Energies, Journal Year: 2024, Volume and Issue: 17(16), P. 4148 - 4148

Published: Aug. 21, 2024

In recent years, global efforts towards a future with sustainable energy have intensified the development of renewable sources (RESs) such as offshore wind, solar photovoltaics (PVs), hydro, and geothermal. Concurrently, green hydrogen, produced via water electrolysis using these RESs, has been recognized promising solution to decarbonizing traditionally hard-to-abate sectors. Furthermore, hydrogen storage provides long-duration approach managing intermittency which ensures reliable stable electricity supply supports electric grid operations ancillary services like frequency voltage regulation. Despite significant progress, economy remains nascent, ongoing developments persistent uncertainties in economic, technological, regulatory aspects. This paper comprehensive review value chain, encompassing production, transportation logistics, methodologies, end-use applications, while identifying key research gaps. Particular emphasis is placed on integration into both grid-connected islanded systems, focus operational strategies enhance resilience efficiency over long short terms. Moreover, this draws case studies from pioneering projects inform that can accelerate adoption large-scale deployment technologies across diverse sectors geographies.

Energy management of hydrogen hybrid electric vehicles — A potential analysis

International Journal of Hydrogen Energy, Journal Year: 2024, Volume and Issue: 58, P. 1 - 13

Published: Jan. 19, 2024

The hydrogen combustion engine (H2ICE) is known to be able burn H2, producing no CO2 emissions and extremely low engine-out NOxeo emissions. In this work, the potential reduce through implementation of electric hybridization an H2ICE-equipped passenger car (H2-HEV), combined with a dedicated energy management system (EMS) discussed. Achieving H2 consumption are conflicting objectives, trade-off which depends on EMS can represented as Pareto front. dynamic programming algorithm used calculate Pareto-optimal calibrations for various driving missions. Through utilization calibration, H2-HEVs exhibit decrease by more than 90%, while, decreasing over 16%, compared comparable non-hybridized H2-vehicle. present paper represents initial analysis, suggesting that viable option towards CO2-free mobility

From CO₂ to Sustainable Aviation Fuel: Navigating the Technology Landscape

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(32), P. 12143 - 12160

Published: July 22, 2024

Sustainable jet fuel plays a crucial role in reducing aviation's carbon footprint, offering promising approach toward net-zero emissions the aviation sector. This work investigates pathways for producing fuels directly from CO2. Given early stage of many direct CO2 utilization technologies, identifying is essential. Our investigation focuses on three most important routes production, each which employs distinct intermediate compound. These are reverse water–gas shift and Fischer–Tropsch (RWGS-FT) route, methanol electrolysis employ syngas, methanol, ethylene as key intermediates, respectively. By performing comprehensive process simulations analyzing resulting energy intensity thermal efficiency these findings provide quantitative early-stage evaluations allow us to identify technical development requirements. results indicate that route exhibits lowest intensity, followed by RWGS-FT routes. H2 production accounts significant share demand The shows efficiency, while achieves 92% including recycle streams, highlighting its potential production. Furthermore, holds achieve close 100% requires significantly less feedstock. However, it faces challenges high demand. In addition, our study effects technology optimization, providing guideline research optimization.
