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.

Current society prioritizes clean energy production (CEP) to meet diverse needs and achieve sustainability. research involves different aspects of CEP, but comprehensive is limited. Therefore, this paper aims improve researchers' integrated understanding the field reveal significant trends by using CiteSpace conduct a visualized bibliometric analysis CEP in past 20 years. Specifically, we aim analyze statistical characteristics, collaboration dynamics, status, hotspot evolutions; find that an increasingly focused hot field, with Asian institutions countries are more active collaborators; besides, most highly co-cited journals have high impact factors reputations, they related physics, chemistry, biology; furthermore, topics cover whole procedure been changing significantly over years; future, will integrate disciplines, new may occur, paradigm be collaborative, targeting specific segments engineering application-oriented. The important future renewable energy, lignocellulosic biomass, carbon capture, challenges. results help scholars understand field's knowledge comprehensively, effectively, efficiently.

Lipid content is an essential indicator which affects the operation performance and efficiency of anaerobic digestion system. This study investigated relationship between system stability lipid degradation during mesophilic process lipid-rich food waste. As experiment designed, hydraulic retention time was 30 days influent total solid (TS) concentration substrates kept at 10 %, in gradually increased from % to 60 (on TS basis). The proceeded successfully, achieving a methane yield 587 mL/g-VS (volatile solids) lipid/TS ratio 50 %. However, collapsed after exceeded It found that accumulation long-chain fatty acid not primary factor leading failure, as remained below 500 mg/L even Instead, C/N ratios resulting different contents significantly impacted stability. substrate reached 45.47, causing failure due imbalance alkalinity production VFAs accumulation. mechanism illustrated by carbon nitrogen distributions.
