Thermodynamics of Marine Carbon Dioxide Removal
ECS Meeting AbstractsIn recent years, marine carbon removal technologies have gained attention as a means of reducing greenhouse gas concentrations. One family of these technologies are electrochemical systems, which employ Faradaic reactions to drive alkalinity-swings and enable dissolved inorganic carbon (DIC) removal as gaseous CO

(Invited) Electrochemical Marine Carbon Dioxide Removal (mCDR)
ECS Meeting AbstractsEbb Carbon is developing an electrochemical system to safely remove carbon dioxide from the atmosphere and store it in the ocean as dissolved inorganic carbon. The core process uses bipolar electrodialysis (BPED) to process incoming seawater into aqueous acid and alkaline seawater.

Challenges and opportunities for marine carbon dioxide removal (mCDR)
Marine carbon dioxide removal (mCDR) refers to the techniques and technologies designed to increase the amount of carbon dioxide the ocean already captures and stores naturally through ecological and physical processes. As such, the deployment of mCDR could contribute to achieving global climate goals.Victor Brun +7 more

Advancing Monitoring Reporting and Verification for marine Carbon Dioxide Removal
Carbon dioxide removal (CDR) is becoming increasingly relevant as a complement to rapid and sustained greenhouse gas emission reductions in overshoot pathways and pathways that limit warming to 1.5–2°C. Marine CDR (mCDR) could contribute by enhancing ocean uptake and storage of carbon, but only if Monitoring, Reporting, and Verification (MRV) can ...Helene Muri +13 more

Hydrogen Gas Production for Marine Carbon Dioxide Removal
Negative emissions technologies have been developed to remove previously emitted carbon dioxide (CO2) from the atmosphere. Electrochemical ocean alkalinity enhancement has emerged as a promising approach because it can simultaneously reduce atmospheric CO2 concentrations and mitigate ocean acidification; however, its scalability is currently ...openaire +1 more source
Governance of marine carbon dioxide removal - gaps, challenges and pathways
Deliberate ocean-based interventions for the removal and storage of additional carbon dioxide from the atmosphere increasingly find consideration in science and policy. Such marine carbon dioxide removal (mCDR) approaches may counterbalance residual emissions and thereby support the achievement of global climate goals set by the Paris Agreement.Lina Roeschel, Barbara Neumann

Mechanistic evaluation of benthic carbon sequestration as a marine carbon dioxide removal strategy
Biotic ocean-based carbon dioxide removal (CDR) methods rely on various mechanisms to sink organic carbon to ocean depths, ultimately relying on seafloor burial to trap carbon. However, its long-term efficacy and environmental impacts remain uncertain, and systematic evaluation of underlying controls is warranted before large-scale deployment.Subhadeep Rakshit +2 more

A human rights-based approach to marine carbon dioxide removal governance
SSRN Electronic JournalSince the 2015 adoption of the Paris Agreement, research into marine carbon dioxide removal (mCDR), particularly technological mCDR, has received increased attention. Several research institutions and start-up companies are conducting field research, including tapping into the voluntary carbon markets.

Marine Carbon Dioxide Removal: Getting Evidence for Decision Making This Decade
The most recent Emissions Gap Report from the United Nations indicates that the world is on a path towards between 2.5-3.0°C of warming, far from the stated goals of the Paris Agreement of limiting warming to 1.5°C. Such a path poses grave risks to climate stability, biodiversity, and human flourishing on this planet.David Koweek +5 more
