The current research critically evaluates the technical, economic, and environmental performance of a Power-to-Liquid (PtL) system for production sustainable aviation fuel (SAF). This SAF comprises direct air capture (DAC) unit, an off-shore wind farm, alkaline electrolyser refinery plant (reverse water gas shift coupled with Fischer-Tropsch reactor). calculated carbon conversion efficiency, hydrogen Power-to-liquids efficiency are 88 %, 39.16 % 25.6 respectively. heat integration between DAC unit enhances system's energy performance, while units reduces demand fresh water. economic assessment estimates minimum jet selling price (MJSP) 5.16 £/kg. process is OPEX intensive due to electricity requirements, CAPEX dominated by unit. A Well-to-Wake (WtWa) life cycle (LCA) shows that global warming potential (GWP) equals 21.43 gCO2eq/MJSAF, highly dependent on upstream emissions electricity. Within 95 confidence interval, stochastic Monte Carlo LCA reveals GWP falls below UK mandate treshold 50 reduction compared fossil fuel. Moreover, resulting WtWa footprint 0.480 l/MJSAF, refinery's cooling requirements electricity's pose as main contributors. study concludes estimating required monetary value certificates different scenarios under guidelines.

Integrated CO2 capture and utilisation: A promising step contributing to carbon neutrality

Carbon Capture Science & Technology, Год журнала: 2023, Номер 7, С. 100116 - 100116

The release of CO2 into the atmosphere is problematic; however, it an abundant, renewable, and inexpensive carbon resource. In past, environmental problems caused by excessive emissions, such as global warming ocean acidification, have become increasingly severe. Carbon capture utilisation (CCU) has drawn intensive interest due to its capacity sequester utilise a source produce high-value chemicals fuels. However, state-of-the-art CCU exhibits poor economics technological complexity extensive energy input, multiple reactor configuration, sorbent transfer between reactors for regeneration. Integrated (ICCU) directly utilises CO2-containing exhaust gas in situ upgrades them valuable products highly intensified process, representing more direct promising path emission control. A series high-performance dual functional materials (DFMs) composed catalytic adsorbent sites succeeded various ICCU applications. this account, we first briefly introduced research background technology motivation developing Furthermore, conducted detailed description from three aspects: ICCU-methanation, ICCU-dry reforming methane (DRM) ICCU-reverse water shift reaction (RWGS). particular, investigated optimal adsorption specific characteristics solved problem temperature matching sites. addition, mechanism underlying been explored, effect interfering components on performance real plant flue gases future applications also analysed. Significantly, catalyst stability was effectively improved investigating causes deactivation. Finally, although conversion still preliminary stages, can see that current results already indicate prospects. In-situ high-value-added chemical feedstock will be very attractive application reducing greenhouse recycling resources. We are committed promoting industrialisation large-scale production technology.

A Review of Carbon Capture and Valorization Technologies

Energies, Год журнала: 2023, Номер 16(6), С. 2589 - 2589

Опубликована: Март 9, 2023

Global fossil fuel consumption has induced emissions of anthropogenic carbon dioxide (CO2), which emanated global warming. Significant levels CO2 are released continually into the atmosphere from extraction fuels to their processing and combustion for heat power generation including fugitive industries unmanaged waste management practices such as open burning solid wastes. With an increase in population subsequent rise energy demands generation, rate release is at a much faster than its recycling through photosynthesis or fixation, increases net accumulation atmosphere. A large amount emitted various sources plants, vehicles manufacturing industries. Thus, capture plays key role race achieve zero emissions, paving path decarbonized economy. To reduce footprints industrial vehicular attempt mitigate effects warming, several capturing valorization technologies have become increasingly important. Hence, this article gives statistical geographical overview other greenhouse gas based on source sector. The review also describes different mechanisms involved utilization pre-combustion, post-combustion, oxy-fuels technologies, direct air capture, chemical looping gasification, ionic liquids, biological fixation geological capture. discusses captured value-added products clean energy, chemicals materials (carbonates polycarbonates supercritical fluids). This highlights certain progressing some promising techniques.

Escalating carbon dioxide (CO2) emissions have intensified the greenhouse effect, posing a significant long-term threat to environmental sustainability. Direct air capture (DAC) has emerged as promising approach achieving net-zero future, which offers several practical advantages, such independence from specific CO2 emission sources, economic feasibility, flexible deployment, and minimal risk of leakage. The design optimization DAC sorbents are crucial for accelerating industrial adoption. Metal-organic frameworks (MOFs), with high structural order tunable pore sizes, present an ideal solution strong guest-host interactions under trace conditions.
