A Review of Carbon Capture and Valorization Technologies

Energies, Journal Year: 2023, Volume and Issue: 16(6), P. 2589 - 2589

Published: March 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).
