Application on Solar, Wind and Hydrogen Energy - A Feasibility Review for an Optimised Hybrid Renewable Energy System

Subhashish Banerjee, Md. Nor. Musa, Dato’ IR Abu. Bakar Jaafar and Azrin Arrifin

Present status of development of the energy systems, like solar, wind and of Hydrogen use as renewable energy sources, have been examined in ascertaining the scope of their application from techno-economic viability.

Efficiency rating of different generations of PV cells with cost component and scope of their use, including practical application and economic fall outs thereby, were also spelt out from case study. Cost of PV module being shown to be the main contributor, deciding the economy of PV – based power generation scheme, the methodology of determining its total requirement could also be shown. Economy evaluation of solar PV and solar heating (solar cooker, solar pond, etc.) were also assessed stating their merits and demerits.

Different aspects on evaluation of economy for off-shore and on-shore wind energy for developing a wind farm at a particular site were assessed. The scope of availing the wind energy value /sq. m. at a concerned site for a particular wind speed (measuring it at anemometer height and converting to its value at the hub height), could also be ascertained.

Necessary study on the economy of hydrogen production by splitting water (electrolysis) was made and was noted that the OTEC (ocean thermal energy conversion system) generated electricity would be the best cost-effective method, mainly because of its prospect of earning huge royalty from its different by-products. On examination of H2-fuel cell combine as transport fuel, it could be shown that a single 100 MW OTEC can cater to 30 hydrogen refuelling stations, each with 250 vehicle movement/day.

Feasibility study on optimised hybridization of the combination of PV-wind and H2, for uninterrupted power supply with methodology on resource assessment at concerned sites, particularly for PV and wind energy with economic fall outs, could be ascertained. Grey areas of research in exploring acoustic energy is also discussed.
