A Comparative Science-Based Viability Assessment Among Current and Emerging Hydrogen Production Technologies

Applied Sciences, Journal Year: 2025, Volume and Issue: 15(2), P. 497 - 497

Published: Jan. 7, 2025

This research undertakes a comparative analysis of current and emerging hydrogen (H2) production technologies, evaluating them based on quantitative qualitative decision criteria. The criteria include cost H2 (USD/kg H2), energy consumption (MJ/kg global warming potential (kg CO2-eq/kg technology efficiency (%). encompass readiness level (TRL) availability supply chain materials (classified as low, medium, or high). To achieve these objectives, an extensive literature review has been conducted, systematically assessing the selected technologies against aforementioned insights synthesized from provide foundation for informed, science-based evaluation potentials techno-economic challenges that face in achieving 1-1-1 goal set by U.S. Department Energy (DOE) 2021. target aims USD 1/kg within one decade (by 2031), including costs associated with production, delivery, dispensing at fueling stations (HRSs). Also, DOE established interim 2/kg 2026. concludes among examined water electrolysis biomass waste valorization emerge most promising near-term solutions to meet DOE’s goal.

The condensation process of supercritical water gasification products in a bicubic supersonic nozzle

Physics of Fluids, Journal Year: 2025, Volume and Issue: 37(2)

Published: Feb. 1, 2025

The development of energy-efficient and clean supercritical water gasification product (SCWGP) separation technology has become one the bottlenecks in advancing technology. This study suggests utilizing a supersonic nozzle to condense separate H2 CO2 from SCWGP. flow condensation model are established for bicubic parametric nozzle, effects various operating conditions on SCWGP analyzed. liquid phase mass fraction at outlet is significantly influenced by inlet pressure temperature. approximate relationship between variations 0.065 per MPa, while temperature approximately –0.013 K. latent heat released during process significant impact distribution within nozzle. Inlet parameters have notable effect peak values positions nucleation droplet growth rates. condensed primarily concentrated near center outlet. efficiency strongly molar gas mixture, small amount N2 mixed little performance.
