Design, Simulation, and Sizing Assessment of an Off-Grid Solar PV–PEM Green Hydrogen Generation and Compressed Storage System for Bangladesh

Existing PV–hydrogen studies often emphasize component modeling or techno-economic assessment, while integrated Bangladesh-specific frameworks remain limited. This study develops a MATLAB/Simulink-based solar PV–PEM system
using NASA POWER solar data, integrating PV generation, MPPT-controlled DC–DC conversion, PEM electrolysis, and compressed hydrogen storage. Mathematical verification is also performed for hydrogen production and storage performance.
Although LCOH is beyond the present scope, the results indicate strong potential for solar-driven hydrogen production in Bangladesh.
