1. A method for producing hydrogen product having a carbon intensity less than about 1.0 kg CO2e/kg H2, comprising:
converting a hydrocarbon feedstock to a hydrogen product using a hydrogen production process;
providing at least some of the required energy for the hydrogen production process from a biomass power plant comprising the direct combustion of a biomass feedstock, wherein the energy produced by the biomass power plant is selected from one or more of:
(a) electricity generated from work produced by a Rankine cycle or a Brayton cycle;
(b) steam that can be used as process steam in the hydrogen production process;
(c) steam that can be used as thermal energy; or
(d) steam that can be used to power a mechanical drive; and
processing one or more gas streams containing carbon dioxide from the biomass power plant and the hydrogen production process in one or more carbon capture units to reduce CO2e emissions;
wherein the hydrogen product has a carbon intensity less than about 1.0 kg CO2e/kg H2.
