Demonstrates lower hydrogen costs in renewable off-grid systems, suggesting effective energy storage strategies are crucial.

To assess the feasibility and costs of producing green hydrogen in 100% renewable, off-grid systems using a techno-economic framework.
Developed a high-resolution optimization framework
Utilized 5-minute interval meteorological data over 5 years
Co-optimized hybrid wind-solar generation and flexible electrolyzers
Implemented a multi-timescale energy storage strategy
Hybrid wind-solar systems achieved the lowest levelized cost of hydrogen (LCOH)
Multi-timescale storage reduced LCOH by up to 40%
Most favorable regions reached LCOH as low as $2.45/kg
Projection for several areas to reach LCOH of $3/kg by 2030
Inclusion of forecast uncertainty may raise costs by 5-15%

Luan et al. (2026) studied this question.
