Webinar: Report Release and Public Briefing – A Research Strategy for Ocean CDR and Sequestration

Wednesday, December 8, 2021, 11:00 AM-12:00 PM ET 

The Committee on A Research Strategy for Ocean Carbon Dioxide Removal and Sequestration will be releasing their report entitled A Research Strategy for Ocean Carbon Dioxide Removal and Sequestration on December 8, 2021, at 11:00 AM ET. A public report release webinar will also be held from 11:00 AM to 12:00 PM ET on December 8, 2021. The report provides a path forward for research and development needed to assess the viability of promising ocean-based CDR approaches.


Are Journalists Reporting on the Highest-Impact Climate Solutions? Findings from a Survey of Environmental Journalists

Amanda C. Borth, Eryn Campbell, Sammi Munson, Shaelyn M. Patzer, William A. Yagatich, Edward Maibach IN: Journalism Practice, DOI: 10.1080/17512786.2021.2002711

The climate solutions reporting interests and practices of environmental journalists (N = 592) were analysed, paying particular attention to negative emissions technologies (NETs). It is presented that most environmental journalists are reporting on adaptation and resilience stories and renewable energy stories; additionally, over half were interested in and had recently reported on negative emissions solutions.


Shokouhi et al (2021): Physics-informed deep learning for prediction of CO2 storage site response

Parisa Shokouhi, Vikas Kumar, Sumedha Prathipati, Seyyed A. Hosseini, Clyde Lee Giles, Daniel Kifer IN: Journal of Contaminant Hydrology, Volume 241, 103835, 2021,

Here, a physics-informed deep learning method is proposed that uses deep neural networks but also incorporates flow equations to predict a carbon storage site response to CO2 injection. A 3D synthetic dataset is used to show the effectiveness of this modeling approach.


International Master on «CO2 Geological Storage»

Deadline: 17th January 2022

The call of the second edition of the International Master on CO2 Geological Storage is open. The goal of the course is to provide the participants with the scientific and technical knowledge that needs to be addressed for the successful storage of CO2 into geological formations. The programme will cover all aspects so that the students can both understand the work of all specialists who will be involved in CCS projects and further develop their own field of specialization.


Special Edition: The Law of Enhanced Weathering for Carbon Dioxide Removal

Climate discourse with Kate McKenzie (at Applepodcast)

Kate was joined by Wil Burns for a special edition of the Climate Discourse podcast to discuss the fascinating science and legal complexities of carbon removal law. They were joined by Romany Web to talk about a series of papers she published on the law of enhanced weathering for carbon dioxide removal. This is the first episode in a series highlighting some of the most important research in this area. (40 min in total)


Baumann et al. (2021): Effect of Intensity and Mode of Artificial Upwelling on Particle Flux and Carbon Export

Moritz Baumann, Jan Taucher, Allanah J. Paul, Malte Heinemann, Mari Vanharanta, Lennart T. Bach, Kristian Spilling, Joaquin Ortiz, Javier Arístegui, Nauzet Hernández-Hernández, Isabel Baños, Ulf Riebesell IN: Frontiers in Marine Science 8, 2021,1579;

Within the special Research Topic of Frontiers about Ocean Artificial Upwelling: In this study, the effect of different intensities of artificial upwelling was investigated combined with two upwelling modes (recurring additions vs. one singular addition) on POC export, sinking matter stoichiometry and remineralization depth.


Baus and Nehr (2021): Potentials and limitations of direct air capturing in the built environment

Lukas Baus, Sascha Nehr IN: Building and Environment,108629,

A novel coupling of HVAC-systems (heating, ventilation and air conditioning systems) with DAC-technology (direct air capturing technology) is proposed to separate CO2 in the exhaust air of buildings and recirculate the CO2-depleted air back into the building.
