Environmental, technological, and economic analysis of supercritical coal-fired power system.

Developing countries primarily rely on fossil-based energy sources to meet their energy demands. The use of fossil fuels has several adverse environmental repercussions that damage the biosphere both directly and indirectly. Among fossil fuels, coal brings about the heaviest environmental externalities, yet its abundance makes its use widespread, particular in countries having significant power generation deficits, such as Pakistan.

Overview of environmental and economic viability of activated carbons derived from waste biomass for adsorptive water treatment applications.

In adsorptive water treatment applications, the exploration of waste-derived activated carbon (AC) has gained substantial attention in scientific research. The use of waste materials as precursors for AC has gained attention due to its economic viability and potential to reduce the consumption of non-renewable resources. However, there is a lack of comprehensive literature regarding the costs and environmental impacts associated with the waste-based AC production and application.

Underground geological sequestration of carbon dioxide (CO) and its effect on possible enhanced gas and oil recovery in a fractured reservoir of Eastern Potwar Basin, Pakistan.

Due to concerns over rising emissions of carbon dioxide (CO) from fossil fuel utilization, there has been a strong emphasis on the development of a safe, economical, practical method of carbon capture utilization and storage (CCUS). One way to reduce these CO emissions is underground geological sequestration in depleted oil fields or exhausted reservoirs. CO injection into oil reservoirs is an established technology, these reservoirs not only offer the potential for high storage of CO but this process could also target a large amount of oil and gas recovery through a technique called enhanced oil recovery (EOR).
