Carbon capture and storage (CCS), when applied to biomass cofiring systems, can remove atmospheric CO2 since the CO2 that is consumed by the biomass during growth is not released back into the atmosphere. Biomass cofiring can also potentially contribute to meeting renewable portfolio standards...

The main drawbacks of developing carbon adsorbents from pine sawdust, an abundant biomass feedstock, are the low carbon yield of the process and the poor mechanical properties of the resulting carbons. In an attempt to overcome these limitations, the effect of the addition of coal tar pitch was...

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...

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...

Biomass has great potential as a clean, renewable feedstock for producing modern energy carriers. This paper focuses on the process of biomass gasification, where the synthesis gas may subsequently be used for the production of electricity, fuels and chemicals. The gasifier is one of the...

An advanced exergy analysis is reported for a recently developed configuration of an externally-fired combined-cycle power plant integrated with biomass gasification. The results identify the potential for improvement of the overall system considering interactions among the components. It is...

Renewable energy sources can be a good substitute of the fossil fuels which are being terminated fast. Nowadays biomass and biofuels are considered because of their environment friendly characteristics and their ability of supplying much more energy. An alternative means to select the most...

The paper presents the results of exergy analysis for a biomass-to-synthetic natural gas (SNG) conversion process. The presented study is based on wood gasification, which is analysed for different gasification conditions like temperature and/or pressure. The analysed temperature was varied in...

Biomass can be converted thermo- and bio-chemically to solid, liquid and gaseous biofuels. In this paper, energy, exergy and exergoeconomic analyses are applied to a biomass integrated post-firing combined-cycle power plant. The energy and exergy efficiencies of the cycle are found to be...
