Sustainability analysis of CO2 capture and utilization processes using a computer-aided tool

Monomers from CO2: Superbases as Catalysts for Formate‐to‐Oxalate Coupling

“…In addition, CO 2 can have a low or even negative cost and high abundance [15–17] . In the “OCEAN” project we use the CO 2 ‐to‐formate reaction and the formate product tree as a stepping stone towards large scale electrochemical conversion of CO 2 and H 2 O to syngas, the starting point for many downstream products, including chemicals, polymers, and fuels [7,18,19] . Polymers can be especially interesting as they allow for long‐term storage of sequestered CO 2 in materials [15,16] .…”

Process modelling and life cycle assessment coupled with experimental work to shape the future sustainable production of chemicals and fuels

“…Furthermore, studies often restrict the scope to environmental impact(s) tightly linked to the use of biomass and CO 2 as feedstock, focusing on global warming and fossil depletion metrics. 38,42,48,77,78,109,120,126,[159][160][161][162][163] However, the large-scale adoption of emerging technologies could unintendedly shift burdens across environmental categories or echelons in the product's supply chain. It was stressed that LCA studies on CCU products are not harmonized in terms of assumptions, scope, system boundaries and impact metrics, which makes comparisons challenging.…”

Apples and Apples: A Shortcut Assessment Framework for Early‐Stage Carbon Capture and Utilization Technologies Based on Efficiency, Feasibility, and Risk

“…Shortcut studies compare many alternatives on a low level of detail, in contrast to full‐scope studies that compare a few technology alternatives on a high level of detail. Various indicators are used in scientific, industry, and governmental literature, such as energy efficiency, [ 30 ] energy consumption or demand, [ 31–33 ] relative added value, [ 10,33–35 ] production volume or market potential, [ 10,34–37 ] economic limitations or feasibility, [ 10,36,37 ] substitution of fossil fuels, [ 10,35 ] mass of carbon or CO 2 utilized as a rate or potential, [ 10,31,34,35 ] CO 2 emissions reduction as a rate or potential, [ 33–35,37,38 ] health and safety, [ 10,34 ] cost of CO 2 utilized, [ 34 ] cost of CO 2 avoidance [ 38 ] and technology maturity or availability. [ 10,35,36 ] Related methodological papers propose generic frameworks on how to merge environmental assessment with TEA [ 39,40 ] or propose a detailed list of 140 indicators including data needs.…”
