| dc.description.abstract | The need for more sustainable and efficient fuel
applicable to different development sectors calls for different
strategies in energy systems pattern. This paper is aimed at
designing off-grid solar PV/biogas hybrid power system with
hydrogen storage for Maiduguri in Northern Nigeria, using
HOMER and Microsoft-Excel tools. This was based on physical
component techno-economic modelling and optimization coupled
with energy efficiency assessment and a supplementary economic
benefit evaluation of system switch over. Potential impact
assessment of the hydrogen production was also ensured. The
optimization result for the system with the maximum hydrogen
production showed energy generation of 3,014.66MWh, but was
found to be 31% less in the energy efficiency (EE) adoption. The
hydrogen production of the system being 2,768kg/yr. increased by
5%, with net present cost reduction by 39% and further
greenhouse gas emissions reduction all in favour of the energy
efficiency adoption to the system. The supplementary economic
benefits showed a realisable payback period and other potential
impacts from the saved cash in switching to the energy efficiency
adoption from the based-case standalone system. The generated
hydrogen revealed its sustainability impact in an analyses of
transport sector. These in overall being a double-target approach
could be of tremendous benefit in energy solutions. | en_US |
