Initial carbon storage in new tephra layers of Mt. Talang in Sumatra as affected by pioneer plants Ghent University
To date, no global data on carbon sequestration at the initial weathering phase of tephra deposits are available. To study carbon storage in the new volcanic deposit, tephra layers were reconstructed for a period of 46months. The tephra samples were collected immediately after eruption of Mount (Mt.) Talang on 12 April 2005, over portions of the Solok District in West Sumatra, Indonesia. Pot experiments were filled with and without soil ...
Strategic Responses to Imposed Innovation Projects: The Case of Carbon Capture and Storage in the Alberta Oil Sands Industry Vrije Universiteit Brussel
Today's ‘activist’ attitudes and strong power of non-market stakeholders (such as government agencies, non-governmental organizations, labor unions) have triggered the phenomenon of imposed innovation projects. These are investment projects carried out by profit-seeking firms primarily in response to the demands of influential non-market stakeholders. Such projects are supposedly instrumental to the emergence of new, socially beneficial ...
Carbon capture and storage in China : status, regulatory framework and outlook Ghent University
Nowadays China is increasingly facing strong international pressures to reduce carbon emissions, standing at the cross-road of climate change issues: how to fulfill the emission reduction goal without undermining and blocking its ambitions on sustainable economic development. Facing this situation, carbon capture and storage（CCS）can be a new weapon for China to win the battle of climate change mitigation. Based on the description and analysis on ...
Novel hexaazatrinaphthalene-based covalent triazine frameworks as high-performance platforms for efficient carbon capture and storage Ghent University
As rigid and planar aza-based heteroaromatic scaffolds, hexaazatriphenylene (HAT) derivatives exhibit significant electron-deficient properties and high pi-pi stacking tendencies, which makes them promising building blocks for the construction of supramolecular architectures and functional porous materials. In this study, the rational design and synthesis of a family of novel and nitrogen-rich hexaazatrinaphthalene-based covalent triazine ...
Potential influence of CO2 release from a carbon capture storage site on release of trace metals from marine sediment KU Leuven
One of the main risks of CCS (Carbon Capture and Storage) is CO2 leakage from a storage site. The influence of CO2 leakage on trace metals leaching from contaminated marine sediment in a potential storage area (Northern Spain) is addressed using standardized leaching tests. The influence of the pH of the leaching solution on the leachates is evaluated using deionized water, natural seawater and acidified seawater at pH = 5, 6 and 7, obtained by ...
Evaluation through column leaching tests of metal release from contaminated estuarine sediment subject to CO2 leakages from Carbon Capture and Storage sites KU Leuven
The pH change and the release of organic matter and metals from sediment, due to the potential CO(2) acidified seawater leakages from a CCS (Carbon Capture and Storage) site are presented. Column leaching test is used to simulate a scenario where a flow of acidified seawater is in contact with recent contaminated sediment. The behavior of pH, dissolved organic carbon (DOC) and metals As, Cd, Cr, Cu, Ni, Pb, Zn, with liquid to solid (L/S) ratio ...
Lianas significantly reduce aboveground and belowground carbon storage : a virtual removal experiment Ghent University
Lianas are structural parasites of trees that cause a reduction in tree growth and an increase in tree mortality. Thereby, lianas negatively impact forest carbon storage as evidenced by liana removal experiments. In this proof-of-concept study, we calibrated the Ecosystem Demography model (ED2) using 3 years of observations of net aboveground biomass (AGB) changes in control and removal plots of a liana removal experiment on Gigante Peninsula, ...
Modeling soil organic carbon storage and its dynamics in croplands of China Ghent University
Soil organic carbon (SOC) is one of the centre issues related to not only soil fertility but also environmental safety Assessing SOC dynamics in croplands has been a challenge in China for long due to the lack of appropriate methodologies and data sources As an alternative approach for studying SOC dynamics, process-based models are adopted to meet the needs In this paper, a process-based model. DeNitrification-DeComposition (DNDC). was applied ...
