Abstract The Ukraine conflict has put critical pressure on gas supplies and increased the price of fertilisers. As a consequence, biogas gained remarkable attention as local source both for energy biofertiliser agriculture. Moreover, climate change-related damage incentivises all sectors to decarbonise integrate sustainable practices. For instance, anaerobic digestion allows decarbonisation optimal waste management. Incorporating system in each country would limit global warming 2 °C. If suitable policies mechanisms are implemented, industry could reduce greenhouse emissions by 3.29–4.36 gigatonnes carbon dioxide equivalent, which represent about 10–13% emissions. Here, we review role sector capturing methane mitigating associated with outputs. Since impurities can cause severe practical difficulties storing grid delivering systems, present upgrading technologies that remove or consume raw biogas, achieve minimum 95% content. We discuss hydrogen-assisted biological sequestration converting biomethane via utilising hydrogen generated primarily through other renewable sources such water electrolysis photovoltaic solar facilities wind turbines. This conceptual shift 'power gas' excess grids. By produced during into additional biomethane, potential meet 53% demand fossil natural gas. also evaluate digestate from systems producing biochar, be used directly indirectly biomethanation enhancement, upgrading, cleaning material.

Nanobubble technology applications in environmental and agricultural systems: Opportunities and challenges

Critical Reviews in Environmental Science and Technology, Год журнала: 2022, Номер 53(14), С. 1378 - 1403

In recent years, there has been growing interest in the varied applications of nanobubble technology. Given their unique physicochemical properties, such as minuscule size (< 1 µm), surface charge, and high internal pressure, nanobubbles (NB) could provide new opportunities fields environmental engineering (including remediation, water treatment, aerobic fermentation, anaerobic digestion, algal biomass production), agriculture agronomy, horticulture, aquaculture, aquaponics, bioponics, hydroponics). addition, applying NB-derived reactive oxygen species (ROS) can inactivate pathogens remove harmful microorganisms on food, persistent organic pollutants from wastewater (removal efficacies > 60%). NB technology also maintain aqueous phase dissolved levels compared to conventional aeration, demonstrated hydroponics intensive crop farming, where NB-treated led increases plant yields (10–40%). However, a concise comprehensive source information fundamental mechanisms involving is lacking. As advance into biological frontier, these serve critical knowledge areas toward understanding NB–biomolecular cellular action. mass transfer performance not stringently assessed. To summarize current understanding, this review provides an updated, in-depth discussion technologies for various agricultural fields. Mechanistic details focusing electrostatic hydrophobic attachment, formation ROS, gas–liquid are discussed. This further outlines challenges concludes with important research needs

Effects of Temperature Shifts on Microbial Communities and Biogas Production: An In-Depth Comparison

Fermentation, Год журнала: 2023, Номер 9(7), С. 642 - 642

Опубликована: Июль 8, 2023

Temperature plays a significant role in anaerobic digestion (AD) as it affects the microbial communities and ultimately controls efficiency of process. Few studies have looked at temperature-adjusted AD, but is unclear how temperature shifts affect biogas production dynamics microorganisms involved methanogenesis. This study tested two shift scenarios fed-batch mode using anaerobically digested sewage sludge glucose-based substrate. The first scenario was acclimatized to upshifting temperatures from 42 °C 48 while second downshifting 55 45 °C. Both resulted decrease production, especially upshifted experienced maximum 83%, downshifted 16–33% methane production. Next-generation 16S rRNA sequencing revealed domination Methanoculleus scenario. However, low correlation between number other hydrogenotrophic methanogens indicates inhibition pathway. showed better due substantial acetoclastic Methanosaeta abundance sulfate-reducing bacteria. Hence, communities, significantly affecting performance.

Biological Aspects, Advancements and Techno-Economical Evaluation of Biological Methanation for the Recycling and Valorization of CO2

Energies, Год журнала: 2022, Номер 15(11), С. 4064 - 4064

Опубликована: Июнь 1, 2022

Nowadays, sustainable and renewable energy production is a global priority. Over the past decade, several Power-to-X (PtX) technologies have been proposed to store convert surplus of energies into chemical bonds chemicals produced by different processes. CO2 major contributor climate change, yet it also an undervalued source carbon that could be recycled represents opportunity generate energy. In this context, PtX would allow for valorization fuels while reducing greenhouse gas (GHG) emissions. With work we want provide up-to-date overview biomethanation as technology considering biological aspects main parameters affecting its application scalability at industrial level. Particular attention will paid concept CO2-streams integration process with energies. Aspects related new promising such in situ, ex hybrid underground methanation discussed, connection recent cases. Furthermore, technical economic feasibility critically analyzed highlight current options limitations implementing process.
