The global energy transition towards a carbon neutral society requires profound transformation of electricity generation and consumption, as well electric power systems. Hydrogen has an important potential to accelerate the process scaling up clean renewable energy, however its integration in systems remains little studied. This paper reviews current progress outlook hydrogen technologies their application for production, re-electrification storage. characteristics electrolysers fuel cells are demonstrated with experimental data deployments storage, power-to-gas, co- tri-generation transportation investigated using examples from worldwide projects. techno-economic status these applications is presented, which cost, efficiency durability identified main critical aspects. also confirmed by results statistical analysis literature. Finally, conclusions show that continuous efforts on performance improvements, scale ramp-up, technical prospects political support required enable cost-competitive economy.

Recent advances in solid oxide cell technology for electrolysis

Science, Journal Year: 2020, Volume and Issue: 370(6513)

Published: Oct. 9, 2020

In a world powered by intermittent renewable energy, electrolyzers will play central role in converting electrical energy into chemical thereby decoupling the production of transport fuels and chemicals from today's fossil resources decreasing reliance on bioenergy. Solid oxide electrolysis cells (SOECs) offer two major advantages over alternative technologies. First, their high operating temperatures result favorable thermodynamics reaction kinetics, enabling unrivaled conversion efficiencies. Second, SOECs can be thermally integrated with downstream syntheses, such as methanol, dimethyl ether, synthetic fuels, or ammonia. SOEC technology has witnessed tremendous improvements during past 10 to 15 years is approaching maturity, driven advances at cell, stack, system levels.

An overview of water electrolysis technologies for green hydrogen production

Energy Reports, Journal Year: 2022, Volume and Issue: 8, P. 13793 - 13813

Published: Oct. 25, 2022

Decarbonizing the planet is one of major goals that countries around world have set for 2050 to mitigate effects climate change. To achieve these goals, green hydrogen can be produced from electrolysis water an important key solution tackle global decarbonization. Consequently, in recent years there increase interest towards production through process large-scale implementation renewable energy-based power plants and other industrial, transportation applications. The main objective this study was provide a comprehensive review various technologies especially on electrolysis. In review, their techno-commercial prospects including cost, along with developments electrode materials, challenges were summarized. Further some most successful results also described. Moreover aims identify gaps research development perspective. addition, commercial electrolyzer performances limitations described possible solutions cost-effective Finally, we outlined our ideas, driving This information will future directions road map development/implementation commercially viable projects.

Hydrogen Production Technologies: From Fossil Fuels toward Renewable Sources. A Mini Review

Energy & Fuels, Journal Year: 2021, Volume and Issue: 35(20), P. 16403 - 16415

Published: Oct. 7, 2021

The global economic growth, the increase in population, and advances technology lead to an increment primary energy demand. Considering that most of this is currently supplied by fossil fuels, a considerable amount greenhouse gases are emitted, contributing climate change, which reason why next European Union binding agreement focused on reducing carbon emissions using hydrogen. This study reviews different technologies for hydrogen production renewable non-renewable resources. Furthermore, comparative analysis performed renewable-based evaluate economically energetically more promising. results show how biomass-based allow similar yield compared those obtained with water-based but higher efficiencies lower operational costs. More specifically, biomass gasification steam reforming proper balance between studied parameters, being technique allows yields, while energy-efficient. Nevertheless, application as vector future requires both use feedstocks sustainable source. combination would potentially produce green dioxide emissions, limiting and, thus, achieving so-called economy.

Cell-free chemoenzymatic starch synthesis from carbon dioxide

Science, Journal Year: 2021, Volume and Issue: 373(6562), P. 1523 - 1527

Published: Sept. 23, 2021

Starches, a storage form of carbohydrates, are major source calories in the human diet and primary feedstock for bioindustry. We report chemical-biochemical hybrid pathway starch synthesis from carbon dioxide (CO2) hydrogen cell-free system. The artificial anabolic (ASAP), consisting 11 core reactions, was drafted by computational design, established through modular assembly substitution, optimized protein engineering three bottleneck-associated enzymes. In chemoenzymatic system with spatial temporal segregation, ASAP, driven hydrogen, converts CO2 to at rate 22 nanomoles per minute milligram total catalyst, an ~8.5-fold higher than maize. This approach opens way toward future chemo-biohybrid CO2.
