A flexible CO<sub>2</sub> capture system for backup power plants using Ca(OH)<sub>2</sub>/CaCO<sub>3</sub> solid storage
نویسندگان
چکیده
A flexible CO 2 capture system is integrated within natural gas backup power plants. The use of Ca-storage allows decoupling the and sorbent regeneration steps, thus minimizing penalties over global efficiency costs.

The cost of carbon capture and storage for natural gas combined cycle power plants.
This paper examines the cost of CO(2) capture and storage (CCS) for natural gas combined cycle (NGCC) power plants. Existing studies employ a broad range of assumptions and lack a consistent costing method. This study takes a more systematic approach to analyze plants with an amine-based postcombustion CCS system with 90% CO(2) capture. We employ sensitivity analyses together with a probabilist...
متن کاملUnderstanding the Cost of Co2 Capture and Storage for Fossil Fuel Power Plants
As part of the USDOE’s Carbon Sequestration Program, we have developed an integrated modeling framework to evaluate the performance and costs of alternative CO2 capture and storage technologies for fossil-fueled power plants, in the context of multi-pollutant control requirements. This model (called the IECM-CS) allows for explicit characterization of the uncertainty or variability in any or al...
متن کاملPower consumption in enterprise-scale backup storage systems
Power consumption has become an important factor in modern storage system design. Power efficiency is particularly beneficial in disk-based backup systems that store mostly cold data, have significant idle periods, and must compete with the operational costs of tape-based backup. There are no prior published studies on power consumption in these systems, leaving researchers and practitioners to...
متن کاملNSBS: Design of a Network Storage Backup System
The first layer of defense against data loss is the backup data. This paper implements an agent-based network backup system used the backup, server-storage and server-backup agent these tripartite construction, and the snapshot and hierarchical index are used in the NSBS. It realizes the control command and data flow separation, balances the system load, thereby improving efficiency of the syst...
متن کاملIntegration of a Ca looping system for CO2 capture in existing power plants
This work analyses a Ca looping system that uses CaO as regenerable sorbent to capture CO2 from the flue gases generated in power plants. The CO2 is captured by CaO in a CFB carbonator while coal oxycombustion provides the energy required to regenerate the sorbent. Part of the energy introduced into the calciner can be transferred to a new supercritical steam cycle to generate additional power....
