Electrification to reduce or eliminate greenhouse gas emissions is essential mitigate climate change. However, a substantial portion of our manufacturing and transportation infrastructure will be difficult electrify and/or continue use carbon as key component, including areas in aviation, heavy-duty marine transportation, the chemical industry. In this Roadmap, we explore how multidisciplinary approaches enable us close cycle create circular economy by defossilizing these difficult-to-electrify those that need carbon. We discuss two for this: developing alternatives improving ability reuse carbon, enabled separations. Furthermore, posit co-design use-driven fundamental science are reach aggressive reduction targets. To achieve net-zero emissions, must industries electrify. Developing needed provide non-fossil accelerate advances towards defossilization.

A Compact Review of Current Technologies for Carbon Capture as Well as Storing and Utilizing the Captured CO2

Processes, Год журнала: 2025, Номер 13(1), С. 283 - 283

Опубликована: Янв. 20, 2025

With the consequences of climate change becoming more urgent, there has never been a pressing need for technologies that can help to reduce carbon dioxide (CO2) emissions most polluting sectors, such as power generation, steel, cement, and chemical industry. This review summarizes state-of-the-art capture, instance, post-combustion, pre-combustion, oxy-fuel combustion, looping, direct air capture. Moreover, already established capture technologies, absorption, adsorption, membrane-based separation, emerging like calcium looping or cryogenic separation are presented. Beyond this also discusses how captured CO2 be securely stored (CCS) physically in deep saline aquifers depleted gas oil reservoirs, chemically via mineralization, used enhanced recovery. The concept utilizing (CCU) producing value-added products, including formic acid, methanol, urea, methane, towards circular economy will shortly discussed. Real-life applications, e.g., pilot-scale continuous methane (CH4) production from flue CO2, shown. Actual deployment crucial future explored real-life applications. aims provide compact view should considered when choosing store, convert informing researchers with efforts aimed at mitigating tackling crisis.

Understanding the Electrode–Electrolyte Interfaces of Ionic Liquids and Deep Eutectic Solvents

Langmuir, Год журнала: 2024, Номер 40(7), С. 3283 - 3300

Опубликована: Фев. 11, 2024

Developing unconventional electrolytes such as ionic liquids (ILs) and deep eutectic solvents (DESs) has led to remarkable advances in electrochemical energy storage conversion devices. However, the understanding of electrode-electrolyte interfaces these electrolytes, specifically liquid structure charge/electron transfer mechanism rates, is lacking due complexity molecular interactions, difficulty studying buried with nanometer-scale resolution, distribution time scales for various interfacial events. This Feature Article outlines standing questions field, summarizes some exciting approaches results, discusses our contributions probing electrified by impedance spectroscopy (EIS), surface-enhanced Raman (SERS), neutron reflectivity (NR). The related findings are analyzed within electrical double-layer models provide a framework ILs, DESs, and, more broadly, concentrated hydrogen-bonded electrolytes.

Abstract Amid a relentless global climate crisis, the 28th Conference of Parties (COP28) spotlighted Direct Air Carbon Capture (DACC) as key intervention to mitigate escalating temperatures and CO 2 levels. The Intergovernmental Panel on Climate Change (IPCC) underscores urgency this challenge, stipulating need for robust removal strategies. It sets daunting yet crucial target: capture 85 million metric tons by 2030, 980 2050, achieve net-zero emissions (IEA, Executive Summary—Direct 2022—Analysis. https://www.iea.org/reports/direct-air-capture-2022/executive-summary ). Despite imperative, existing 19 operational DAC facilities globally face significant barriers, including prohibitive costs stringent regulations, which impede their large-scale application (Ozkan et al.). Current status pillars direct air technologies. Iscience (2022). While COP28 stopped short delineating definitive roadmap DAC, article addresses vital aspect technology: processes’ substantial energy heat requirements, are integral efficiency economic viability. This illuminates pathways future technological evolution cost optimization through an in-depth analysis these thereby charting course toward more effective scalable infrastructure. Graphical abstract Highlights With atmospheric exceeding 420 ppm, clock is ticking crisis. offers revolutionary approach directly remove excess , acting critical tool in our fight sustainable future. However, current systems challenge high consumption. Continuous fan operation intake sorbent material regeneration, consuming nearly 2000–3000 kWh per ton captured, major contributors. Optimizing processes crucial. Advancements efficiency, system design that minimizes parasitic losses, seamless integration with renewable sources slashing DAC’s demands. By reducing its carbon footprint enhancing viability, advancements can unlock full potential become game-changer combating change securing cleaner planet. Discussion Given requirements DACC processes, what innovations necessary make efficient economically viable? Considering demands most promising avenues enhance technology's scalability cost-effectiveness? How limitations be overcome scale up effectively? What role could play meeting facilities, how might impact overall process? do technologies influence location infrastructure needs, particularly relation sinks? or currently being explored optimize challenges they terms implementation scaling? achieving targets, policy regulatory frameworks designed support development deployment energy-efficient solutions?
