(2024). Multi-scale lidar measurements suggest miombo woodlands contain substantially more carbon than thought. Communications Earth & Environment, 5(1), 366.Synopsis: Miombo woodlands are vital for southern African livelihoods, biodiversity, and the global carbon cycle. Using terrestrial and airborne lidar data, this study estimated aboveground biomass with low uncertainty. Researchers found 1.71 ± 0.09 TgC stored in biomass, 1.5-2.2 times more than conventional methods. This suggests a significant underestimation of Africa's miombo woodlands' carbon stock, implying a need for revised carbon sequestration and emissions estimates, promoting better protection and restoration efforts.
Norton, H., Todd, D., & Crawford, C. (2024). Storage capacity estimates and site conditions of potential locations for offshore-wind powered carbon dioxide removal and carbon sequestration in ocean basalt. Carbon Capture Science & Technology, 13, 100231.Synopsis: Negative emission technologies are crucial to limit global warming below 2 °C. This study explores wind-powered CDR devices offshore, injecting CO2 into sub-seafloor basalt aquifers. Offshore wind sites with basalt storage potential were identified using 30 years of wind speed data. Regions near the poles showed the best wind resources. Estimated storage capacity ranges from 4,300Gt to 196,000Gt, far exceeding global NET targets. This method avoids land use competition and minimizes leakage risk compared to terrestrial storage.

Zhang, E., Li, Y., Wang, Y., Liu, D., Cong, Y., Liu, J., ... & Zheng, Q. (2024). Synergistic CO2 removal via enhanced olivine weathering and diatom growth in the ocean. Ocean-Land-Atmosphere Research.Synopsis: This study explores the synergistic CO2 removal potential of an olivine–diatom coculture system in enhancing ocean alkalinity and promoting marine carbon sequestration. Over a 6-day period, olivine dissolution was significantly higher in olivine–diatom groups compared to olivine-only groups, leading to CO2 removal efficiencies of 8.84% to 14.44% versus 5.15% to 5.49%, respectively. This approach not only increases alkalinity but also boosts diatom growth and fixed carbon content, highlighting its promise as an effective climate change mitigation strategy leveraging biological and chemical processes in the ocean.
Griffiths, I., Wang, R., Ling-Chin, J., & Roskilly, A. P. (2024). Solid oxide fuel cells with integrated direct air carbon capture: A techno-economic study. Energy Conversion and Management, 315, 118739.Synopsis: This study evaluates the feasibility of using a hydrogen-fed solid oxide fuel cell (SOFC) to power DAC, aiming to mitigate atmospheric CO2 levels. Modeling a renewable hydrogen-fed 50 MW SOFC integrated with DAC, it predicts a capacity to capture over 270 kt/year of CO2. Initial cost estimates vary widely based on renewable hydrogen prices, suggesting potential competitiveness with natural gas-fed DAC as hydrogen costs decline. By 2050, the projected cost could reach £191/tonne of CO2 captured, underscoring its potential as a sustainable DAC solution.

What Role Will Carbon Removal Play Under Article 6 of the Paris Agreement? | Institute for Responsible Carbon Removal “Although the Paris Agreement committed its signatories to limit global temperature increases and many countries have put forward net-zero climate targets, the carbon crediting rules under Article 6 of the Paris Agreement are still in their early stages of development for both emission reduction and carbon removal activities. But what will the balance of priorities be? The United Nations' primary experience with carbon crediting programs is its Clean Development Mechanism, an international offsetting program developed under the 1997 Kyoto Protocol. Not only has the Clean Development Mechanism been criticized in the academic literature for its low-quality outcomes, but its focus is almost entirely distinct from the sectors of most interest for carbon removal: it predates the contemporary interet in long-duration carbon removal pathways and only a handful of its projects involve the land sector. Meanwhile, a large number of legacy Clean Development Mechanism projects are slated for transition into the Article 6.4 mechanism, along with the potential approval of its revised carbon crediting methodologies for global use. These political priorities, along with long-standing tensions over the appropriate role of temporary carbon storage in carbon markets, help illuminate issues that eluded consensus last year at COP28 in Dubai and are likely to be part of upcoming COP29 negotiations in Baku.”
