Electricity-gas integrated energy system optimal operation in typical scenario of coal district considering hydrogen heavy trucks [PDF]

open access: yesarXiv, 2021
The coal industry contributes significantly to the social economy, but the emission of greenhouse gases puts huge pressure on the environment in the process of mining, transportation, and power generation. In the integrated energy system (IES), the current research about the power-to-gas (P2G) technology mainly focuses on the injection of hydrogen ...

Polyphenylene‐Based Anion Exchange Membranes with Robust Hydrophobic Components Designed for High‐Performance and Durable Anion Exchange Membrane Water Electrolyzers Using Non‐PGM Anode Catalysts

open access: yesAdvanced Energy Materials, EarlyView.
Terphenyl groups bearing meta‐phenylene and trifluoromethyl substituents as hydrophobic components are incorporated into a quaternized polyphenylene‐based backbone to produce AEMs. The fabricated thin membranes exhibit high ion conductivity, alkaline stability, and mechanical robustness.

Fundamental studies of catalytic gasification [PDF]

open access: yes, 1989
Studies of the catalytic steam gasification of carbon solids continued. In this project a considerable number of important findings have been made. Recently limited experimentation has been carried out on the production of C{sub 2} hydrocarbons from methane in the presence of Ca/K/Ni oxide catalysts and of oxygen, carbon and water.

Scalable and Integrated Photocatalytic Reactor Systems for Solar‐to‐Fuel Production: Photoredox and Photoreforming Processes

open access: yesAdvanced Energy Materials, EarlyView.
Solar fuels and other value‐added chemicals derived from light‐driven reactions are highly desirable. Although advanced photoactive materials have been reported, demonstrations of their feasibility in large‐scale production are needed. Hence, strategies and recent efforts in scaling up photocatalytic reactors and integrating them into comprehensive ...
