Scaling carbon removal requires a portfolio approach

Philip Moss & Ben Rubin, on thehill.com; 03/18/23 12:30 PM ET

„A growing number of governments and corporations are responding to this climate challenge by investing in solutions that remove carbon emissions from the atmosphere. Many on the market are taking a portfolio approach, investing in a wide range of promising solutions and minimizing risk. To continue encouraging innovation and a menu of proven options, it’s imperative to keep a level playing field and avoid picking winners and losers.“

Capturing Carbon Isn’t Enough. We Need to Remove It.

by Lara Williams (Bloomberg) on washingtonpost.com; March 18, 2023 at 8:03 a.m. EDT

„The US’s Inflation Reduction Act (IRA) and Bipartisan Infrastructure Act have together provided billions to support the development and deployment of carbon-removal approaches, including $3.5 billion for four DAC hubs alone. While the UK can’t compete in terms of cash, it could leverage its position as a world leader in research to nurture climate startups. Without more funding and regulatory support, UK climate innovations risk getting stuck in the so-called valley of death, a period in which a significant increase in funding is required to make the transition from academic research to commercialization. With the US offerings already tempting some startups to cross the pond, including Switzerland’s Climeworks AG, the UK could really miss out on the potential to create even more green jobs, level up its regional hubs and become an exporter of cutting-edge climate technology.“

What ocean for tomorrow? Marine ecosystems in a changing climate – Insights from the IPCC’s Sixth Assessment Report

on ocean-climate.org, March 20

„Today, the Intergovernmental Panel on Climate Change (IPCC) release the Sixth Assessment Report (AR6) Synthesis Report. Promoting a wide and better understanding of these phenomena, as well as the inclusion of marine ecosystems in all climate and environmental policies, the Ocean & Climate Platform (OCP) publishes this article. Drawing from the AR6, the OCP convened a community of scientists and science mediation experts to produce accessible content on the role of marine ecosystems, the impacts of human activities and climate change, and the solutions they could offer. As such, this publication contributes to strengthening knowledge assimilation and informed action, in line with the goal of effectively protecting marine ecosystems.“

Sands et al. (2023): Perspective – The Growing Potential of Antarctic Blue Carbon

Chester J. Sands, Nadescha Zwerschke, Narissa Bax, David K.A. Barnes, Camille Moreau, Rachel Downey, Bernabé Moreno, Christoph Held, Maria Paulsen IN: Frontiers in Ocean Observing: Emerging Technologies for Understanding and Managing a Changing Ocean. [Eds.] E.S. Kappel, V. Cullen, M.J. Costello, L. Galgani, C. Gordó-Vilaseca, A. Govindarajan, S. Kouhi, C. Lavin, L. McCartin, J.D. Müller, B. Pirenne, T. Tanhua, Q. Zhao, S. Zhao; Oceanography 36 (Supplement 1), https://doi.org/10.5670/oceanog.2023.s1.5

In this perspective article, the Antarctic blue carbon is discussed: Antarctic blue carbon potential is one of many understudied carbon removal pathways. Full understanding of the geography and magnitude of carbon sequestration is required to enable placing an appropriate value on the
services nature can provide if adequately safeguarded. Investment in gaining this knowledge (to help prioritize protection and meaningful monitoring) would cost only a fraction of that for commercial carbon capture and sequestration, and a fraction of the ultimate value of the carbon sequestered on the Antarctic continental shelf.

Waite et al. (2023): Perspective Net Zero – Actions for an Ocean-Climate Solution

Anya Waite, Mike Smit, Eric Siegel, Greg Hanna , Sara Leslie IN: Frontiers in Ocean Observing: Emerging Technologies for Understanding and Managing a Changing Ocean. [Eds.] E.S. Kappel, V. Cullen, M.J. Costello, L. Galgani, C. Gordó-Vilaseca, A. Govindarajan, S. Kouhi, C. Lavin, L. McCartin, J.D. Müller, B. Pirenne, T. Tanhua, Q. Zhao, S. Zhao; Oceanography 36 (Supplement 1), https://doi.org/10.5670/oceanog.2023.s1.6

A vision is needed for development of the world’s first international climate observatory that would record carbon and heat fluxes from the seafloor to the atmosphere. This initiative would require leading nations to communicate, pool, and coordinate their already substantial investments in observing infrastructure, and their expertise in the areas of science, policy, and innovation, to create information streams that would benefit all participants involved, along with the rest of the world.

Bresnanhan et al. (2023): A Low-Cost Carbon Dioxide Monitoring System for Coastal and Estuarine Sensor Networks

Philip J. Bresnahan, Elizabeth Farquhar, Daniel Portelli, Michael Tydings, Taylor Wirth, Todd Martz IN: Frontiers in Ocean Observing: Emerging Technologies for Understanding and Managing a Changing Ocean. [Eds.] E.S. Kappel, V. Cullen, M.J. Costello, L. Galgani, C. Gordó-Vilaseca, A. Govindarajan, S. Kouhi, C. Lavin, L. McCartin, J.D. Müller, B. Pirenne, T. Tanhua, Q. Zhao, S. Zhao; Oceanography 36 (Supplement 1), https://doi.org/10.5670/oceanog.2023.s1.4

As the interest in marine or ocean-based carbon dioxide removal (mCDR) increases, so does the need for more spatially resolved measurement, reporting, and verification (MRV) of the CO2 sequestered (and for understanding the impacts of these environmental manipulation experiments). Here the authors describe our efforts toward a low-cost CO2 flux or ∆pCO2 (the difference between air and water partial pressure of CO2) monitoring system intended for use in distributed sensor arrays in coastal, estuarine, and blue carbon research and in mCDR approaches.

Gracia et al. (2023): Assessing Changes in Marine Biogeochemical Processes Leading to Carbon Dioxide Removal with Autonomous Underwater Vehicles

Catherine Garcia, Benedetto Barone, Sara Ferrón, David Karl IN: Frontiers in Ocean Observing: Emerging Technologies for Understanding and Managing a Changing Ocean. [Eds.] E.S. Kappel, V. Cullen, M.J. Costello, L. Galgani, C. Gordó-Vilaseca, A. Govindarajan, S. Kouhi, C. Lavin, L. McCartin, J.D. Müller, B. Pirenne, T. Tanhua, Q. Zhao, S. Zhao; Oceanography 36 (Supplement 1), https://doi.org/10.5670/oceanog.2023.s1.3

Autonomous underwater vehicles (Seagliders) have been deployed from ships in the vicinity of Station ALOHA for more than 16 missions since 2008. Seagliders can be used to characterize the variability of primary production, respiration, and particle dynamics to illuminate their relationship with high-productivity events. These events can serve as a framework for monitoring the short-term evolution of a water patch following “boom” and “bust” phases similar to that predicted during open ocean CDR experiments.

What is the IPCC AR6 synthesis report and why does it matter?

by Fiona Harvey, on The Guardian.com, Sun 19 Mar 2023 11.00 GMT

„Summary report by world’s leading climate scientists sets out actions to stave off climate breakdown.[…] What should governments do? Reduce emissions sharply and give up fossil fuels, through investments in renewable energy and other low-carbon technologies, increase energy efficiency, rethink agriculture and restore forests and degraded natural landscapes. It may also be necessary to develop technologies that suck carbon dioxide from the air, called “direct air capture”, or explore other means of “climate repair”.“

EU setzt weltweit erstes verbindliches Ziel für unterirdische CO2-Speicherkapazität

Frédéric Simon, EURACTIV.com; 17. März 2023

„Die EU-Kommission hat angekündigt, bis 2030 eine Kapazität für die unterirdische langfristige Lagerung von 50 Millionen Tonnen CO2 zu schaffen. Damit setzt sie die Öl- und Gasindustrie unter Druck, die seit Jahren ohne Taten davon sprechen. Die Abscheidung und Speicherung von Kohlendioxid (CCS) wird im Net-Zero Industry Act der Kommission, der am Donnerstag vorgestellt wurde, als eine der Schlüsseltechnologien für die nachhaltige Entwicklung aufgeführt.“
