A system and method for thermal energy delivery for hydrogen (H2) gas production is disclosed. The method involves generating electricity via a solar plant and providing it to a hydrogen electrolyzer. Thermal energy from the solar plant is used to heat a primary working fluid, which transfers heat to a secondary working fluid in an evaporator, converting it into vapor. This vaporized secondary working fluid drives a turbine, generating electricity through a Rankine cycle system where the secondary working fluid circulates continuously, transmitting the secondary working fluid and a portion of the generated electricity to the hydrogen electrolyzer, which splits the secondary working fluid into H2 gas and oxygen, storing the H2 gas in a hydrogen gas storage tank. When solar power is unavailable, the stored electricity in the battery energy storage is supplied to the electrolyzer.

La generación simultánea de ácido y base permite tomar ventaja de ambos productos químicos durante la recuperación convencional de Li de salmueras y rocas minerales. El agua desalinizada también se puede usar en los pasos de lavado en el proceso de recuperación o regresar a los estanques de evaporación. El método también se puede usar para la conversión directa de sales de litio en el producto LiOH con alto valor. El método no produce ningún efluente sólido lo cual lo torna de fácil adopción para su uso en las plantas industriales de recuperación de Li existentes.
