“…Smaller CO 2 RR plants may also be better suited to the scale of “stranded” renewable energy resources which are difficult to connect to the power grid if a proximate carbon source can be found. − Similarly, smaller CO 2 RR plants would have access to more CO 2 sources. , For example, a 3,150 tonne C 2 H 4 /year plant would require 16,300 tonne CO 2 /year, and 89% of large industrial emitters in the United States (not including power plants) could supply sufficient CO 2 for this scale . A more distributed production method could also minimize the likelihood of supply chain issues across international borders, while smaller plants may reduce financial risk and facilitate easier and faster project financing, especially for the first deployment …”

The decarbonization of the chemical industry is essential to mitigate carbon dioxide (CO2) emissions. Ethylene (C2H4) is the highest production petrochemical globally. When powered by renewable electricity, the electrochemical conversion of CO2 to C2H4 offers a promising route to low carbon C2H4 production. We perform a detailed techno-economic assessment (TEA) of the CO2 reduction reaction (CO2RR) process, converting CO2 from an industrial point source to polymer-grade C2H4. We pair the CO2 electrolyzer with industrially mature upstream and downstream separation technologies in an Aspen Plus model. This comprehensive approach enables us to assess the valorization of both gas and liquid byproduct streams at commercial specification and assess the viability of these processes as a function of scale. We demonstrate that a minimum plant size of ∼3,000 tonne C2H4/year is needed to achieve economies of scale among the upstream and downstream processes. This minimum plant size is ∼200-fold smaller than that of conventional C2H4 plants, coincides with that of typical utility-scale solar installations (∼25 MW), and could enable a more distributed model of chemical production going forward. We further highlight technical and economic enablers that would increase the profitability of the CO2RR to C2H4 technology.

Development finance needs to be better aligned with climate change objectives, and many experts see net zero portfolio targets as a powerful way to achieve this. This paper explores the operational implications of net zero portfolio targets for development finance institutions (DFIs). We set out an agenda to move development finance towards net zero goals in a way that acknowledges development concerns. These include (1) setting context‐specific emissions pathways with granular bottom‐up data and emphasising climate‐development win‐wins; (2) dealing with inertia and lumpiness in the portfolio through ‘when’ flexibility (multiyear carbon budgets) and ‘where’ flexibility (sharing of carbon space); (3) encouraging transition projects through future‐emissions accounting and transition credits; (4) managing climate‐development and other trade‐offs with an internal carbon price and ESG standards; and (5) accounting for emissions after project‐end with monitoring and legal provisions.
