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.

Research Progress and Reaction Mechanism of CO2 Methanation over Ni-Based Catalysts at Low Temperature: A Review

Catalysts, Journal Year: 2022, Volume and Issue: 12(2), P. 244 - 244

Published: Feb. 21, 2022

The combustion of fossil fuels has led to a large amount carbon dioxide emissions and increased greenhouse effect. Methanation can not only mitigate the effect, but also utilize hydrogen generated by renewable electricity such as wind, solar, tidal energy, others, which could ameliorate energy crisis some extent. Highly efficient catalysts processes are important make CO2 methanation practical. Although noble metal exhibit higher catalytic activity CH4 selectivity at low temperature, their large-scale industrial applications limited high costs. Ni-based have attracted extensive attention due activity, cost, abundance. At same time, it is great importance study mechanism on in designing high-activity stability catalysts. Herein, present review focused recent progress key parameters including essential nature nickel active sites, supports, promoters, preparation methods, elucidated reaction design with temperature well investigation areas that deserve further study.

Two-Stage Anaerobic Digestion for Green Energy Production: A Review

Processes, Journal Year: 2025, Volume and Issue: 13(2), P. 294 - 294

Published: Jan. 21, 2025

Anaerobic digestion (AD) is a biotechnological process in which the microorganisms degrade complex organic matter to simpler components under anaerobic conditions produce biogas and fertilizer. This has many environmental benefits, such as green energy production, waste treatment, protection, greenhouse gas emissions reduction. It long been known that two main species (acidogenic bacteria methanogenic archaea) community of AD differ aspects, optimal for their growth development are different. Therefore, if performed single bioreactor (single-phase process), selected taking into account slow-growing methanogens at expense fast-growing acidogens, affecting efficiency whole process. led two-stage (TSAD) recent years, where processes divided cascade separate bioreactors (BRs). division consecutive BRs leads significantly higher yields two-phase system (H2 + CH4) compared traditional single-stage CH4 production review presents state art, advantages disadvantages, some perspectives (based on more than 210 references from 2002 2024 our own studies), including all aspects TSAD—different parameters’ influences, types bioreactors, microbiology, mathematical modeling, automatic control, energetical considerations TSAD processes.
