  • A Vanadium-Redox-Flow-Battery Model for Evaluation of Distributed Storage Implementation in Residential Energy Systems
    IEEE Transactions on Energy Conversion, 2015
    Co-Authors: Riccardo D'agostino, Lars Baumann, Alfonso Damiano, Ekkehard Boggasch
    Abstract:

    A vanadium-redox-flow-battery (VRFB) model suitable for annual energy feasibility analyses of distributed storage implementation is presented in this paper. The validation of the proposed 6-kW/20-kWh VRFB semiempirical model, which takes into account Auxiliary Power Consumption and operational aspects such as startup and standby behavior, is reported. The comparison between the simulation and the experimental results shows a good matching, quantified by the maximum root-mean-square deviation of the stack energy equal to 1.57% and 2.47% during charge and discharge, respectively. Moreover, the VRFB model is used in an application model of a residential building including a photovoltaic system and heat pump. Based on variation of control parameters, the energy efficiency for the proposed application has been maximized. Finally, a comparison with a scaled VRFB model (3 kW/10 kWh) is discussed with respect to the increase of the VRFB utilization and overall energy efficiency, confirming the effectiveness of the proposed model for distributed energy storage sizing and management in residential systems.

  • Coal based Power plants using oxy-combustion for CO2 capture: Pressurized coal combustion to reduce capture penalty
    Applied Thermal Engineering, 2013
    Co-Authors: Rengarajan Soundararajan, Truls Gundersen
    Abstract:

    Abstract The goal of this paper is to design and study a new variation of an oxy-combustion coal based Power plant with CO2 capture. This variation employs a pressurized coal combustor that burns coal in an oxygen rich environment. The concept is compared with an atmospheric pressure oxy-combustion Power plant (baseline case). Such analyses would provide us with information regarding potential heat integration and improvement opportunities of oxy-combustion coal based Power plants. Also, this study highlights the efficiency improvement potential of the oxy-combustion technology for coal based Power plants. The Power cycle presented in this paper is a supercritical cycle that has a gross electric Power output of 774 MW for the baseline case and 792 MW for the pressurized case. The Auxiliary Power Consumption is reduced from 224 MW in the baseline case to 214 MW in the pressurized case due to the absence of air leakage into the boiler. The recovery of latent heat from the flue gases is increased due to the elevated dew point in the pressurized case. This results in a net LHV and HHV efficiency improvement of 1.7 percentage points each over the baseline case. In both the cases, over 90% of the produced CO2 is captured and compressed to 110 bar after removal of volatiles and other pollutants such as SOx and NOx.
