Blue and green ammonia production: A techno-economic and life cycle assessment perspective

iScience, Год журнала: 2023, Номер 26(8), С. 107389 - 107389

Опубликована: Июль 14, 2023

Blue and green ammonia production have been proposed as low-carbon alternatives to emissions-intensive conventional production. Although much attention has given comparing these alternatives, it is still not clear which process better environmental economic performance. We present a techno-economic analysis full life cycle assessment compare the economics impacts of blue address importance time horizon in climate change impact comparisons by employing Technology Warming Potential, showing that methane leakage can exacerbate short horizons. represent constrained renewable electricity availability scenario mitigation efficiency per kWh electricity. Our work emphasizes maintaining low natural gas for sustainability ammonia, potential technological advances further reduce photovoltaics-based ammonia.

Although direct generation of high-value complex molecules and feedstock by coupling ubiquitous small such as CO 2 N holds great appeal a potential alternative to current fossil-fuel technologies, suitable scalable efficient catalysts this end are not currently available yet be designed developed. To end, here we prepare characterize Sb x Bi 1-x O y clusters for urea synthesis from via C–N coupling. The introduction in the amorphous BiO changes adsorption geometry on catalyst O-connected C-connected, creating possibility formation products urea. modulated Bi(II) sites can effectively inject electrons into , promoting advantageous modification symmetry frontier orbitals involved rate-determining catalytic step.

Porous Organic Polymers‐Based Single‐Atom Catalysts for Sustainable Energy‐Related Electrocatalysis

Advanced Energy Materials, Год журнала: 2023, Номер 13(28)

Опубликована: Июнь 8, 2023

Abstract Single‐atom catalysts (SACs) have been emerging as attractive catalytic materials in electrocatalysis for sustainable energy storage and conversion. To realize the practical implementation of SACs, reliable support is highly imperative to stabilize atomically dispersed metals with strong metal–support interaction, tunable local electronic environment, favorable electron/mass transport. Thanks great designability tunability composition, structure, morphology, porous organic polymers (POPs) demonstrated grand promise appropriate platforms toward design SACs at molecular level fabrication a controlled manner. Herein, comprehensive overview recent advances elucidation general principles, effective synthesis approaches, fundamental mechanisms boosting development high‐performance POPs‐based electrocatalytic transformations provided. The authors first outline rationales using supports principles electrocatalysis, followed by discussing approaches utilizing POPs POPs‐derived nanocarbons host single‐atom metals. Then, state‐of‐the‐art their applications heterogeneous (ORR, OER, HER, CO 2 RR, NRR) are discussed, which focus on revealing structure–performance correlation mechanisms. Finally, challenges strategies associated rational suggested.

Reducing Iron Oxide with Ammonia: A Sustainable Path to Green Steel

Advanced Science, Год журнала: 2023, Номер 10(16)

Опубликована: Март 30, 2023

Iron making is the biggest single cause of global warming. The reduction iron ores with carbon generates about 7% dioxide emissions to produce ≈1.85 billion tons steel per year. This dramatic scenario fuels efforts re-invent this sector by using renewable and carbon-free reductants electricity. Here, authors show how make sustainable reducing solid oxides hydrogen released from ammonia. Ammonia an annually 180 million ton traded chemical energy carrier, established transcontinental logistics low liquefaction costs. It can be synthesized green release again through reaction. advantage connects it making, for replacing fossil reductants. that ammonia-based oxide proceeds autocatalytic reaction, kinetically as effective hydrogen-based direct reduction, yields same metallization, industrially realized existing technologies. produced iron/iron nitride mixture subsequently melted in electric arc furnace (or co-charged into a converter) adjust composition target grades. A novel approach thus presented deploying intermittent energy, mediated ammonia, disruptive technology transition toward making.
