Johansson et al. (2022): Envisioning sustainable carbon sequestration in Swedish farmland

Emma Li Johansson, Sara Brogaard, Lova Brodin IN: Environmental Science & Policy Vol.135, pp. 16-25,

The overall aim of this research is to imagine Swedish farms as carbon sinks rather than sources, and how to re-design the current farm- and food system to also address other social, economic, and environmental sustainability challenges. This paper is the outcome of two visioning workshops together with participants in an ongoing initiative called Swedish Carbon Sequestration [Svensk Kolinlagring].


Land-building marsh plants are champions of CO2 capture

by Radboud University Nijmegen on

In a study published today in the journal Science, a team of researchers from the Netherlands, U.S. and Germany shows that salt and freshwater wetlands capture and store huge amounts of CO2 through the plants that build these landscapes. (Temmink et al., 2022 „Recovering wetland biogeomorphic feedbacks to restore the world’s biotic carbon hotspots“).


Sweet spots in the sea: Mountains of sugar under seagrass meadows


„Seagrasses … are one of the most efficient sinks of carbon dioxide on Earth. A team of scientists of the Max Planck Institute for Marine Microbiology, (Germany) now reports in the journal Nature Ecology & Evolution that seagrasses release large amounts of sugar, largely in the form of sucrose, into their soils…The scientists found that seagrasses excrete phenolic compounds, and these deter most microorganisms from degrading the sucrose. This ensures that the sucrose remains buried underneath the meadows and cannot be converted into CO2 and returned to the ocean and atmosphere.“


Lundberg & Fridahl (2022): The missing piece in policy for carbon dioxide removal: reverse auctions as an interim solution

Liv Lundberg & Mathias Fridahl IN: Discover Energy 2, 3 (2022).

In this Perspectives article, the authors provide an insight into the current status of BECCS and CDR policy based on interviews with key policy makers and experts. They also provide a special insight into Sweden’s development of interim policy that takes the form of a reverse auction.


Assessing global macroalgal carbon dioxide removal potential using a high-resolution ocean biogeochemistry model

Manon Berger, Laurent Bopp, David T. Ho, Lester Kwiatkowski IN: EGU General Assembly 2022, Vienna, Austria, 23–27 May 2022, EGU22-4699,, 2022

…to be discussed at the EGU conference (Vienna, Austria & Online, 23–27 May 2022): „Here we simulate idealized global deployment of macroalgae-based CDR using the NEMO-PISCESv2 ocean biogeochemical model at high spatial resolution (0.25° nominal horizontal resolution). Macroalgae growth is confined to the upper 100m of the water column in Exclusive Economic Zones (EEZ) free of sea ice and with an appropriate nitrate/phosphate regime. Although the loss of dissolved inorganic carbon (DIC) through macroalgal growth enhances the flux of atmospheric carbon into the ocean, this increase in carbon uptake is less than the rate of macroalgal production.“


Ahlström et al. (2022): Sustainable Aviation Fuels – Options for Negative Emissions and High Carbon Efficiency

Johan M. Ahlström, Yawer Jafri, Elisabeth Wetterlund, Erik Furusjö; 59 pp. available at SSRN,

The authors investigate seven different pathways for producing aviation biofuels coupled with either bio-energy carbon capture and storage (BECCS), or bio-energy carbon capture and utilization (BECCU). Both options allow for increased efficiency regarding utilization of feedstock carbon. The analysis uses process-level carbon- and energy balances, with carbon efficiency, climate impact and LCOP as primary performance indicators.


Zeng & Hausmann (2022): Wood Vault: remove atmospheric CO2 with trees, store wood for carbon sequestration for now and as biomass, bioenergy and carbon reserve for the future

Ning Zeng, Henry Hausmann IN: Carbon Balance Manage 17, 2 (2022),

Wood harvesting and storage (WHS) is a hybrid Nature-Engineering combination method to combat climate change by harvesting wood sustainably and storing it semi-permanently for carbon sequestration. To date, the technology has only been purposefully tested in small-scale demonstration projects. This study aims to develop a concrete way to carry out WHS at large-scale.


Report: Technology Readiness Assessment, Costs and Limitations of five shortlisted NETs

Kenneth Möllersten, Raza Naqvi, Mälardalen University, Report of the NET-RAPIDO Project: Negative emission technologies: readiness assessment, policy instrument design, options for governance and dialogue, 77 pp.

This report presents an in-depth technology readiness, cost assessment and an analysis of practical deployment barriers for NETs along with an analysis of related knowledge gaps and research needs. The selected NETs are (i) bioenergy with carbon capture and storage (BECCS); (ii) direct air capture and storage (DACCS); (iii) large-scale afforestation and reforestation; (iv) soil carbon sequestration; (v) Biochar as soil additive; (vi) Enhanced Weathering; (vii) Accelerated Mineralization; (viii) Ocean fertilization.
