A Self‐Sustained System for Producing Green Hydrogen via Moisture Power

open access: yesCarbon Energy, EarlyView.
A multifunctional PAM‐PSSA‐MgCl2 gel enables a self‐powered Moisture‐Electricity‐Water‐Hydrogen system that harvests atmospheric water, generates electricity via moisture‐driven processes, and directly electrolyzes the collected water for hydrogen production. The material delivers 1.87 V, 450 μA cm−2 (MEG), and 1.318 g g−1 (AWH) water uptake, achieving

Impact of A‐Site Sr Substitution in LaFeO3 on Syngas Selectivity During Chemical Looping Dry Reforming of Methane (CL‐DRM)

open access: yesChemistry – A European Journal, EarlyView.
Sr doping regulates oxygen exchange and methane activation in LaFeO3, suppressing nonselective CH4 cracking and coke formation during CL‐DRM. La0.7Sr0.3FeO3 provides the optimal balance, delivering ∼40% CH4 conversion, an H2/CO ratio of 2, and >95% carbon balance.

Internal Carbon Cycles in the Steel Industry: Pathways for CO2 Management and Carbon Capture Utilization

open access: yesChemie Ingenieur Technik, EarlyView.
The steel industry accounts for about 7%‐9% of global CO2 emissions. While H2‐based direct reduction is a long‐term route, near‐term solutions are needed for existing plants. Internal carbon cycles reuse steelworks off‐gases and by‐products, enabling circular carbon use and supporting CCU integration.

First Operation Results of a Methanol Demonstration Plant With Real Steel Mill Gases

open access: yesChemie Ingenieur Technik, EarlyView.
A demonstration plant with industrial setup regarding length, diameter, boiling water cooling system and gas recycle was initially operated with cleaned blast furnace gas and compared with earlier experiments with bottle gases. Dynamic disturbances from the steel mill and gas cleaning unit were noticed and could be compensated by the control system ...

Comparative Assessment of Methanol Production Pathways From Steel Mill Gases

open access: yesChemie Ingenieur Technik, EarlyView.
This publication reviews the process concepts and assessments for converting steel mill gases into sustainable methanol, focusing on energy efficiency, and the regulatory framework. From an energy perspective, the production of methanol from BOFG and H2 separated from coke oven gas is of particular interest.

Impact of Trace Water on the Macroscopic Activity of Commercial Ammonia Cracking Catalysts Under Process‐Relevant Conditions

open access: yesChemie Ingenieur Technik, EarlyView.
This study evaluates how small water impurities—typical in ammonia cracking feedstock—affect catalyst performance at elevated pressures and temperatures. By decoupling permanent degradation from reversible inhibition, the findings highlight trace water as a significant factor for reliable catalyst screening and industrial ammonia cracking scale‐up ...

Techno‐Economic Analysis of Methanol Production From Steel Mill Gases

open access: yesChemie Ingenieur Technik, EarlyView.
A techno‐economic analysis for the synthesis of methanol from steel mill gases is carried out. Four different process concepts are defined and analyzed. The analysis yields levelized cost of methanol estimates between €1130 and €1419 t−1. Sensitivity analyses identify hydrogen production as the largest contributor to cost.
