  • options for residential building services design using fuel cell based micro chp and the potential for heat integRation
    Applied Energy, 2015
    Co-Authors: Alexandros Adam, Eduardo S. Fraga, Daniel J.l. Brett
    Abstract:

    Fuel cells offer many benefits for residential micro-cogeneRation because of their high electrical efficiency, low emissions, and low Heat-to-Power Ratio. However, the current design of fuel cell micro combined heat and power (CHP) systems for dwellings can be improved by better matching of the heat generated by the plant with the dwelling’s load profile and heat emitters.

    Abstract:

However, the current design of fuel cell micro combined heat and power (CHP) systems for dwellings can be improved by better matching of the heat generated by the plant with the dwelling's load profile and heat emitters.This paper explores the design options in building services using fuel cell micro-CHP and aims to bring the two research fields together in order to design superior integrated systems. Therefore a review of current literature on the field is performed and current available options for heat recovery from fuel cells, including the grades of heat available from different fuel cell process units are discussed. This is discussed in relation to the heat demand in a dwelling and the required temperature of the most suitable heat emitters for building services design. The paper motivates a methodology that considers all possible interconnections of plant in the design of fuel cell micro-CHP in dwellings and provides an example of how multi-objective optimisation can be used to identify promising system designs.

  • Fuel cells for micro-combined heat and power geneRation
    Energy Environmental Science, 2009
    Co-Authors: Adam Hawkes, Djl Brett, Iain Staffell, Nigel P. Brandon
    Abstract:

    Micro-combined heat and power (CHP) holds great potential for lowering energy cost and CO2 emissions in the residential housing sector. Of the various micro-CHP technologies, fuel cells, and in particular solid oxide fuel cells, show great promise due to their high electrical efficiency and resulting low Heat-to-Power Ratio that is better suited to residential applications. However, fuel cells are still under development and the capital cost of units available today remains high. This paper looks at the technological aspects and operating modes of fuel cells relevant to micro-CHP as well as examining the state of commercial development, life cycle issues and the techno-economics of fuel cells for micro-CHP at the residential scale.

  • solid oxide fuel cell micro combined heat and power system operating strategy options for provision of residential space and water heating
    Journal of Power Sources, 2007
    Co-Authors: Adam Hawkes, P Aguiar, B Croxford, Matthew Leach, Claire S Adjiman, N P Brandon
    Abstract:

    Solid oxide fuel cell (SOFC) based micro combined heat and power (micro-CHP) systems exhibit fundamentally different characteristics from other common micro-CHP technologies. Of particular relevance to this article is that they have a low Heat-to-Power Ratio and may benefit from avoidance of thermal cycling. Existing patterns of residential heat demand in the UK, often characterised by morning and evening heating periods, do not necessarily complement the characteristics of SOFC based micro-CHP in an economic and technical sense because of difficulties in responding to large rapid heat demands (low Heat-to-Power Ratio) and preference for continuous opeRation (avoidance of thermal cycling). In order to investigate modes of heat delivery that complement SOFC based micro-CHP a number of different heat demand profiles for a typical UK residential dwelling are considered along with a detailed model of SOFC based micro-CHP technical characteristics. Economic and environmental outcomes are modelled for each heat demand profile. A thermal energy store is then added to the analysis and comment is made on changes in economic and environmental parameters, and on the constraints of this option. We find that SOFC-based micro-CHP is best suited to slow space heating demands, where the heating system is on constantly during virtually all of the winter period. Thermal energy storage is less useful where heat demands are slow, but is better suited to cases where decoupling of heat demand and heat supply can result in efficiencies.
