Hybrid Event: Achieving climate neutrality and the Paris Agreement goals: Opportunities for ocean-based methods of carbon dioxide removal (CDR)

Tuesday 25 October 2022, 12:00 – 14:00 CEST

The event is jointly organized between the EU H2020 project OceanNETs, the German research mission CDRmare, and EBCD. Co-hosts are MEP Maria da Graça Carvalho and MEP Catherine Chabaud, Co-Chairs of the ‘Ocean Governance’ Working Group of the European Parliament Intergroup on ‘Climate Change, Biodiversity and Sustainable Development‘.

This event invites Members of the European Parliament, the European Commission, member states, and other interested stakeholders, including non-governmental organizations, industry and academia, to address the previous results of OceanNETs and CDRmare, specifically looking at important background information for national, European and international political processes, agreements and regulations, such as the national Climate Protection Plan 2050, the IPCC reports, the COP27 negotiations and the European Commission’s initiative on ‘Certification of carbon removals’.


Nature-Manuscript submission: Carbon Capture and Storage

Submission deadline: 30 November 2022

Research is ongoing in all elements of CCS, including materials and chemical processes for CO2 removal, how to integrate new technologies into industry and the potential for long-term storage of carbon in geological reservoirs. This Collection brings together the latest research in carbon capture and storage. Submit the manuscript for consideration at Scientific Reports as part of this Collection. Editors are: Rouhi Farajzadeh, Qinjun Kang, Haiqing Lin, Hasmukh Patel, Jhuma Sadhukhan, Lidija Šiller.


Briefing: Sustainable carbon cycles: Promoting removal, storage and recycling

by Liselotte Jensen (European Parliamentary Research Service)

„At the end of 2022, the EU Commission plans to put forward a legislative proposal on a European framework for the certification of carbon removals, which could lead to a market for carbon removals, further incentivising measures to increase carbon sequestration and storage. Ensuring high environmental integrity and adequate monitoring and reporting frameworks is crucial, while also taking into account potential trade-offs or co-benefits of potential solutions.“

„This briefing document is prepared for, and addressed to, the Members and staff of the European Parliament as background material to assist them in their parliamentary work. The content of the document is the sole responsibility of its author(s) and any opinions expressed herein should not be taken to represent an official position of the Parliament.“


Sovacool et al. (2022): Determining our climate policy future: expert opinions about negative emissions and solar radiation management pathways

Benjamin K. Sovacool, Chad M. Baum, Sean Low IN: Mitig Adapt Strateg Glob Change 27, 58,

In this study, the authors rely on a large expert survey (N = 74) to critically examine the future potential of both negative emission options (e.g., carbon dioxide removal) and solar radiation management techniques. The authors designed a survey process that asked a pool of prominent experts questions about (i) the necessity of adopting negative emissions or solar radiation management options, (ii) the desirability of such options when ranked against each other, (iii) estimations of future efficacy in terms of temperature reductions achieved or gigatons of carbon removed, (iv) expectations about future scaling, commercialization, and deployment targets, and (v) potential risks and barriers.


Research Associate in Resources for Greenhouse Gas Removal

Deadline: 10/31/2022

The Research Centre for Carbon Solutions (RCCS) (Heriot-Watt University, Edinburgh) is seeking a postdoctoral research associate to work on greenhouse gas removal research. This post is part of a large consortium project to explore the feasibility of enhanced weathering. Particularly, the postholder will dissolution/weathering of artificial materials (e.g., cement, steel slag), their potential environmental benefits and/or impacts if used for enhanced weathering, and their potential to contribute to UK Net-Zero strategies. The appointment will be at Research Associate level, Grade 7, Salary: £34,308 – £35,333, fixed term opportunity for 24 months


Public Consultation of Enhanced Rock Weathering (ERW) in Soil Methodology

by; Consultation period open until 17.10.2022

„ present their first ERW carbon crediting methodology for public consultation. […] The working group has defined safeguards and quantification approaches aligned with the latest science. This methodology ensures little to no environmental impact, which is critical to increasing public acceptance of ERW. It sets strict thresholds for contaminant levels of the ground rock in accordance with the EU regulation for inorganic soil improvers and require projects to perform laboratory tests of soil samples to establish baselines. In acidic conditions, ERW has the co-benefit of restoring nutrient depleted soils.“


Midwest Regional Carbon Conversion/Utilization Procurement Grant Workshop

October 18, 2022 – 9:00 am to 4:45 pm CDT, virtually or in-person (Minneapolis)

DOE-FECM will establish a demonstration grant program within the Carbon Conversion/Utilization Program to support eligible applicants that procure commercial and industrial products derived from anthropogenic carbon oxides. Therefore, the Carbon Conversion/Utilization Program, with the assistance of the United States Energy Association (USEA), will conduct a series of workshops (both virtual and in-person) with relevant stakeholders, e.g., product manufacturers, eligible entities, or their representative national organizations (e.g., United States Conference of Mayors, etc.) to solicit input and ideas on challenges and opportunities for a potential grant program. USEA invites to the upcoming regional workshops, the last of which will be held in the Twin Cities in Minnesota. 


Brandl et al. (2022): A century of re-exploring CO2 capture solvents

Patrick Brandl, Mai Bui, Jason P. Hallett, Niall Mac Dowell IN: International Journal of Greenhouse Gas Control 120, 103771,

In this contribution, the authors present a thought-experiment that uses a hypothetical solvent to identify the limit of available cost reductions to 65% over current performance benchmarks, reaching a cost limit of $26/tonCO2 for gas-power.


Why $100 per ton is the carbon removal industry’s holy grail

by Michelle Ma on

„Carbon dioxide removal service buyers and sellers are focused on one metric: $100 per ton. It’s one of Frontier’s stated criteria that the fund uses to evaluate its advance purchases. In a survey of the long-duration carbon removal community, CarbonPlan found that stakeholders are focused on the $100 benchmark. The Department of Energy even announced that it would be investing in carbon removal research to bring the cost of the technology down to $100 per ton.“


Scown (2022): Prospects for carbon-negative biomanufacturing

Corinne D. Scown IN: Trends in Biotechnology, ISSN 0167-7799,

This review explores the magnitude of carbon removal achievable through biomanufacturing and discusses the likely fate of carbon in a range of target molecules. Solvents, cleaning agents, or food and pharmaceutical additives will likely re-release their carbon as CO2 at the end of their functional lives, while carbon incorporated into non-compostable polymers can result in long-term sequestration.
