The electrochemical reduction of carbon dioxide is usually studied in aqueous solutions under ambient conditions. However, the main disadvantages of this method are high hydrogen evolution and low faradaic efficiencies of carbon-based products. Supercritic ...
Lakes at high altitude and latitude are typically unproductive ecosystems where external factors outweigh the relative importance of in-lake processes, making them ideal sentinels of climate change. Climate change is inducing upward vegetation shifts at hi ...
Soil incorporation of charcoal (biochar) has been suggested as practice to sequester carbon, improve soil properties and crop yields but most studies have been done in the short term. Old anthropogenic charcoal-rich soils in the Alps enable to explore the ...
Geologic carbon storage is considered to be one of the main solutions to significantly reduce CO2 emissions to the atmosphere to mitigate climate change. CO2 injection in deep geological formations entails a two-phase flow, being CO2 the non-wetting phase. ...
Northern hemisphere peatlands are substantial carbon stores. However, recent climate change and human impacts (e.g., drainage and atmospheric nutrient deposition) may trigger the emission of their stored carbon to the atmosphere. Biodiversity losses are al ...
A significant part of the cost for carbon capture and storage ( CCS) is related to the compression of captured CO2 to its supercritical state, at 150 bar and typically 99% purity. These stringent conditions may however not always be necessary for specific ...
CO2 storage in geological formation, especially in deep aquifers, is considered as a compromising technology to reduce the impact of CO2 on the greenhouse effect. Practically, large-volume of CO2 could be injected at a high rate into a system which consist ...
CO2 sequestration in deep geological formations is considered as a promising technology to reduce the impact of CO2 on the greenhouse effect. Practically, large-volume of CO2 could be injected into a system that consists of a highly porous host reservoir c ...
Carbon Capture and Storage ( CCS) is the only available technology that allows us to significantly reduce our CO2 emissions while keeping up with the ever-increasing global energy demand. Research in CCS focuses on reducing the costs of carbon capture and ...
Lignocellulosic biomass feedstocks are considered as one of the major alternative for fossil and food based transport fuel and chemicals for the reasons such as fuel/food security, depleting fossil reserves, climate change, mitigate pollution in agricultur ...
