Methods, systems, and devices for continuous production of liquid fuels from biomass are provided. Some embodiments utilize a thermochemical process to produce a bio-oil in parallel with a thermochemical process to produce a hydrogen-rich synthesis gas. Both product streams may be fed into a third reaction chamber that may enrich the bio-oil with the hydrogen gas, for example, in a continuous production process. One product stream may include a liquid fuel such as diesel. Some embodiments may also produce other product streams including, but not limited to, electrical power generation and/or biochar.
