In this study, we estimate and analyze the CO2 mitigation costs of large-scale biomass-fired cogeneration technologies with CO2 capture and storage. The CO2 mitigation cost indicates the minimum economic incentive required (e.g. in the form of a carbon tax) to make the cost of a less carbon...

Fossil fuels presently cater to majority of energy demand of the world. However, due to the climate change problem capture of CO2 emitted from the use of fossil fuels is emerging as a necessity. Alternately, developing technology with CO2 neutral fuels may reduce green house gas emission....

CO2 sorption capacities and physical properties of the MgO-based sorbent, and the effect of steam during the sorbent regeneration were studied. Four MgO-based dry regenerable sorbents (P-A ∼ D) were prepared by spray drying method for the application to pre-combustion CO2 capture. Physical...

This paper investigates the impact of combining CO2 capture and storage with alternative systems for biomass-based combined heat and power production (CHP) in Kraft pulp and paper mills. We compare heat, power, and CO2 balances of systems with alternative configurations of the CHP and...

Free piston Stirling cooler (FPSC) is a promising alternative for the conventional coolers and has been applied to various fields. In the previous research, a novel cryogenic CO2 capture system based on FPSCs has been exploited. In order to enhance the cryogenic CO2 capture efficiency, the...

In this study, an indirect forced convection solar drying system was tested for drying of palm oil fronds. The drying of 100 kg of palm oil fronds via solar drying system reduced the moisture content from 60% (w.b) to 10% (w.b) in 22 h (3 d of drying). During the drying process, the daily...

The limitations in the world sources of energy are being mitigated by the exploitation of renewable forms and by increases in the efficiency of energy utilization. Exergy analysis is a useful method for the design, evaluation, and improvement of energy systems, that uses conservation of mass and...

An exergy analysis, which only considers the unavoidable exergy destruction, is conducted for single, double, triple and half effect Water–Lithium bromide absorption cycles. Thus, the obtained performances represent the maximum achievable performance under the given operation conditions.

Biofuels are widely seen as substitutes for fossil fuels to offset the imminent decline of oil production and to mitigate the emergent increase in GHG emissions. This view is, however, based on too simple an analysis, focusing on only one piece in the whole mosaic of the complex biofuel...

The energy and exergy flow for a space heating systems of a typical residential building of natural ventilation system with different heat generation plants have been modeled and compared. The aim of this comparison is to demonstrate which system leads to an efficient conversion and supply of...
