Systems and methods for conversion of a biomass into biofuel using a geothermal heat source
View Patent ↗A system for converting a biomass into a biofuel including a biomass processing station arranged to receive the biomass from a biomass harvester, output the biomass to a hydrothermal liquefaction (HTL) converter, and receive a processed biomass from the HTL converter. The system includes a conduit arranged to transport the biomass from the biomass processing station to the HTL converter and transport the processed biomass from the HTL converter to the biomass processing station. The HTL converter includes a heat exchanger arranged to transfer thermal energy from a geothermal heat source to the biomass to convert the biomass into the processed biomass. The system also includes a controller arranged to monitor conditions of the biomass at locations along the conduit and adjust operations of components along the conduit to, thereby, adjust the conditions of the biomass at one or more locations along the conduit.
1. A method for converting a biomass into a biofuel comprising:
receiving, at a biomass processing station, the biomass from a biomass harvester;
transporting the biomass from the biomass processing station to a hydrothermal liquefaction (HTL) converter via a conduit, the HTL converter being located remotely from the biomass processing station and within proximity to a geothermal heat source, wherein a portion of the conduit is located below the surface of an ocean;
transferring thermal energy from the geothermal heat source to the biomass to convert the biomass into a processed biomass, wherein the geothermal heat source is located below the surface of the ocean;
monitoring, via one or more sensors at one or more locations along the conduit, one or more conditions of the biomass at the one or more locations along the conduit;
adjusting operations of one or more components along the conduit to adjust the one or more conditions of the biomass at the one or more locations along the conduit; and
receiving, at the biomass processing station, the processed biomass from the HTL converter via the conduit.
2. The method of claim 1 comprising controlling, by a controller, the one or more conditions of the biomass by receiving sensor data from the one or more sensors associated with the one or more conditions of the biomass from the one or more sensors.
3. The method of claim 1 , wherein the biomass includes an algae and the processed biomass includes bio oil, and wherein converting the biomass includes depolymerization of the biomass to bio oil.
4. The method of claim 1 comprising adjusting the operations of the one or more components to optimize the one or more conditions of the biomass to, thereby, optimize a production yield of the processed biomass.
5. The method of claim 1 , wherein the one or more components include at least one of a pump and a flow control valve.
6. The method of claim 1 , wherein the one or more conditions of the biomass include at least one of temperature, pressure, flow rate, catalyst concentration, and residence time within the HTL converter.
7. The method of claim 1 , wherein the geothermal heat source includes at least one of a volcano, volcanic vent, and a hydrothermal vent.
8. The method of claim 1 comprising positioning the HTL converter within the ocean.
9. The method of claim 8 comprising positioning a substantial portion of the conduit within the ocean.
