On the role of system integration of carbon capture and mineralization in achieving net-negative emissions in industrial sectors

Abstract

Carbon capture and storage (CCS) is commonly acknowledged as a valuable technology for reducing industrial emissions. However, limited installation capacity raises questions about its ability to scale up effectively and...

Hydrogen, Ammonia and Symbiotic/Smart Fertilizer Production Using Renewable Feedstock and CO2 Utilization through Catalytic Processes and Nonthermal Plasma with Novel Catalysts and In Situ Reactive Separation: A Roadmap for Sustainable and Innovation-Based Technology

“…Carbon Capture and Storage [396], its integration within an industrial cluster [397] and its utilization of CO 2 at source are economically more advantageous than the removal of CO 2 from air as in Carbon Dioxide Removal (CDR) technologies [396], even after its release to the atmosphere. As indicated by Terlouw et al [398], the emissions avoided due to the substitution of certain processes (due to system expansion in LCA) can be easily misinterpreted as negative emissions, i.e., as carbon removal from the atmosphere.…”

The critical role of electricity storage for a clean and renewable European economy

“…Electricity balance and convergence criterion. The residual r i is calculated by summing the hourly contributions r i (h) (eqn ( 4)), which are obtained from the electricity balance expressed in eqn (5). The electricity balance is solved on an hourly basis and accounts for the electricity loss due to storage.…”

“…Transitioning toward a fully renewable energy system calls for a holistic and integrated approaches, 5 motivated by the uncertain nature of RE power generation. Indeed, the largest share of RE is weather-dependent with hourly, daily, and seasonal variations.…”

Mechanistic insights into the co-recovery of nickel and iron via integrated carbon mineralization of serpentinized peridotite by harnessing organic ligands

“…The rising need to create a decarbonized supply chain of energy critical metals motivates scientific advances in material-efficient pathways to harness earth abundant silicate resources. 1–4 The opportunity to fix anthropogenic CO 2 emissions via thermodynamically downhill carbon mineralization routes while co-recovering energy critical metals such as nickel and iron motivates scientific advances in accelerating these pathways. 1–3,5,6 Prior advances in this field were exclusively focused on carbon mineralization with limited attention being given to the co-recovery of energy critical metals that are present in earth abundant silicate resources such as serpentine (Mg 3 Si 2 O 5 (OH) 4 ) and olivine ((Mg,Fe) 2 SiO 4 ).…”

“…1–3,5,6 Prior advances in this field were exclusively focused on carbon mineralization with limited attention being given to the co-recovery of energy critical metals that are present in earth abundant silicate resources such as serpentine (Mg 3 Si 2 O 5 (OH) 4 ) and olivine ((Mg,Fe) 2 SiO 4 ). 1–4,7 However, recent advances have shown that organic ligands such as ethylenediaminetetraacetic acid (EDTA) are effective in facilitating the co-recovery of energy critical metals such as nickel, while enabling accelerated carbon mineralization. However, scalable realization of these pathways remains limited by the lack of mechanistic insights into the complex chemo-morphological interactions underlying the co-recovery of energy critical metals with inherent carbon mineralization.…”
