CO2 EOR and Storage in Oil Reservoirs — CO2 injection into tertiary oil reservoirs has been widely accepted as an effective technique for enhanced oil recovery (EOR), and has been used by the oil industry for over 40 years. Concerns over greenhouse gas emissions are leading to the investigation and realisation of its potential as a carbon storage method in recent years. With the right reservoir...

About 20% power output penalties will be incurred for implementing CO2 capture from power plant. This loss can be partially compensated by flexible operation of capture plant. However, daily large variations of liquid and gas flows may cause operation problems to packed columns. Control schemes were proposed to improve the flexibility of power output without causing substantial hydraulic distur...

Discovery of new adsorbent materials with a high CO2 working capacity could help reduce CO2 emissions from newly commissioned power plants using precombustion carbon capture. High-throughput computational screening efforts can accelerate the discovery of new adsorbents but sometimes require significant computational resources to explore the large space of possible materials. We report the in si...

Here we found that CO(2) has high solubility in low-cost hydrocarbon surfactant liquids.

As policy makers look for strategies to reduce greenhouse gas emissions, they need to understand what options are available and under what conditions these technologies could be economically competitive. This paper explores the economics of carbon capture and sequestration technologies using the MIT Emissions Prediction and Policy Analysis (EPPA) model. We model two of the most promising carbon...

Carbon dioxide (CO2) is a greenhouse gas that is customarily released to the environment during the usage of fossil fuels, including electric power generation. With the projected increase in consumption and demand for fossil fuels, CO2 emissions will correspondingly increase in the absence of any capture/sequestration strategy. In view that CO2 is a greenhouse gas with the potential to contribu...

While carbon capture and storage (CCS) is increasingly recognised as technologically possible, recent evidence from deep-sea CCS activities suggests that leakage from reservoirs may result in highly CO2 impacted biological communities. In contrast, shallow marine waters have higher primary productivity which may partially mitigate this leakage. We used natural CO2 seeps in shallow marine waters...

The CO2 capturing and sequestration are of importance in environmental science. Understanding of the CO2-interactions with various functional molecules including multi-N-containing superbases and heteroaromatic ring systems is essential for designing novel materials to effectively capture the CO2 gas. These interactions are investigated using density functional theory (DFT) with dispersion corr...
