Resumen de: US20260088620A1
A system for producing clean hydrogen and clean hydrogen derived products using water electrolysis and time correlated renewable power whereby the operation of the electrolysis is optimized for using time correlated renewable power amongst other factors. The system includes a hydrogen production unit that uses an electrolyzer to produce hydrogen from water and electricity, where the electricity is delivered via a connection to the electrical grid and/or behind the meter renewables and whereby a control unit manages the production of hydrogen based on the attributes of the renewable power, including time correlation and other factors. The hydrogen produced from time correlated renewables may be used directly to decarbonize industrial, transportation, or other applications or the hydrogen may be used to produce hydrogen derived products such as ammonia, methanol, transportation fuels (such as sustainable aviation fuel (SAF), diesel, gasoline), LPG, chemicals, or other low carbon products that use hydrogen as an input for the production process.
