  • Techno-economic analysis of an Autonomous Power system integrating hydrogen technology as energy storage medium
    Renewable Energy, 2011
    Co-Authors: George Tzamalis, E I Zoulias, Emmanuel Stamatakis, E. Varkaraki, Evripidis Lois, Fanourios Zannikos

    Abstract:

    Two different options for the Autonomous Power supply of rural or/and remote buildings are examined in this study. The first one involves a PV – diesel based Power system, while the second one integrates RES and hydrogen technologies for the development of a self – sustained Power system. The main objective is the replacement of the diesel generator and a comparison between these two options for Autonomous Power supply. Model simulations of the two Power systems before and after the replacement, an optimization of the component sizes and a techno – economic analysis have been performed for the purpose of this study. A sensitivity analysis taking into account future cost scenarios for hydrogen technologies is also presented. The results clearly show that the Cost of Energy Produced (COE) from the PV – hydrogen technologies Power system is extremely higher than the PV – diesel Power system. However, the adopted PV – hydrogen technologies Power system reduces to zero the Green – House Gas (GHG) emissions. Moreover, the sensitivity analysis indicates that COE for the latter system can be further reduced by approximately 50% compared to its initial value. This could be achieved by reducing critical COE’s parameters, such as PEM electrolyser and fuel cell capital costs. Hence, a possible reduction on the capital costs of hydrogen energy equipment in combination with emissions reduction mentioned above could make hydrogen – based Power systems more competitive.

  • Market Potential of Hydrogen-based Autonomous Power Systems
    Hydrogen-based Autonomous Power Systems, 2008
    Co-Authors: E I Zoulias

    Abstract:

    The market potential for the introduction of hydrogen-based Autonomous Power systems is analysed in this chapter. It is estimated that in the world over two billion people do not have access to a reliable electricity network. Moreover in Africa, only a 10% of urban households have an electricity supply. Even in Europe around 300,000 houses, mainly located in isolated or remote areas, such as the islands and mountains, are not interconnected to the main electricity grid. These households are currently electrified through: i) fossil-fuel-based generators facing problems with onsite fuel availability, noise and emissions, ii) renewable-energy-based systems facing problems when the natural resource (sun, wind, etc.) is not available. These disadvantages can be eliminated through the introduction of hydrogen technologies as demonstrated by Agbossou et al. (2001); therefore the market potential for hydrogen technologies in Autonomous Power systems is theoretically huge.
