Photoelectrochemical (PEC) systems are promising approaches for sustainable fuel processing. PEC devices, like conventional photovoltaic-electrolyzer (PV-EC) systems, utilize solar energy splitting water into hydrogen and oxygen. Contrary to PV-EC devices integrate the photoabsorber, ionic membrane, catalysts a single reactor. This integration of elements potentially makes simpler in design, increases efficiency, offers cost advantage, allows implementation with higher flexibility use. We present detailed techno-economic evaluation three different device designs. combine system-level analysis based on physical performance models (including degradation) stochastic methods uncertainty assessments, also considering use PV EC learning curves future scenarios. For hydrogen, we assess design options (utilizing liquid or vapor as reactant) compare them (anion cation exchange). show that current scenario, (with levelized 6.32 $/kgH2) located southern Spain not yet competitive, operating at 64% costs than PV-driven anion exchange systems. Our indicates plants' material size most significant factors affecting costs. designs economical designs, potential about 10% less reach 2 $/kgH2 target by 2040.

Gas fermentation using homoacetogenic consortia to convert CO2 into sustainable fuels and chemicals has emerged as a promising biotechnological route toward carbon neutrality. However, significant challenge is the low gas–liquid mass transfer rates due limited solubility of C1 gases. This study investigates enhancement high-pressure gas (HPGF) reactor embedded with electrodes, effectively overcoming barriers addressing sustainability through an innovative approach. H2 electron donor was conducted in pressurized fermenters (PFs) at varying partial pressures (pCO2-2, -3, -5 bar), while pressured electro-fermentation (PEF) used electrodes replace H2. The pCO2-PEF-5 condition achieved highest acetic acid productivity 2.8 g/L, followed by pCO2-PEF-3 2.65 representing 1.2 1.18 times higher yields than best PFs (pCO2-PF-3, 2.1 g/L), respectively. Additionally, PEF systems enhanced solventogenic activity, ethanol production reaching 1.4 g/L pCO2-PEF-5. substitution improved fixation conversion (pCO2-PEF-5: 67 mg/L/h, 77%), demonstrating viable strategy for conversion. thermodynamic analysis indicated more spontaneous synthesis compared PF systems. Bioelectrochemical assessments revealed charge rates, faradaic efficiency 48% pCO2-PEF-5, further supporting Especially, key genes Wood–Ljungdahl pathway (WLP) were upregulated systems, confirming that influences metabolic pathways favoring solvent production. A life cycle assessment (LCA) highlighted net emission reduction −7 kg equiv PEF-5 lower impact across endpoint categories, highlighting carbon-negative potential this From planetary boundary framework perspective, process operates within Holocene state reducing emissions, helps maintaining biosphere integrity, reduces atmospheric CO2, contributes minimally nitrogen phosphorus flows. signifies scaling processes. integration not only addresses limitations but also enhances productivity.

This perspective from members of the Energy & Fuels Division (ENFL) Industry Committee American Chemical Society (ACS) discusses ENFL's role and challenges to foster a sustainable equitable energy future by promoting research technological advancements in production, storage, utilization. Using bibliometric techniques, current trends are presented non-renewable renewable energies, storage grid modernization, hydrogen technologies, carbon capture, utilization, (CCUS). Recent International Agency (IEA) projections indicate that 2023 global investments clean increased 17% $1.7 trillion. However, conventional sources still account for over 80% consumption, share projected peak near 2030. Continued robust growth capacity expansions 2024 has shown solar photovoltaic (PV) wind driving substantial rise capacity. Nevertheless, dominate consumption. While liquids biomass remain limited, renewables supply only modest fraction total demand decade's end. Despite these practical limitations producing biomass, 20% final consumption 2030, up 13% 2023.
