“…33,34 Electricity production is assumed to take place outside of the system boundary, and the analysis assumes that electricity can be purchased at a fixed price ($0.05/kW h in the base-case analysis, based on the levelized cost of solar electricity in a medium resource area). 35 Unit costs of other materials/utilities used in this process are given in Table S3, which, along with the process model, are used to calculate the variable operating cost (VOC) of the process. operating cost contributions is detailed in Table S5.…”

Electromicrobial production (EMP), where electrochemically generated substrates (e.g., H 2 ) are used as energy sources for microbial processes, has garnered significant interest as a method of producing fuels and other value-added chemicals from CO 2 . Combining these processes with direct air capture (DAC) has the potential to enable a truly circular carbon economy. Here, we analyze the economics of a hypothetical system that combines adsorbent-based DAC with EMP to produce n-butanol, a potential replacement for fossil fuels. First-principles-based modeling is used to predict the performance of the DAC and bioprocess components. A process model is then developed to map material and energy flows, and a techno-economic assessment is performed to determine the minimum fuel selling price. Beyond assessing a specific set of conditions, this analytical framework provides a tool to reveal potential pathways toward the economic viability of this process. We show that an EMP system utilizing an engineered knallgas bacterium can achieve butanol production costs of <$6/gal ($1.58/L) if a set of optimistic assumptions can be realized.

“…Thus, it could be instructive to compare co-optimized PV with electrocatalysis to photocatalysts. PV-electrocatalytic systems would require a solar energy intensity of E Elec-PV ≈ E Elec /η PV ≈1 GJ tonne −1 where current commercial PV is η PV ∼ 0.2 [47]. Thus, electrochemical and photochemical have comparable energy intensities when solar powered.…”

Methane, a potent greenhouse gas, is a significant contributor to global warming, with future increases in its abundance potentially leading to an increase of more than 1◦C by 2050 beyond other greenhouse gases if left unaddressed. To remain within the crucial target of limiting global warming to 1.5◦C, it is imperative to evaluate the potential of methane removal techniques. This study presents a scoping analysis of different catalytic technologies (thermal, photochemical and electrochemical) and materials to evaluate potential limitations and energy requirements. An analysis of mass transport and reaction rates is conducted for atmospheric methane conversion system configurations. For the vast majority of catalytic technologies, the reaction rates limit the conversion which motivates future efforts for catalyst development. An analysis of energy requirements for atmospheric methane conversion shows minimum energy configurations for various catalytic technologies within classic tube or parallel plate architectures that have analogs to ventilation and industrial fins. Methane concentrations ranging from 2 ppm (ambient) to 1000 ppm (sources, such as wetlands, fossil-fuel extraction sites, landfills etc.) are examined. The study finds that electrocatalysis offers the most energy efficient approach (∼0.2 GJ/tonne CO2e) for new installations in turbulent ducts, with a total energy intensity <1 GJ/tonne CO2e. Photocatalytic methane removal catalysts are moderately more energy intensive (∼2 GJ/tonne CO2e), but could derive much of their energy input from “free” solar energy sources. Thermal systems are shown to be excessively energy intensive (>100 GJ/tonne), while combining photovoltaics with electrochemical catalysts (∼1 GJ/tonne CO2e) have comparable energy intensity to photocatalytic methane removal catalysts.
