Current status of CO2 capture with ionic liquids: Development and progress

Fuel, Год журнала: 2023, Номер 344, С. 128102 - 128102

Опубликована: Март 15, 2023

Global warming triggered by greenhouse gas (GHG) emissions, particularly carbon dioxide (CO2), significantly influences climate change and has become a common environmental issue recently. The current amine-based technologies (ABTs) for CO2 capture (CAPCO2) have high energy demand, low absorption, desorption rates, are less environmentally sustainable due to emissions of volatile solvents. Therefore, the development friendly CAPCO2 materials and/or processes is growing area research. utilization ionic liquids (ILs) recently attracted attention. unique characteristics ILs, such as their vapor pressure affinity well volatility make them viable substitute existing processes. This work provides comprehensive overview accomplishments challenges during use ILs CAPCO2. Review also outlines mechanisms with at molecular level, properties characterization CO2/IL systems, effect operating conditions on uptake (UPCO2) capacity ILs. It emphasizes impact cations, anions, functional groups solubility ((SCO2)) in biodegradability toxicity Additionally, recent advances IL membrane technology considered. Lastly, contribution simulations create assess was reviewed.

Socio-technical barriers to domestic hydrogen futures: Repurposing pipelines, policies, and public perceptions

Applied Energy, Год журнала: 2023, Номер 336, С. 120850 - 120850

Опубликована: Фев. 22, 2023

The feasibility of the global energy transition may rest on ability nations to harness hydrogen's potential for cross-sectoral decarbonization. In countries historically reliant natural gas domestic heating and cooking such as UK, hydrogen prove critical meeting net-zero targets strengthening security. response, UK government is targeting industrial decarbonization via hydrogen, with parallel interest in deploying hydrogen-fueled appliances businesses homes. However, prospective futures, especially transition, face multiple barriers which reflect dynamics achieving economies scale social acceptance. Addressing these challenges calls a deep understanding socio-technical factors across different scales economy. this paper develops systems framework overcoming applied context. demonstrates that future strategies should account interactions between political, techno-economic, technical, market, dimensions transition. techno-economic feasibility, right policies will be needed create an even playing field green technologies, while also supporting stakeholder symbiosis consumer buy-in. Future studies grapple how effective repurposing pipelines, policies, public perceptions can aligned accelerate development economy, maximum net benefits society environment.

Comprehensive review of development and applications of hydrogen energy technologies in China for carbon neutrality: Technology advances and challenges

Energy Conversion and Management, Год журнала: 2024, Номер 315, С. 118776 - 118776

Опубликована: Июль 13, 2024

Concerning the transition from a carbon-based energy economy to renewable economy, hydrogen is considered an essential carrier for efficient and broad systems in China near future. aims gradually replace fossil fuel-based power generation with technologies achieve carbon neutrality by 2060. This ambitious undertaking will involve building industrial production chain spanning production, storage, transportation, utilisation of 2030 (when China's peak be reached). review analyses current status technological R&D industry. Based on published data open literature, we compared costs emissions grey, blue, green production. The primary challenges concerning transportation storage are highlighted this study. Given that result using fuels, provide overview advances hydrogen-to-power industry technology R&D, including hydrogen-related technology, fuel cells, internal combustion engines, gas turbines, catalytic liquid carriers (e.g. ammonia, methanol, ethanol).
