Exploratory Review on Environmental Aspects of Enhanced Weathering as a Carbon Dioxide Removal Method

Minerals, Год журнала: 2024, Номер 14(1), С. 75 - 75

Опубликована: Янв. 8, 2024

The accumulation of carbon dioxide in the atmosphere due to fossil fuel burning and deforestation has caused global warming an increase extreme weather events. To complement shift towards clean energy, it is crucial adopt methods for removal, known as negative emission technologies. Enhanced weathering one such approach that involves accelerating natural process rock by spreading finely ground rocks over large areas, agricultural land or coastal areas. This exploratory review paper provides overview fundamental mechanisms behind enhanced weathering, outlines techniques its implementation. environmental benefits are highlighted, including improvement soil fertility. Furthermore, potential impacts on ecosystems biodiversity examined, along with effects water, air quality. also considers risks challenges associated large-scale implementation long-term stability weathering. Additionally, integration Sustainable Development Goals explored, co-benefits trade-offs other sustainability objectives. conclude, this summarizes key findings proposes avenues further research field

Direct air capture (DAC) vs. Direct ocean capture (DOC)–A perspective on scale-up demonstrations and environmental relevance to sustain decarbonization

Chemical Engineering Journal, Год журнала: 2024, Номер 497, С. 154421 - 154421

Опубликована: Июль 31, 2024

As the atmospheric concentration of CO2 steadily increases and world grapples with pressing challenges global warming, international research communities are actively exploring inventive technologies to combat adverse effects elevated levels. An important challenge in this context is extract directly from atmosphere. Consequently, capturing last seawater crucial due its impact on delicate balance marine ecosystems potential consequences for climate regulation. While DAC DOC show towards combating change, including high operational costs need further technological advancements persist. This paper critically discusses status, challenges, scalability at pilot or industrial scale. Key include capital costs, energy demands, integrating green sources reduce environmental impact. The review emphasizes techno-economical benchmarking analyses evaluate feasibility large-scale deployment their effectiveness mitigating emissions acting as tools delocalized production.

A comprehensive review of enhanced in-situ CO2 mineralisation in Australia and New Zealand

International Journal of Coal Geology, Год журнала: 2023, Номер 276, С. 104316 - 104316

Опубликована: Июль 25, 2023

The urgent need to accelerate permanent anthropogenic carbon dioxide (CO2) abatement has led a growing interest in in-situ CO2 mineralisation globally. This review outlines the progress of Australia and New Zealand, while focusing on potential sink reservoirs for mineralisation, including magnesium-rich calcium-rich ultramafic mafic rocks. These rock types are abundant various regions across both countries. first begins by highlighting current status Australian Zealand emissions national goals. It then previews currently funded capture, utilisation, storage (CCUS) projects countries discusses where stands complement other methods. Secondly, it details different mechanisms within selected types/complexes followed discussion limitations advantages each major type/complex countries, relative distances between deposits emission hotspots. Finally, this we examine governmental funding perception enhanced two An example Mount Keith Ultramafic Complex (MKUC) is also presented, which shows relationship permeability, expected injection, estimated cost per ton direct pumping into low permeability Peridotite deposits. results show an inversely proportional injection rate, thus stored. calculations clearly demonstrate that limiting factor not availability but rather significant government incentives present attractive breakeven can compete market. slight advantage due 2-fold higher pricing compared Australia.

Potential Environmental Impacts and Management Strategies for Metal Release during Ocean Alkalinity Enhancement Using Olivine

Environmental Science & Technology, Год журнала: 2025, Номер unknown

Опубликована: Янв. 8, 2025

Ocean alkalinity enhancement (OAE) based on enhanced weathering of olivine (EWO) is a promising marine carbon dioxide removal (mCDR) technique. Previous research primarily focuses the toxicological effects potentially toxic metals (PTMs) released from olivine. In this Perspective, we explore overlooked impacts EWO environmental media in two scenarios: applied to beaches/shallow continental shelves and offshore dispersion by vessels. We analyze potential migration pathways iron PTMs (e.g., nickel chromium) after their release, interactions with manganese oxides sediments, causing secondary contamination. Additionally, propose mitigation strategies prevent PTM concentrations exceeding local quality standards, including use alkalization equipment control levels. This Perspective underscores need for thorough assessments prior large-scale implementation ensure sustainability efficacy mCDR efforts.

Unveiling the complexities of sustainable development: An investigation of economic growth, globalization and human development on carbon emissions in 64 countries

Sustainable Development, Год журнала: 2023, Номер 32(4), С. 3612 - 3639

Опубликована: Дек. 27, 2023

Abstract To achieve Sustainable Development Goals, countries face the challenge of expanding economic activities while mitigating pollution. Using panel autoregressive distributed lag and non‐linear approach, this study investigates effects globalization, development, human industrialization, non‐renewable energy, population density on carbon emissions (CO 2 ) 64 countries. This validates Environmental Kuznets Curve hypothesis in upper‐ lower‐middle‐income However, low‐income exhibit a U ‐shaped relationship, high‐income have successfully mitigated CO to some extent. The analysis shows bidirectional causality between other variables, except for one‐way from globalization emissions. Manufacturing depends conventional energy sources, indicating need policies promote renewable sources. findings significant policy implications enhancing environmental sustainability achieving sustainable growth SDGs.
