Накратко на български

Наноматериали от определени скали и кариерни отпадъци се тестват за улавяне на въглероден диоксид и използване в строителството на строителни смеси. Това помага за намаляване на вредните емисии в атмосферата и подобряване на свойствата на строителните материали.

Carbon dioxide storage in nanomaterials based on ophiolitic rocks and utilization of the end-product carbonates in the building industry

The extensive use of fossil fuels has led to a substantial increase of anthropogenic CO2 emissions, which are considered to be a main cause for the observed global warming. A popular proposed solution to this crucial problem is carbon capture and storage (CCS). The CO2NOR project investigated an innovative method for ex situ mineral carbonation that ensures the safe storage of CO2. This method includes the development of novel nanomaterials with high CO2-storage capacity via the ball milling process, based on low-cost ultramafic and mafic rocks from the Troodos ophiolite. The overall objectives of the CO2NOR Project are summarized as follows: • Development of novel nanomaterials via the ball milling process based on ophiolitic rocks/quarry wastes. • Investigation of the CO2 adsorption properties of different nanoscale rocks. • Study of the potential role of enhanced weathering of nanoscale ophiolitic rocks in seawater as a viable carbon sequestration approach. • Investigation of the role of milled quarry wastes as nano-additives in the building industry. The main conclusions of the CO2NOR Project are summarized as follows: • Ball milling results in a substantial increase of specific surface area and CO2 uptake of mafic/ultramafic rocks and waste materials. • Different optimum ball milling parameters were determined for each rock material, with the dunite having the highest CO2 uptake. • The enhanced weathering of ball-milled peridotites in seawater can induce the drawdown of CO2 directly from the atmosphere. • The use of milled mafic quarry wastes as additives in the building industry results in the production of mortars with enhanced engineering properties.

Цел на проекта

Anthropogenic activities have increased atmospheric CO2 concentrations, which are considered to be the main cause of global warming. The EU has set itself targets for reducing its greenhouse gas emissions progressively up to 2050. A popular proposed solution to this crucial problem is carbon capture and storage (CCS). Ophiolitic rocks are considered among the most promising lithotypes for CO2 storage due to their high reactivity and many exposures in the world. In this proposal, an innovative and sustainable method for ex situ mineral carbonation will be suggested that will ensure the safe storage of CO2. This method includes the creation of novel nanomaterials via the ball milling process, based on low-cost ultramafic and mafic rocks from the Troodos ophiolite (Cyprus), which is considered as the most complete ophiolite worldwide. Although numerous studies have been carried out on the petrogenetic evolution of the Troodos ophiolite, a systematic work about the applicability of these rocks for CCS will be done for the first time in this study. Fines and waste material from quarries in the wider Troodos area will also be used for the development of nanomaterials. It is anticipated that ball milling will accelerate the kinetics of rock-fluid reactions during the carbonation procedure. Hence, carbonate minerals, which are stable over geological timescales, will provide a safe long term CCS solution. Additives will also be tested in the nanomaterials in an attempt to increase their CO2-storage capacity. The proposal also involves applied research in the form of exploitation of the end-product carbonates in the building industry. The successful outcome of this project will be based on the researcher’s extensive experience in the study of mafic and ultramafic ophiolitic rocks and mineral carbonation, as well as on supervisor’s expertise in the fields of nanomaterials and CCS.
