Analysis of the Regulatory Framework for the CCU Technology

Chemie Ingenieur Technik, EarlyView.
ABSTRACT Carbon capture and utilisation (CCU) is increasingly considered an important technology for achieving climate neutrality within the German and European legal framework. Recent developments, particularly the Carbon Dioxide Storage and Transport Act (KSpTG), aim to enable CO2 transport infrastructure and cross‐sector carbon management systems ...

Developments in the EU Emissions Trading System and Their Effects on CCU Pathways

Chemie Ingenieur Technik, EarlyView.
From an engineer's perspective, the development of the European emissions trading system is analyzed. Difficulties for the use of carbon dioxide, particularly from mixed carbon sources, can be traced back to regulations whose effects might be resolved in the upcoming EU ETS revision. ABSTRACT The analysis presented in this article focuses on provisions

Application of artificial neural network and general machine learning modelling on CO2 adsorption in moisture equilibrated South African high and medium rank coals

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the effect of moisture on CO2 adsorption in South African coals using both experimental and machine learning approaches. Three coal samples (SL, TN, and EM) with varying ranks (RoVmr: 3.49%, 1.26%, and 0.64%, respectively) were collected from different regions of South Africa.
