Unlocking Solar and Hydrogen Potentials: A Comparative Analysis of Solar Tracking Systems for South Africa's Energy Transition

Published: Jan. 1, 2025

This study explores the potential of solar tracking technologies to enhance South Africa's energy transition, focusing on their role in supporting green hydrogen production for domestic use and export. Using Global Energy System Model (GENeSYS-MOD), it evaluates four technologies—horizontal axis, tilted horizontal vertical dual-axis—across six scenarios: non-tracking versions a Business-as-Usual (BAU) scenario, 2°C high demand export (HighH2) scenario. The results identify axis as most cost-effective option, followed by tracking, which is particularly prominent HighH2 Tracking systems extending power output increasing electrolyzer full-load hours. In scenario they reduce costs 2050 from 1.47 €/kg 1.34 system cost 0.66%, positioning Africa competitively global market. By integrating technologies, can align ambitions with renewable growth while mitigating grid financial challenges. research underscores need targeted investments policies maximize potential, ensuring just transition that supports opportunities, security, equitable socio-economic growth.
