A Comparative Techno-economic Analysis of Hydrogen Production Processes from Locally Available Resources in Nigeria
Abstract: In this work we report result of techno-economic analyses of three hydrogen production pathways - Steam Methane Reforming (SMR), SMR with Carbon Capture (SMR+CC) and Proton Exchange Membrane electrolysis (PEM) – using integrated process-cost simulation-estimation methodologies. Process modeling and simulation is performed with Aspen Hysys® and Aspen Plus® (V10). Cost modeling and estimation is based on full lifecycle cost of production using the Levelized Cost of Hydrogen (LCOH) approach. Feedstock …

Seasonal Variation in the Weibull Parameters from In Situ Measurements and Model: A Case Study in the Bay of Bengal
Abstract: Seasonal variation of wind speed (U10) and its distribution are essential for the design of wind energy converters (WEC). In this study, year-round wind speed observations from a deepwater moored buoy at a location in the Bay of Bengal are used to assess the potential for wind power generation and are used to validate the ERA5 model. Model-U10 distribution is confined to low wind speeds with high occurrence in the …

An Overview of Hybrid Renewable Energy Systems
Abstract: Long-term evaluation and analysis of several factors should be done to propose a full-phase power generation system based on renewable energy sources. An accurate assessment of the potentially available resources should be done like measuring solar irradiation, wind speed, etc. We are designing a hybrid system where hybridization methods entirely consist of renewable energy sources—specifically solar photovoltaic (PV), wind, and gravity systems. Wind and solar are among the popular renewable …
