RETRACTED: Assessing the economic feasibility of hydrogen generation from renewable energy sources

Year: 2025

Type: article

Abstract: The transition to sustainable energy systems necessitates exploring hydrogen generation from renewable energy sources (RES), yet its economic feasibility remains a critical challenge. This study assesses the economic viability of producing green hydrogen in China, focusing on the period from 2020 to 2040. A techno-economic model is employed to evaluate costs, energy inputs, and scalability, incorporating solar and wind resources as primary RES. Key findings reveal: (1) the levelized cost of hydrogen (LCOH) declines significantly by 2040, reaching $2.5–3.0/kg due to falling renewable energy and electrolyzer costs (2) regions with high solar irradiance (e.g., Northwest China); exhibit the lowest production costs; and (3) policy support, such as carbon pricing and subsidies, accelerates cost competitiveness with fossil-based hydrogen. The study underscores the need for integrated renewable-hydrogen policies, infrastructure investments, and international collaboration to unlock China's potential as a green hydrogen hub.
