Assessing technical aspects of ocean alkalinity enhancement approaches

, 2023
Abstract. Ocean alkalinity enhancement (OAE) is an emerging strategy that aims to mitigate climate change by increasing the alkalinity of seawater. This approach involves increasing the alkalinity of the ocean to enhance its capacity to absorb and store carbon dioxide (CO2) from the atmosphere. This chapter presents an overview of the technical aspects

Assessing Environmental and Economic Performance for Port Hydrogen Fuel Transition: A Case Study of Vancouver Fraser Port Authority

Sustainable Development, EarlyView.
ABSTRACT As society continues to develop, hydrogen has emerged as a promising fuel for maritime decarbonization. This study develops an integrated environmental and economic assessment framework for the Vancouver Fraser Port Authority (VFPA) by combining life‐cycle assessment, levelized cost analysis, and multi‐criteria decision analysis across 36 ...

The efficiency and ocean acidification mitigation potential of ocean alkalinity enhancement on multi-centennial timescales [PDF]

Biogeosciences
Carbon dioxide removal (CDR) strategies such as ocean alkalinity enhancement (OAE) are likely required in addition to rapid emissions reductions to limit global warming to well below 2 °C.

Temporal grammars of novelty: How carbon removal entrepreneurs frame new technologies

Strategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary This paper assesses the ways in which carbon dioxide removal ventures frame their work. Drawing on George Herbert Mead's philosophy of the present, it conceptualizes temporal grammars of novelty as a framing strategy that involves connecting two points in time, namely present and future, to elaborate novelty.

Prospective site-specific life cycle assessment of ocean alkalinity enhancement

Environmental Research Letters
Ocean alkalinity enhancement (OAE) is a promising marine carbon dioxide removal (CDR) option, but its net climate benefit and wider environmental implications depend strongly on where, and how it is implemented as well as on decarbonized energy and ...

Reactivity of Oxidized Porous Silicon with Calcium Ion in Aqueous Media: Stability, pH Behavior, and Host‐Guest Strategies

Small, EarlyView.
Oxidized porous silicon, composed of an elemental silicon porous skeleton coated with a silica shell, reacts with aqueous Ca2+ to generate a mixed silica–calcium silicate matrix that is remarkably efficient at trapping small molecules. With an emphasis on the engineering of controlled‐release drug delivery systems, this study identifies the factors ...

Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...
