The current study presents a comprehensive investigation of different energy system configurations for remote village community in India with entirely renewable electricity. Excess electricity generated by the systems has been stored using two types storage options: lithium-ion batteries and green hydrogen production through electrolysers. hybrid (HRES) have sized minimising levelised cost (LCOE). In order to identify best-performing HRES configuration, economic environmental performance indicators analysed multi-criteria decision-making method (MCDM), TOPSIS. Among evaluated configurations, system-1 photovoltaic panel (PV) size 310.24 kW, wind turbine (WT) 690 biogas generator (BG) 100 battery (BAT) 174 kWh, an electrolyser (ELEC) 150 tank (HT) 120 kg, converter (CONV) 106.24 kW found be since it provides highest relative closeness (RC) value (∼0.817) also lowest fuel consumption rate 2.31 kg/kWh. However, system-6 shows amount CO2 (143.97 kg/year) among all studied configurations. Furthermore, detailed technical, economic, analysis conducted on optimal configuration. minimum net present (NPC), LCOE, (COH) 1 estimated $1,960,584, $0.44/kWh, $22.3/kg, respectively.

Ignore variability, overestimate hydrogen production – Quantifying the effects of electrolyzer efficiency curves on hydrogen production from renewable energy sources

International Journal of Hydrogen Energy, Journal Year: 2024, Volume and Issue: 72, P. 49 - 59

Published: May 27, 2024

This study investigates the impact of including (or neglecting) variable efficiency hydrogen electrolyzers as a function operating power in modelling green produced from renewable energy sources. Results show that neglecting electrolyzer efficiency, is commonly done studies hydrogen, leads to significant overestimation production range 5–24%. The effects time resolution used models are also investigated, well option for switch stand-by mode instead powering down and ramp rate constraints. indicate these have minor effect on overall production, with use hour data leading 0.2–2%, relative using 5-min data. three solar farms wind Australia, which it observed 55% more than farms. results this highlight critical importance production. As industry scales, continuing neglect would lead by tens megatonnes.

This study develops a new method to evaluate the economic viability of co-generation electric vehicle stations that concurrently generate electricity and hydrogen for charging battery vehicles refueling vehicles. The approach uniquely differentiates costs associated with various energy outputs in includes often-overlooked peripheral devices critical accurate evaluation levelized cost (LCOE) (LCOH). was tested across three design configurations: two featuring single storage options (battery fuel cell, respectively) third using hybrid employing both. Each configuration modeled, simulated, optimized HOMER Pro 3.14.2 determine most optimal sizing solution. Then, based on each design, LCOE LCOH were evaluated proposed this study. analysis revealed excluding could lead 27.7% error evaluation, while impact less than 1%.
