production in the digester for a poultry farm in Palestine equipped with a stirrer to ensure even temperature distribution. The greenhouse effect was used by Asheal et al [ 143 ] to regulate the temperature of a small-scale portable biogas digester.…”

“…Further, in digester effluent that operated at a temperature of 45 • C, E. Coli and total coliforms were found to be between 2-3 log units, which is lower than the world health organisation (WHO) guidelines for digested slurries [51]. Solar drying of digestate can reduce its total nitrogen concentration by volatilising ammonia, thus resulting in balanced chemical composition for fertilizer application [50]. As reported before, solar radiation can also be used for pre-treatment to enhance lignin degradation [18] and hence further improve the efficiency of AD.…”

“…Solar energy, apart from enhancing biogas production, can also be used to enhance pathogen removal from the digested slurry when faecal matter is used as feedstock [50]. Sun-drying of the digested slurry was found to increase pathogen (F. streptococcus) removal up to 3 log units.…”

Improvement of Biogas Quality and Quantity for Small-Scale Biogas-Electricity Generation Application in off-Grid Settings: A Field-Based Study

Small-scale electrical power generation (<100 kW) from biogas plants to provide off-grid electricity is of growing interest. Currently, gas engines are used to meet this demand. Alternatively, more efficient small-scale solid oxide fuel cells (SOFCs) can be used to enhance electricity generation from small-scale biogas plants. Most electricity generators require a constant gas supply and high gas quality in terms of absence of impurities like H2S. Therefore, to efficiently use the biogas from existing decentralized anaerobic digesters for electricity production, higher quality and stable biogas flow must be guaranteed. The installation of a biogas upgrading and buffer system could be considered; however, the cost implication could be high at a small scale as compared to locally available alternatives such as co-digestion and improved digester operation. Therefore, this study initially describes relevant literature related to feedstock pre-treatment, co-digestion and user operational practices of small-scale digesters, which theoretically could lead to major improvements of anaerobic digestion process efficiency. The theoretical preamble is then coupled to the results of a field study, which demonstrated that many locally available resources and user practices constitute frugal innovations with potential to improve biogas quality and digester performance in off-grid settings.

“…The calculated internal rate of return of the investment of 32.6% encourage the use of solar energy for heating requirement of bio waste reactors. Ali and Al-Sa'ed [174] monitored the biogas production of a Palestinian small-scale anaerobic digester of 0.5 m 3 treating poultry manure. The digester is assisted by a solar water heating system consisting of a 1.6 m 2 flat plate collector.…”

Anaerobic Digestion (AD) is a well-established process that is becoming increasingly popular, especially as a technology for organic waste treatment; the process produces biogas, which can be upgraded to biomethane, which can be used in the transport sector or injected into the natural gas grid. Considering the sensitivity of Anaerobic Digestion to several process parameters, mathematical modeling and numerical simulations can be useful to improve both design and control of the process. Therefore, several different modeling approaches were presented in the literature, aiming at providing suitable tools for the design and simulation of these systems. The purpose of this study is to analyze the recent advancements in the biomethane production from different points of view. Special attention is paid to the integration of this technology with additional renewable energy sources, such as solar, geothermal and wind, aimed at achieving a fully renewable biomethane production. In this case, auxiliary heat may be provided by solar thermal or geothermal energy, while wind or photovoltaic plants can provide auxiliary electricity. Recent advancements in plants design, biomethane production and mathematical modeling are shown in the paper, and the main challenges that these fields must face with are discussed. Considering the increasing interest of industries, public policy makers and researchers in this field, the efficiency and profitability such hybrid renewable solutions for biomethane production are expected to significantly improve in the next future, provided that suitable subsidies and funding policies are implemented to support their development.
