Published: May 1, 2024

Abstract In the pursuit of sustainable energy solutions, hydrogen emerges as a promising candidate for decarbonization. The United States has potential to sell wind at record‐low price 2.5 cents/kWh, making production electricity up four times cheaper than natural gas. Hydrogen's appeal stems from its highly exothermic reaction with oxygen, producing only water byproduct. With an content equivalent 2.4 kg methane or 2.8 gasoline per kilogram, boasts superior energy‐to‐weight ratio compared fossil fuels. However, energy‐to‐volume ratio, exemplified by liquid hydrogen's 8.5 MJ.L −1 versus gasoline's 32.6 , presents challenge, requiring larger volume energy. addition, this review employs life cycle assessment (LCA) evaluate full cycle, including production, storage, and utilization. Through examination LCA methodologies principles, underscores importance in measuring environmental sustainability consumption. Key findings reveal diverse pathways, such blue, green, purple hydrogen, offering nuanced understanding their inventories. impact is explored, supported case studies illustrating implications. Comparative analysis across different pathways provides crucial insights decision‐making, shaping considerations. Ultimately, emphasizes LCA's pivotal role guiding economy toward low‐carbon future, positioning versatile carrier significant potential.

Current climate crisis makes the need for reducing carbon emissions more than evident. For this reason, renewable energy sources are expected to play a fundamental role. However, these not controllable, but depend on weather conditions. Therefore, green hydrogen (hydrogen produced from water electrolysis using energies) is emerging as key carrier solve problem. Although different properties of have been widely studied, some aspects such and footprint, well technological development regulatory framework in parts world analysed depth. This work performs data-driven analysis three pillars: maturity, technology. Results will allow evaluation deployment, both current situation expectations.

Study on g-C3N4/BiVO4 Binary Composite Photocatalytic Materials

Micromachines, Journal Year: 2023, Volume and Issue: 14(3), P. 639 - 639

Published: March 11, 2023

Recent studies have shown that the composite of semiconductor photocatalytic materials and g-C3N4 can effectively inhibit carrier recombination enhance adsorption performance materials, so photocatalyst has stronger activity. In this paper, three kinds graphitic carbon nitride with different morphologies were prepared using same precursor system by chemical cracking method. After characterization application, sample most significant activity was selected g-C3N4/BiVO4 heterostructure synthesized simple solvent evaporation method, then experiment carried out. The results show that, when content BiVO4 in is 1%, RhB highest, degradation rate could reach 90.4%. kinetic showed consistent quasi-primary model. cycle remains unchanged stable after four cycles. existence a binary heterojunction confirmed UV/Visible diffuse reflection (UV-DRS) photoluminescence (PL) experiments. Owing to Z-type charge process between g-C3N4, efficient separation achieved, thus enhancing capacity. This work provides new idea for study based on g-C3N4.
